How to save two camera's data but not influence their picture-acquire speed?

I am using a multispectral camera to collect data. One is near-infrared and another is colorful. Not two cameras, but one camera can obtain two different kinds of images in the same time. There are some API functions I could use like J_Image_OpenStream. Two part of core codes are shown as follows. One is used to open two streams(actually they are in one sample and I have to use them, but I am not too clearly with their meanings) and set the two avi files' saving paths and begin the acquisition. // Open stream retval0 = J_Image_OpenStream(m_hCam[0], 0, reinterpret_cast<J_IMG_CALLBACK_OBJECT>

问题 I want to convert this answer's code to imshow . It creates a movie in MOVIE2AVI by %# preallocate nFrames = 20; mov(1:nFrames) = struct('cdata',[], 'colormap',[]); %# create movie for k=1:nFrames surf(sin(2*pi*k/20)*Z, Z) mov(k) = getframe(gca); end close(gcf) movie2avi(mov, 'myPeaks1.avi', 'compression','None', 'fps',10); My pseudocode %# preallocate nFrames = 20; mov(1:nFrames) = struct('cdata',[], 'colormap',[]); %# create movie for k=1:nFrames imshow(signal(:,k,:),[1 1 1]) % or simply

I am wondering if the HTML5 <video> tag now supports playback of .avi format video files. Short answer: No. Use WebM or Ogg instead. This article covers just about everything you need to know about the <video> element, including which browsers support which container formats and codecs. There are three formats with a reasonable level of support: H.264 (MPEG-4 AVC), OGG Theora (VP3) and WebM (VP8). See the wiki linked by Sam for which browsers support which; you will typically need at least one of those plus Flash fallback. Whilst most browsers won't touch AVI, there are some browser builds

I basically have an matrix of bytes. Each row (meaning byte[]) represents an image. How do I create a movie out of that (any format - avi, mpeg, whatever), and save it as a file? Each image can be one of the following: int JPEG Encoded formats. int NV16 YCbCr format, used for video. int NV21 YCrCb format used for images, which uses the NV21 encoding format. int RGB_565 RGB format used for pictures encoded as RGB_565. int YUY2 YCbCr format used for images, which uses YUYV (YUY2) encoding format. int YV12 Android YUV format: This format is exposed to software decoders and applications. I can
