A couple of similar questions are on stackoverflow, but I haven't been able to figure this exact problem out.
I want to get a list of the fourccs for the avi codecs that FFMpeg can decode.
I know how to get all the formats ffmpeg -formats and codecs ffmpeg -codecs but neither list gives me an accessible list of fourccs. Neither does the documentation I can find.
I need this list, so that my application can access the fourcc of an avi file and determine whether to use ffmpeg or VfW (or DirectX) to try decode the file.
Is there some ffmpeg command that can give me this list?
