## About ffmpeg-obs
# OBS Project actually patch FFmpeg to fix some issues and also add RIST support starting from 27.2.
# So I created ffmpeg-obs, a ffmpeg package that ensure that you have those.
# I really wanted to not do this but some fixes are needed, so I did my best to add those "feature-set options".
# They allow you to build ffmpeg with feature-set based on other ffmpeg packages from AUR.

### Feature-set options
### WARNING: There is no arch check so don't enable one without knowing if the feature-set is compatible with your arch.
### The license could change to nonfree for some options.
### NOTE: Some AUR helper may not like to change it just before building, so you can set those variables in your makepkg config.
### Related wiki page: https://wiki.archlinux.org/title/Makepkg#Configuration

## Add changes from ffmpeg-full
## Enable everything except CUDA changes (enable it manually if you want it)
if [[ -z "$FFMPEG_OBS_FULL" ]]; then
  FFMPEG_OBS_FULL=OFF

## Based on changes from ffmpeg-cuda
## If 'ON', CUDA compilation is made with Nvidia CUDA Compiler, this is what ffmpeg-cuda provides. (nonfree option)
## If 'OFF', CUDA compilation is made with clang (without cuda package), this is what upstream package provides.
if [[ -z "$FFMPEG_OBS_CUDA" ]]; then
  FFMPEG_OBS_CUDA=OFF

## Enable debugging symbols
if [[ -z "$FFMPEG_OBS_DEBUG" ]]; then

## Add changes from ffmpeg-decklink (nonfree option)
if [[ -z "$FFMPEG_OBS_DECKLINK" ]]; then
  FFMPEG_OBS_DECKLINK=OFF

## Add changes from ffmpeg-libfdk_aac (nonfree option)
if [[ -z "$FFMPEG_OBS_LIBFDK_AAC" ]]; then
  FFMPEG_OBS_LIBFDK_AAC=OFF
fi

## Add SVT related changes from ffmpeg-full because ffmpeg-svt is out of date
if [[ -z "$FFMPEG_OBS_SVT" ]]; then
  FFMPEG_OBS_SVT=OFF
fi

## Add changes from ffmpeg-vulkan (now only enables libglslang since vulkan is enabled upstream)
