gst_xvimagesink_get_xv_support: Generated the following caps: video/x-raw-yuv,
format=(fourcc)YUY2, width=(int)[ 1, 4096 ], height=(int)[ 1, 4096 ],
framerate=(fraction)[ 0/1, 2147483647/1 ]; video/x-raw-yuv,
format=(fourcc)YV12, width=(int)[ 1, 4096 ], height=(int)[ 1, 4096 ],
framerate=(fraction)[ 0/1, 2147483647/1 ]; video/x-raw-yuv,
format=(fourcc)I420, width=(int)[ 1, 4096 ], height=(int)[ 1, 4096 ],
framerate=(fraction)[ 0/1, 2147483647/1 ]; video/x-raw-yuv,
format=(fourcc)UYVY, width=(int)[ 1, 4096 ], height=(int)[ 1, 4096 ],
framerate=(fraction)[ 0/1, 2147483647/1 ]

=> no RGB support in xvimagesink in your case.


(In reply to comment #10)
> The same pipeline built in python yields the attached messages.
> They show:
> All elements successfully reach state READY

Yes.

> 1) filter reaches the state PAUSED (or is reaching)

Yes, it reaches PAUSED state (this doesn't mean anything, this happens before
data flow has started yet).

> 2) ffmpegcolorspace, trying to go on PAUSED state yields the error: "The stream is in the wrong format"

No. ffmpegcolorspace is already in PAUSED state at that point. And it is the
source that posts this error message because it can't figure out compatible
caps (because you force the ffmpegcolorspace-xvimagesink link to a format that
is not actually supported).


I'm going to close this as NOTABUG now.

Please post to the mailing list or stop by our IRC channel on freenode if you
have further questions related to this. You might also have a look at the
design docs in gstreamer/docs/design, linked to from our homepage.
