Subject: avformat/mpegts: Continue parsing PMTs during duration estimation
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=db0471c40f0fb30355c07cca5fe7317ab6778b5a;hp=a7f25979dd568f4f7253ebb3e30f802c7009fbaa;p=ffmpeg

avformat/mpegts: Continue parsing PMTs during duration estimation

This way if we by chance run into a valid PMT we have a more complete
set of streams, also do not reset streams in case we run into a worse
PMT

Fixes Ticket4046

alternatively Ticket4046 could be closed as invalid or wontfix as it contains
some PMTs which lack the 2 subtitle streams
