Presence is a small - but yet flexible - tool to do simple and high-quality streaming (using dirac+vorbis over RTP) in a local broadcast domain.
When not using the MDNS feature this can also be endpoints on any routable network.
Not shown on in the screen shot, but a feature, is picture-in-picture mode for secondary streams.
Anyhow, this new release (0.4.8) contains an improvement related to publishing a stream. It's now done in two clicks with reasonable defaults, even for low-end machines.
Install or update it now on Fedora 16/17/18:
$ sudo yum clean metadata $ sudo yum install --enablerepo=updates-testing presence # or $ sudo yum update --enablerepo=updates-testing presence
Or - hero-like -using this one-click technology.
The release was motivated by my new Logitech HD Pro Webcam C920 which is working out of the box on Fedora - so YUV and MJPEG besides the (unsupported) h.264 support.
When looking at the video quality of this camera and two built-in cameras of laptops, this is clearly a big step forward in image quality - So a decent camera is always a good way to improve a video conference.
As said, the video quality is great - and using MJPEG it can deliver a 720p video with up to 24fps, so ideal for telepresence.
Thank you for the post. I tried this on my F18 box and it core dumped.ReplyDelete

hey chida, thanks for this report. I only tried it on F16 and F17 but will look into this issue. You might want to add a bug report if you want to make sure that I don't forget about it :)Delete
Sorry! Correction: I tried it on my F17 box and not F18. I tried multiple combinations of resolution and FPS and they all core dump. I can open a bug report but where :)Delete
Ah okay, well that is not intended :)Delete
Please file it here. Thanks
