# VidDraw - record video as you draw
**VidDraw** is a Windows program that records a video of a canvas as you
draw on it. Recording starts when you begin drawing and stops when you’re
no longer holding down any mouse buttons.The main goal of VidDraw is to demonstrate using
[SharpAvi](https://github.com/baSSiLL/SharpAvi) (which wraps
[VfW](https://learn.microsoft.com/en-us/windows/win32/api/vfw/)) to record a
canvas, [toast
notifications](https://learn.microsoft.com/en-us/windows/uwp/design/shell/tiles-and-notifications/send-local-toast?tabs=uwp),
and [embedded
browsing](https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.webbrowser?view=windowsdesktop-6.0).
It began as a prototype for the video-recording feature of a larger program
I’ve been working on. It’s also kind of a fun toy.This is **VidDraw alpha 5**. It still has [some usability
bugs](#known-bugs).## License
VidDraw is [free software](https://en.wikipedia.org/wiki/Free_software).
Its own code [is licensed](COPYING.0BSD) under
[0BSD](https://spdx.org/licenses/0BSD.html) (“Zero-Clause BSD
License,” also known as the [Free Public License
1.0.0](https://opensource.org/licenses/0BSD)), which is a [“public domain
equivalent”](https://en.wikipedia.org/wiki/Public-domain-equivalent_license)
license. VidDraw’s dependencies are also free, but they are offered
under other licenses. See [Dependencies](#dependencies) below for details.Since some of VidDraw’s dependencies are included directly in this
repository, some of the files in this repository have other authors and are
licensed under terms other than 0BSD. See [`LICENSE`](LICENSE) and
[Notices](#notices).## Setup
This alpha version of VidDraw doesn’t have binary downloads, so it
must be built from source. You’ll need the [.NET
6](https://dotnet.microsoft.com/download/dotnet/6.0) SDK (or higher). To clone
the repository and build VidDraw, run:```powershell
git clone https://github.com/EliahKagan/VidDraw.git
cd VidDraw
dotnet build
```Then, to run the program:
```powershell
dotnet run
```Those commands build and run a “debug” build. If you want a
“release” build instead, use `dotnet build -c Release` and
`dotnet run -c Release`.Dependencies not included in this repository will be [downloaded
automatically](https://www.nuget.org/). Running [`dotnet
run`](https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-run) without
first running [`dotnet
build`](https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-build) also
works, though if you do that the first time, it may appear to have frozen for a
short while as dependencies are downloaded. (In contrast, `dotnet build` is
more verbose.)If you prefer to open the solution file `VidDraw.sln` in Visual Studio 2019 and
build VidDraw from there, that is also supported.That’s all you need. If you want to read about codec stuff… read
on! Otherwise, you may want to skip to [Usage Tips](#usage-tips) or [The
Menu](#the-menu), or just try out the program.### Optional: Get x264vfw for H.264 support
If you want VidDraw to be able to encode H.264 video, you’ll need
[x264vfw](https://sourceforge.net/projects/x264vfw/). You don’t have to
install that before VidDraw, though. You can even install it while
VidDraw is already running, and H.264 will be ungrayed in
VidDraw’s menu.In the x264vfw configuration, you should check the box for “Zero
Latency” [to avoid picture
freezes](https://bassill.github.io/SharpAvi/using-video-encoders.html#mpeg-4)
while encoding video in real time. Note that the 32-bit and 64-bit x264vfw
codecs are configured separately; changing the configuration for one
doesn’t affect the other.x264fw’s installer creates “Configure x264vfw” and
“Configure x264vfw64” shortcuts (or just one, if you told it to
install the codec for just one architecture or you’re on a 32-bit
system). Besides those shortcuts, another way to open the x264vfw configuration
dialog is from the menu in VidDraw: so long as x264vfw is installed for
the same architecture as the running VidDraw process, a “Configure
x264vfw (x86)” or “Configure x264vfw (x64)” menu item will
appear.### A problem with H.264 in VidDraw
Encoding with H.264 produces much smaller files than Motion JPEG, which is
VidDraw’s default and itself much smaller than encodings without any
compression. But I’ve found that these H.264-encoded files—files
recorded in real time in the way VidDraw records them, *not* H.264 video
in general—are not playable on all players. [This may be due to a bug in
VidDraw, but I’m not
sure.](#video-files-are-not-always-playable-on-all-players) The excellent and
very popular VLC does not play them. Windows Media Player and the Movies & TV
app (and also [MPC-HC](https://mpc-hc.org/)) do play them.Other than just using Motion JPEG instead (or waiting until VidDraw is out
of alpha?), there are a couple workarounds to produce a video that VLC will
play:#### Configure x264vfw to make every frame a keyframe
