Hdtv jpg sequences

vvvv beta general

hi,

as i don`t really use vvvv a lot this is just a basic question (well just a performance question(s)).

  1. is there an object for playing jpg sequences?
  2. if there is such an object, does it profit of “boygrouping”
    and 3. may there be the possibillity to use such a boygrouping system to play jpg sequences in hdtv resolution (1920x1080)

any hints or tips are needed
regards

1.)

you may easily patch something like this:

(2) yes. all nodes can benefit from boygrouping.
if you select Quad, Scale, Filetexture and the Renderer and press Ctrl+B you can easily boygroup the image generating parts - all machines in the boygroup will have these nodes. the image will appear directly on all machines. how to setup your multi screen world is up to you - possible next steps would be shifting the texture or selecting different textures depending on the clientid of each machine.

note that the boygrouping doesnt copy your image files (yet) - you might like to have them on a shared volume on the server. or (advanced) boygroup a shellexecute node, which copies the data from the aforementioned shared volume to a local disc drive.

(3) jpg sequences get loaded into the video cards ram - so as long as you can load all images of your movie into the grahics card you can almost do anything at full frame rates with any recent graphics card. play jpg loops, smooth cross dissolves, layerings, image warping, pixel shader effectes. etc.

if your movie is longer you´d better use avi files for playing. avi files are always streamed from disk, so playback quality is bound to processor and harddisc speeds.
