Thanks for the answer. I did not try yet, but I do not think this will 
fix my problem: the packet pts and dts (generated by libavformat) are 
currently ok (in fact, I am now using such timestamps instead of the 
codec's one); it's the avframe pts (generated by the decoder) which is 
wrong...
Since AVFMT_FLAG_GENPTS is a "format flag", I do not think it can help 
in this case (it will change the way libavformat generates the pts, but 
I do not think it can change libavcodec's behaviour).
