[vlc] Broken video with rawdv and firewire connection

[John Roberts]

Please help - I've been trying to debug this for days... And I'm at the end
of my rope.

I've gone through every mailing list and google'd till the cows have come
home and I can't figure out what the issue is.

I have tried VLC v0.8.5 and the most recent SVN version (6/2/06) and both
result in very badly broken video feeds over firewire.  I'm able to do a
dvgrab without a problem and then playback the feed using VLC and all looks
great.  So - I believe the firewire "connection" is fine since I'm able to
capture and later play back the video.

I also had a terrible time trying to get VLC to auto-detect which demuxer to
use - it was always complaining about "garbage" on the firewire input.  It
wasn't until I forced it to use the "rawdv" demuxer that I was able to get
video at all.  But the video is broken, stutters and pauses badly.

I've tried installing the most recent "stable" and CVS/SVN versions of ogg,
vorbis, libdv, and others - but all result in the same broken feed.

The system is a Gentoo 2006.0 build running with a Pentium D processor and
2G of memory - so I don't believe there is a resource issue of any kind.

The camera is a Canon GL2 running without a tape and feeding the DV content
via firewire into the VLC server.

If anyone has any idea - I'd MUCH appreciate it!!!  I've uploaded the video
file into the /incoming directory of the videolan ftp site - but it was the
dvgrab output which I believe defaults to an avi and not the raw 1394
capture.
