[FFmpeg-user] ffmpeg adn *EXPERIMENTAL* x262/x264

[JULIAN GARDNER]

Just wondering if anybody had gotten ffmpeg and libx262 to work in either mode x262/x264?

im using this command line
./ffmpeg -i ../testStreams/Pil.avi -preset faster -vcodec libx264 -x264opts bitrate=1000:vbv-bufsize=2000 -s 720x576 -acodec mp2 -y -f mpegts a.ts

and get this

Video encoding failed

Now when using mpeg2 i get the same error as long as i add dc=10:mpeg2 tp the x264opts option.

I was hoping this would be a drop in replacement as ffmpeg's mpeg2 encoder is a little lacking.
