I’m currently running into an issue where I’m trying to load a Draco compressed model using the Draco Loader of threejs on mobile browsers and it seems to hard crash during the call to the `.load method. IOS Safari not and Chrome version 88.0.4324.93 on an Android - Pixel 2 XL are the ones I’ve tested so far. The exact same models seem to render completely fine on web browsers with no issues.
This is a screenshot of the error I’m receiving which states memory access out of bounds

I’ve tried adding console logs to the onProgress, onLoad, and onError callbacks. The onProgress seems to fully complete but after that, before the onLoad callback can run, it crashes and the onError callback isn’t called either.
Anyone have any ideas on how to go about solving this?

My vuejs nuxt portfolio(https://gunjankadu.com/)is not opening on ios phones but working flawlessly on all other devices. On IOS devices only a red spinner is shown and nothing more.
What can be done?
A script "tag.js" took time to load, which I have currently disabled but still not working.
I had a look on your application and found out two problems.
First was about regular expressions, It seems Safari doesn’t support look behind yet. One alternative would be to put the / that comes before in a non-captured group, and then extract only the first group (the content after the / and before the #).
/(?:\/)([^#]+)(?=#*)/
And second is about The minimal-ui viewport property that you can find out more here
Look at all your js/vue files especially in store. And see if any variable used is not imported. Nuxt in SPA mode doesn't detect those kind of errors and surprisingly the UI gets stuck on loading only on iOS. Very weird but scratched my brain over it for a day.
I'm using the Microsoft sample DX11VideoRenderer to render real time video in Windows 10. When I run just one stream, the video looks great. However when I run more than 4 or 5 streams, some of the video in their respective windows start blanking out intermittently. The effect can be over just a portion or all of each video window.
Also I get a few intermittent errors from this function call in my log file:
hr = pVideoContext->VideoProcessorBlt(m_pVideoProcessor, pOutputView, 0, 1, &StreamData );
The error returned is: E_INVALIDARG One or more arguments are not valid 0x80070057
I'm only using the Presenter.cpp and display.cpp modules of the DX11VideoRenderer in my code. The source is located at:
DirectX video rendering sample
My initial suspicion at this stage is that DXVideoRenderer may not be thread safe. I found this information about multithreading: Introduction to Multithreading in Direct3D 11 which states:
While the use of a device context (ID3D11DeviceContext) is not thread-safe, the use of a Direct3D 11 device (ID3D11Device) is thread-safe.
But it seems that since I'm using separate instances of the CPresenter class for each window, there should not be a problem with ID3D11DeviceContext not being thread safe because each window should have it's own instance of ID3D11DeviceContext.
Does anyone have any experience or ideas about this DX11VideoRenderer software sample and what might be causing this problem?
Thank you!
-UPDATE-
I have been able to duplicate the problem with just one window so it no longer appears to be a threading issue. If I manually resize the window many times I can sometimes get the video in the window to flicker. When this happens I see in my log that the same function call to VideoProcessorBlt() had a failure with the same return code, E_INVALIDARG.
If I manually resize the window many times I can sometimes get the video in the window to flicker. When this happens I see in my log that the same function call to VideoProcessorBlt() had a failure with the same return code, E_INVALIDARG.
This behaviour is not documented by Microsoft.
The problem is the same with DirectX9, but the error occurs with IDirect3DDevice9::Present, just after VideoProcessBltHD.
The HRESULT code is 0x88760872, and 0x88760872 is not documented.
So when resizing window, the error can occur.
See H264Dxva2Decoder :
In Dxva2Renderer.cpp, check for HANDLE_DIRECTX_ERROR_UNDOCUMENTED.
The strategy I choosed is to pause the video if playing (see WindowsFormProc and WM_ENTERSIZEMOVE/WM_SYSCOMMAND),
also, this avoid flickering.
Doing this, the error disappears.
PS: normally this error can be safely ignored.
I think this error is just there to tell you that when the window is resized, the underlying API is struggling to synchronize the DirectX presentation with your HWND, which changes size quickly.
We are developing web app, that uses framework that uses indexedDB. All was going fine, but then we tested it on iPad and suddenly it didn't load the page at all. Thought it would be some minor issue, but after some tests we found out, that the app is crashing on:
TypeError: null is not an Object validating 'request'
It crashes on the line :
var request = indexedDB.open("FMVare",415);
This stores null in the request variable so then after that there is:
request.onerror(...)
Which will get us the error message, written above.
I spent one day looking for a fix, but only found that iOS implemetation of indexedDb is "buggy". But I cant even open a database, so there probably is problem somewhere else. My colleague also told me, that it was working fine like 1 month before, but the file with this implementation (according to git) didn't change... ever.
I tried using pollyfill to change it to the WebSQL, again it worked everywhere except iPad browsers (Safari, Chrome). This time it was throwing different error, which I only could google as far as some SQL syntax error, which obviously couldn't be the case, if it is working everywhere else.
I have tried some suggestions, which said to replace in that pollyfill indexedDB with _indexedDB etc. but again, it worked everywhere but iPad.
When I log the variable request, it returns null. If I log indexedDB or window.indexedDB, it returns IDBFactory object, so it's there, but the .open method is failing, without calling .onerror or .onsucess method.
Since I really found many people complaining about indexedDB bad implementation on iOS, it means they were able to use it. So what could be the problem in my iPad? I mean I can try update to iOS 9, but that's not exactly what are we trying to achieve.
I tried deleting cache, changing version number(greater and smaller), creating different database (different name), pollyfill... but still can't get it working, everytime i call indexedDB.open(databasename), it returns null and crashes.
Any ideas?
EDIT:
The error I'm getting with shim is
Error in sysdb transaction - when creating dbVersions.
Then I get the SQLError object with
"code: 5"
and
"message: could not prepare statement (1 not authorized)"
The error happens in createSysDB(success, failure) function of the shim.
UPDATE:
I tried an app on iPad called WebView Rendering so i could try if WKWebView would be capable of running my app. And it was! So the problem really was the UIWebView support of IndexedDB.
Seems very strange to me though, that you can't use IndexedDB on iOS Safari even after update on latest iOS version.
Is there a way to view the iphone console logs without having a mac ?
It used to be possible using the iPhone Configuration Utility but it does not seem to be available any longer.
I saw a tool called iTools but it seems to require a 32bit version of itunes which is also not available any more.
Given an iPhone device + windows + linux, Is there any workaround / tool to view the iphone console logs?
Realizing it is over half a year ago you asked this, but since it does not have an accepted answer yet:
I ran into this very same issue over and over, and got fed up with it, so I decided to have a go at writing a script that displays console messages in HTML, so you can just view everything in the webpage itself, without having to resort to a console-replacement or a tedious remote debugger (for which you, indeed, require a Mac), without having to modify each console call in existing code.
The key lies in 'replacing' the four main functions in window.console: log, warn, error and trace. This is done by redifining each method, adding own code to that, and calling the original method in the end. Jakub Fiala wrote the basic script for that, on which I built the rest: https://gist.github.com/jakubfiala/8fe3461ab6508f46003d
I dubbed it 'MobileConsole'. It is quite unobtrusive and will 'catch' all console.log (or .warn, .error or .trace) events, and even bind to window.onerror.
I have created a separate page for this script with an elaborate explanation on how it works, including a demo, over here.
Download this from the app store onto the iphone, you can then view logs directly on the phone:
https://itunes.apple.com/us/app/console/id317676250?mt=8
Please note, this is an old app, it will crash when launched, then on reopening it will show you the device logs.
If that fails, here is a link to the iPhone configuration utility for windows:

