Sent a patch with some notes on this. > Are there any limitations to loopback decoding e.g. would a vpx w/alpha > encode be decoded back to a alpha pix fmt? I don't know how vpx alpha works, was it a separate stream in the demuxer or something like that? Loopback decoders work exactly like normal decoders, except their packets arrive from an encoder instead of a demuxer. -- Anton Khirnov _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
