[Libav-user] FFmpeg x264 settings for zero-delay encoding?

[Aleksey Shubin]

There is "preset" and "tune" options in ffmpeg, you can set them that way:

#include "opt.h"

av_opt_set(codecContex->priv_data, "preset", "ultrafast", 0);
av_opt_set(codecContex->priv_data, "tune", "zerolatency", 0);

where codecContex is AVCodecContext.

For other x264 options that isn't presented in ffmpeg you could use
"x264opts" option:

av_opt_set(codecContex->priv_data, "x264opts",
"no-mbtree:sliced-threads:sync-lookahead=0", 0);
