Hi emby team,

say hello and welcome back to an old Error ๐Ÿ˜ž

since the update of the emby server version from 4.6.x to 4.7.x an old an previously resolved error is back ๐Ÿ˜ž
When playing a 4K HDR file that has a Dolby Atmos (TrueHD) audio track the new server version (from 4.7.0.1 toย 4.7.0.4)ย is being transcoding not only the audio track but also the video track

what costs a lot of CPU and more important picture quality.

The old server version (4.6.7.0) works as designed. The video is playing direct and only the audio track is being transcoded!

because I still have a backup of the old server version 4.6.7.0 I played the exactly same file once with 4.6.7.0 and once with 4.7.1.0.
search the logs for "Und taeglich gruesst das Murmeltier.mkv"

as I already described:

4.6.7.0 - no video transcoding (direct play) only the Dolby Atmos track is beiing trancoded to AC3

4.7.1.0 and above - video and audio is beiing transcoded ๐Ÿ˜ž

the logfiles from both server versions are attached here

PS: the problem of transcoding video that doesn't need to be transcoded already existed in earlier versions of emby server/LG App combinations but has been fixed sometime. now it's back ๐Ÿ˜ž

PPS: if this topic belongs to emby server please move it... I can only reproduce the problem on my LG TVs but maybe it's a general server prob.

Is there any chance to downgrade emby server, and if so, where can I download the old versions?ย
