HTML5 audio and video support
13 avril 2011, parMediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
For older browsers the Flowplayer flash fallback is used.

Running ffmpeg command on Android results in "Unable to find a suitable output format for ' -map 0:v:0 -map 1:a:0'"
5 juin 2017, par Akash DubeyI am using this command for replacing audio of video and genrate new video having new audio. Here file1 is my video.mp4, file2 is my audio.mp3 and output would be the output.mp4 :
complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"};Below is My code :
private void changeAudioofVideo(String selectedUri, String videoPath) {
String[] complexCommand;
File f = new File("/storage/emulated/0");
if (!f.getParentFile().exists())
f.getParentFile().mkdirs();
if (!f.exists())

Why when recording video using ffmpeg command line when playing the video it's running very fast ?
31 mai 2013, par Revuen Ben DrorThis is my code in Form1 :
private void StartRecording_Click(object sender, EventArgs e)
{
ffmp.Start("test.avi", 25);
timer1.Enabled = true;
}The timer tick event :
private void timer1_Tick(object sender, EventArgs e)
{
using (bitmap = (Bitmap)ScreenCapture.CaptureScreen(true))//(Bitmap)ScreenCapture.CaptureScreen(true))
{
ffmp.PushFrame(bitmap);
}
}Then the code in the ffmpeg class i did :
namespace ScreenVideoRecorder
{
class Ffmpeg
{
NamedPipeServerStream p;
String pipename = "mytestpipe";
byte[] b;
//int i, j;
System.Diagnostics.Process process;
//IAsyncResult ar;
public Ffmpeg()
{
}
public void Start(string FileName, int BitmapRate)
{
p = new NamedPipeServerStream(pipename, PipeDirection.Out, 1, PipeTransmissionMode.Byte);
b = new byte[1920 * 1080 * 3]; // some buffer for the r g and b of pixels of an image of size 720p
process = new System.Diagnostics.Process();
//process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
process.StartInfo.FileName = @"D:\pipetest\pipetest\ffmpegx86\ffmpeg.exe";
process.EnableRaisingEvents = false;
process.StartInfo.WorkingDirectory = @"D:\pipetest\pipetest\ffmpegx86";
process.StartInfo.Arguments = @"-f rawvideo -pix_fmt bgr0 -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v libx264 -r " + BitmapRate + " " + FileName;
process.Start();
process.StartInfo.UseShellExecute = false;
process.StartInfo.CreateNoWindow = false;
//ar = p.BeginWaitForConnection(EndWait,null);
p.WaitForConnection();
}
public void PushFrame(Bitmap bmp)
{
int length;
// Lock the bitmap's bits.
//bmp = new Bitmap(1920, 1080);
Rectangle rect = new Rectangle(0, 0, bmp.Width, bmp.Height);
//Rectangle rect = new Rectangle(0, 0, 1280, 720);
System.Drawing.Imaging.BitmapData bmpData =
bmp.LockBits(rect, System.Drawing.Imaging.ImageLockMode.ReadOnly,
bmp.PixelFormat);
int absStride = Math.Abs(bmpData.Stride);
// Get the address of the first line.
IntPtr ptr = bmpData.Scan0;
// Declare an array to hold the bytes of the bitmap.
//length = 3 * bmp.Width * bmp.Height;
length = absStride * bmpData.Height;
byte[] rgbValues = new byte[length];
//Marshal.Copy(ptr, rgbValues, 0, length);
int j = bmp.Height - 1;
for (int i = 0; i < bmp.Height; i++)
{
IntPtr pointer = new IntPtr(bmpData.Scan0.ToInt32() + (bmpData.Stride * j));
System.Runtime.InteropServices.Marshal.Copy(pointer, rgbValues, absStride * (bmp.Height - i - 1), absStride);
j--;
}
p.Write(rgbValues, 0, length);
bmp.UnlockBits(bmpData);The ffmpeg command line is :
process.StartInfo.Arguments = @"-f rawvideo -pix_fmt bgr0 -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v libx264 -r " + BitmapRate + " " + FileName;And i checked with a breakpoint and saw that the variable BitmapRate is 25 .
And the timer interval is 40 .So it should fit for 25 frames per seconds.
But when i'm running the video file using MPC Media Player Class everything in the video is running very fast. I mean the video is 2,326KB size the video Length is 16 seconds .And everything in the video seems to mvoe very fast if i opend a new window or dragged a window somewhere in the screen i see it moving very fast and as it i moved and did everything in real .
I see on the video file details that : length 16 seconds. 1920x1080 and 25 frames per second.
So where is the problem ? i can't figure out.

Opencv crosscompile with ffmpeg and other 3rdparty for arm board
16 juin 2017, par Little ToothAfter buliding Qt5.5.1 for my arm board sucessfully, I am taking up to crosscompile opencv. Here are the steps :
First, I crosscompile 3rdparty :
a.libz
lmk@lmk-virtual-machine:/home/newdisk$ sudo tar -zvxf zlib-1.2.8.tar.gz
lmk@lmk-virtual-machine:/home/newdisk$ cd zlib-1.2.8

lmk@lmk-virtual-machine:/home/newdisk/zlib-1.2.8$ sudo vi Makefileand etit Makefile in some details :

/home/newdisk/optnew/opencv-rely/includeWhy can cmake find lib directory
-- Found ZLIB: /home/newdisk/optnew/opencv-rely/lib/libz.so (found suitable version "1.2.8", minimum required is "1.2.3")but cannot find include directory ?
/home/newdisk/optnew/opencv-rely/includeDo you have any idea ?
