Package: v4l2loopback-dkms
Version: 0.9.1-2
Severity: normal
I'm trying to intercept a video stream from a webcam and crop it a bit
before passing it on for further processing. I found v4l2loopback,
which sounds like it's exactly what I'm looking for. However, I get
crashes as soon as I try to insert processing in the pipeline.
The following works:
,----
| $ gst-launch-1.0 v4l2src device=/dev/video0 ! v4l2sink device=/dev/video1
`----
(Works as in I'm able to see the video with "gst-launch-1.0 v4l2src
device=/dev/video1 ! xvimagesink")
The following, however, doesn't (I added some debugging):
,----
| $ gst-launch-1.0 v4l2src device=/dev/video0 ! videocrop left=160 ! v4l2sink
device=/dev/video1
| Setting pipeline to PAUSED ...
| Pipeline is live and does not need PREROLL ...
| Setting pipeline to PLAYING ...

I'm pretty sure the problem lies with v4l2loopback, since replacing
the v4l2sink with a simple xvimagesink in both pipelines gives me the
unaltered stream in the first case and a cropped one in the second case.
This takes out much of the value of v4l2loopback, if I can only resend
video as-is :-)
Thanks,
Roland.
