SOLVED: Stream starts fast in browser, but slow on Android TV

[Curler1]

The only difference in the ffmpeg logs is that the TV is receiving 5.1 AAC in a TS container while the browser is receiving stereo AAC in a MP4 container.  The transcode speed is the same.

What kind of Android TV device is it?  And can you share the main jellyfin log via privatebin.net?

Thanks for checking!

I am using Google Chromecast with Google TV 4K 4th Gen. At the beginning Jellyfin worked fine and the problem just started a few months ago so I assume it is not the hardware itself. I also reset the device already and reinstalled the Jellyfin for Android TV App.

Here is the main jellyfin log:

I just checked my TrueNAS and one interesting discovery is that every time I start the stream on Android TV, the connection between my Jellyfin Server and TrueNAS is completely saturated. This only happens when I stream from Android TV but not when I stream from the browser. I attached the screenshot, the pink spikes is when I start the stream on Android TV. In between the pink spikes I was starting several streams on my browser which only results in little traffic between my Jellyfin Server and TrueNAS.
