Public Attributes

size_t	num_buffers_allocate_on_connect Defines the number of buffers to auto-allocate when the stream is set up.
size_t	num_buffers_allocation_threshold Defines the minimum number of required free buffers.
size_t	num_buffers_free_threshold Defines the maximum number of free buffers.
size_t	num_buffers_max Defines the maximum total number of buffers this sink will allocate.

Specifies a custom allocation strategy.

size_t num_buffers_allocation_threshold

Defines the minimum number of required free buffers.

If the number of free buffers falls below this, new buffers are allocated.

size_t num_buffers_free_threshold

Defines the maximum number of free buffers.

If the number of free buffers grows above this, buffers are freed.

If set to 0, buffers are not freed automatically.

Note: If num_buffers_free_threshold is not 0, it must be larger than num_buffers_allocation_threshold + 2.

size_t num_buffers_max

Defines the maximum total number of buffers this sink will allocate.

This includes both free buffers managed by the sink and filled buffers owned by the program.

If set to 0, there is no limit to the total number of buffers.
