This code is not very readable, due to the ugly c++ coding style and bloat. > If I have a test clip that is 30 frames, 30fps long, for some reason the > lib always extracts only 24 frames and then says end of file. If I read it correctly, you are forgetting to flush the decoder after the end of the stream. You have to feed empty packets to the decoder until it returns no frame. Note: the decoding example seems slightly invalid for that. Please remember not to top-post on this mailing list; if you do not know what it means, look it up. Regards, -- Nicolas George
