</div>What does "not working" mean? What are the symptoms? Are there any error<br>
messages being printed? Try enabling debug ("export GST_DEBUG=2" or 3<br>
or 4) and analysing the output for likely culprits.<br>

<br>
This is probably because videotestsrc is able to produce the format you<br>
are asking for with the first "video/x-ray-yuv" format specification,<br>
but your V4L source is not.<br>
<br>
What happens if you omit the entire first format specification:<br>
v4l2src ! ffmpegcolorspace ! etc<br>
That should allow ffmpegcolorspace to negotiate with v4l2src and choose<br>
a format that they both support.<br>
<br>
Cheers,<br>
