Carl, sorry to butt in, but you mentioned earlier: "I was under the impression that lavf/lavc support recovery points very well (even in slightly broken streams), ie that you (as a user) can choose if you only want to seek to a recovery point (slower, done by ffplay) or to some frame no matter if it is a recovery point or not (faster, this is what MPlayer does)."
Just out interest how does one force seeking only to recovery points in lavf/lavc programmatically ? I have never been able to achieve this, in fact I have had to implement my own demuxers just for this purpose.
