Hi simon

  I've performed a SVN and CVS yestarday at 10am (gmt -3:00), I think
at that time the svn is not yet updated.
  For my cam the Directshow is working fine, only found an exception
in 'hot-switching' resolution.
  I tested ptlib with Logitech Quickcam Pro 4000, 5000 and Microsoft
VX1000. The two fisrt ones accept capture native in BGR24, VYVU and
i420 (YUV420P) for resolutions from subQVGA at 30, QCIF at 30, CIF at 30,
QVGA at 30 and VGA at 16

  I agree the behaviour is in color conversions. I have the same
problems when grabbing the video from PWLib to Java (the old PWLib
that don't have dshow support), for Java the color must be fized or
converted to BGR32 too (plus little-endian to big-endian)

  The strange is the problem is only on openmcu and simpleplus
applications, I used and tested all color modes and conversions on
VidTest app and all passed.

  I'll download the new trunk.

Regards,
Eng. Marcos F. Jardini


PS.:  I like the Monogram's Blog (http://blog.monogram.sk/janos/) for
hints on DShow programming, the guys there have a nice work on
ffmpeg/x264 support on dshow filters.
