GStreamer | gst-plugins-good | Ver: 0.10.5
Summary: v4l2src cannot select video inputs (channels)
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: thomas.bauer at hauptversammlung.at
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: 2.15/2.16
GNOME milestone: Unspecified
Please describe the problem:
you commented out a part of 'gstv4l2object.c'. This made it impossible to
select the proper v4l2 videosource ( Tuner, Composite1 or S-Video ) from my usb
videograbber (WinTV USB2) because you made the 'channel property inaccessible.
I uncommented the affected lines and it worked like a charm.
/* FIXME norm, channel, frequency are part of the tuner interface, so they
should be removed from the properties
g_object_class_install_property (gobject_class, PROP_NORM,
g_param_spec_string ("norm", "Norm", "Standard norm to use",
g_object_class_install_property (gobject_class, PROP_CHANNEL,
g_param_spec_string ("channel", "Channel",
"Input/output channel to switch to", DEFAULT_PROP_CHANNEL,
g_object_class_install_property (gobject_class, PROP_FREQUENCY,
g_param_spec_ulong ("frequency", "Frequency",
"Frequency to tune to (in Hz)", 0, G_MAXULONG,
Steps to reproduce:
1. connect v4l2 device with more than one video sources (e.g. WinTV USB2)
2. do something like e.g.: 'gst-launch v4l2src channel=S-Video ! xvimagesink'
3. watch for the error message
WARNING: erroneous pipeline: no property "channel" in element "v4l2src0"
have the video playing in a window
Does this happen every time?
after uncommenting the affected code it works again
