           Summary: decklinksrc fails when using both video and audio
    Classification: Platform
           Product: GStreamer

        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad

The following works:


gst-launch-1.0 decklinksrc mode=11 connection=0 audio-input=3 !
video/x-raw,format=UYVY,width=1920,height=1080,framerate=30000/1001,interlace-mode=interleaved
! queue ! v4l2sink device=/dev/video0 sync=false 

The following also works:

gst-launch-1.0 decklinksrc mode=11 connection=0 audio-input=3 !
audio/x-raw,format=S16LE,channels=2,rate=48000,layout=interleaved ! queue !
audioconvert ! audio/x-raw,format=F32LE ! jackaudiosink connect=0
client-name="Video Capture SRC"


The following does NOT work:

gst-launch-1.0 decklinksrc mode=11 connection=0 audio-input=3 name=SRC SRC. !
video/x-raw,format=UYVY,width=1920,height=1080,framerate=30000/1001,interlace-mode=interleaved
! queue ! v4l2sink device=/dev/video0 sync=false SRC. !
audio/x-raw,format=S16LE,channels=2,rate=48000,layout=interleaved ! queue !
audioconvert ! audio/x-raw,format=F32LE ! jackaudiosink connect=0
client-name="Video Capture SRC"

And the error message is fantastically benign. Cannot figure out why it fails.
I'm uploading a debug output.
