You can try to build our master branch, which already ships ffmpeg 2.7.x - i think that's rather an ffmpeg regression.

Which ffmpeg version is your vlc compiled against?

[fxeon]

You're way out of my league there !
Pacman says it's ffmpeg 1:2.7.2-2 and vlc 2.2.1-6

[fritsch]

okay. Kodi stable is shipped with 2.6.3 - while our master branch already uses 2.7.2

Kodi 15.1 will have 2.6.4

In the meantime I filed a bug at handbrake. Thank you and don't worry I'll just repack the offending files with mkvmerge.

[SuperBFG7]

Any answer on the handbrake bug?
And did repacking the files help?

I'm experiencing the same problem recently: mkv files with mp3 audio encoded with handbrake.

The files worked in kodi 13.x and 14.x but not anymore since 15.x
I'm also on archlinuxarm (RPi2) and suspect fritsch might be right: it's hard to believe that kodi 15 dropped support for these files and GCC5.2 breaking ffmpeg is much more likely.

The only thing that confuses me: I tried to open the files with vlc on my ipad and had the same issue (no audio)...

[fxeon]

Here's the answer i got:
mp3s in mkv don't play in kodi
Repacking the files with mkvmerge works a treat.

[SuperBFG7]

thanks, I'll try repacking then.

[fxeon]

It only takes seconds for each file using mkvmerge, didn't try to do a batch job though

I had the same problem with mkv-files converted with HandBrake on ArchLinux

As stated above, repacking the files with mkvmerge works nice.

just type in:

mkvmerge -o Repacked.mkv MyVideo.mkv

this will repack the file "MyVideo.mkv" to the repaired version "Repacked.mkv", which plays nice in 15.1 using openELEC 5.95.4

repacking just takes seconds, so my batch-command was done in 3 minutes, repacking all the good stuff I captured from TV over the years... (yes, in Germany we do have really good valued tv for children)

A batch command could look like this one:

Code:

for i in *.mkv; do mkvmerge -o "$i".mkv "$i"; mv "$i" "$i".old; mv "$i".mkv "$i";done

Any differences in mediainfo after mkvmerge?

[produnis]

Mediainfo in VLC is the same in both files..
If you want to test/check on your own, here is a 38mb file (5min), that I converted from a DVB-S stream using HandBrake on ArchLinux:

https://www.dropbox.com/s/vi5hcigi1pombq...e.mkv?dl=0

This file has problems in Kodi 15, but plays nice in Kodi 14 (and any other player).

If you do a "mkvmerge" on that file, it will play nice in Kodi 15, too

Code:

diff DerTagAnDemLouisGefressenWurde_info.txt DerTagAnDemLouisGefressenWurde_info_repacked.txt

on that file's mediainfo gives

Is the mp3 still one channel after the merge, that was my question. Currently on holidays cannot test anything myself, therefore the dumb question.

So please post the two mediainfo outputs.

[fxeon]

We answered nearly at the same time :-D

[fritsch]

Numbers of frames and numbers of bytes are completely different. Also the version index looks broken in the original.

Edit: Bitrate and Tag seem changed ... also post both outputs, the diff is hard to read. I seems in the original some meta stuff is missing, but that's not mandatory.
