Audio Fails to Play on Random Videos

[boardwarp 0]

Hullo! I'm running Emby in a Docker container and  trying to figure out why some videos in my library have no audio when played with Emby. Audio is fine for these files in VLC and other apps. I can't identify a pattern for impacted files, except that they tend to appear in chunks of sequential episodes. Even within  a single season, some files are muted while others aren't.

 

I enabled verbose logging and compared a muted and a normal file (filtered out webserver lines: `tail -f -n 0 .docker/emby2/logs/embyserver.txt | grep -v HttpServer`), but there was no significant difference: https://www.diffchecker.com/iWVlnnzD (Good video on the left in red, muted video on the right in green)

What is the audio format? Can you attach a copy of the media info from the bottom of the web app detail screen? Thanks.

Here ya go. Looks like the only difference is the muted video missing the "Codec Tag: mp4a".

Hi, that's only the media info of the audio track. Can you provide the complete media info for the entire file? Thanks.

@@arrbee99 are you able to reproduce with this file?

Do you know or does it matter what they're failing to play in - browser, Theater, everything ?

[Luke 42077]

browser.

[arrbee99 1815]

Tried that file in Firefox, Chrome and new Edge. All played video and audio ok. Firefox said direct streaming, the other two said direct playing.

 

This is just on Windows. Non of this Docker stuff.

Yup, same file from the same server sounds fine on my Android in the Emby app.
