[vlc-devel] Re: vlc on amd64 -- problems with mencoder's h264 and flash movie files

Hi Ben,

It's likely that the problem is indeed that VLC in sid uses a
cvs20050918 ffmpeg, though I haven't been tracking exactly when amd64
support was added to ffmpeg for flv or h264 and their changelogs are
uninformative.  I understand that the nightlies are built to be
compatible with sid's ffmpeg; this puts the onus on Debian to upgrade
ffmpeg. I've sent a bug report, though Sam may be reluctant to upgrade
as ffmpeg is a moving target and hasn't had an official release in a while.

I appreciate the help and will act on the assumption this is a build issue.
