hi guys, I'm a user of plex and video station on synology, I'm testing emby and it works great ! I don't understand how video can stream without need of transcoding VS plex and emby but that not the point. during my tests, I purchased monthly premiere license to test material acceleration : a transcode consume 98% of my CPU, now with HA it consume 28% but, I have now transcode buffer problem : without material acceleration, transcode buffered 10/15 seconds, the video can be streamed but CPU goes to 98% with material acceleration, transcode buffered 3 seconds every 3 seconds so the video freezes every 2 seconds but CPU goes to 28/30% I use a mkv file with pgs subs to do a stress test, I want to test emby in every case before buying a full premiere license for many users but if one user cause 90% of CPU, others cannot use it and my license is useless. why material acceleration causes that ? emby plays transcoded temp files faster than ffmpeg created it. can someone explain me why and how to solve it please ? thank you synology DS916+ DSM 6.2-23824 Update 6 Intel® Pentium® CPU N3710 @ 1.60GHz emby 4.1.1.0 synology package behind synology ngynx chrome 74.0.3729.131 64 bits volume : 4x SEAGATE ST2000DM006-2DM164 7,2k SHR RAID here are my full logs hardware acceleration ON vs OFF HA_OFF.zip HA_ON.zip rundiags_20190510T135747UTC.log
