Foundation: _NSSetLongLongValueAndNotify crash on HTTPStream class

[Babu]

Hello Team ,

Few of our customers facing this crash(Got from Xcode crashes , crashlytics portal) at HTTPStream class. Not sure what NSoperation thread affecting this and making the app to crash , its not easily reproducible

How safe it will be if we rewrite this forloop

@synchronized(_buffer) {
            [_buffer getBytes:b1 range:NSMakeRange(i, 2)];
            if (EOI_MARKER[0] == b1[0]) {
                if (EOI_MARKER[1] == b1[1]) {
                    eoi = i;
                    break;
                }
            }
}

Are you using the old SDK or the new theta-client ?

I think there was a problem with high load on iOS with the old SDK due to the way the loop was constructed.

Swift Library for Open Spherical Camera API

FYI, I edited my previous comment. I simplified the function again only check frames once the buffer is at least 70,000 bytes, since my camera gives me frames that are 79,000 removed unused variables, unneeded ‘repeat loop’, unneeded catch block use bool variables to as flags to identify a valid frame added comments to the code left commented code that lets you check your fps FYI my camera gives me about 30 frames per second, and each frame is 79k bytes

Likely unrelated as it relates to Android.

Theta SC2 Livepreview not working in Android

We can solved it by using our own logic for retry the LivePreview command again, once the preview fire the EOFException then we can catch it and fire the same command again after minor delay i.e. 0.5 second. It means you can fire command after 0.5 seconds when your first command failed.

Question about getLivePreview by THETA SC2 on Android

I want to get live preview by Theta SC2 on Android. (I’m using the https://github.com/ricohapi/theta-api2.1-android-sdk) But LivePreview screen is Sometimes all black and I can’t see a thing. Always black when connecting for the first time. Do you have any solutions? Would it be possible to get live preview by Theta SC2 on Android?

from tamy, but for Android

The theta sample app here: https://github.com/ricohapi/theta-api2.1-android-sdk does have a bug where the live preview goes black on the SC2. If you are knowledgable in java, an EOFException occurs in readMJpegFrame() in MJpegInputStream. There is a relatively simple workaround if you are able to develop. Make the call to camera.getLivePreview again after after this occurs. Hope this helps!

Hello @craig : We are still using the old sdk. Does the new sdk supports project running with objc + swift tech or is it only made for swift project?

Can you open an issue on GitHub with this question?

The RICOH engineers seem to be responding.

theta-client uses Kotlin Multiplatform.

Kotlin Multiplatform | Kotlin Documentation

I think it can be linked to Objective C, but I am not sure.

The example provided to use the theta-client library is only in Swift.
