Steps to reproduce:
I try to playback a mpeg file with ac-3 audio. I try the following command:
gst-launch-0.10 filesrc location=/tmp/ac3.mpg ! dvddemux .current_video {deque
! mpeg2dec ! ffmpegcolorspace ! videoscale ! xvimagesink}
dvddemux0.current_audio {a52dec ! audioconvert ! osssink}
some information is listed:
Setting pipeline to PAUSED ...
No accelerated IMDCT transform found
Pipeline is PREROLLING ...

<Here, this command will be freezed, i have to CTRL-C to continue>
But, while i don't link audio or video branch, like thus
gst-launch-0.10 filesrc location=/tmp/ac3.mpg ! dvddemux .current_video {deque
! mpeg2dec ! ffmpegcolorspace ! videoscale ! xvimagesink}

gst-launch-0.10 filesrc location=/tmp/ac3.mpg ! dvddemux .current_audio {a52dec
! audioconvert ! osssink}

It is work normally. i can see video pictures or listen correct audio.
Anyone can tell me why and how to solve?
