[FFmpeg-devel] [PATCH] lavf/utils: Only adjust pkt->pts by st->first_dts if presentation is not delayed

[Tomas Härdin]

This is the result of half a day's worth of staring at
compute_pkt_fields().

The attached patch limits the scope of the first pts adjustment done by
update_initial_timestamps(). Only the WTV demuxer's behavior changed,
and that to the better; the FATE sample's first PTSes went from
-40000,40000,80000 to 0,40000,80000.

Passes make fate (after figuring out the lavfi tests need --enable-gpl)
