Hardware Decoding on Steam Deck no longer working for flatpak version of Chiaki

[ranger149]

Context

Flatpak version

1.12.4

What Linux distribution are you using?

5.13.0-valve36-1-neptune (SteamOS)

What architecture are you using?

x86_64

Actual Behavior

1. Update all apps on the KDE Discover store and Install either Moonlight or Chiaka from the KDE discover store (such as Moonlight or Chiaki).
2. Launch said app, and get a hardware decoding error, such as it not being detected or available.
   This issue only occurs with two flatpak apps that I know of, Moonlight and Chiaki. The Moonlight AppImage does not have this issue. This issue is widespread for Steam Deck users:

See:

• https://www.reddit.com/r/SteamDeck/comments/12qfq7j/steamos_346_chiaki_error/

For example:

• Moonlight states: No functioning hardware accelerated video decoder was detected.

• Chiaki says failed to initialize FFMPEG decoder.

Further Info

I tested the flatpak MPV app, and was able to confirm hardware decoding was working in other applications

Hardware decoding is provided by the underlying KDE runtime; there's nothing we can do here I believe.

I'm closing this issue because it's not actionable here; please report an issue to the KDE flatpak runtime.

Even if it turns out to be an issue here, a fix will have to come as a pull request. I don't own a steam deck device and have no means to work on any issue specific to that device.

Thank you, It has since been reported and I believe a solution should be coming shortly. Take care.
