VideoSurface

A surface that allocates a video media track to use as texture Send frames like this

app:scheduleAction(0.02, true, function()
  if surface and surface.trackId then
    app.client.client:send_video(surface.trackId, pixeldata, width, height, [format=rgba8], [stride=width])
  end
end)

Constructor

Initiate a video surface.

A video track will be allocated for the surface. The resolution can not be changed later.

Arguments

Name	Type	Description
bounds	Bounds	The position and size of the surface
resolution	Table	A table ({int, int}) with width and height giving the pixel resolution of the video. Must match the width and height sent to `sendFrame`

Returns

Nothing

Methods

videosurface:setResolution (width, height)

Set the input video resolution. Must be called before awakened.

Arguments

Name	Type	Description
width	???
height	???

Returns

Nothing

videosurface:setVideoFormat (fmt)

Set the output video encoder format. Default “mjpeg” which is slow but compatible. You can also set it to “h264” if you provide liballonet-av, libavcodec etc.

Arguments

Name	Type	Description
fmt	???

Returns

Nothing

videosurface:sendFrame (pixels, width, height, format, stride)

Send a video frame to the server

Arguments

Name	Type	Description
pixels	String	with pixel data according to format and stride
width	int	The number of pixels in width. Should match the width set at init.
height	int	The number of pixels in height. Shold match the height set at init.
format	string	The pixel format. For example “bgrx8”. Default: “rgba”
stride	int	The number of bytes for each row of pixels. Default: width*bpp

Returns

Nothing
