<html> <head> <meta content="text/html; charset=ISO-8859-1" http-equiv="Content-Type"> </head> <body text="#000000" bgcolor="#FFFFFF"> 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@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@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..

So, you need to crank up the logging to see what is not happy, where the link process fails. The logging during setup can be quite verbose, but you need to get some things. So, try export GST_DEBUG=*:3, GST_ELEMENT:5 see what you get and go from there. Please report your findings a) for additional comment/help if needed, b) as a guide for others. </div> <div class="gmail_extra"> <div class="gmail_quote">On Wed, May 14, 2014 at 12:36 PM, Wouter Klouwen <<a moz-do-not-send="true" href="mailto:dublet@acm.org" target="_blank">dublet@acm.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello all, I'd like to use gstreamer to play some videos while directing the audio output to specific channels. My computer has two sets of stereo outputs (LR & rear LR) and I'd like to be able to direct which of these receives the output of playback. As far as I understand it, the interleave & deinterleave plugins should be able to do what I want, so to get my head around how this could work, I tried the example in the documentation*: $ gst-launch filesrc location=file.mp3 ! decodebin ! audioconvert ! "audio/x-raw,channels=2" ! deinterleave name=d interleave name=i ! audioconvert ! wavenc ! filesink location=test.wav d.src_0 ! queue ! audioconvert ! i.sink_1 d.src_1 ! queue ! audioconvert ! i.sink_0 But when I execute this with an mp3 file, I get this output: 0:00:00.076005000 5324 00528D00 ERROR GST_PIPELINE grammar.tab.c:71 3:gst_parse_perform_link: could not link audioconvert3 to i 0:00:00.081005000 5324 00528D00 ERROR GST_PIPELINE grammar.tab.c:71 3:gst_parse_perform_link: could not link audioconvert0 to d 0:00:00.086005000 5324 00528D00 ERROR GST_PIPELINE grammar.tab.c:71 3:gst_parse_perform_link: could not link audioconvert2 to i WARNING: erroneous pipeline: could not link audioconvert3 to i This is using gstreamer 0.10.
