Keep Getting Booted Out of iOS WebVR

I'm having a serious problem that, for the life of me, I cannot figure out. I've done a million tests to try and eliminate the variables, but no luck.

Basically, whenever I'm viewing my virtual tour via WebVR stereoscopic on my iPhone 7 Plus, I eventually get booted back to the 2D start scene.

This can happen in any of the 17 scenes. It can happen right after getting into a new scene....or up to a minute or more later.

I suspect it might have to do with the HTML5-VR Audio Plugin by spacerywirtualne, but I'm not 100% certain. When I get rid of 3D sounds but leave in 2D sounds, the crash doesn't happen - at least not yet, anyway. No sound files also result in no crash.

The crash never happens when viewing 2D on the computer.

I'm running an iPhone7 Plus, iOS 11.2.6, krpano 1.19-pr14, and HTML5-VR Audio Plugin ver 3.1.0

I've not had any issue like this before.

Here's a link to the tour:

Any help would be much appreciated.

Tnx indexofrefraction,

All of my sound files are:
mp3
16000Hz
32bit
32kbps CBR OFL

Are you using the HTML5-VR Audio Plugin?

spacerywirtualne, the creator of the sound plugin, is checking out the sound files/folder to see if he can spot any issues. Will post back here if anything is found.

Klaus, thanks for the suggestion. Each of my cube images are 1536x1536 - which is a very standard size. Reducing the size would mean a pretty significant quality hit.

I did, however, save the overall jpg quality down to get all the images nearly half the file size. The tour still crashed in Safari.

However, I did a test in Chrome on the iPhone (even though you can't get rid of the menu bar) and it made it though the entire tour (including playing all the sound files) with no problem at all.

My guess is that something in Safari is the problem; perhaps connected with the sound plugin I'm using.

Zitat von indexofrefraction

as said, try to re-encode all files with mp3, vbr, 41.1 khz
clear your caches, restart, and then see if it still crashes.
in my tests cbr and non-standard hz settings did lead to crashes,
specially when playing multiple files at the same time.

indexofrefraction, I'm re-encoding now. Did you mean 44.1hz? 41.1 seems like a non-standard frequency. ?? Tnx

Tnx index. Yeah, chrome works just great - no crashes - on both iOS and the latest android. I’m going to test the new sound file encoding and report back.

Well, I changed every sound file to 44.1Hz, VBR but it still crashes in Safari iOS.

Yeah, tnx. I did discover that no sound files = no crashes. No 3D sounds = no crashes. Even if I have just one scene with 3D sounds it will eventually crash.

What audio solution are you using? Does it have both 2D and 3D sounds?

Piotr, I didn't have any crashes with your test scene, but many times when I would go to play a sound file in WebVR the first half second of the sound is cut-off. This was also a problem with my tour - the first time you play a 3D sound.

I'll keep testing your tour to see if it crashes. Sometimes on my tour it would not occur until you are at the 6th or 7th scene - sometimes later.

Tnx
