Synology is doing a staged rollout of DSM Version: 7.2.2-72803 (2024-08-26). Plex users should note that this update may break Plex and Plex themselves is apparently issuing an update that may (as of this post) only be available to Plex Pass users. See Reddit links below for direct links to the updated Plex installer. Read the release notes carefully as there are some big changes in this update.

4. Starting from this version, the processing of media files using HEVC (H.265), AVC (H.264), and VC-1 codecs will be transitioned from the server to end devices to reduce unnecessary resource usage on the system and enhance system efficiency. These codecs are widespread on end devices such as smartphones, tablets, computers, and smart TVs. If the end device does not support the required codecs, the use of media files may be limited. Refer to this article for workarounds. In addition, please note the following exceptions:
   • Surveillance Station on DSM will continue to support server-side processing of AVC (H.264) streams, see the release notes.
   • Deep Video Analytics (DVA) series models and VisualStation clients will retain support for AVC (H.264) and HEVC (H.265) codecs.
5. To ensure package compatibility, Advanced Media Extensions (AME), File Station, Media Server, Surveillance Station, Synology Drive, Universal Search, Synology Photos and Snapshot Replication will automatically update to the latest version.
6. Video Station is not available on DSM 7.2.2. Refer to this article for workarounds to stream videos to end devices.
7. Updated Storage Manager to 1.0.0-00502 to fix issues. For more information, see the release notes.

This makes sense - for example, the DS-723+ I have - any transcoding is on the CPU cores only, as it does not have a GPU...

Transoding is not as much needed as it was, as most set top boxes and mobiles have very efficient playback capabilities now... HW support or SW support with CPU/GPU capabilities...
