Seek requests to multiple sinks

[Mohammad Afaneh]

Wim, thanks for your answer. 

I was thinking of doing exactly that, filtering the duplicate requests and only handling one based on the sequence number. However I noticed that there was an API that allows changing the sequence number so I wasn't sure how reliable it would be to do this in the event that someone/something changes the seq number without the demux knowing. 

This is being done in a custom bin, not playbin2, but maybe a good solution would be to follow playbin2's technique and only send it to one sink.

Is there a disadvantage to sending the seek specifically to the element that I know should handle it (instead of going through the sink(s))? In my pipeline's case it's always the source which handles the seeks.

Thanks,
Mohammad

For example, a pipeline with a demux and an audio path and a video one, you will get two seek requests at the demux (at least that's what I have seen happen ), how do you handle these two requests?
