[gst-devel] connecting gdkpixbufsink and xvimagesink to a tee

[sudarshan bisht]

Hi,

xvimagesink supports both yuv and rgb format , but gdkpixbufsink supports
only rgb  format  So while "caps negotiations" yuv format has been aggreed
between videotestsrc and xvimagesink , but that is not supported by
gdkpixbufsink.  But to do your job done you can use ffmpegcolorspace between
queue and gdkpixbufsink .
