This patch made audio encoding extremely slow. time ./ffmpeg -i INPUT.wav -c:a tta -f null - Before size=N/A time=00:00:22.98 bitrate=N/A speed= 373x video:0kB audio:1272kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown real 0m0.089s user 0m0.000s sys 0m0.000s After size=N/A time=00:00:22.98 bitrate=N/A speed=2.29x video:0kB audio:1272kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown real 0m10.087s user 0m0.015s sys 0m0.000s CPU usage for the latter is almost zero during the entire 10 seconds. And it can be reproduced with pretty much any encoder. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
