[FFmpeg-devel] Bug? FFmpeg 0.8.4, LGPL, libvpx only : Additional information: g_lag_in_frames out of range [..0

[Fabrizio Milo aka misto]

I compiled a version of ffmpeg using only libvpx, libogg and libtheora
on Centos 6.

I get:
[libvpx @ 0x16e5040] Failed to initialize encoder: Invalid parameter
[libvpx @ 0x16e5040]   Additional information: g_lag_in_frames out of
range [..0]
even with the default video preset set.

Any Idea what is wrong ? Is it a Bug ?

Here is the complete output:
