Re: [Vxl-users] decoding DV files using VXL & FFMPEG

[Matt L. <mat...@gm...>]

Vish,

  FFMPEG support in vidl is a fairly new addition to VXL.  It has not
been thoroughly tested.  The seek warning probably relates to a bug in
the way seeking is done in the vidl_ffmpeg_codec.  However, I have
seen this warning with some videos, but the video still loads fine.  A
first step might be to check that FFMPEG will play the video (open it
with the ffplay program that comes with ffmpeg).  If it does play
there is probably a bug in vidl.  You can try the CVS version of VXL,
I believe the was a recent bug fix in vidl_ffmpeg_codec, but I don't
know if it addresses your problem.

  We are currently in the process of redesigning the video library
from the ground up.  The new library is in contrib/brl/bbas/vidl2.=20
You could also try using this, though it's likely you might encounter
the same bug.  We will continue to develop and debug vidl2 and the
current vidl library in core is likely to become depreciated sometime
soon.
