  • Redirect FFMPEG's output to multiple named pipes on Windows

    31 mai 2016, par tearvisus

    I am trying to stream video and audio data into two separate named pipes on Windows.

    ffmpeg.exe -f dshow -i video="My camera name":audio="My microphone name" -map 0:1 -ac 1 -f f32le \\.\pipe\audioStream -map 0:0 -f mjpeg \\.\pipe\videoStream

    The problem is that FFMPEG does not seem to understand that the outputs \\.\pipe\audioStream and \\.\pipe\videoStream are pipes and treats them like files.

    1. If the pipes are already created when the FFMPEG starts, it wants to overwrite them and fails.
    2. Otherwise, it complains that the path does not exist and fails.

    As far as I understand, specifying the pipe: protocol should do the trick, but I can’t figure out how to use it properly, even with a single pipe. I have tried :

    1. pipe:pipeName
    2. pipe:pipe\pipeName
    3. pipe:\\.\pipe\pipeName
    4. pipe://pipeName
    5. pipe://pipe\pipeName
    6. pipe://\\.\pipe\pipeName

    I always end up with the same result : the output is written to the console and not to the pipe. If the pipe already exists when the FFMPEG starts, nothing connects to the pipe.

    Is it possible to use FFMPEG with named pipes on Windows ? If yes, what is the proper way to do this ?

  • how to choose a screen to capture with ffmpeg in qt on windows

    13 octobre 2020, par YouCL

    I am using qt with ffmpeg to record desktop on windows. My question is : if I have multiple screens, how to control the recording target ?

    


    Now I pass desktop to param url in function int avformat_open_input(AVFormatContext **ps, const char *url, AVInputFormat *fmt, AVDictionary **options); . Is there some other param form for url to control which screen to capture ?

    


    For example, if I only want to record the primary screen, what url value should I use ?

    


    I know qt can identify primary screen and other screens. Is there a way to pass the screen id to ffmpeg ?
