ffmpeg record screen and save video file to disk as .mp4 or .mpg
5 janvier 2015, par musimbateI want to record the screen of my pc (using gdigrab on my windows machine) and store the saved video file on my disk as an mp4 or mpg file .I have found an example piece of code that grabs the screen and shows it in an SDL window here :http://xwk.iteye.com/blog/2125720 (The code is on the bottom of the page and has an english version) and the ffmpeg muxing example https://ffmpeg.org/doxygen/trunk/muxing_8c-source.html seems to be able to help encode audio and video into a desired output video file.
I have tried to combine these two by having a format context for grabbing the screen (AVFormatContext *pFormatCtx ; in my code ) and a separate format context to write the desired video file (AVFormatContext *outFormatContextEncoded ;).Within the loop to read packets from the input stream( screen grab stream) I directly encode write packets to the output file as shown in my code.I have kept the SDL code so I can see what I am recording.Below is my code with my modified write_video_frame() function .
The code builds OK but the output video can’t be played by vlc. When I run the command
ffmpeg -i filename.mpgI get this output
[mpeg @ 003fed20] probed stream 0 failed
[mpeg @ 003fed20] Stream #0: not enough frames to estimate rate; consider increasing probesize
[mpeg @ 003fed20] Could not find codec parameters for stream 0 (Video: none): unknown codec
Consider increasing the value for the 'analyzeduration' and 'probesize' options
karamage.mpg: could not find codec parameters
Input #0, mpeg, from 'karamage.mpg':
Duration: 19:30:09.25, start: 37545.438756, bitrate: 2 kb/s
Stream #0:0[0x1e0]: Video: none, 90k tbr, 90k tbn
At least one output file must be specifiedAm I doing something wrong here ? I am new to ffmpeg and any guidance on this is highly appreciated.Thank you for your time.

Issue in CV_FOURCC('H', '2', '6', '4')
16 décembre 2014, par AshwinI am trying to use H264 encoding type for compressing the live streaming from Camera (which is supporting the H264 codec) am getting below -
[I am using OPENCV 3.0 beta version (latest)in windows 7 64 bit system .My camera is also supporting H264 codec (find more details below) ]
My ffmpeg code got built with h264 lib :
This build was compiled with the following external libraries :
x264 20140826-git-dd79a61 http://videolan.org/developers/x264.html**error :**
Frame size = 1280x720
Could not find encoder for codec id 28: Encoder not foundERROR: Failed to write the video
Press any key to continue . . .Below is my code :
int main(int argc, char *argv[])
{
// QApplication a(argc, argv);
VideoCapture cap(0); //capture webcam
if (!cap.isOpened()) //if not successful then exit
{
cout << "Cannot open webcam";
return -1;
}
namedWindow("Camera feed", 1); //create window
cap.set(3, 1280);
cap.set(4, 720);
double dWidth = cap.get(CV_CAP_PROP_FRAME_WIDTH); //get width of frames of video
double dHeight = cap.get(CV_CAP_PROP_FRAME_HEIGHT); //get height of frames of video
Size frameSize(static_cast<int>(dWidth), static_cast<int>(dHeight));
cout << "Frame size = " << dWidth << "x" << dHeight << endl;
VideoWriter oVideoWriter("video.avi", CV_FOURCC('X', '2', '6', '4'), 30, frameSize);
if(!oVideoWriter.isOpened())
{
cout << "ERROR: Failed to write the video" << endl;
return -1;
}
while(1)
{
Mat frame;
bool bSuccess = cap.read(frame); //read a new frame from video
if(!bSuccess) //if unsuccessful, break loop
{
cout << "Cannot read frame from video file" << endl;
break;
}
oVideoWriter.write(frame); //write the frame into the file
imshow("Camera feed", frame); //show the frame in "Live Feed" window
cout << "Recording" << endl;
if (waitKey(30) == 27)
{
cout<< "Esc key is pressed by user" << endl;
break;
}
}
return 0;
}
</int></int>Here is the proof that my camera is supporting the H264 :
