Hi.

I'm trans-coding a MP4 media to H.264, and noticed that resulting files are
of same size or larger, as the source MP4 files.

It started to happen with the latest versions of FFMPEG (post 0.5), the
previous versions produced sizes 3-2 smaller.

The code does about the same as this command line - ffmpeg -i source.mp4
-vcodec libx264 -flags +loop target.mp4 - preserving same codec settings and
setting the loop flag.

Any idea what was changed, and what should I specify to get the new reduced
sizes?

Thanks in advance!


P.S. I posted this question to FFMPEG list before, as I thought that perhaps
there was some parameter change, and was answered that now libx264 presets
control the encoding behavior.

Question, is using presets required also when using libavcodec (and what
code turns them on then), or the usual codec settings still apply?
