I need to take in mp4 video and access separate decoded image frames in memory and analyse them for statistics. Can anyone direct me to some example code which could be used as a start point for me - or alternatively, point me to somewhere in the source where the frames are available in memory decompressed? I had a quick look at output_example and I'm not even sure I understand what it is trying to achieve - e.g. what is its input?
As an aside, I am currently using ffmpeg to convert the mp4 input into separate files (for analysis) using the output formatter 'image2' - but this is far too slow (particularly for non-compressed output). Is there a way to adjust the level of jpg compression in the output? _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
