Hi all,
I'm trying to use my TerraTec Grabby (em2860 using em28xx module, tip v4l-dvb
sources). Everything works using mplayer.
Now I'd like to use the USB videograbber from gstreamer 0.10.24 but I get the
following error in dmesg:
em28xx #0: vidioc_s_fmt_vid_cap queue busy
And gstreamer tells me:
# gst-launch -v v4lsrc
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
ERROR: from element /GstPipeline:pipeline0/GstV4lSrc:v4lsrc0: No supported
formats found
Additional debug info:
gstbasesrc.c(2475): gst_base_src_default_negotiate ():
/GstPipeline:pipeline0/GstV4lSrc:v4lsrc0:
This element did not produce valid caps
ERROR: pipeline doesn't want to preroll.
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing pipeline ...
Does someone know what might be wrong?
Thanks in advance,
Dick
I'm not very familiar with gstreamer, but you should probably be using
v4l2src instead of v4lsrc, and you probably need to be specifying
the other parameters such as the video standard, capture width,
height, format, etc. The man page for gst-launch has some examples
you might want to look at (if you haven't already).
Cheers,
Devin
