video - ffmpeg segmentation with multiple mp4 files to HLS stream -

-

i'm trying segment multiple mp4 files .txt concatenate works, doesn't seem work.

i have concat.txt desired format:

file video1.mp4 file video2.mp4 file video3.mp4

etc...

and ffmpeg commands are:

ffmpeg -i concat.txt -map 0 -codec:v libx264 -codec:a libfaac -f ssegment \ -segment_list playlist.m3u8 -segment_list_flags +live -segment_time 10 out%03d.ts

unfortunately every mediaplayer drops error on playback.

i presume can't use method done concatenating. have concat mp4s single mp4, , segment mp4 final m3u8? or, can segment mp4s 1 one , concat .ts files better quality?

the ffmpeg concat demuxer requires same codecs input files, although container can vary. need make sure video , audio streams have same ids across files.

ffmpeg -re -f concat -i concat.txt -c:v libx264 -vbsf h264_mp4toannexb -r 25 -g 75 -c:a libfdk_aac -hls_time 3 playlist.m3u8

i used h264_mp4toannexb bitstream filter convert h.264 stream annex b format required mpeg-ts, set gop size 75 (3 seconds @ 25 fps) , used segment length of 3 seconds since each segment should start keyframe.

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

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
