Hi, thanks for the builds! I’m running the Windows x64 Build, trying to improve the handling of Live TV from my DVB-T2 tuner. My hardware is pretty low power, but capable of playing HEVC with hardware decoding. When I start a TV channel, Plex always wants to transcode. On the official build this w…

The new IOS/Android clients don’t direct play MPEG2. Make sure to turn off HEVC encoding for non-HEVC Sources in the server transcoder settings. [image] Probably also want to ensure it is disabled for recordings. [image]

It shouldn’t be necessary to Modify HEVC transcoding on the server side unless you are running an early version of the New Experience clients. 2025.17 and later should force an h264 transcode for LiveTV regardless of this setting.

you dont need to show me the buch of licenses which are included in plex. i gave you a advise. so this was not a proper answer. you do provide the sourcecode of the ffmpeg sourcecode as required by the gpl, but you do not provide the modifications. this is a violation of the license. but i’m not her…