At the cost of considerably larger files (but still not as big as Motion JPEG),
making every frame a [keyframe](https://en.wikipedia.org/wiki/Key_frame) fixes
the problem in VLC. To do that, open the x264vfw configuration dialog
and—in the textarea labeled “Extra command line (for advanced
users)”—put:```sh
--keyint 1
```*See [x264vfw Compression - WTF am I doing
wrong?](https://forums.guru3d.com/threads/x264vfw-compression-wtf-am-i-doing-wrong.373036/)
on the [Guru3D.com](https://www.guru3d.com/) forums.*#### Post-process the video with FFmpeg
Given a video from VidDraw that VLC cannot open,
[FFmpeg](https://ffmpeg.org/) will repair it:```powershell
ffmpeg -err_detect ignore_err -i "VidDraw capture 2021-05-08 16-38-04.avi" -c copy "VidDraw capture 2021-05-08 16-38-04 fixed.avi"
```You would run that from the `Videos` folder (where VidDraw saved the
file). Change `VidDraw capture 2021-05-08 16-38-04.avi` to the actual name of
the file VidDraw created. The second filename names FFmpeg’s output
file; put whatever you like for that.*See [Gyan](https://video.stackexchange.com/users/1871/gyan)’s
[answer](https://video.stackexchange.com/a/18226) to [Fix bad files and streams
with ffmpeg so VLC and other players would not
crash](https://video.stackexchange.com/questions/18220/fix-bad-files-and-streams-with-ffmpeg-so-vlc-and-other-players-would-not-crash)
on [Video Production Stack Exchange](https://video.stackexchange.com/).*### Optional: Regenerate the Documentation
If you’re just building and using VidDraw, and not modifying
it—or modifying it but not modifying its documentation—you can skip
this section.VidDraw comes with `doc\index.html`. Building VidDraw as described
above places a copy of that file (and some others) in the build output
directory, which the program’s [built-in help viewer](#about-viddraw)
displays. `doc\index.html` is itself generated from `README.md`, and building
VidDraw does not regenerate it. If you’re hacking on VidDraw
and you make changes to `README.md` or to files in the `pandoc` directory, then
you should regenerate it by running the `generate.cmd` script in the `pandoc`
directory:```powershell
pandoc\generate.cmd
```(That assumes you are in the repository’s top-level directory.)
If you’re on a Unix-like operating system or otherwise using a Unix-style
shell, such as Bash, use the `generate` shell script instead:```sh
pandoc/generate
```Note that while building VidDraw’ and generating its documentation
are supported on Windows, GNU/Linux, and macOS, *running* VidDraw’
is only supported on Windows systems.On 64-bit Windows systems, if you don’t have
[Pandoc](https://en.wikipedia.org/wiki/Pandoc), one way to install it is with
[Scoop](https://scoop.sh/):```powershell
scoop install pandoc
```Modifications to files other than `README.md` and those in the `pandoc`
directory do not require `doc\index.html` to be regenerated.## Usage Tips
VidDraw’s interface is meant to be clean and simple, but in some
ways it is confusing. It may be improved in the future. For now, maybe some of
the following information will help.### Drawing and Recording
**Draw** as you would in any raster graphics editor.
When the mouse cursor is over the canvas and you press the primary mouse
button, recording begins. Moving the mouse while the primary mouse button is
pressed draws on the canvas. Recording continues until you release the button.Even pressing the primary mouse button for a very short time records a video. A
single short click is sufficient, though the video may consist of only one
frame.You will know VidDraw is recording because the border around the canvas
turns bright red. As long as it is red, VidDraw is recording. When it
turns back to light gray, recording has stopped and the video file is fully
saved.![Screenshot of a corner of the VidDraw window while recording, showing the red
border](doc/recording.png)**To lift the pen while continuing to record**, press and hold another mouse
button. So long as at least one button is pressed, recording continues. This
lets you make a video of drawing a sketch with multiple disconnected strokes.If you ever want to continue recording while no mouse buttons are pressed,
place the mouse cursor on the canvas, press and hold any mouse button, drag the
cursor out of the canvas, press any other mouse button, then release both
buttons (in either order). This effect, of keeping recording on even though
you’re not holding down any mouse button, persists until your next
interaction with the canvas. So, to stop recording, click the canvas. (If you
don’t want to draw anything, click it with some button other than the
primary mouse button.) Or you can resume drawing, and the next time you release
all mouse buttons, recording will stop.When recording has stopped and the border has turned back from red to gray, the
file is fully saved and should be playable, whether VidDraw is still
running or not. Conversely, it is fine to quit while still recording.
VidDraw stops recording and cleanly saves the file on exit.The pen color can be changed using [the color picker](#pick-color), available
in [the menu](#the-menu).The canvas in VidDraw is always 800×600.
### Save Location and Toast Notifications
VidDraw saves files in your Videos folder. The location of this folder is
configurable per-user in Windows, but by default it is the folder called
`Videos` and located directly in your home folder.When a recording ends (while VidDraw is still running), VidDraw
raises a [toast
notification](https://en.wikipedia.org/wiki/Pop-up_notification) informing you
of the filename as well as the encoding that was used for the video. Clicking
this notification opens a file browser (i.e., Explorer) window for the
destination folder, with the newly finished video selected.VidDraw names files by the date and time at which it *started* recording
them. The filenames consist of `VidDraw capture` followed by the date and time,
like `VidDraw capture 2021-05-09 21-49-12`. (The ugly hyphen-delimited time is
because Windows filesystems like NTFS don’t support colon characters in
filenames.) This file exists immediately once recording has started, though it
may not be playable—and is not guaranteed to be openable by other
applications—until recording is completed.Since clicking the notification opens the destination folder and selects the
file, you can rename it easily to whatever name you actually want it to have.Quitting VidDraw clears any notifications that have not been clicked or
dismissed. *Unless* you were running multiple instances of
VidDraw—in that case, they all stick around until the last instance
is closed. *Unless* some instances are running in 64-bit mode while others are
running in 32-bit mode—in that case, quitting the last 64-bit instance
clears any remaining notifications from 64-bit instances, while quitting the
last 32-bit instance clears any remaining notifications from 32-bit instances.VidDraw is only able to raise toast notifications on Windows 10, version
10.0.17763 or later. If VidDraw can’t raise toast notifications on
your system, it falls back to opening the Explorer window immediately when
recording finishes. But if VidDraw can’t show you a notification
because you’ve configured notifications in Windows 10 not to show them
(or turned them off), then VidDraw does *not* try to circumvent this by
showing a file browser window. In that case, nothing special happens when
recording finishes.You can always open the destination folder by clicking “Open Videos
Folder” [in VidDraw’s menu](#the-menu).## The Menu
VidDraw augments its *system menu*—the application menu that you can
open by left- or right-clicking on the left side of the title bar,
right-clicking anywhere on the title bar, or pressing
Alt+Space, and that contains standard items like
“Move” and “Close”—with [encoding
choices](#encoding-codec-choices) and some [other
operations](#other-stuff-in-the-menu) specific to VidDraw.![Screenshot of augmented system menu in VidDraw](doc/menu.png)
Some menu items change settings. These changes are saved in a `VidDraw`
subdirectory of your per-user application data (`%APPDATA%`) directory, which
is usually `%USERPROFILE%\AppData\Roaming` (where `%USERPROFILE%` is your home
directory).### Encoding (“Codec”) Choices
There are currently four video encodings available. The selected encoding has a
check mark to the left of it in the menu. Exactly one is selected at any given
time.Please note that this doesn’t affect the file format, i.e., container
filetype, which is always AVI. Rather, it affects the encoding of the video
stream.Your codec choice is remembered across runs of the program.
#### Raw (frame copy)
This is the worst possible encoding and I don’t recommend using it. Each
bitmap is captured from the canvas as-is, including the alpha channel data (the
“A” in “ARGB”). The canvas, and the recorded video
stream, use different conventions for the order in which each line (row of
pixels) is stored, so this order is reversed; otherwise, it is a raw
“frame copy.”The only reason I put this in VidDraw was to demonstrate how to write
video frames in SharpAvi without an
[encoder](https://bassill.github.io/SharpAvi/using-video-encoders.html#using-video-encoders).
But you should use an encoder. If you want uncompressed video, I recommend
using [Uncompressed](#uncompressed) instead, which leaves out the unused alpha
channel.#### Uncompressed
If you want uncompressed video (where each frame is a bitmap), you should use
this. It uses SharpAvi’s `UncompressedVideoEncoder`. As the
[SharpAvi
docs](https://bassill.github.io/SharpAvi/using-video-encoders.html#uncompressed)
say:> The simplest \[encoder\] is the `UncompressedVideoEncoder`. It does no real
> encoding, just flips image vertically and converts BGR32 data to BGR24 data
> to reduce the size.Video files created this way are quite large, if you’re recording for
more a few seconds. If you’re keeping videos you create this way, you may
want to encode them with a compressed codec afterwards. If your hard disk is
slow, you may experience lag while encoding this way. It’s still better
than [Raw (frame copy)](#raw-frame-copy), though.#### Motion JPEG
[Motion JPEG](https://en.wikipedia.org/wiki/Motion_JPEG) is
VidDraw’s default encoding. Each frame is converted to and stored as
a JPEG image. This uses SharpAvi’s `MotionJpegVideoEncoderWpf`. From
the [SharpAvi
docs](https://bassill.github.io/SharpAvi/using-video-encoders.html#motion-jpeg):> Next is the `MJpegWpfVideoEncoder` which does Motion JPEG encoding. It uses
> `System.Windows.Media.Imaging.JpegBitmapEncoder` under the hood. Hence
> it’s only available in Windows targets. Besides dimensions, you provide
> a desired quality level to its constructor, ranging from 1 (low quality,
> small size) to 100 (high quality, large size).VidDraw uses a quality of 100, since the pen in VidDraw makes
1-pixel-thick curves, and lower qualities of Motion JPEG (like the oft-used 70)
tend not to render such curves crisply.The file size is unhappily large, but nowhere near as bad as the uncompressed encodings.
#### H.264 (MPEG-4 AVC)
If the [x264vfw](https://sourceforge.net/projects/x264vfw/) codec (of the same
architecture as the VidDraw process) [is
installed](#optional-get-x264vfw-for-h264-support), the menu item for
[H.264](https://en.wikipedia.org/wiki/Advanced_Video_Coding) is unfaded. It
isn’t the default because VidDraw doesn’t ship that codec and
you may not already have it, and because there are [configuration choices for
you to make](#a-problem-with-h264-in-viddraw) and [playback issues to wrangle
with](#video-files-are-not-always-playable-on-all-players).Still, I recommend encoding in H.264 if you can, because it produces higher
quality than [Motion JPEG](#motion-jpeg) at a small fraction of the file size
(*even* if you use
[`--keyint 1`](#configure-x264vfw-to-make-every-frame-a-keyframe)).The [SharpAvi
docs](https://bassill.github.io/SharpAvi/using-video-encoders.html#mpeg-4) say:> Finally, the `Mpeg4VcmVideoEncoder` does MPEG-4 encoding using a *Video for
> Windows* (aka *VfW*) or *Video Compression Manager* (aka *VCM*) compatible
> codec installed on the system. Apparently, this encoder works on Windows only
> (but is available for any target).
>
> Currently tested codecs include **Microsoft MPEG-4 V2** and **V3**,
> [Xvid](https://www.xvid.com/download/),
> [DivX](http://www.divx.com/en/software/divx) and
> [x264vfw](http://sourceforge.net/projects/x264vfw/files/). Unfortunately,
> some of them have only 32-bit versions, others produce errors in 64 bits. The
> only codec which looks to work reliably in 64 bits is **x264vfw64**.
