Why is VideoTexture displaying my camera and flv streams as partially transparent?

Question

When using VideoTexture my camera and flv streams are being rendered as partially transparent. This issue is intermittent. When using a Logitech c920 camera the VideoTexture seems to be rendering all pixels as expected. But with an Axis P12 camera, the pixels are always transparent (on Windows 8). When using .flv stream from RTMP server, the decoded pixels are sometimes rendered as transparent, and other times fully opaque. This behavior is also interesting when taking iOS 8 and iPhone 6 into account. So I play a flv stream on Windows and it is partially transparent. But then deploying the same code to iPhone 6, the flv stream renders fully opaque as expected.

Is the VideoTexture engineering team already aware of this?

Is Adobe's focus really on "Premium Video" and Gaming or Stage3D? If video is supposed to be a focus, why can't we get some attention to video such as this bug?? The sample app is not crashing. I have tried the attached version, as well as using the latest AIR 19 SDK and unfortunately still no proper video using VideoTexture on iOS.

For me VideoTexture works fine with camera.

May be you use blending? Something like:

context3D.setBlendFactors(Context3DBlendFactor.ONE, Context3DBlendFactor.ONE);

With this blending I also see streams partially transparent, but it's only one way I found to display FLV video with alpha channel.

If I use

context3D.setBlendFactors(Context3DBlendFactor.ONE, Context3DBlendFactor.ZERO);

stream fully opaque.

I have test it only with Windows for now.
