unity3d - iOS; Unsupported Pixel Format -


my unity app uses camera feed multiple systems app uses; such vuforia, arkit, , general camera feed input.

the issue i'm having each 1 of these requests different pixel format, seems cause issue arkit. requires yuv, , don't know how natively switch camera pixel format this. error when try , launch arkit after others;

2017-08-21 08:51:38.749452+0100 ar_app[399:105849] [sensor] unsupported pixel format: 875704438

2017-08-21 08:51:38.749876+0100 ar_app[399:105849] [session] session did fail error: error domain=com.apple.arkit.error code=104 "unsupported capture session configuration."

userinfo={ nslocalizedrecoverysuggestion=make sure correct device , format being used capture.,

nslocalizeddescription=unsupported capture session configuration.,

nslocalizedfailurereason=input device and/or format of provided capture session not supported given configuration. }

at least, thats think issue is; it's not getting format in yuv. appreciated. . thanks.

yuv color space, there multiple formats.

ar_app[399:105849] [sensor] unsupported pixel format: 875704438

875704438 translates 420v (nv12) or kcvpixelformattype_420ypcbcr8biplanarvideorange: 

kcvpixelformattype_420ypcbcr8biplanarvideorange = '420v'

so have yuv pixel format, biplanar video range.

the arkit docs mention biplanar yuv format not type of range:

the pixel buffer’s contents encoded in biplanar ycbcr (also called yuv) data format

however unity arkit plugin check kcvpixelformattype_420ypcbcr8biplanarfullrange in didupdateframe:

 if (cvpixelbuffergetplanecount(pixelbuffer) < 2 || cvpixelbuffergetpixelformattype(pixelbuffer) != kcvpixelformattype_420ypcbcr8biplanarfullrange) {         return;     }

so in conclusion might not fact it's not full range, have no easy way test it. maybe can try forcing full range if camera , other modules support it.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
