I’m running infuse on my Apple TV 4K with a SMB share on my Synology NAS hooked up via ethernet.
Whenever I play a video file, there is a half second delay anytime I press play or pause or seek forwards or backwards. The use case I see every time with every video file is I’m watching the clip (it starts and loads just fine) and then I click the apple siri remote to seek forward 10 secs, infuse has a lag/delay and then the video starts playing again (sound will lag even more before). Plex doesn’t do this so I think my setup is fine.
The files are simple 720p .mkv video files. I also re-encoded one of them to .mp4 which plex showed it was playing as a Direct Stream (so no conversion necessary) and that one even lagged.
I can include a video clip showing this behavior if you want.
I already have “Transport encryption mode” set to disabled on my Synology NAS. I also tried using NFS and that behaved the same also. I also just now edited my share to use SMB2 and the delay was still there.
I used to have a Mac Mini hooked up to my TV and I’d stream content from my NAS just fine. Seeking forwards and backwards would take milliseconds.
I’m not seeing anything that’s standing out as an obvious problem, but one thing you can do to avoid the audio delay is change the Apple TV > Settings > Video and Audio > Audio Format > Change Format from Off to Dolby Digital 5.1 or Stereo.
I can show a video of how plex handles seeking in a video. It is near instantaneous, maybe a few milliseconds delay. With infuse, it’s like a 1/2 second delay. When you go to skip some commercials and press seek many times in a row, it’s like it’s in quicksand. It’s painfully slow and delayed.
Or if you seek backwards 10 secs, instead of it being instantaneous, there’s a delay of a half second for the video and probably a full second for the audio. You’ll see people’s mouths moving before the audio comes back in again.
According to this post, the dev team is still aware of this problem:
I’m no dev and have no clue why this is so hard to get fixed. What i know is that all other apps i’ve tried - Plex, MrMC, Emby and of course every app that uses the native player - don’t have this delay issue.