>
> ***Tip.*** For **x264vfw** (both 32- and 64-bit), it is recommended to check
> the option **Zero Latency** in its configuration utility to prevent picture
> freezes. This configuration utility is installed along with the codec.### Other Stuff in the Menu
#### Clear Canvas
If the canvas has not been drawn on since opening SharpAvi, or since the
last time it was cleared, then the “Clear Canvas” option is
unfaded. This clears the canvas, making all pixels white, as they started.#### Pick Color…
The pen color is black by default. “Pick Color…” opens a
color picker in which you can choose another color. The color picker is based
on
[`ColorDialog`](https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.colordialog?view=windowsdesktop-6.0),
which wraps the [standard Windows color dialog
box](https://learn.microsoft.com/en-us/windows/win32/dlgbox/color-dialog-box)
and, as such, allows you to define custom color presets. VidDraw saves
your custom colors, so they are available if you quit VidDraw and run it
again. Your custom VidDraw colors do not appear in any other
programs’ color dialogs.(Unfortunately, defining custom colors but cancelling out of the color picker
discards the new custom colors—you have to click “OK.” Since
this is what users familiar with the Windows color dialog expect, I don’t
think I should try to change it for VidDraw’s color picker.)#### Open Videos Folder
Clicking “Open Videos Folder” opens the destination folder where
VidDraw saves videos. This is your per-user `Videos` (or `My Videos`)
directory.This is handy if you meant to click to activate a toast notification after
recording, but dismissed it instead.In the strange case that you record a video and, while VidDraw is still
running, change the location of your per-user `Videos` folder, this goes to the
new place, not the old one. (The new location is the destination for any
further videos VidDraw saves, even during the same run of the program.)#### Download x264vfw
*or* Configure x264vfw (x64)
*or* Configure x264vfw (x86)If x264vfw is not installed, or it is installed but not for the same
architecture as the VidDraw process, then VidDraw cannot use it. In
this case, the menu contains a “Download x264vfw” item that opens
the x264vfw download page in your web browser.If x264vfw is installed for the architecture of the VidDraw process, then
VidDraw can use it, and the menu contains either a “Configure
x264vfw (x64)” or “Configure x264vfw (x86)” item, depending
on the architecture of the VidDraw process (i.e., whether it’s
running as a 64-bit process or a 32-bit process, respectively).Clicking “Configure x264vfw” opens x264vfw’s own
configuration dialog. This dialog is not part of VidDraw, and
configuration changes you make in it affect x264vfw on your whole system; they
are not specific to VidDraw. But they *are* specific to the 64-bit (x64)
or 32-bit (x86) version of x264vfw. By default, all remotely recent versions of
x264vfw install both the 64-bit and 32-bit codecs. They must be configured
separately.#### About VidDraw…
Clicking “About VidDraw…” displays this README in
VidDraw’s built-in help browser.This help browser’s own system menu contains items for opening the README
externally in your default web browser, for visiting the repository on GitHub,
and for navigation (equivalent to the page’s own left sidenav).## Known Bugs
### Sometimes there is an initial lag on the first recording.
This seems to happen mainly while debugging—even a debug build that is
being run (via `dotnet run` or by directly running the compiled executable) is
most often free of it. But it seems to happen occasionally even outside of
debugging.This is annoying because, when it happens, it usually results in a straight
line segment appearing on the canvas (and in the video) that the user
didn’t intend to draw.VidDraw could do some operations asynchronously that it now does on the UI
thread. Most or all file I/O could, and should, be asynchronous. Implementing
this will require thought about what to do in some race conditions that cannot
currently happen.I don’t know if that would be sufficient to fix this bug.
### Video files are not always playable on all players.
[As detailed above](#a-problem-with-h264-in-viddraw), when H.264 encoding is
selected and x264vfw has not been configured to make every frame a keyframe
(which increases file size dramatically, albeit still less than the other
encodings), VLC cannot play the file. This is even though VLC fully supports
H.264 (and manages to play even most broken H.264 videos). It may be a problem
with the way I’ve configured x264vfw. But [FFmpeg](https://ffmpeg.org/)
is able to repair the files, and it reports problems with them, so I think this
is a bug.I can produce this problem (on the same system) with the SharpAvi sample
application—both the [upstream
version](https://github.com/baSSiLL/SharpAvi/tree/master/Sample) targeting the
[upstream SharpAvi](https://www.nuget.org/packages/SharpAvi/) and [my
forked version](https://github.com/EliahKagan/SharpAvi/tree/net5/Sample)
targeting [the fork of
SharpAvi](https://www.nuget.org/packages/SharpAvi.Net5) that VidDraw
uses. But it remains unclear to me, due to its sensitivity to x264vfw settings,
whether it is due to a bug in SharpAvi. I can also produce it in the
SharpAvi sample application with [Xvid](https://www.xvid.com/) (but,
likewise, this might turn out to be because of how I have Xvid configured).### The help’s sidenav can be unexpectedly in “mid-fade.”
