Introducing Gmerlin recorder

Gmerlin-recorder is a small application, which records audio and video from hardware devices. It was written as a more generic application, which should eventually replace camelot. See below for a screenshot:

As sources, we support:
  • Audio devices via OSS, Alsa, Esound, Pulseaudio and Jack
  • Webcams via V4L and V4L2
  • X11 grabbing
For monitoring you see the video image in the recorder window. For the audio you have a vumeter. With recorded streams you can do lots of stuff:
  • Filter the streams using gmerlin A/V filters
  • Write the streams to files using gmerlin encoder plugins
  • Send the encoded stream to an icecast server (will be described in detail in another blog post)
  • Save snapshots to images either manually or automatically
With all these features combined in the right way, you can use gmerlin-recorder for a large number of applications:
  • Make vlogs with your webcam and a microphone
  • Digitize analog music
  • Make a video tutorial for your application
  • Start your broadcasting station
  • Send music from your stereo to your WLAN radio
  • Make stop-motion movies
  • ...
Until the recorder can fully replace camelot, we need the following features, which are not there yet:
  • Fullscreen video display
  • Forwarding of the video stream via vloopback

Great job for publishing such a beneficial web site. Your web log isn’t only useful but it is additionally really creative too. There tend to be not many people who can certainly write not so simple posts that artistically. Continue the nice writing call recorder
