AW: [gst-devel] simple raw video RTP -- still no joy

[Jan Rübel]

Dear Wim,

Thanks for the quick reply. 

What I do not understand: why does it say video/x-raw-rgb in the caps (see result of gst-inspect below)?
Does the code in gstrtpvrawdepay.c referring to "video/x-raw-rgb" or "RGBA" have no effect?

Best regards,
Jan
