Upon closer inspection, it does seem that raw ffmpeg is around 50% faster indeed, if NEON support is enabled. With VLC however, FFMPEG MPEG2 decoding is horribly jittery - freezing every so often. I do not know why, and I have neither time nor skills to investigate this. Anyway that's orthogonal to optimizing libmpeg2. -- Rémi Denis-Courmont ------------------------------------------------------------------------------ Come build with us!
