RPi 3 - ffmpeg crashes

[UT5eDL9 0]

Hey everyone,

 

I have one problem with certain mkv files which I cannot figure out at all and it is driving me insane.

 

It seems like some files are crashing the ffmpeg instanace but I cannot see a pattern from the logs and also not when compairing said mkv files to other mkv files that are playing fine. Here is an error log. Can you please tell me, why emby thinks it needs to transcode the stream?

Hi there, what Emby app are you playing from?

This happened from the chrome player. But it seems to also be happening from the iOS/Fire TV App.

 

Another issue with these movies is that emby cannot correctly recognize the video and audio streams. Emby always lists them under "Additional Parts"

Please attach the complete emby server log. thanks.

It looks like ffmpeg could not read the mkv files I packaged with MKVToolNix. I repackaged the films to MP4/M4V and it works now. Thanks for your replies!
