do you mean --vfs-read-chunk-size 0 because i can not find any param --vfs-chunk-size 0 in https://rclone.org/commands/rclone_mount/
I already set ‘–vfs-read-chunk-size 0’ but it still not work
Did you try that with --buffer-size 0 ?
Both of them are setting to 0 but still not work:frowning:
Try setting --vfs-chunk-size 0 but --buffer-size 16M - does that help?
I’m sr but i still can not find any option name --vfs-chunk-size it may be --vfs-read-chunk-size ???
I’m sr when i set setting --vfs-read-chunk-size 0 and --buffer-size 0 that ios 12.1 can load movie but i need to wait nearly 4 minutes (without screen off) to load movie. The funny thing is server service seem to do nothing in all of time (just run about 200~500kbyte/s) after that in last second it load normal (over 3mbyte/s) and ios can load movie normal
I’m not sure why you are going for the most complex route to play a movie on a IOS device.
Did you check out Infuse if for some reason you don’t want to use Plex or Emby?
because if i use plex that use VPS to recompile video so my VPS always shutdown because use to much CPU, i using 4 core CPU and cannot view a movie to the end
If you want to play directly though, you’d have to convert to a more friendly IOS format anyway so you have to bite the bullet somewhere as they say.
Infuse also plays directly from Google Drive but the encryption bit would be missing.
i sr but i do not use GG driver 
i don’t thing this architect is complex just mount a drive and open file by range from http. but there are some thing stupid on IOS 12.1, i can not understand
