Hello everyone,
I'd like to know if something's wrong with rate control in the CVS versions
I've been downloading from the last weeks. Specially when encoding with
H.264. The output generated has a very different bitrate than the one I ask
for.
I'm compiling CVS sources in Windows with mingw and this is an example of a
command-line I'm testing:
./ffmpeg -i video.avi -vcodec h264 -b 512 -acodec mp3 test.avi
While encoding FFMPEG reports bitrates of 3000 kbit/s, not 512 kbps. Mp3
bitrate is 64kbps.
Right now I'm testing with version 2005-12-01, and the same is happening
with MPEG4.
Regards,
Juan Jose
