Hi,
Does anyone know the easiest way of combining 2 or more camera outputs into one stream? ie. how can I take two cameras using 320 x 240 and generate a wider image 640x240? Is this possible in PD? I would like the resulting stream to be available in v4l ie /dev/video0 + /dev/video1 = /dev/video2 . Any thoughts on this? Thanks, Jim

If I have two images coming out from two [#in], I can make a wider image that contains both images side to side using [#join 1], but this is not the only way of putting images together to form a bigger image. for example, it could be about alternating slices of both images. In that case, I'd use a [#remap_image] after the [#join 1], to shuffle things around a bit.
But you didn't say whether you want to do this with GEM, PDP or GF.

I don't see how you could make the result available as a v4l device without doing things in C, and even then I would not know how to make it work.
Certainly not possible directly in PD without making your own v4l output external. I guess there is no such thing? (vloopback?)

ola,
easy to get the input of two cams and make a composite in pdp, gem or gf ...
but i don't know any code that outputs this as in a v4l [virtual] device ... where do you want to use the output ???
we usually get such an putput with video outpit, wires and a mixer .. cos the machine would be overloaded quite fast ..

I wanted to use it with CCV http://ccv.nuigroup.com/

Ok Thanks a lot. If I find another way or write something I'll let folks know. It seems an external that takes Gem, PDP, etc. output and sends it to vloopback could be quite useful for working with other programs.

Hi Jim,
there is this one project , called VideoJack, started by Jaromil I guess, might be a starting point... if you can portuguese!

You could stream the video result.... at least I think you can do it easily

ola,
it was not started by jaromil, but by the collective that gather every year in piksel and one which work much in this is salsaman from LiVes..
why do you need always to put one author on a collective project?
i never participated myself on the pd-side, cause i never use 2 video applications at the same time on a single machine, i don't think you can really work this way

Thanks a lot Oliver. Yes looks like an interesting project. I'll look into adapting it.

adapt it?? you mean write some externals in pd?
anyway the real page of Video Jack is here : http://www.piksel.no/pwiki/VideoJack

I used videojack with EffectTV and piped it into pd with video jack externals would be nice for this.

afaik there is an experimental vloopback module for GStreamer available.
you could use pdgst to control it from within Pd (if you don't want to
use GStreamer directly)
