把x的值調到 1和+1之間再播放7三、製作*.wav檔:用wavwritewavwrite(x,fs,waveFile)將數據x變成一個*.wav檔,取樣速率為fsHz x必需是1個column(或2個columns) x值應該介於 1和+1之間 若沒有設定fs,則預設的fs為8000Hz8四、錄音錄音之前,要先將電腦接上麥克風,且確定電腦有音效卡(部分的notebooks不需裝...
声音档和Video档的读与写byMatlab 聲音檔和Video檔的讀與寫(byMatlab)作者：丁建均 國立台灣大學電信工程學研究所 1 一、聲音檔(*.wav)的讀取 •電腦中，大部分的聲音檔都是*.wav的型態•讀取：wavread •例：[x,fs]=wavread('C:\WINDOWS\Media\ringin.wav');可以將ringin.wav以數字向量x來呈現。

video = read(v,index) 只读取 index 指定的帧。 video = read(___,'native') 以 VideoFormat 属性指定的格式返回数据,并且可以包含上述语法中的任何输入参数。 创建一个视频读取器对象,并使用帧索引读取一个或多个视频帧。为示例影片文件 abc.mp4 创建一个VideoReader 对象。
v= VideoReader(filename)creates objectvto read video data from the file namedfilename. example v= VideoReader(filename,Name,Value)sets the propertiesCurrentTime,Tag, andUserDatausing name-value arguments. For example,VideoReader('myfile.mp4','CurrentTime',1.2)starts reading1.2seconds into the vi...
release(videoPlayer); ı want to save my new video with bounding box. I get an error on this line "a=step(videoPlayer,result);" and it's Error using vision.VideoPlayer/step _Too many output arguments; 1 output(s) requested but only 0 output(s) available._...
For example a *.wmv video length is 10 sec. Frame per second 50. Total frame= 10*50 =500 frames. But Matlab NumberofFrames function gives 351 frames. When same video start a blackframe, this time function gives 500 frames. What can I do? What is problem? I think that the problem ...
I'm using writeVideo to save a simple animation. However I encounter two annoying problems: for one, the first frame is shown for two seconds in VLC, for a frame rate of 1 which works properly for other frames. Secondly, VLC stops playback at the second-to-last ...
