extract

I know there is a question similar to mine: Extract wav file from video file I am new to C++ and understand about COM library + directX is needed for video and audio. I been looking for tutorial and samples code but little success. My question is how do I code the application to take video file (any type) and saved the extracted audio as .wav in my application rather than using other applications such as graphedit or virtualdub? I'll second the motion to just use a build of ffmpeg to perform the audio extraction. It can be done in one easy command as opposed to most likely hundreds of lines of

after skimming all possible questions and answers, i'll try it this way. I'm programming an RTE, but didn't manage to successfully extract text in a contenteditable element. The reason for this is, that each browser handles nodes and keypress (#13) events in a slightly different way (as ex.g. one creates 'br', the other 'div', 'p', etc.) To keep this all consistent, I'm writing a cross-browser editor which kills all default action with e.preventDefault(); Following scenario: 1) User hits the #13 key (check) 2) Caret position detected (check) 3) create new p(aragraph) after the element the

I have a list of 'words' I want to count below word_list = ['one','three'] And I have a column within pandas dataframe with text below. TEXT | -------------------------------------------| "Perhaps she'll be the one for me." | "Is it two or one?" | "Mayhaps it be three afterall..." | "Three times and it's a charm." | "One fish, two fish, red fish, blue fish." | "There's only one cat in the hat." | "One does not simply code into pandas." | "Two nights later..." | "Quoth the Raven... nevermore." | The desired output is the following below, where it keeps the original text column, but only

If you have zziplib installed, you can use this code: <?php $zip = new ZipArchive; if ($zip->open('test.zip') === TRUE) { $zip->extractTo('/my/destination/dir/'); $zip->close(); echo 'ok'; } else { echo 'failed'; } ?> Make sure the user executing php (usually nobody,

I would like to merge polygon data and raster data into one dataframe for purposes of then using randomForests package in R. This involves first extracting the mean raster value per polygon. So far, I have the following: #load libraries library(raster) library(rgdal) library(sp) library(maptools) #import raster data r <- raster("myRasterdata.tif") #import polygon data p <- readShapePoly("myPolydata.shp") #extract mean raster value for each polygon ExtractMyData <- extract(r, p, small=TRUE, fun=mean, na.rm=TRUE, df=FALSE, nl=1, sp=TRUE) # note I have also tried this with df=TRUE and sp=FALSE

I am aware of the jQuery regex plugin of James Padolsey: http://james.padolsey.com/javascript/regex-selector-for-jquery/ But I need something different: The regular expression should search in the whole visible text of the web page. I want to get the text itself, not the element containing them. The following will match requirement 1, but not 2: $('*').filter(function() { return this.text().match(/\d\d\d/); }); Any idea how i can do this with a good performance? This should get you an Array of all matches. var text = $('body').text().match(/\d{3}/g); jsFiddle . 来源： https://stackoverflow.com

i have a serious problem. i would like to extract the content from tag such as: <div class="main-content"> <div class="sub-content">Sub content here</div> Main content here </div> output i would expect is: Sub content here Main content here i've tried using regex, but the result isn't so impressive. By using: Pattern.compile("<div>(\\S+)</div>"); would return all the strings before the first <*/div> tag so, could anyone help me pls? I'd recommend avoiding regex for parsing HTML. You can easily do what you ask by using Jsoup : public static void main(String[] args) { String html = "<html><head/
