avi

A couple of similar questions are on stackoverflow, but I haven't been able to figure this exact problem out. I want to get a list of the fourcc s for the avi codecs that FFMpeg can decode. I know how to get all the formats ffmpeg -formats and codecs ffmpeg -codecs but neither list gives me an accessible list of fourccs . Neither does the documentation I can find. I need this list, so that my application can access the fourcc of an avi file and determine whether to use ffmpeg or VfW (or DirectX ) to try decode the file. Is there some ffmpeg command that can give me this list? I don't know if

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 the Content-Type to the appropriate setting for the file switch($file_extension) { case "pdf": $ctype =

I am using VFW unit from JEDI wrapper on WinAPI. The code I am writing is intended to search user drives and detect warez (note: deciding if some file is legal or not is beyond scope of this question). We do MP3, WMA and some graphic file search. Now we want to detect illegal movies. I want to open AVI file, read some details from it and close it. I have the following code: uses WFV; //from JEDI api wrappers procedure TForm1.Button1Click(Sender: TObject); var lInfo : TAVIFILEINFOW; lFile : IAVIFILE; lFileType : string; lLenMinutes : integer; lFPS : integer; begin {init file} AVIFileInit; try

I need to play an avi video file and add it to a jpanel. All I need to be able to do is to play from beginning to end of the video and then proceed with my program. I don't need any seek functions or anything like that. What is the simplest way of doing this? preferbly without using xuggler if possible It easy to embed the VLC player inside a swing application using VLCJ . Here is a working example: public class PlayerPanel extends JPanel { private File vlcInstallPath = new File("D:/vlc"); private EmbeddedMediaPlayer player; public PlayerPanel() { NativeLibrary.addSearchPath("libvlc",

I am trying to get the fps from my camera so that I can pass it to the VideoWriter for outputting the video. However, I am getting 0 fps by calling VideoCapture::get(CV_CAP_PROP_FPS) from my camera. If I hardcode it, my video may be too slow or too fast. #include "opencv2/opencv.hpp" #include <stdio.h> #include <stdlib.h> using namespace std; using namespace cv; int main(int argc, char *argv[]) { cv::VideoCapture cap; int key = 0; if(argc > 1){ cap.open(string(argv[1])); } else { cap.open(CV_CAP_ANY); } if(!cap.isOpened()) { printf("Error: could not load a camera or video.\n"); } Mat frame;

There is an IP web camera that I wrote a .NET class for sometime ago. It's basically a Timer implementation that pings a snapshot CGI script from the camera every five seconds. The camera itself is very rudamentary; it does not have any sort of API for me to work with, the only thing I can do programmatically (remotely) is invoke this script. The script returns a 640x480 JPEG image. Simple. Now what I need to be able to do is take a days worth of these images, and create a "time lapse" AVI video stream out of it that will eventually be embedded into a web page. How can I do this with VB.NET?
