  • How to compile ffmpeg.c and its dependencies code in Eclipse ?

    15 juillet 2013, par user1914692

    Since there is very limited number of ffmpeg examples, I want to know ffmpeg better through debugging ffmpeg process.

    So with the downloaded ffmpeg code, I hope to only compile ffmpeg.c (has a main function) with its dependences in Eclipse.

    But when I put the source in a project of Eclipse, it put out errors as :
    ‘F_NOCACHE’ undeclared (first use in this function) yuvcmp.c /ffmpegTest/src/tools line 63 C/C++ Problem

    I failed to find information about F_NOCACHE.
    Where and how to set its value ?

  • Recording a mp3 stream with FFMPEG and drop-outs

    14 mars 2013, par Rob Oliver

    I hope someone can give me pointer, I have a php script that runs the command below to record an live radio mp3 stream to create hour long mp3 recordings. It works very well for my purpose. The only issue is occasionally no recording is made. As far as I can tell its because the stream has dropped out and ffmpeg just aborts.

    /usr/local/bin/ffmpeg -i http://www.mystream.com:8000/radiostream.mp3 -t 60:00 -acodec copy /var/www/mydomain/audio/".$recorded_audio_title;

    So my question, is there anyway to tell ffmpeg to continuously record for the 60:00 minutes to make a recording even if their are drop outs ? I'd be happy with a odd bit of silence providing it completed the recording.

    I hope this makes sense and I'd appreciate even a pointer to a FFMPEG option or flag. Having Google'd I havnt seen anything that would fit the bill.

    Many thanks in advance

  • How to capture camera devices on Windows using Libav ?

    22 septembre 2011, par Occulta

    Is there any way to capture frames from as many camera types as DirectShow do on Windows platform using Libav ? I need to capture a camera output without using DirectShow filters and I want my application to work with many camera devices types.

    I have searched the Internet about this capability of libav and found that it can be done via libav using special input format "vfwcap". Something like that (don't sure about code correctness - I wrote it by myself) :

    AVFormatParameters formatParams = NULL;
    AVInputFormat* pInfmt = NULL;
    pInFormatCtx*  pInFormatCtx = NULL;

    av_register_all();

    //formatParams.device = NULL; //this was probably deprecated and then removed
    formatParams.channel = 0;
    formatParams.standard = "ntsc"; //deprecated too but still available
    formatParams.width = 640;
    formatParams.height = 480;
    formatParams.time_base.num = 1000;
    formatParams.time_base.den = 30000; //so we want 30000/1000 = 30 frames per second
    formatParams.prealloced_context = 0;


    pInfmt = av_find_input_format("vfwcap");
    if( !pInfmt )
    {
     fprintf(stderr,"Unknown input format\n");
     return -1;
    }

    // Open video file (formatParams can be NULL for autodetecting probably)
    if (av_open_input_file(&pInFormatCtx, 0, pInfmt, 0, formatParams) < 0)
      return -1; // Couldn't open device

    /* Same as video4linux code*/

    So another question is : how many devices are supported by Libav ? All I have found about capture cameras output with libav on windows is advice to use DirectShow for this purpose because libav supports too few devices. Maybe situation has already changed now and it does support enough devices to use it in production applications ?

    If this isn't possible.. Well I hope my question won't be useless and this composed from different sources piece of code will help someone interested in this theme 'coz there are really too few information about it in the whole internet.
