Does anyone have an example of a shader for a RoQ video gui in Q4? I have a D3 shader, but it doesn't perform as expected, and I'm not sure how similar they are to an equivalent Q4 RoQ video shader. If I knew the required parameters I could figure out what's going on.

Any help is much appreciated.

I used to have one for D3. I'm surprised there is any difference.

I'm thinking maybe it's my creation of the RoQ that's the issue. I'm using Quake Video Maker to convert AVI to RoQ. When I start a new project and import the AVI, and even when I create the RoQ, I get a black screen for the preview. I don't know if this is what's previewing or if it's not advancing any frames. Within my mod the video gui also shows black.

Any suggestions? I'm following the QVM instructions, but they are sparse. Is there any special AVI format I must have to convert to RoQ? I'm creating a 512x384 30fps RoQ. At least the RoQ file is generated, but I have no way to validate if it's viewable.

Here are some specifics that may help unravel this:

I have the following files

q4base\materials\mymaterials.mtr
q4base\guis\movies\fusion.gui
q4base\sound\VO\video\custom\fusion.roq

Here's the material file shader code

video/fusion 
{ 
videomap loop sound/VO/video/custom/fusion.roq 
} 

Here's the gui code

windowDef Desktop
{
	rect	0,0,640,480
	windowDef Videofeed
	{
		rect	0,0,640,480
		visible	1
		forecolor	1,1,1,1
		text	VideoFeed
		textscale	1
		background	""
		backcolor	0,0.250,0.501,1
		matcolor	1,1,1,1
	}
	windowDef RoQfile
	{
		rect	65,50,512,384
		visible	1
		background	"video/fusion"
		backcolor	0,0,0.501,1
		matcolor	1,1,1,1
	}
}

Hope this helps...

In addition, I solved the preview issue and the RoQ creation with Quake Video maker. I reencoded the source AVI to be 512x384 at 24fps and Indeo codec, and QVM liked that a lot better.

However, I'm not getting the video playing in my in-game gui.

Any suggestions?

I would have recommended the quake video maker. The rest should be working. I am going to have to test this out myself this afternoon.

I think the problem is your video size.
- Roq file dimensions MUST be a power of 2 (128x128, 256x256, 512x512)

I keep getting "bad size, must be 512 by 384" error from QVM. Doesn't seem to let me use another video size for RoQ output. This is independent of the input AVI size, as I tried converting from a 512 x 512 AVI, in case there was an issue with scaling.

Any ideas?

I see. The problem is that you can't use QVM. That's for older versions.

You need to try this:

- Make sure you AVI is square and power of two (128x128, 256x256, 512x512)

- Download VirtualDub to convert your AVI to individual TGA frames.
http://virtualdub.sourceforge.net/

- Save your audio as a wav if you have audio. I assume you don't so I am skipping that.

- as for the ROQ tool, use ROQ Video Compiler
http://www.modsonline.com/Downloads-full-4002.html
* Extract contents anywhere
* Run RoQCreator.exe
* File > Add TGAs
* enter the RoQ file name
* Press Make RoQ
* wait a while (about 1.5 seconds per frame)

This process will create the roq file

Then follow this tutorial:

Thanks for the info Foleyman.

In the meantime, I downloaded Switchblade and though it's crude, it rendered a 512 x 512 RoQ for me (it matches whatever input AVI dims are) and the gui popped up. You were right, the non-2x size was the issue. Works great now.

Thanks for all the work on getting me an answer - much appreciated. I'll certainly go through it to refine my video guis.
