GstGL.GLFilter.prototype.draw_fullscreen_quad

function GstGL.GLFilter.prototype.draw_fullscreen_quad(): {
    // javascript wrapper for 'gst_gl_filter_draw_fullscreen_quad'
}

Render a fullscreen quad using the current GL state. The only GL state this modifies is the necessary vertex/index buffers and, if necessary, a Vertex Array Object for drawing a fullscreen quad. Framebuffer state, any shaders, viewport state, etc must be setup by the caller.

GstGL.GLFilter.prototype.filter_texture

function GstGL.GLFilter.prototype.filter_texture(input: Gst.Buffer, output: Gst.Buffer): {
    // javascript wrapper for 'gst_gl_filter_filter_texture'
}

Calls filter_texture vfunc with correctly mapped GstGL.GLMemory

GstGL.GLFilter.prototype.render_to_target

function GstGL.GLFilter.prototype.render_to_target(input: GstGL.GLMemory, output: GstGL.GLMemory, func: GstGL.GLFilterRenderFunc, data: Object): {
    // javascript wrapper for 'gst_gl_filter_render_to_target'
}

Transforms input into output using func on through FBO.

GstGL.GLFilter.prototype.render_to_target_with_shader

function GstGL.GLFilter.prototype.render_to_target_with_shader(input: GstGL.GLMemory, output: GstGL.GLMemory, shader: GstGL.GLShader): {
    // javascript wrapper for 'gst_gl_filter_render_to_target_with_shader'
}

Transforms input into output using shader with a FBO.

GstGL.GLFilter.prototype.add_rgba_pad_templates

function GstGL.GLFilter.prototype.add_rgba_pad_templates(klass: GstGL.GLFilterClass): {
    // javascript wrapper for 'gst_gl_filter_add_rgba_pad_templates'
}

vfunc_filter

function vfunc_filter(filter: GstGL.GLFilter, inbuf: Gst.Buffer, outbuf: Gst.Buffer): {
    // javascript implementation of the 'filter' virtual method
}

perform operations on the input and output buffers. In general, you should avoid using this method if at all possible. One valid use-case for using this is keeping previous buffers for future calculations. Note: If filter exists, then filter_texture is not run

vfunc_filter_texture

function vfunc_filter_texture(filter: GstGL.GLFilter, input: GstGL.GLMemory, output: GstGL.GLMemory): {
    // javascript implementation of the 'filter_texture' virtual method
}

given in_tex, transform it into out_tex. Not used if filter exists

vfunc_init_fbo

function vfunc_init_fbo(filter: GstGL.GLFilter): {
    // javascript implementation of the 'init_fbo' virtual method
}

perform initialization when the Framebuffer object is created

vfunc_set_caps

function vfunc_set_caps(filter: GstGL.GLFilter, incaps: Gst.Caps, outcaps: Gst.Caps): {
    // javascript implementation of the 'set_caps' virtual method
}

mirror from GstBase.BaseTransform

vfunc_transform_internal_caps

function vfunc_transform_internal_caps(filter: GstGL.GLFilter, direction: Gst.PadDirection, caps: Gst.Caps, filter_caps: Gst.Caps): {
    // javascript implementation of the 'transform_internal_caps' virtual method
}

Perform sub-class specific modifications of the caps to be processed between upload on input and before download for output.

GstGL.GLFilterRenderFunc

function GstGL.GLFilterRenderFunc(filter: GstGL.GLFilter, in_tex: GstGL.GLMemory, user_data: Object): {
    // javascript wrapper for 'GstGLFilterRenderFunc'
}
