Rodger Combs 2b20290061 lavf/segment: fix crash when failing to open segment list This happens because segment_end() returns an error, so seg_write_packet never proceeds to segment_start(), and seg->avf->pb is never re-set, so we crash with a null pb when av_write_trailer flushes the packet queue. This doesn't seem to be clearly recoverable, so I'm just failing more gracefully. Repro: ffmpeg -i input.ts -f segment -c copy -segment_list /noaxx.m3u8 test-%05d.ts (assuming you don't have write access to /)		2017-01-23 05:44:49 -06:00
