#4046: DVB subtitles not detected in TS file -------------------------------------+------------------------------------- Reporter: | Type: defect Underground78 | Priority: normal Status: new | Version: git- Component: | master undetermined | Blocked By: Keywords: | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: [http://www.datafilehost.com/d/63febb26 This sample] has two DVB subtitle tracks but ffmpeg doesn't detect them unless you skip the beginning of the file with `-skip_initial_bytes 61289`. I tried changing `-probesize` and `-analyseduration` without any luck.
