  • Need to get audio video structure for automation ffmpeg or ffprobe

    10 mai 2012, par Sapan Doshi

    I need to get video audio stream information in separate form.

    I have tried ffprobe and mediainfo, but they give full information which needs to be parsed.

    I think there could be option like, where I do not need to parse the full information and get required data.

    $ffprobe -XXX
    audio channels 8

    $ffprobe -YYY
    video_resolution 512x288

    Can anybody help with this.

  • How to encode video using ffmpeg-java on Android from Bitmaps ?

    15 décembre 2011, par gtcompscientist

    I am using ffmpeg-java compiled for Android to encode/decode video for my application.

    The problem that I've run into is that I am currently getting each frame as a Bitmap (just a plain android.graphics.Bitmap) and I can't figure out how to stuff that into the encoder.

    Here is the code that I am using to instantiate all the ffmpeg libraries :

        AVCodecLibrary cLibrary = AVCodecLibrary.INSTANCE;
    
    cLibrary.avcodec_register_all();
    
    cLibrary.avcodec_init();
    

    
    AVFormatLibrary fLibrary = AVFormatLibrary.INSTANCE;
    
    fLibrary.av_register_all();
    

    
    //AVUtilLibrary uLibrary = AVUtilLibrary.INSTANCE;
    
    //uLibrary.av_malloc();
    

    
    AVCodec pCodec = cLibrary.avcodec_find_encoder(AVCodecLibrary.CODEC_ID_H263);
    
    if (pCodec == null)
    
    {
    
        Logging.Log("Unable to find codec.");
    
        return;
    
    }
    
    Logging.Log("Found codec.");
    

    

    
    AVCodecContext codecCtx = cLibrary.avcodec_alloc_context();
    
    codecCtx.bit_rate = 64000;
    
    codecCtx.coded_width = VIDEO_WIDTH;
    
    codecCtx.coded_height = VIDEO_HEIGHT;
    
    codecCtx.time_base = new AVRational(1, VIDEO_FPS);
    
    codecCtx.pix_fmt = AVCodecLibrary.PIX_FMT_YUV420P;
    
    codecCtx.codec_id = AVCodecLibrary.CODEC_ID_H263;
    
    //codecCtx.codec_type = AVMEDIA_TYPE_VIDEO;
    

    
    if (cLibrary.avcodec_open(codecCtx, pCodec) < 0)
    
    {
    
        Logging.Log("Unable to open codec.");
    
        return;
    
    }
    
    Logging.Log("Codec opened.");

    This is what I want to be able to execute next :

    cLibrary.avcodec_encode_video(codecCtx, pPointer, pFrame.size(), pFrame);

    But, as of now, I don't know how to put the Bitmap into the right piece or if I have that setup correctly.

    A few notes about the code :
    - VIDEO_WIDTH = 352
    - VIDEO_HEIGHT = 288
    - VIDEO_FPS = 30 ;
    - I'm unsure about how pPointer and pFrame are handled.

  • ffmpeg : add hyperlink to video ?

    15 mars 2012, par Simon

    i am experiment with ffmpeg, making videos from more images and adding watermark, some effect etc.

    What I am interested : Is it possible to embed HYPERLINK into video using ffmpeg ?

    For example, watermark or something else to be 'clickable' and to redirect to some www location ?
