# ffavc
ffavc is a video decoder built on ffmpeg which allows libpag to use ffmpeg as its software decoder
for h264 decoding.
## Dependency management
Go to the root directory of ffavc project, use the following command to pull the third-party library：
```
git submodule update --init
```
## Build ffmpeg
First, make sure you have built the ffmpeg vendor libraries.
### Windows platform
1. Install Visual Studio 2019.
2. Install [mysy2](https://www.msys2.org/)
3. Install some dependencies
```
pacman -S make gcc diffutils mingw-w64-{i686,x86_64}-pkg-config mingw-w64-i686-nasm mingw-w64-i686-yasm
```
4. Rename msys64/usr/bin/link.exe to msys64/usr/bin/link.bak, to avoid conflict with MSVC's link.exe
5. Run "VS2019 x86 Native Tools Command Prompt" (Run "VS2019 x86_x64 Native Tools Command Prompt"
for 64-bit.)
6. Go to the mingw installation directory and run, (usually located in C:\workspace\windows\msys64):
```
msys2_shell.cmd -mingw32 -use-full-path (-mingw64 for 64-bit)
```
7. Finally, go to the root directory of ffavc project, run:
```
build_ffmpeg.sh
```
### Web platform
1. Go to the root directory of ffavc project, run:
``` bash
build_ffmpeg.sh
```
2. Go to the root directory of web/script directory, run:
``` bash
build.sh
```
### Other platforms
Go to the root directory of ffavc project, run:
```
build_ffmpeg.sh
```
The script will generate ffmpeg libraries to `vendor/ffmpeg` directory.
## Build ffavc
After ffmpeg libraries are built, you can open this project by CLion to build, or simply build it
with the cmake command-line tool.
