I agree with this in principle but i think the merging code should be in a
This maybe could also be used by matroska, but note, iam not completely sure

parser needs to know that the next will have a different pts. This could
lead to unacceptable latency for matroska+avparser when there is some time
between subtitle packets. But maybe iam missing something ...