Narrowing the viewport fades the navigational sidebar out; widening fades it
in. Whether or not it is faded, and how faded, is determined solely by (scaled)
viewport width. This works okay when the user resizes the window. But it is
possible for the viewport to *start* with a “transitional” width at
which the sidebar is present but faded. In that case, the user is likely to
think either that the sidebar is meant to look this way (i.e., poorly designed)
or that a bug causes it to appear this way (either always, or under limited but
unclear circumstances).This isn’t all that likely to happen in VidDraw’s own help
viewer. But general-purpose web browsers don’t start out with a
predetermined (scaled) size selected to make this specific page look
reasonable. The help file—and its sidenav—is meant to be fully
usable on web browsers, too.### Menu items are cumbersome to access while drawing.
Some operations that users are likely to want to do while
recording—especially opening the dialog box to change the pen
color—should have keyboard shortcuts but do not. Some design choices have
to be made to implement this correctly: if the user presses a key combination
that opens a modal dialog box, should recording automatically continue after
the dialog box exits?### It might be useful to be able to pause.
VidDraw’s user experience is intended to be simple and spontaneous,
so I haven’t included any option to pause and unpause recording. If
recording *ever* pauses, then users are likely to assume, and some may prefer,
that opening a modal dialog box or changing focus to another application will
pause it. So, if pausing is added, options to enable (and disable) automatic
pausing in those situations should be added too.Fixing this may help with [Menu items are cumbersome to access while
drawing](#menu-items-are-cumbersome-to-access-while-drawing) as well.### The pen thickness should be adjustable in some way.
Being able to vary the pen’s size would make drawing more fun.
This could be done by holding down modifier keys (Shift,
Ctrl, Alt) and/or by selecting something in the menu.### User experience on older Windows could be better.
#### Awkward toast fallback
Although it is not a goal for VidDraw to fully support any versions of
Windows older than 10.0.17763, it might be good to come up with some other
behavior than immediately opening the destination folder each time on systems
that don’t support toast notifications.#### Thin title bars
Old Windows operating systems, such as Windows 7, have very thin title bars, at
least when styling is turned off or classic styling is used. This makes the
border around the canvas (which turns red to indicate recording) look
excessively thick. It’s probably not worth it to detect and handle this
situation, but perhaps there’s some simple way.## Dependencies

([inline](#windows-community-toolkit))VidDraw is a C# program targeting [.NET](https://dotnet.microsoft.com/) 6
on Windows. It uses [Windows Forms](https://github.com/dotnet/winforms), and it
makes calls to the [Windows API](https://en.wikipedia.org/wiki/Windows_API) via
libraries such as SharpAvi and Windows Forms as well as directly.
Components that I believe are considered part of the framework (.NET) or
operating system (Windows) are not listed above.Indirect dependencies (dependencies of the above-listed dependencies that are
either included in them or otherwise resolved through them) are also not
listed.### VidDraw and x264vfw
VidDraw does not depend on
[x264vfw](https://sourceforge.net/projects/x264vfw/) but is capable of using it
[if it is installed](#optional-get-x264vfw-for-h264-support). x264vfw is a
[VfW](https://en.wikipedia.org/wiki/Video_for_Windows) codec for
[H.264](https://en.wikipedia.org/wiki/Advanced_Video_Coding) by Anton
Mitrofanov and other authors, derived from
[x264](https://www.videolan.org/developers/x264.html). Since, when installed
and selected in VidDraw, it greatly reduces file size while preserving
quality, I’m thankful to all the developers of x264vfw and x264 for the
work they’ve done. Per its
[COPYING](https://sourceforge.net/p/x264vfw/code/HEAD/tree/trunk/COPYING) file
and license headers in most of [its source code
files](https://sourceforge.net/p/x264vfw/code/HEAD/tree/trunk/), x264vfw is
licensed under [the GNU GPL v2 or
later](https://spdx.org/licenses/GPL-2.0-or-later.html).VidDraw uses x264vfw via SharpAvi in a manner analogous to how any
VfW codec may be used, doesn’t itself include the codec, and interacts
with it [at arm’s
length](https://www.gnu.org/licenses/gpl-faq.en.html#MereAggregation) (VfW
codecs are shared libraries, but as I understand it, programs that use them
don’t link to them or directly call API functions that they define). So I
believe the GPL does not require that VidDraw or any of the libraries
VidDraw uses be offered under the GPL or have a GPL-compatible license.Please note that, for practical and ideological reasons unrelated to x264vfw, I
still intend VidDraw to be GPL-compatible! If it is not, or even if it
appears not to be, I’d consider that a serious bug.## Notices
