  • grab non consecutive frame from IP camera

    16 juillet 2012, par Mel

    I'm working on project where I need to retrieve frame from IP camera every second (or two) and process it some way.
    After initialization of capture with

    CvCapture* capture = cvCaptureFromFile(ipSource);

    I'm getting the frames from a loop where I introduce one (or two) second(s) delay -

    frame = cvQueryFrame(capture);

    Problem - I only get consecutive frames (from buffer I suppose), not the frame in moment I try to get it.
    What should I do to get frame in the moment I want to ?

  • How I can keep the camera preview fps same as that in CamcorderProfile.videoFrameRate

    30 janvier 2015, par suitianshi

    Say I have a video recording app. The user press down a start button to start recording and lifts finger up to stop. For some reason I am using Camera.onPreviewCallback to receive byte data from preview and output it as a mp4 file(with ffmpeg libs). Suppose the user long presses start button for 10s, and I get 100 frames totally.How can I let my video last for exactly 10 seconds ?

    There are some problems :

    1. The fps of camera preview is not stable, so I can only get total number of frames as well as the desired duration when the recording stops.
    2. ffmpeg requires a fps field to be set when encoding(). I don’t know if I could set the fps value at the last time(that is, when I get all frames). The documents says it should be set when calling avformat_write_header(), so I guess not.
