  • Use Windows ffmpeg to record audio output without using the StereoMix

    2 septembre 2016, par DevtelSoftware

    I am looking for a way to record the audio output (speakers) using Windows ffmpeg.
    I need to do this WITHOUT installing any extra dshow filters and without having the StereoMix input enabled (since this is not available on many computers).

    I have read in the ffmpeg documentation that the -map would allow redirecting an audio output so that ffmpeg sees it as an audio input but I can’t find any example of how to do that.

    In Linux I managed to do it like this :

    ffmpeg -f pulse -ac 2 -ar 44100 -i alsa_output.pci-0000_00_1f.4.analog-stereo.monitor -f pulse -ac 2 -ar 44100 -i alsa_input.pci-0000_00_1f.4.analog-stereo -filter_complex amix=inputs=2 test.mp4

    However I can’t find a similar way to do it in Windows and MacOSX.

    So in short, is it possible with the Windows ffmpeg to record audio from the speakers without extra dshow filters (out-of-the-box) ? Same question goes for MacOSX.

    Thanks !

  • FFmpeg file size while recording multiple windows at same time

    29 août 2021, par RuanS

    I'm currently recording 3 windows at once, and placing them next to each other, windows dimensions are : 400x500, 830x500, 830x500, using -c:v h264_nvenc to reduce the use of CPU.

    


    The first and second windows have very low frames change, the third window does change frames frequently.

    


    ffmpeg -f gdigrab -framerate 30 -i title="" -f gdigrab -framerate 30 -i title="" -f gdigrab -framerate 30 -i title="" -c:v h264_nvenc -qp 0 -c:a copy -vsync vfr -filter_complex hstack=inputs=3 output.mp4


    


    Doesn't need to be great quality, 'normal/medium' quality is enough, also, I'm recording only video, no audio.

    


    After 3min the file size was over 340MB, would like to ask if there are any better options in which I could be used to reduce the file size also CPU use (if possible).
