Stop position ignored

[flobadob]

I cannot get my graph to recognise the stop position when calling IMediaSeeking::SetPositions. I'm grabbing a small video clip so the stop position is important. The start position works ok. Graph looks like...

async reader -> mp4 demuxer -> mp4 muxer -> file writer.

I build the graph, set the reference clock to null, call SetPositions, run the graph, waitforcompletion. The call to setpositions returns S_OK. It's all working fine apart from the output file being too long - starting at the correct place but continuing right to the end of the original file.

I understand that the demuxer is responsible for honouring the stop position. Does the Elecard mp4 demuxer honour the stop position?

Hello flobadob!

What values do you set for the parameters when you call the SetPosition function?
