  • ffmpeg watermarking error : video pixel format unknown, Parser not found for codec

    13 décembre 2011, par Sunil

    I am trying to watermark my video but I am getting pixel format and codec errors.

    I am using latest version of FFmpeg git-7d531e8 64-bit Static (Latest) (2011-12-12) from link http://ffmpeg.zeranoe.com/builds/

    I am using the below code to add watermark to my video.

    ffmpeg -i inputputfile.avi -target pal-vcd "movie=abc.png [Watermark] ; [in][Watermark] overlay=10:10 [out]" outputfile.avi.

    But i am receiving the error of video pixel format unknown and parser not found for codec error.

    Later, I changed by code to add codec and pixel format.

    ffmpeg -i inputputfile.avi -vcodec wmv3 -pxl_fmt yuv420p -target pal-vcd "movie=abc.png [Watermark] ; [in][Watermark] overlay=10:10 [out]" outputfile.avi.

    However I am still receiving the same error. Please help.

  • 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.

  • video conversion using ffmpeg in php

    24 mars 2012, par user1270879

    I am converting videos to .flv format using ffmpeg in php. The files are converted into .flv but the size of the file 0 kb. What is the reason ?

    My code

    $ffmpegPath = "/usr/bin/ffmpeg";
    
$flvtool2Path = "/usr/bin/flvtool2";
    

    
$cmd=($ffmpegPath . " -i " . $srcFile . " -ar " . $srcAR . " -ab " . $srcAB . " -f flv -s " . $srcWidth . "x" . $srcHeight . " " . $destFile . " | " . $flvtool2Path . " -U stdin " . $destFile);
