Greetings! This small patch is required for high color 15-bit Westwood VQA3 videos to be decoded properly. It just saves an offset of a VQFL chunk when it sees one and then concatenates it with the packet of a later VQFR chunk that contains full frame data. This way the (yet-to-be-merged) VQA3 decoder can apply the updated codebook before rendering a new frame and each packet contains a standalone frame, as expected.
This change was already added by Adam Iglewski as part of GSoC 2009: https://lists.ffmpeg.org/pipermail/ffmpeg-devel/2009-May/075047.html However that patch had a memory leak with the dynamically allocated memory: https://lists.ffmpeg.org/pipermail/ffmpeg-devel/2009-May/075154.html Here that problem is avoided because no heap allocation is done. One question though: is it a problem that I use avio_seek() to rewind the stream? _______________________________________________ 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".
