## GSTH266Enc: A Gstreamer Plugin for VVC Encoder
An open-source GStreamer Plugin for VVC encoder (h266enc)
This plugin is still under development and will continue to improve by:
1. extending the API layer to support other known or future VVC encoder implementations
2. exposing additional encoder properties
3. extending support to other platforms (e.g. linux)
4. ...
## Plugin Architecture
Following is a pictorial representation of the Gstreamer plugin architecture
## Prerequisites
Prerequisites for building the Gstreamer plugin on Windows are:
- Visual Studio 19 (for MSVC compiler (version 19.29.30038.1))
- meson (version 0.59.0)
- Gstreamer (version 1.20.1)
- VVC encoder library
VVC encoder libraries currently supported by the plugin are:
- VVenC v1.4.0 - https://github.com/fraunhoferhhi/vvenc
- UVG266 v0.4.1 - https://github.com/ultravideo/uvg266
## Installation
### MSVC compiler
The MSVC compiler is available as part of the visual studio for windows installation. A different C/C++ compiler for windows can be used but is not tested.
### Meson
To install Meson, follow the instructions on https://mesonbuild.com/Getting-meson.html
Python 3.7 or up is required for meson.
### GStreamer
1. Download the Runtime and Development installer. The installers are available under the following [link](https://gstreamer.freedesktop.org/data/pkg/windows/). In this project we are using x64.
- We are developing this project against Gstreamer 1.20.1. To download the installers for Gstreamer 1.20.1 show the [link](https://gstreamer.freedesktop.org/data/pkg/windows/1.20.1/msvc/)
- More information on installation of Gstreamer on Windows is available on the [official website](https://gstreamer.freedesktop.org/documentation/installing/on-windows.html#download-and-install-gstreamer-binaries)
2. Run the installers. You will be prompted with details on where to install `gstreamer`, usually it is in `C:\`
- running the devel package will prompt you with three options ie. `Typical`, `Custom`, `Complete`
- choose the complete installation to install pkgconfig files
3. Setting the environment varibles: (assuming gstreamer is installed in C:\)
- Add `C:\gstreamer\1.0\msvc_x86_64\bin` to PATH
- Set `PKG_CONFIG_PATH` to `C:\gstreamer\1.0\msvc_x86_64\lib\pkgconfig`
- Set `GSTREAMER_ROOT_X86_64` to `C:\gstreamer\1.0\msvc_x86_64`
4. Reboot your system
5. Open terminal and check `gst-launch-1.0`
### VVC encoder library
#### VVenC
- Checkout the latest code from [here](https://github.com/fraunhoferhhi/vvenc).
- Follow the [build](https://github.com/fraunhoferhhi/vvenc/wiki/Build) process to generate the shared library (vvenc.dll)
- install the vvenc.dll to the GStreamer install directory under `C:\gstreamer\1.0\msvc_x86_64\bin\`
#### UVG266
- Checkout the latest code from [here](https://github.com/ultravideo/uvg266)
- Follow the [build](https://github.com/ultravideo/uvg266#compiling-uvg266) process to generate the shared library (uvg266.dll)
- install the generated uvg266.dll to the Gstreamer install directory under `C:\gstreamer\1.0\msvc_x86_64\bin\`
## Compiling the GSTH266enc plugin
Plugin is compiled using meson build system. The plugin is only tested on a 64-bit windows machine.
Run the following commands in the root directory to generate the plugin and API libraries
```
mkdir builddir
cd builddir
meson ../.
-DENCODER_TYPE=
-DENCODER_LIB_PATH=
-DENCODER_INCLUDE_PATH=
meson compile -C .
```
For example, to configure the meson to compile the plugin with VVenC library:
```
meson ../. -DENCODER_TYPE=VVENC -DENCODER_LIB_PATH= -DENCODER_INCLUDE_PATH=
```
Similarly, to configure the meson to compile the plugin with UVG266 library:
```
meson ../. -DENCODER_TYPE=UVG -DENCODER_LIB_PATH= -DENCODER_INCLUDE_PATH=
```
After successful compilation, following shared libraries are generated that need to be copied to the Gstreamer installation directory:
- gsth266enc.dll (under builddir/plugin/ directory)
- This is copied to the GStreamer-1.0 lib directory at `C:\gstreamer\1.0\msvc_x86_64\lib\gstreamer-1.0\`
- _lib.dll depending on the encoder type (under builddir/encoders/_utils/) where encoder_type={vvenc or uvg}
- This is copied to the GStreamer-1.0 bin directory at `C:\gstreamer\1.0\msvc_x86_64\bin\`
In the next section, we demonstrate the usage of the plugin
## Usage of the plugin
One can inspect the h266enc element using the `gst-inspect-1.0` utility provided by Gstreamer as follows
```
gst-inspect-1.0 h266enc
```
Following are the pad templates supported by the plugin:
```
Pad Templates:
SINK template: 'sink'
Availability: Always
Capabilities:
video/x-raw
framerate: [ 0/1, 2147483647/1 ]
width: [ 1, 2147483647 ]
height: [ 1, 2147483647 ]
format: { (string)I420, (string)I420_10LE }
SRC template: 'src'
Availability: Always
Capabilities:
video/x-h266
framerate: [ 0/1, 2147483647/1 ]
width: [ 16, 2147483647 ]
height: [ 16, 2147483647 ]
stream-format: byte-stream
alignment: au
profile: { (string)main-10 }
```
Following are the supported element properties:
```
Element Properties:
bitrate : Bitrate in kbit/sec
flags: readable, writable, changeable in NULL, READY, PAUSED or PLAYING state
Unsigned Integer. Range: 1 - 102400000 Default: 10000000
min-force-key-unit-interval: Minimum interval between force-keyunit requests in nanoseconds
flags: readable, writable
Unsigned Integer64. Range: 0 - 18446744073709551615 Default: 0
name : The name of the object
flags: readable, writable, 0x2000
String. Default: "h266enc0"
parent : The parent of the object
flags: readable, writable, 0x2000
Object of type "GstObject"
qos : Handle Quality-of-Service events from downstream
flags: readable, writable
Boolean. Default: false
qp : QP for P slices in (implied) CQP mode (-1 = disabled)
flags: readable, writable
Integer. Range: -1 - 51 Default: 32
```
To test the element, a GStreamer tool named ‘gst-launch’ can be used to test a simple pipeline as shown in figure below.
Note that in the above case the GST plugin is configured to use the VVenC encoder. The above pipeline can be tested using the following command:
```
gst-launch-1.0 videotestsrc ! video/x-raw,format=I420_10LE, width=256,height=256 ! h266enc bitrate=1000000 ! filesink location=videotestsrc.266
```
