Fixes pts generation.

Setting frame_size in dolby_e_init() or get_audio_frame_duration()
can result in a bad duration value for the first packet if dolby_e is
muxed in a container having a different sample_rate (ex:
container @48KHz, DolbyE @44.8KHz).
Maybe adding a parser to dolby_e would fix the issue and makes it
possible to set frame_size at decoder init which seems the best place.
