Dynamic change of bit_rate for Video

Post by Vicul »

I use ffmpeg codes in my C++ app and would like to control the bit_rate parameter for VIDEO there. I tried to change its value in work (via ost->st->codec->bit_rate), but ffmpeg did not wish to change it.
Perhaps anybody knows how to make it?

Any ideas?

I know x264 allows for "dynamic reconfiguring of the bitrate" but I'm unsure if this is plugged into ffmpeg...suggest asking libav-user or ffmpeg-user mailing lists...
