#5796 new defect

ffmpeg recognises but does not process subtitle stream

Reported by: keynet Owned by:
Priority: normal Component: undetermined
Version: git-master Keywords: dvbsub mpegts
Cc: Blocked By:

Analyzed by developer: no

Description

MPEGTS stream recorded from TV by current VDR (2.2)
Trying to transcode to H264, but same happens if just doing a simple stream copy of all streams
How to reproduce:

ffmpeg -v 9 -loglevel 99 -i sample.ts -c:s copy -c:v copy -c:a copy -map 0 out.ts

ffmpeg version 3.0.2-80.1 (SLES11 from Packman) built on 31 May 2016

ffmpeg reports:
video:3675kB audio:995kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 10.355034% (complete log attached)

There are a number of DVB subtitles present in this sample of the recording, none appear in the output stream. Muxer reports 12 subs packets of 168 bytes total, much smaller than they should actually be.

5M sample attached under this ticket#

Stream plays with correct subtitles in VLC and MPC-HC, but not in ffplay or Kodi. This is an unusual issue as hundreds of files have been processed correctly, this is the 0.1% that strangely fails
