VideoMaterial heavily pixelized

[Leonel]

Hi everyone,

I'm trying to make a simple video player, by using 360 degreee videos.
A small company was able to provide me a sample video to work with.
The video it's not an espherical one, so it's like a panoramic foto
but extra wide.

The video is in MP4 format and has 4594x300 pixels. First thing I did
was to convert to movie to FLV using the free SUPER converter, using
VP6 encoder instead of H264.

If I try to play the file in a normal video playback, it shows with no
problem.

Then I try to place it has a VideoMaterial in a cylinder with no caps.
The video shows, but extremely pixelated, that is the pixels are
rectangles and form stripes from top to bottom.

Are there any consideration regarding the size of the cylinder, the
camera placement, or the movie encoding?

A sample image is available here: http://www.pic2up.net/view/YOVJWhN

I think that this is a simple issue, because I looked in forums and
tutorials, and didn't find a similar problem. Certainly I'm missing
something. I'm not experineced in 3D in Actionscript.

Thanks for the help,
Leonel

fixedWidth and fixedHeight = video size, otherwize default 340x2 something is applied
assuming here you do use 3.6

Thanks for your help Fabrice,

I tried to make some sense out of what you said, and it seems logical.
But now that I digged deeper into understanding the VideoMaterial
class, fixedWidth and fixedHeight are private properties, and are
initialized when the video is loaded.

Although if I trace the width and height of the video material it
returns the value 1 for each. With a VideoEvent.METADATA event it
returns the the correct size(4594x300).

I used earlier the 3.6 version, but now I'm using the trunk version,
but the result is the same.

How can I achieve the matching of the values, since there's no direct
method to do it?

My code looks like this:

var videoMat:VideoMaterial = new VideoMaterial();
videoMat.addEventListener(VideoEvent.METADATA, onMetaData);
videoMat.file = "dados/Video360_mostra.flv";
videoMat.interactive = false;
videoMat.loop = false;
videoMat.volume = 0.5;

cylinder = new Cylinder( { material:videoMat, segmentsH:1, segmentsW:
30, height:300, radius:100, openEnded:true } );
cylinder.scaleX = -1;
view.scene.addChild(cylinder);

Thanks for your time,
Leonel

thats because I did this 3.6 update in a rush.
just pass {fixedWidth:val, fixedHeight:val} in your VideoMaterial constructor

I'll try to add the setters asap.

Note that I'm also about to release a software for this...

Thanks for the help Fabrice, it's working perfectly now :)

I've been looking at Sfeerz with a little help from Google, and I must
say that's a promising and impressive application.

Will it be a commercial application? When do you think it will be
available?
