[−][src]Trait gstreamer_editing_services::prelude::BufferPoolExt
Required methods
fn get_options(&self) -> Vec<GString>
Get a None
terminated array of string with supported bufferpool options for
self
. An option would typically be enabled with
BufferPool::config_add_option
.
Returns
a None
terminated array
of strings.
fn has_option(&self, option: &str) -> bool
Check if the bufferpool supports option
.
option
an option
Returns
true
if the buffer pool contains option
.
fn is_active(&self) -> bool
Check if self
is active. A pool can be activated with the
BufferPoolExt::set_active
call.
Returns
true
when the pool is active.
fn set_active(&self, active: bool) -> Result<(), BoolError>
Control the active state of self
. When the pool is inactive, new calls to
BufferPool::acquire_buffer
will return with FlowReturn::Flushing
.
Activating the bufferpool will preallocate all resources in the pool based on the configuration of the pool.
Deactivating will free the resources again when there are no outstanding buffers. When there are outstanding buffers, they will be freed as soon as they are all returned to the pool.
active
the new active state
Returns
false
when the pool was not configured or when preallocation of the
buffers failed.
fn set_flushing(&self, flushing: bool)
Enable or disable the flushing state of a self
without freeing or
allocating buffers.
flushing
whether to start or stop flushing
