Server Version#: 1.41.9.9961-72009961 Player Version#: Client version 2025.20.0 (966828434) Hello, I’ve already exchanged a little with ChuckPa (thanks to him) about my problem, but I prefer to create a new thread so as not to pollute the other thread. I have a Synology DS425+, with the latest ve…

Why I have a feeling Synology Support is pushing responsibilities to someone else around the whole dept and/or outside Synology, Not aware of what is going on from other dept of the company? And yes, why specifically HEVC? It’s the whole hardware transcoding that’s not working, isn’t it?

I questioned the HEVC comment and got this response today… I apologize for any confusion caused. My previous response referenced issues not only related to H.265 (HEVC) but also H.264 (AVC). As you have observed, we have disabled hardware transcoding via the kernel graphic driver, so any applicati…

Synology said they disable the function. Then they expect 3rd party companies like Plex to do the necessary to ‘enable’ it? Pardon my very little knowledge of programming but why ask 3rd parties to do the dirty work of ‘enabling it’ when they admitted they are the ones who ‘disabled’ it? Secondly,…

On DSM 7, Plex has no privileges beyond that of a normal user. Unless DSM permits access to a feature / capability, we have no access to it. The scripting / Plex configuration is dependent on the Synology-provided function video-driver.

If someone is willing to try Channels DVR free trial and submit diagnostics, I may be able to gather more details about what’s going on. EDIT: Or maybe someone tried Jellyfin or Emby? Do they have the same issue?

Given BeeStation, with the same J4125 CPU can do HW transcoding and the DS425+ cannot, both also with the same 5.10 kernel but different firmware, seems to indicate this is a Synology product/marketing driven decision.

Another response from Synology today… Regarding your concern about the removal of hardware transcoding support for HEVC (H.265) and AVC (H.264) on the 25-series models, we would like to provide some clarification. HEVC/AVC technology involves licensing requirements. We have previously negotiated …

The notice regarding the discontinuation of HEVC, AVC, and VC-1 support dates back over a year and concerned Synology applications (notably Videostation). Moreover, on Plex, hardware transcoding still works perfectly on “older” models (DS920+, DS423+, etc.). The excuse of the HEVC licensing cost is…

As part of our roadmap, starting with products released in 2025 and beyond, even if the CPU supports hardware transcoding, we will no longer provide the driver required to enable it. An exception is the BeeStation Plus, where we specifically obtained the appropriate licenses and paid the required f…
