Struct gstreamer_gl::GLBaseFilter [−][src]
pub struct GLBaseFilter(_);
crate::GLBaseFilter handles the nitty gritty details of retrieving an OpenGL
context. It also provided some wrappers around crate::gst_base::BaseTransform’s
start(), stop() and set_caps() virtual methods that ensure an OpenGL
context is available and current in the calling thread.

pub fn set_control_binding_disabled(&self, property_name: &str, disabled: bool)[src]This function is used to disable the control bindings on a property for
some time, i.e. Self::sync_values() will do nothing for the
property. Read more
pub fn set_control_bindings_disabled(&self, disabled: bool)[src]
pub fn set_control_bindings_disabled(&self, disabled: bool)[src]This function is used to disable all controlled properties of the self for

pub fn set_control_rate(&self, control_rate: ClockTime)[src]
pub fn set_control_rate(&self, control_rate: ClockTime)[src]Change the control-rate for this self. Audio processing crate::Element
objects will use this rate to sub-divide their processing loop and call
Self::sync_values() in between. The length of the processing segment
should be up to control-rate nanoseconds. Read more

P: IsA<Object>, [src]Sets the parent of self to parent. The object’s reference count will
be incremented, and any floating reference will be removed (see [crate::Object::ref_sink()]). Read more
pub fn suggest_next_sync(&self) -> ClockTime[src]
pub fn suggest_next_sync(&self) -> ClockTime[src]Returns a suggestion for timestamps where buffers should be split to get best controller results. Read more