What does the following error indicates
5/19/11 8:06:45 PM SpringBoard[9712] Error deserializing
wallpaper image: Error
Domain=CPBitmapErrorDomain Code=0 "The
operation couldn’t be completed.
(CPBitmapErrorDomain error 0 - No data

UserInfo=0x70b9c80 {NSDescription=No

Well, if you read the error message, it is telling you that a wallpaper was unable to be deserialised because no data was provided to the function named CPBitMapCreateImagesFromData. Pretty self explanitory.
Other than that, it sounds like you're either working on a jailbroken phone or trying to do things that aren't supported by the official iOS SDK - in which case my help ends here.
Or you're a user who is trying to understand why an image they set as a wallpaper isn't displaying and found their way to the iPad's console - in which case, this isn't the place to be asking.
This happened to me also, I think it's because most of the tutorials are written with an iphone in mind and I was using an iPad. I was working with an ipad and when following these tutorials i was getting this problem.
When you are creating the project I choose View based application. In the same wizard there's a combo box for 'iPhone' and 'iPad'.. If I leave that as iPhone then my application doesnt start in the simulator and I see the error you mention. If I set that to iPad then everything works fine.
I dont understand why that should make a difference tbh..
This happened to me, but only when I was not debugging, what happened was that in the dealloc function [super dealloc] was called at the top of the function rather than at the end. The "deserializing wallpaper" message is probably due to some sort of memory corruption that occurred since I had code after [super dealloc] trying to use pointers that were now garbage. I had NSZombie activated but it had no effect. Why this only crashed when I was not hooked up to the debugger is beyond me at the moment.
Thankfully this bug was fixed after a few diffs in source control, but initially I was pretty perplexed at the message and the fact that it was a bug where the debugger couldn't be used only induced more panic.
I'm sure you've long fixed your problem but I thought it'd be helpful to put this out there for others.
