Faster way to save textures

vvvv beta question
#1

I’m trying to save the rgb video output from a Kinect 2 as an image sequence.

I’m able to get around 10 fps exporting as dds to a ramdisk using Writer(DX11.Texture2d)

I’m likely getting close to the disk write speed bottleneck here, but if I write to a different format with a smaller filesize (eg jpg or png) the framerate drops significantly, implying a bottleneck in compressing the images.

Can anyone think of a way I can save these images to disk faster?

Note: I’m actually playing back this data as recordings from Kinect Studio, but as far as I know, there is no way to either extract the image data from the xef file, or slow down / manually control the playback rate from Kinect Studio.

Maybe instead of saving realtime , you can use a queue node to store the frame and then save everything later , you might not be able to save long video , but at least you’ll have good framerate and original def.

afaik there is no texture queue in dx11

#5

fraps will record uncompressed video. can’t you do this and convert to frames?

@xd I was hoping to record the RGB and depth streams simultaneously so they are syncronised, and I doubt Fraps will record a 32bit float texture.

Otherwise it shouldn’t be that hard to do a queue node…

my c sharp sux!

here is the dx11 queue: setslice-(dx11.texturearray)-(dx11)

Ah!
… no text …

@mrboni: How do you playback the recordings from Kinect Studio? Couldn’t find a node for this.

@guest - You don’t need any different nodes for it. Kinect studio just hijacks the stream and pretends to v4 that it’s live data
