            Bug ID: 759807
           Summary: Cannot use GST_STREAM_FLAG_SPARSE with mpegtsmux
    Classification: Platform
           Product: GStreamer
           Version: 1.6.2
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: alexvasiljev at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Setting GST_STREAM_FLAG_SPARSE to one of inputs of mpegtsmux stops both input
streams.

May be the cause is in libs/gst/base/gstcollectpads.c

Here is a patch. With this patch GST_STREAM_FLAG_SPARSE works as expected.
