Fire TV Lite Transcoding

[stenweb 0]

Hi

I've noticed that the majority of my x265 videos, when streaming onto a Fire TV Stick Lite (https://www.amazon.co.uk/fire-tv-stick-lite-with-alexa-voice-remote-lite/dp/B091G31KSJ/ref=sr_1_1?keywords=fire+tv+stick&qid=1691495353&sprefix=fire%2Caps%2C125&sr=8-1), it causes my Raspberry Pi 4 to transcode the video. This doesn't happen with apps on other devices (e.g. iOS, iPadOS, Samsung TV, LG TV). When playing x264 videos, I don't get the same effect.

Hopefully I've included enough information below, but can provide more if needed! Screenshot of the details of the video too!

Hi.  That device is going to need to transcode some profiles of HEVC 10 bit when using the TV app.

Can you try sideloading our standard android app on the same device and see how that compares?

Thanks.

Yes - side loading worked! Thank you.

Will the main TV app be updated at some point with whatever changes are in the standard android app?

HI, yes we are working on unifying them. Thanks.
