For some reason VLC fails to play a video when I add a .srt or .sub subtitle to the folder containing the video.

I use VLC to capture the video (h264 and mpeg4) and audio (mp3, aac) from a streaming server and save it to .mkv or .mp4 container.

Without the subtitle the video plays fine.

I'm using the standard module to capture video:

Code: Select all

--sout="#standard{access=file,access_audio=file,mux=ts,mux_audio=ts,dst=%s}"

When I try to play the MKV or MP4 with SRT or SUB I get the following error:

Code: Select all

[0x9dc08bc] ts demux error: MPEG-4 descriptor not found
[0x9dc043c] main demux error: option sub-original-fps does not exist

As far as I have tried the problem persists on different VLC releases (1.1.7, 1.1,2, 1. 0.6).
I'm using linux but it doesn't work in windows either.

Does anybody have a solution?

When I change the muxer to 'ps' then the video will start to play but no subtitle.
The following is displayed when opening the video:

Code: Select all

[0xb4e518dc] main demux error: option sub-original-fps does not exist
[0x9cc6ae4] xcb_xv generic error: no available XVideo adaptor
header damaged

I tried to open the MKV with mkvmerge and add a subtitle stream but It only recognizes the audio stream, so the outputfile has no video stream.

I don't know about srt files but I had problems with VLC auto-detecting my idx/sub file combo. Another post in the forum suggested changing the subtitle encoding. I changed from Windows (1252-something) to Universal (UTF-8) and my videos all play with subtitles now.

Hope this helps,
Mark

I'll have to see whether the encoding makes any difference.
However, when I use OGG as container format with Theora and Vorbis codecs the subtitles show up nicely, although there's something wrong with VLC reporting the duration of the video file.
