Hi Chuck,
thanks for getting back in touch. I've attached the output of the
command with the debug environment you've recommended.
The line before one of the errors are like this:
INFO GST_ELEMENT_PADS gstutils.c:1614:gst_element_link_pads_full:
trying to link element audioconvert3:(any) to element i:sink_0
INFO GST_ELEMENT_PADS
gstelement.c:960:gst_element_get_static_pad: no such pad 'sink_0' in
element "i"
INFO default
gstutils.c:1944:gst_element_link_pads_filtered: Could not link pads:
audioconvert3:(null) - i:sink_0
ERROR GST_PIPELINE grammar.tab.c:713:gst_parse_perform_link:
could not link audioconvert3 to i
What seems to be the problem is that, according to the documentation
there should be a sink_%u in interleave with a corresponding src_%u in
deinterleave. The debug info spits out the following:
GST_PLUGIN_LOADING gstplugin.c:857:gst_plugin_load_file: plugin
"C:\Program Files
(x86)\OSSBuild\GStreamer\v0.10.7\lib\gstreamer-0.10\libgstinterleave.dll" loaded
INFO GST_ELEMENT_FACTORY
gstelementfactory.c:369:gst_element_factory_create: creating element
"deinterleave"
INFO GST_ELEMENT_PADS
gstelement.c:716:gst_element_add_pad:<GstDeinterleave at 0211A0B8> adding
pad 'sink'
INFO GST_ELEMENT_FACTORY
gstelementfactory.c:369:gst_element_factory_create: creating element
"interleave"
INFO GST_ELEMENT_PADS
gstelement.c:716:gst_element_add_pad:<GstInterleave at 021460B8> adding pad
'src'
Does this mean my plug is defective in some way and I should try a
different version/build?
One of the other warnings that appears to be omnious is:
INFO GST_ELEMENT_PADS
gstelement.c:960:gst_element_get_static_pad: no such pad 'src%d' in
element "decodebin0"
Though I'm not sure whether that's a side effect of the above or not.
Any ideas welcome..
Thanks,
Wouter
