[FFmpeg-devel] [PATCH 0/6] avcodec: Vorbis encoder improvements

[Tyler Jones]

Please see the following patches.

The first two patches are identical to my latest pending changes sent to the
mailing list on July 28. Changelogs are included regardless. The clipping 
avoidance patch should remove most clicking that had been noticed by
atomnuker in previous versions.

Thanks in advance.
