Workaround buggy flv files (#2590).
Workaround buggy flv files (#2590).

 It seems that (a lot of?) flv files does not correctly set PTS,
so ignore them, with luck the decoder (avcodec) will recreate
them.
 It might break some valid files, so report any regression.

(It needs the AVCodecContext::ticks_per_frame change).
