  • Warning "i686-mingw32-pkg-config not found, library detection may fail" while cross compiling ffmpeg

    12 octobre 2015, par S B

    I get the following warning while trying to cross compile ffmpeg as below

    $ ./configure --enable-gpl --enable-version3 --enable-libgsm --enable-libvorbis --enable-libtheora --enable-libspeex --enable-libmp3lame --enable-libopenjpeg --enable-libopencore_amrwb --enable-libopencore_amrnb --arch=x86 --enable-runtime-cpudetect --enable-static --disable-shared --enable-libxvid --enable-libx264 --target-os=mingw32 --enable-avisynth --enable-w32threads --cross-prefix=i686-mingw32- --cc='i686-mingw32-gcc' --enable-memalign-hack --disable-doc --enable-avfilter --disable-ffplay --disable-ffserver --disable-ffprobe

    Configure ran fine but with the following warning

    License: GPL version 3 or later
    Creating config.mak and config.h...
    libavutil/avconfig.h is unchanged

    WARNING: i686-mingw32-pkg-config not found, library detection may fail.

    How do I provide i686-mingw32-pkg-config to configure ?

  • For WMV files avformat_find_stream_info() shows "Extra data : 8 bits left, value : 0" message

    15 avril 2013, par Mike

    When I call avformat_find_stream_info() for wmv files, the following message is always seen :
    [wmv3 00FAEAE0] Extra data : 8 bits left, value : 0

    After that the program works as expected but anyway I would like to know what does that message mean ? Thank you !

    File info (by ffmpeg -i) :

    Duration: 00:00:06.92, start: 0.000000, bitrate: 1514 kb/s
    Stream #0:0(rus): Audio: wmav2 (a[1][0][0] / 0x0161), 44100 Hz, stereo, fltp, 128 kb/s
    Stream #0:1(rus): Video: wmv3 (Main) (WMV3 / 0x33564D57), yuv420p, 720x576, 1368 kb/s, SAR 16:15 DAR 4:3, 25 tbr, 1k tbn, 1k tbc

    Code :

    AVFormatContext*    pFormatCtx = avformat_alloc_context();
    if (avformat_open_input(&pFormatCtx, "file.wmv", NULL, NULL) < 0)
       return 0;
    if (avformat_find_stream_info(pFormatCtx, NULL) < 0) // HERE WE HAVE GOT THAT MESSAGE
       return 0;
  • ffmpeg avformat_open_input always returns "Protocol not found" rv=(-1330794744)

    4 septembre 2013, par bzivkovic

    Trying to get ffmpeg working in Visual Studio 2010. So far all ffmpeg headers and libs are loaded, no error or warning occurs.

    avcodec_register_all();
    AVFormatContext *pFormatCtx = NULL;
    char errbuf[256];
    pFormatCtx = avformat_alloc_context();
    int rv = avformat_open_input(&pFormatCtx, "myfile.ext", NULL, NULL);
    if (rv!=0){                              
       av_strerror(rv, errbuf, sizeof(errbuf));
    }

    The problem is, avformat_open_input always returning -1330794744 (errbuf="Protocol not found"). Tried x86 & x64 headers and libs on 32bit XP and 64bit W7. Whatever I put for "myfile.ext" (tried "file1.avi", "file=c :\file1.avi", "http://www.someweb.com/file1.avi", and even empty char* "") response is always "Protocol not found". Any ideas ?
