Just because a device supports a certain resolution in mode doesn't mean that it supports it in all modes. Use v4l2-ctl to 'talk' to the device and see exactly what it supports. Post your command/script that is trying to access the device. You can also enter 'export GST_DEBUG=v4l2src:4' to get a lot of debugging tracing to see what is failing. If you haven't, read this: <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/index.html">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/index.html</a> and this: <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html</a> for good debugging info. <div class="gmail_quote">On Sun, Feb 17, 2013 at 10:00 AM, Mex87 <<a href="mailto:nikmess@hotmail.it" target="_blank">nikmess@hotmail.it</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hello everyone, I am now a developer who will use Gstreamer. I have a problem with the plug-in "v4l2src" in practice I would like to capture video using the Pinnacle Dazzle DVC 100, everything works but not perfectly, in practice the maximum video resolution that I can get is 592x576 when the device supports 720x576. I set Tuner PAL device and channel Composite1. I am using ubuntu 12.04.1 with GStreamer 0.10 I would also add that they are without experience, so it might be my fault, but I do not know how to proceed.
