Severe playback issues. Constant buffering

Hello,
I am running Infuse Pro 7.4.2 (4192) on iPad with ipadOS 15.5 installed and I am experiencing severe playback issues on nearly all files (4K, 1080p, etc.)
All files are stored on a diskstation NAS using a smb v2 share. When I start playback of a file, I get the spinning wheel for about 30 seconds before the video finally starts playing. After 1 - 2 minutes the video freezes and I get the spinning wheel again. This even occurs when the file is stored locally on the ipad and played back from there. I can rule out any network issues as everything works flawlessly when playing back the file using VLC on the ipad or Infuse on the ATV4K. Deleting an reinstalling Infuse from scratch didn‘t resolve the issue.
Any ideas or clues?

If you have a chance, would you be able to upload one of the problematic video files so we can review it here?

@james
I have not had time to upload any video files. As a matter of fact, the relevant files are rather large in size (>15 GB) and uploading them will take a very long time.
I will try to describe the problem in detail. I am running the current release of Infuse on an ATV4K, an iPhone 13 Pro, an iPad Pro (2018) and on an iMac (2017). The problem only occurs on the iPad and on the iPhone and started to surface a couple of releases ago (I cannot say exactly when it began). Neither the ATV4K, nor the Mac are affected by it. As I have stated above, the “problematic” files played back fine with previous releases of Infuse on the iPad/iPhone and still do using an alternative player (e.g. VLC). Therefore I can rule out any network related issues.
It seems to me, something broke a few releases ago and only iOS and iPadOS are affected.
Hopefully I provided enough information for @james to look into the problem. If there was a chance to install older versions of Infuse on the iPad I was able to tell when the problem first occurred.

Can you try running a speed test in Infuse? More info on this can be found here.

I get an average speed of 122 Mbps.
As I said before, the problem occurs even when the file is stored locally on the device.

Hello,
I did some further testing with infuse 7.4.4 on ios 15.6.1. Unfortunately the problem is still there. :frowning_face:
It seems to me, the playback issues are related to the way infuse is handling the wireless network connection on ipad and iphone. After downloading the problematic files to the devices, playback is fine. Once again, playback of all problematic files is working flawlessly without any stuttering or buffering using VLC player (on the same network).

Can you try adjusting the SMB version in Infuse to see if this makes any difference in your environment?

This setting can be found under the Advanced tab in the share’s settings.

I‘ve done that already and tried various SMB settings with no success. Even switching to the nfs protocol didn‘t solve the problem.
The problem only occurs on the ipad and on the iphone ,which both use wireless connections. On the ATV and on my imac, with wired ethernet connections, everything is fine.
Again, this behavior was introduced a couple of releases ago and must lie within infuse. The setup of my network has not changed since. On my ipad, Infuse reports an average network speed of 122 Mbps…

This is also the case with my iPad. When I use the mx player of my Android phone to play the same video, there is no such problem. This often happens when playing 4k UHD REMUX files

After running more tests I am absolutely positive this issue has been introduced with version 7.3.7. In my opinion, the „ultra-optimized streaming cache“ is causing the problems. Changing the streaming cache settings from auto to legacy or memory only has no effect. When playing back the problematic file with VLC Player on the same iPad everything runs absolutely smooth. With Infuse it buffers and stutters like hell.
@james : There must be a way to fix this for good. Is it possible to revert back to the old setting prior to 7.3.7.?
Until this gets fixed somehow, Infuse is useless to me. :frowning:
