mpegts over udp file that allows to reproduce the problem described in this bug

Hi,

On attempting to play the attached espn_small.pcap stream, the pipeline is
blocked in PREROLL step when indicating the audio PID.

The pcap file contains a mepgts stream with VIDEO: pid 0x801 (2049) codec mpeg2
and AUDIO: pid 0x802 (2050) codec AC3.

 * Steps to reproduce:

gst-launch-0.10 filesrc location=espn_small.pcap ! pcapparse ! mpegtsparse !
mpegtsdemux es-pids="0x802" name=d ! queue ! mpegvideoparse ! mpeg2dec !
xvimagesink  d. ! queue ! ac3parse ! a52dec ! audioconvert ! alsasink

 * Actual result:

Piepline blocked in PREROLL step


 * Aother infos:

If I set es-pids="0x801" then the video AND the audio are played. Why is audio
played so ?
