VLC .mkv integrated subtitles error

Sun Apr 03, 2016 10:40 am

Hi... When I try to play some mkv video with integrated subtitles ... when I start that video in VLC it shows this message:

Unidentified codec:
VLC could not identify the audio or video codec

Both Czech and English language work and when I try to turn on Czech or English subtitles manually that message pop again and subtitles don't showing. It's problem only with matroska .mkv (tested on more than 30 videos) and only with integrated subtitles (not in that when you choose subtitles from file on harddrive). I watched these videos without problem before on Windows 8 10, Bodhi Linux, Ubuntu 15.10, Kubuntu 15.10 and Lubuntu 15.10. I know that VLC uses own codecs.

Thanks... and I know I have many problems what cost you time but I hope it helps to repair bugs.

Same here.
VLC states that subtitles within mkv have no codecs to be processed with.
Everything works but the displaying of integrated subtitles.
Does not happen with external subtitles.

Package issue?

Package issue. Any sample (free) files around that I can test this on to fix it?

Ikey i have the problem too with VLC on solus 1.1 up to date.

You can test with test5.mkv (Matroska Validation Suite) and you'll see errors with subtitles : http://download.wavetlan.com/SVV/Media/ ... tp-mkv.htm

Thanks for your amazing work !

Install mkvtoolnix, it has a mkvinfo app that tells you about the file, codecs, etc.

Ah cheers Justin. FWIW Totem works with the subtitles, and I rebuilt VLC with Kate support, but no win yet..

I use MKVTookNix to to mux an mp4 video file and VTT subtitles file. I had the same problem. Using VLC to playback, it has the same error. But when I play the subtitles as an external file, I have no problem.

Is the problem with MKVToolNix or VLC? Or is it some settings that I've missed.

I noticed that for subtitles that work, it's codec is S_TEXT/UTF8. For the VTT subtitles, it's S_TEXT/WEBVTT.

Any workaround?

Still intend to have a rebuilt VLC land in the next couple of days to address this, it's "in progress"

Hi, I am receiving this error from the latest version of VLC (2.2.4).
Just wondering if there has been any progress and to say that I can provide a .mkv file where the error occurs if you need to reproduce it.
