[gst-embedded] Syncing in TIDmaiVideoSink

[Andreas Auer]

Thank you for your reply and the interesting links. I wonder why I 
haven't found them with google.
BTW the decoder always buffers 1.5MB of data before decoding. But in the 
case you are getting the data from a file it cannot be noticed that the 
buffer is that big. I'll try to change this behavior after I have solved 
the synchronization issue.

You are right the video decoder doesn't declare its latency in a correct 
way. I found it yesterday while debugging and looking at the code. I 
think if the latency query is correct the large buffer shouldn't be a 
problem.

Increasing the bitrate isn't possible for me. I think the only way for 
me is to declare the correct latency. Curious that this haven't been 
done by TI itself.

Thanks for your help,
Andreas
