            Bug ID: 747457
           Summary: ts-streaming from file to vlc doesn't recover on
                    unaligned ts
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-rtsp-server
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: fraxinas at opendreambox.org
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

i've observed that i couldn't stream certain ts files from gst-rtsp-server to
vlc (gstreamer as a client works) so i digged a bit and found out that the
trigger for the issue were random bytes before the first ts packet

this is easily reproducable:
just prepend a few bytes before a valid, working ts file
printf "blafaselfoobar1234567890abcdefghijk" | cat - streamtest.ts >
streamtest-broken.ts

start gst-rtsp-server
test-launch "( filesrc location=streamtest-broken.ts ! tsparse
set-timestamps=true ! queue ! rtpmp2tpay name=pay0 pt=96 )"

playback with vlc
