Trait gstreamer_base::subclass::prelude::PushSrcImpl

pub trait PushSrcImpl: PushSrcImplExt + BaseSrcImpl {
    // Provided methods
    fn fill(&self, buffer: &mut BufferRef) -> Result<FlowSuccess, FlowError> { ... }
    fn alloc(&self) -> Result<Buffer, FlowError> { ... }
    fn create(
        &self,
        buffer: Option<&mut BufferRef>,
    ) -> Result<CreateSuccess, FlowError> { ... }
}

Provided Methods

fn fill(&self, buffer: &mut BufferRef) -> Result<FlowSuccess, FlowError>

Ask the subclass to fill the buffer with data.

fn alloc(&self) -> Result<Buffer, FlowError>

Allocate memory for a buffer.

Returns

fn create( &self, buffer: Option<&mut BufferRef>, ) -> Result<CreateSuccess, FlowError>

Ask the subclass to create a buffer, the default implementation will call alloc if no allocated buf is provided and then call fill.
