            Bug ID: 774507
           Summary: splitmuxsink: pad request fails for flvmux
    Classification: Platform
           Product: GStreamer
           Version: 1.10.0
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-good
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: vinodkesti at yahoo.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

All,

Splitmuxsink is not compatible with flvmux. splitmuxsink is not able to request
pad due to incompatible pad templates.

Below pipeline fails.
gst-launch-1.0 videotestsrc is-live=1 ! x264enc ! h264parse ! splitmuxsink
muxer=flvmux location=./test.flv

(gst-launch-1.0:25551): GStreamer-CRITICAL **: gst_element_request_pad:
assertion 'templ != NULL' failed
0:00:00.034612942 25551      0x2675100 ERROR           GST_PIPELINE
grammar.y:728:gst_parse_perform_link: could not link h264parse0 to
splitmuxsink0

splitmuxsink requests pad from element using pad template like "video_%u",
"audio_%u" and "sink_%d". This is true for most of the muxers.

But splitmuxsink not able to request pad to flvmux as flvmux has "audio" and
"video" as pad templates.

Regards,
Vinod
