<div dir="ltr">It seems like something in your caps must be causing the problem. First, look again at gst-inspect for each of your elements. I guess that the problem is with ffmpegcolorspace because the decoder should turn out I420. You could confirm this by setting GST_DEBUG=*2,GST_ELEMENT_PAD=4 and maybe something else (GST_ELEMENT=4?). It may be that, for the output you specify, ffmpegcolorspace can't use the decoder output or (more likely) just can't generate the requested output format period.<br>

I am trying to change the colorspace from video/x-raw-yuv to video/x-raw-rgb<br>
and output to xvimagesink (to begin with) and later to Snowmix. Currently I<br>
am getting the following error:<br>
