[Ffmpeg-devel] 4.8 and CVS capture code diffs

[Pete Foster]

Hi list

What changed between 4.8 and the current CVS with regards to capture
hardware?

I have a generic el-cheapo Bt878 capture card that works fine under 4.8
(when compiled with gcc32), but doesn't work in the current CVS.  All I get
is the following:

FFmpeg version CVS, Copyright (c) 2000-2004 Fabrice Bellard
  configuration:
  libavutil version: 49.0.0
  libavcodec version: 51.2.0
  libavformat version: 50.2.1
  built on Feb 10 2006 23:17:29, gcc: 4.0.2 20051125 (Red Hat 4.0.2-8)
File 'test.mpg' already exists. Overwrite ? [y/N] y
Could not find video grab device

I've lived with this up until now because 4.8 has worked for me.  But now I
want to make use of the watermark vhook.

My coding isn't up to the task of examing the source and working out what's
wrong.  :o(

Even pointers to where to look in code would be appreciated.

Regards

(lspci -v and dmesg under sig)
