The long-awaited update to SteamOS 3.4 (incl. hotfixes 3.4.1 and 3.4.2) for the Steam Deck was released today in the "stable" channel.

Unfortunately, besides all the nice improvements, there is also a less nice change: hardware de- and encoding (for video streams) has been disabled with this update.

This means that, for example, streaming FROM or TO the Steam Deck is now done exclusively in software (with corresponding effects on the CPU and battery).

If and when this change will be reversed is currently unknown.

UPDATE

The Hotfix 3.4.2 seems to have reverted this change.
