Hi there, I compared h264_qsv decoder from ffmpeg to intel media sdk sample_decode. There is pretty big speed gap. I wonder whether I did sth. wrong or there are really some problems with ffmpeg's implementation..
The test video was captured from a 3MP(2048x1536) camera. The commands I used: - ffmpeg -c:v h264_qsv -async_depth 10 -i test.h264 -c:v rawvideo -f null /dev/null - sample_decode h264 -i test.h264 Both uses 100% cpu (a full core). ffmpeg got 170FPS. sample_decode got 370FPS. I haven't got time debugging into this. Sending this out to see whether you guys might have sth. in mind.. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
