Video works on chrome, but not on Android App!

[Enissay]

Hi all,

As the title says: I have a video that works well on chrome browser, but not on my android app (tablet or firestick).

I wonder if anything wrong with it, a missing decoder ?

Worth noting I am deploying Jellyfin on a RaspberyPI 4 using docker, and it has been working fine so far until this video :-/

Please advise.

Hey @Enissay

Could you specify what you mean by "works well" and not mean?

[Enissay]

@Venson,

In details:
Works wellell: the video works fine as expected on chrome only
Not working: 2 cases here:
+ on android tablet, I get a green screen, but I can hear audio
+ on firestick, I get nothing but an error



Checking Jellyfin log, I see the below:

Looking at your Log files, to seems like your JF container is not correctly configured to access the Hardware acceleration features of your host.

[Enissay]

I believe the issue is: "Bit depth: 10 bits"
I've got another version of the video using 8Bits and it works fine.
This solves it.
Thank you @Venson for the assistance <3

For future reference, High 10 H264 video doesn't have great support with clients, so you're asking for transcoding with that type of file. It was popular with the anime community but you have to jump through some hoops to get it to work. Running an rPi as your server, I'd avoid High 10 h.264 encodes in the future, you'd have far better luck with 10-bit x265 (and maybe even AV1 honestly) as far as compatibility.
