If LiVES has to import first, then the feature of taking live streams was just another way to import a video file. That is not what I was talking about. As far as I know, we are not shipping kdenlive this cycle, though it has been made easier to install. I don't get the idea it does live video switching/fading either. By live switching I mean having two or more video streams coming in direct from cameras for example and being able to see both streams at the same time as well as the result of the switching (that is at least three live views)... probably four to include at least one stream from the local drive. The resultant video is then output as video that can be broadcast at the same time the incoming video is being made. Bonus if the audio can be mixed on the same machine. or at least added to the stream. Anything less is editing/VJing. The thing that I am trying to say however, is that I don't think we need to worry about finding an app that does that. That kind of work really can't be done solo. It requires a team of people. A min. of 4 if the switcher can produce as well, but still need two for camera and one for audio. I suppose one could get away with two people if one camera is stationary and the audio is set a little low and there is no need to transition audio streams. In my opinion the result would be sub-standard. Normally, seven people would be used. (even at a place that skimps on _everything_) The only place I see this being used is in a live setting for filling large screens behind or to the side of a stage where it was important to show the performer. We would be getting into specialty work... a very small group of people and a set of apps we probably can't test on any of our HW. (anyone have at least a dual video input card as well as video out?) My machine has trouble giving smooth video from a cheap webcam... and the video out is way lagged behind the input. I think live video work would require getting rid of X and handling the video directly with a video version of jackd. I think there is a reason it is hard to find software that can do this stuff, not enough people want it or the hardware is just not there yet. I did find a thread where someone was looking for such stuff, the responses were all that it was better to get hardware, that any of the software solutions showed noticeable lag. So computers have gotten faster, but they are still not there yet. -- Len Ovens www.OvenWerks.net -- Ubuntu-Studio-devel mailing list Ubuntu-Studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
