Playback problem

[GOBOXS]

The stream looks fine to me to be honest. If the client cannot play the required audio it needs to be transcoded and if your server CPU is too weak that is nothing we can do and it is not a jellyfin issue. On iOS the app does not correctly detect multi channel audio support iirc so you have to manually set max audio channel to 6, but even that the server still needs to do remux but that should be less CPU intensive as most thing is now only stream copy.

Thank you for your reply , but i check more time and sure playback ios app problem , why ? i click play mkv file from mount google drive by rclone , it play direct stream , i jump 5 min , check server it direct play , and again jump 5 min , it back direct stream , i make python script put link inside strm file , python script connect with rclone , jellyfin connect with script by link inside strm file , when i click play on ios app or web , check server it direct play , i test again with plex and emby same file , both direct play on ios app , i don't believe jellyfin can not do better , and am sure playback ios app problem or in server some wrong . 

i share my script can do direct play with cloud drive . you can look , i add content to script and all direct play , note: this problem with all file from cloud drive and local drive , always direct stream , i never lucky play cloud drive and local drive with direct play , but play hls is direct play .
