javascript - Dynamically load video in embedded player -

-

i have video player on web page:

<object id='mediaplayerobj' width="320" height="285"                          classid='clsid:22d6f312-b0f6-11d0-94ab-0080c74c7e95'                          codebase='http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#version=5,1,52,701'                         standby='loading microsoft windows media player components...' type='application/x-oleobject'>                         <param id='movie' name='filename' value="">                         <param name='animationatstart' value='true'>                         <param name='transparentatstart' value='true'>                         <param name='autostart' value="true">                         <param name='showcontrols' value="true">                         <param name='loop' value="true">                         <embed type='application/x-mplayer2'                              pluginspage='http://microsoft.com/windows/mediaplayer/en/download/'                             id='mediaplayer' name='mediaplayer' displaysize='4' autosize='-1'                              bgcolor='darkblue' showcontrols="true" showtracker='-1'                              showdisplay='0' showstatusbar='-1' videoborder3d='-1' width="320" height="285"                             src="" autostart="true" designtimesp='5311' loop="true">                         </embed>                     </object>

i have left filename value blank because want dynamically set it. have grid view , load list of videos stored on our server. want player load movie server. here's javascript:

var grid = document.getelementbyid('<%=gvpresentations.clientid %>');         var cell = grid.rows[(+index) + 1].cells[2].textcontent;         var path = "d:\\presentations\\";         document.getelementbyid('movie').value = path + cell;

however nothing happens when change filename element. missing?

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...
