  • capture DV video and audio with ffmpeg and dshow

    18 novembre 2016, par andrixnet

    Trying to capture video and audio from a DV camera, using ffmpeg, I got into a problem.
    Before anything, I first tried to see (and hear) with ffplay.

    I can use VLC with "Capture device" as input, selecting "Microsoft DV Camera and VCR" as video device and leaving "Default" as audio device and I get both video and audio.

    With ffmpeg I get only video stream, no audio.

    C:\>ffplay -hide_banner -f dshow -i video="Microsoft DV Camera and VCR"
    
Input #0, dshow, from 'video=Microsoft DV Camera and VCR':B f=0/0

    I don’t know how to tell ffmpeg the equivalent of "Default" audio device as VLC recognizes it.

    Device options show there are 2 pins for video device (DV device has both video and audio) but how can I tell ffmpeg such that it captures both video and audio ?

  • Rsync a video stream continously and watch it

    13 juin 2017, par Ural

    I am recording a cam on a remote machine in my office. I use ffmpeg for that, and writing to mpegts file.
    I want to copy that stream locally, to have a fresh copy, and watch it simultaneously.
    I don’t know options for rsync to grab a changing (appending) file, so I am using loop for it, and it is very slow.

    while true; do rsync -avz --progress --partial --append remote:~/myvideo.mp4 ~/; done

    For watching, I tried :

    mkfifo /tmp/fifo
    
tail -f ~/myvideo.mp4 > /tmp/fifo
    
mplayer /tmp/fifo

    But because rsync is stopping every 5 sec, it is working unstable.

    How to record and stream a remote cam continuously, and use only one network stream for that ?
