FireTV wont play SOME movies

[bugmenot 1]

Hello,

emby wont play some movies. (4.5.2.0 on synology, direct play over nfs, FireTVStick4k)

If i remux the files 1:1 with mkvtoolnix to new file it works.

I find out that the creater used old versions on mkvmerge and libmatroska.

• mkvmerge v3.4.0 ('Rapunzel') built on May 15 2010 09:38:20
• libebml v0.8.0 + libmatroska v0.9.0

After remux

• mkvmerge v51.0.0 ('I Wish') 64-bit
• libebml v1.4.0 + libmatroska v1.6.2

Actually there are several references when mkv headers can be wrong or corrupt and have issues on different device/clients.  I know @speechles references mkvclean for issues like this.

Is that the only differences you see?  At the same time Emby use ffmpeg/ffprobe to read the file headers.

Do you have server log and ffmpeg log if present for a specific example.

Hi there, what exactly happens when you try to play them?
