With shame I have to tell it does work, when you maximize the xawtv window.
:-s The window size seems to effect the video stream directly. If the window
is smaller then the resolution, the image gets all messed. The same for pure
data, if I add the dimension the video streams comes out.
BUT the colors are messed up. It seems green is ok, but blue and red are
switched. I have tried the colorspace settings, they seem to have effect in
the way that the colors do change in brightness/hue, but red and blue are
still switched in both YUV and RGBA colorspaces. The gray colorspace has no
issues.
I also tried correcting the stream with filters/converters in PD like
pix_rgba, but without success. Any suggestions?
