                    : .�/}
    Classification: Platform
           Product: GStreamer

When recording a h.264 stream from a Logitech C920 camera, the stream seems to
at some point always fail with following message:

ERROR: from element
/GstPipeline:pipeline0/GstUvcH264Src:src/GstUvcH264MjpgDemux:uvch264mjpgdemux0:
Unknown auxiliary stream format : .�/}

The pipeline used is:

gst-launch -v -m uvch264_src auto-start=true initial-bitrate=5000000 name=src \
    mpegtsmux m2ts-mode=true name=mux ! filesink location=somefile.mts \
    src.vidsrc ! video/x-h264,width=1920,height=1080,framerate=30/1 ! queue !
h264parse ! mux. \
    src.vfsrc ! queue ! autovideosink \
    \
    alsasrc device="hw:1,0" ! voaacenc !  mux.

It probably is something weird coming from the camera, if the stream format
should be a FOURCC.

When I have more time, I'll try to make the aux_header.type switch in
gst_uvc_h264_mjpg_demux_chain to demote the situation to a warning to see if
the streams survives it. But it seems that for some reason it tears down the
whole source; may be also a buggy EOF or something from the camera.

The version of gst-plugins-bad is yesterday's 0.10 git
(61bebbd5144d06534491ac6f0746d6a4e7db07f7).
