Trait Implementations
impl Sync for AppSink
[src]
impl Send for AppSink
[src]
impl ElementT for AppSink
[src]
fn as_element(&self) -> &Element
fn as_element_mut(&mut self) -> &mut Element
fn to_element(&self) -> Element
fn link(&mut self, dst: &mut ElementT) -> bool
Links this element to dest . The link must be from source to destination; the other direction will not be tried. The function looks for existing pads that aren't linked yet. It will request new pads if necessary. Such pads need to be released manually when unlinking. If multiple links are possible, only one is established. Read more
fn unlink(&mut self, dst: &mut ElementT)
Unlinks all source pads of the this element with all sink pads of the sink element to which they are linked. Read more
fn bus(&self) -> Option<Bus>
Returns the bus of the element. Note that only a Pipeline will provide a bus for the application. Read more
fn name(&self) -> String
Returns the name of the element
fn set_name(&mut self, name: &str)
Sets the name of the element
fn set_state(&mut self, state: GstState) -> GstStateChangeReturn
Sets the state of the element. This function will try to set the requested state by going through all the intermediary states and calling the class's state change function for each. Read more
fn get_state(&self, timeout: GstClockTime) -> (GstState, GstState, GstStateChangeReturn)
Gets the state of the element. Read more
unsafe fn send_event(&mut self, event: *mut GstEvent) -> bool
Sends an event to an element. If the element doesn't implement an event handler, the event will be pushed on a random linked sink pad for downstream events or a random linked source pad for upstream events. Read more
fn seek_simple(&mut self, format: GstFormat, flags: GstSeekFlags, pos: i64) -> bool
Simple API to perform a seek on the given element, meaning it just seeks to the given position relative to the start of the stream. For more complex operations like segment seeks (e.g. for looping) or changing the playback rate or seeking relative to the last configured playback segment you should use gst_element_seek(). Read more
fn seek(&mut self, rate: f64, format: GstFormat, flags: GstSeekFlags, start_type: GstSeekType, start: i64, stop_type: GstSeekType, stop: i64) -> bool
Sends a seek event to an element. See gst_event_new_seek() for the details of the parameters. The seek event is sent to the element using send_event(). Read more
fn query_duration(&self, format: GstFormat) -> Option<i64>
Queries an element (usually top-level pipeline or playbin element) for the total stream duration in nanoseconds. This query will only work once the pipeline is prerolled (i.e. reached PAUSED or PLAYING state). The application will receive an ASYNC_DONE message on the pipeline bus when that is the case. Read more
fn query_position(&self, format: GstFormat) -> Option<i64>
Queries an element (usually top-level pipeline or playbin element) for the stream position in nanoseconds. This will be a value between 0 and the stream duration (if the stream duration is known). This query will usually only work once the pipeline is prerolled (i.e. reached PAUSED or PLAYING state). The application will receive an ASYNC_DONE message on the pipeline bus when that is the case. Read more
fn duration_ns(&self) -> Option<i64>
Shortcut for query_duration with format == TIME
fn duration_s(&self) -> Option<f64>
Shortcut for query_duration with format == TIME and conversion to seconds Read more
fn position_ns(&self) -> Option<i64>
Shortcut for query_position with format == TIME
fn position_pct(&self) -> Option<f64>
Shortcut for query_position with format == TIME and conversion to pct as 0..1 Read more
fn position_s(&self) -> Option<f64>
Shortcut for query_position with format == TIME and conversion to seconds Read more
fn set_position_ns(&mut self, ns: i64) -> bool
Shortcut for seek to a ceratin position in ns
fn set_position_s(&mut self, s: f64) -> bool
Shortcut for seek to a ceratin position in secs
fn set_position_pct(&mut self, pct: f64) -> bool
Shortcut for seek to a ceratin position in pcs as 0..1
fn set_speed(&mut self, speed: f64) -> bool
Shortcut for seek to the current position but change in playback rate Read more
fn set_null_state(&mut self)
shortcut to set_state with state == NULL
fn set_ready_state(&mut self)
shortcut to set_state with state == READY
fn pause(&mut self)
shortcut to set_state with state == PAUSED
fn play(&mut self)
shortcut to set_state with state == PLAYING
fn is_paused(&self) -> bool
shortcut to query the state and returns state == PAUSED
fn is_playing(&self) -> bool
shortcut to query the state and returns state == PLAYING
fn is_null_state(&self) -> bool
shortcut to query the state and returns state == NULL
fn is_ready_state(&self) -> bool
shortcut to query the state and returns state == READY
unsafe fn gst_element(&self) -> *const GstElement
Returns a const raw pointer to the internal GstElement
unsafe fn gst_element_mut(&mut self) -> *mut GstElement
Returns a mutable raw pointer to the internal GstElement
fn set<T>(&self, name: &str, value: T) where Self: Sized
impl Transfer for AppSink
[src]
unsafe fn transfer(self) -> *mut GstElement
Consumes the current object and transfers ownership of the raw pointer Used to transfer ownership to ffi functions, should be used when an ffi function expects full transfer of an object to avoid the original object to be unreferenced in the process Read more
