  • Command-line streaming webcam with audio from Ubuntu server in WebM format

    28 avril 2017, par mjtb

    I am trying to stream video and audio from my webcam connected to my headless Ubuntu server (running Maverick 10.10). I want to be able to stream in WebM format (VP8 video + OGG). Bandwidth is limited, and so the stream must be below 1Mbps.

    I have tried using FFmpeg. I am able to record WebM video from the webcam with the following :

    ffmpeg -s 640x360 \
    
-f video4linux2 -i /dev/video0 -isync -vcodec libvpx -vb 768000 -r 10 -vsync 1 \
    
-f alsa -ac 1 -i hw:1,0 -acodec libvorbis -ab 32000 -ar 11025 \
    
-f webm /var/www/telemed/test.webm

    However despite experimenting with all manner of vsync and async options, I can either get out of sync audio, or Benny Hill style fast-forward video with matching fast audio. I have also been unable to get this actually working with ffserver (by replacing the test.webm path and filename with the relevant feed filename).

    The objective is to get a live, audio + video feed which is viewable in a modern browser, in a tight bandwidth, using only open-source components. (None of that MP3 format legal chaff)

    My questions are therefore :
    How would you go about streaming webm from a webcam via Linux with in-sync audio ? What software you use ?

    Have you succeeded in encoding webm from a webcam with in-sync audio via FFmpeg ? If so, what command did you issue ?

    Is it worth persevering with FFmpeg + FFserver, or are there other more suitable command-line tools around (e.g. VLC which doesn’t seem too well built for encoding) ?

    Is something like Gstreamer + flumotion configurable from the command line ? If so, where do I find command line documentation because flumotion doc is rather light on command line details ?

    Thanks in advance !

  • Convert videos to webm via ffmpeg faster

    17 octobre 2016, par Rocky Singh

    I am using the following params via ffmpeg to convert videos to webm format :

    -c:v libvpx -qmin 0 -qmax 50 -crf 4 -b:v 2M -c:a libvorbis -q:a 10

    However it takes lot of time (more than 5 minutes) just to convert 5 MB video. Can I write some other params to make the conversion fast ?
