    random_seed : Support using CryptGenRandom on windows

  • how can I use the openCV FFMPEG video I/O rather than the DirectShow one in Windows ?

    2 mai 2012, par octi

    So I'm trying to write a video using the openCV videoWriter as such :

    writer=cv.CreateVideoWriter(path+"test_output.avi",-1,fps,(W,H),1)

    So instead of supplying the FOURCC I supplied -1 in order to see what codecs I have available.
    Result was Microsoft RLE, Microsoft Video 1, Intel YUV, and Uncompressed.

    The reason is that when configuring openCV using CMAKE for Visual Studio 10 x64, this is what I have in the video i/o :
    Video I/O : DirectShow

    Is there a way to switch this to FFMPEG ? I know the ffmpeg dll is present in \3dparty\ffmpeg.
    I looked for Cmake FFMPEG flags but found none whatsoever. The weird thing is in the CmakeLists.txt in the opencv root under the video section :

    if(UNIX AND NOT APPLE)
    <ffmpeg stuff="stuff">
    elseif(WIN32)
       status("  Video I/O:"        HAVE_VIDEOINPUT     THEN DirectShow ELSE NO)
    endif()
    </ffmpeg>

    So it seems to me that opencv automatically switched to DirectShow and gives no choice of using FFMpeg.
    Or rather can one upgrade Driectshow to support other formats such as Divx or h264 ?
    Any ideas ?

  • ffmpeg windows : how to run ffmpeg -i input -filter:v frei0r=pixeliz0r=0.02:0.02 output

    7 octobre 2015, par yarek

    I run ffmpeg on Windows.

    I try to run

    ffmpeg -i input.avi -filter:v frei0r=pixeliz0r=0.02:0.02 ouput.avi

    I have this error :

    No such filter: 'frei0r
    Error opening filters!

    When I run ffmpeg.exe I got :

    ffmpeg version git-N-30610-g1929807, Copyright (c) 2000-2011 the FFmpeg developers

    Note the --enable-frei0r above.

    Any idea where I can get the ffmpeg for windows with frei0r enabled and working ?
