  • Recording application output to video using FFmpeg (or similar)

    15 décembre 2011, par John

    We have a requirement to lets users record a video of our 3D application. I can already grab the individual rendered frames so this question is specifically about how to write frames into a video file.

    I don't think writing each frame as a separate file and post-processing is a workable option.

    I can look at options to record to a simple video file for later optimising/encoding, or writing directly to a sensibly encoded format.

    FFmpeg was suggested in another post but it looks a bit daunting to me. Is it the best option, if not what can be suggested ? We can work with LGPL but not full GPL.

    We're working on Windows (Win32 not MFC) in C++. Sample/pseudo code with your recommended library is very much appreciated... basically after how to do 3 functions :

    • startRecording() does whatever initialization is needed
    • recordFrame() takes pointer to frame data and encodes it, ideally with timing data
    • endRecording() finalizes the video file, shuts down video system, etc

  • How do hot switch video files in ffmpeg ? [closed]

    I want to switch videos, while one other playing. When I load new video few times, applicaton crashes, how do it correctly ?

  • How the seek frame while playing video ?

    16 mars 2012, par sherman

    I try do this :

    void Java_ffvideo_company_com_NativeCalls_seekFrame(
    
        JNIEnv *env, jobject this, jint time) {
    

    

    
    if (avformat_seek_file(pFormatCtx, videoStream, 0,time,time, AVSEEK_FLAG_ANY) < 0)
    
        __android_log_print(ANDROID_LOG_DEBUG, "ERROR SEEK->>>",
    
                "av_seek_frame failed.");
    

    
    avcodec_flush_buffers(pCodecCtx);
    
}

    But the application crashes. Without avcodec_flush_buffers video seeking not correctly. How I can resolve this isssue ?
