Actually, since I did address all the comments either by changing the 
code according to them (most) or argumenting why it is needed to do it 
that way (one or two), I didn't feel there are open points. I didn't get 
any comments on state saving/restore. Since I didn't hear from Baptiste 
for a month, I assumed, he is OK with the changes made (as per FFmpeg 
development policy point #11).

The comments from Michael regarding timestamp handling have been 
integrated as well in the code.

So what are the open points in your opinion? What still needs to be 
reviewed? Possibly the state saving/restore, but otherwise I think the 
whole stuff was reviewed sufficiently. BTW, what useless casts did you mean?

Since the new seeking code is completely contained separately of format 
handlers, I propose instead of the full revert the following: I'll put 
an #ifdef in mpegts.c, which disables the new seeking and uses the old 
stuff per default (as per FFmpeg development policy point #2). I can do 
it today evening. What do you think?

Thanks & regards,
