Error occured - Decoder: init failed (android player 2026.8.0)

Plex Players

Server Version#:
Player Version#:2026.8.0

Longtime Plex pass user here and never had an issue until last week

My honor magic pad 2 displays this error message on any local playback of H265 files from my Plex server (qnap nas)

If I download the file from the Plex server it plays fine

I tried clearing cache, reinstalling the client and even a fully factory reset of android but still get the error

Today my phone also updated to the latest Android version 2026.8.0 and starting throwing the same “Error occured - Decoder: init failed”

I have now manually side loaded and older version 2026.5.0 and the issue is fixed

I think there is a bug in android app 2026.8.0 that prevents local streaming of H265 files

I got this error message when selecting the TrueHD/Atmos track on my Pixel 9a. Choosing anything else than that track fixed my problem. (I chose regular AC3 and launched the movie again.)

@philippemorin123 Plex is investigating of the problem with TrueHD 7.1 audio. I see the same on my Pixel 6a.

@emu03 Can you provide a set of android client logs that capture the problem?

I’ve not seen any other reports of problems with HEVC video. The logs may show what is going wrong.
