avi

问题 I am trying to make a simple node-webkit app that lets you play .avi videos (which should work both on windows and mac). Is there a way to do this with node-webkit? 回答1: It is unlikely you will be able to just do this with Node-Webkit. Especially since the official webkit does not support AVI. Your best bet is to use an external application like libav (avplay) or use node to serve a webpage that has a player capable of playing the content and just let the users browser do the work. (Flash is

问题 Howdy! For a research project (in Java), I've got to find some way to save an animation of a graph into some file format. Now I've already got the program working fine drawing each frame. The problem is, short of learning the whole GIF or AVI file format, I have no idea how to assemble the frames programmatically into some sort of animation or video file. File formats don't really matter--input or output. I just need some way to put the frames together and save! Right now I'm thinking the

问题 I want to read an AVI File in Matlab. I tried it according to this link: http://inside.mines.edu/~whoff/courses/EENG512/lectures/other/Matlab_movies.pdf : clear all close all movieObj = VideoReader('ap001_BL0_SP2_cam03_compressed.avi'); % open file get(movieObj) % display all information about movie nFrames = movieObj.NumberOfFrames; %shows 310 in my case for iFrame=1:2:nFrames I = read(movieObj,iFrame); % get one RGB image imshow(I,[]); % Display image end I get the following error: Error

问题 First of all, I'm new to C#, so bear with me. I am making an application, that shows an .avi file in windows media player like this: private void button1_Click(object sender, EventArgs e) { axWindowsMediaPlayer1.URL = @"C:BlaBla\Family Guy\Season 10\S10E16.HDTV.x264-LOL.avi"; } I've found out that you cant fastforward or fastrewind in an .avi file, because it's not indexed. But using the WMP-slider of axWindowsMediaPlayer1, you can set the file to play at a specific point. For instance, start

问题 I want to extract audio from a video file as a MP3 using c#. The bit-rate of the audio should be able to specify. Could someone please help me on this? I have already looked at "whether" but I'm not sure whether it is possible to do with "whether" without prompting CMD. Please don't suggest me following article. it doesn't work properly for file that are larger than 700mb http://www.codeproject.com/Articles/7388/A-Simple-C-Wrapper-for-the-AviFile-Library 回答1: You could call an ffmpeg binary

问题 The problem explained I am trying to extract the recorded date from some AVI files (in this particular case created with a Sony DV camcorder). Starting with no knowledge on the format, I have been able to make sense of the metadata in the main chunks in the file using this reference: https://msdn.microsoft.com/en-us/library/windows/desktop/dd318189(v=vs.85).aspx I been searching a lot to find out where the date is stored, but without any luck. The closest that I came was the following answer

问题 I've been trying to get emgu to save same webcam video to file The problem is opencv only ssupports avi, and avi does not seem to suit a format like X264 very well. Could I use Gstreamer to do this for me in C? It would be good if I could choose the file format and container type too. It would be good if I could use a format like schrodinger dirac. I'm new to GStreamer so I'm not quite sure if I'm on the right track here. EDIT I've managed to capture the webcam video using gst-launch-0.10

问题 I've built a Windows Phone class to convert some WriteableBitmap into a AVI Full Frame (Uncompressed). Videos are really huge. Is there a simple codec implementation existing, like a codec that just zip images, or something that is making a next/previous XOR then zip it in jpeg? Windows Phone doesn't allow any unsafe code and most DLL cannot be wrapped into a C# WP library. So that's why I'm coding something from scratch. Note that I'm more efficient at coding from scratch than in studying C+

问题 I'm trying to make a PHP script to download an AVI-file. The file is on my server and I want to send it to the user. I have made the following script but when I run it, I will only get a 0 KB large AVI file. Can anyone tell me what I am doing wrong? $file_path = "downloads/test.avi"; // Get filename $filename = explode("/", $file_path); $filename = $filename[count($filename)-1]; if(file_exists($file_path)) { $file_extension = strtolower(substr(strrchr($file_path, "."), 1)); // This will set
