ios - Multipart upload using Quickblox for large files -

-

i using quickblox backend service , far has been great, having trouble uploading large video files.

here's how upload video files using quickblox ios sdk:

[qbrequest tuploadfile:self.videodata filename:@"testing" contenttype:@"video/quicktime" ispublic:yes successblock:^(qbresponse *response, qbcblob *blob) {             //success          } statusblock:^(qbrequest *request, qbrequeststatus *status) {              // update progress             nslog(@"completion : %f", status.percentofcompletion);          } errorblock:^(qbresponse *response) {             //         }];

this works fine of time, when self.videodata bigger, 20mb, app crash. after doing research on stackoverflow, looks right way upload large files server without crashing app multipart upload.

how can multipart upload quickblox? i'm willing use rest api if ios sdk not work.

i need know if possible or not, , if yes how started.

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a
