tsdemux failure with Audio and Video

[Rand Graham]

Hello,

I am able to demux the video or audio from a transport stream file separately. However, when I try to demux both audio and video I get a no more pads error. I have tried this without naming the pads based on a previous suggestion. Can someone explain the no more pads error and why the pipeline fails? (I have noticed that the no more pads error also is output when giving the incorrect name of a pad.)

Here is the output of the failed pipe line:
