We currently implement a WebRTC solution that accesses the video node texture using WebGL.

(e.g. GLctx.texImage2D(GLctx.TEXTURE_2D, 0, GLctx.RGBA, GLctx.RGBA, GLctx.UNSIGNED_BYTE, document.getElementById(videoNodeId););)

It appears on the surface that getting access to the underlying texture of the video object used by the Temasys WebRTC object would not be possible.

Can you please confirm this and if so offer any suggestions based on your knowledge of the technology?

Thank you.

Hi,

The rendering is indeed managed entirely by the plugin and isn't really available from the outside world.

The best you can look at is <object>.getFrame(), where <object> is the plugin renderer in the DOM.

getFrame returns the latest frame, in a base64 encoded BMP format.

See the following links on Safari/IE for examples :

Regards,
