  • Running ffmpeg from a windows service on same machine encounters permissions issue

    8 mars 2012, par gaijintendo

    I had been running a Windows Service, form my machine (which has full read/write access to a network drive).

    The command for ffmpeg was something like this :
    - i \filestore\test.avi -b 500000 -s 640x360 -ar 22050 -copyts -y -vcodec libx264 -acodec ac3 -y \filestore\mp4\test.mp4

    Running it from cmd works perfectly. Running it from a windows service, from the same machine, would yield a File Not found type error. Updating to the latest ffmpeg stable changed that to "Permission denied".

    I am running the service it as 'Local Account'. I was intending to run this on another server, so I need to get a grip on this !

    Does running a service on your machine run as a different user to you when you choose 'Local Account' ?

  • 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 ?
