Buffer requirements parameter. This is mainly used to increase the requirements of a component.

Fields

hdr: MMAL_PARAMETER_HEADER_T

buffer_num_min: u32

< Minimum number of buffers the port requires

buffer_size_min: u32

< Minimum size of buffers the port requires

buffer_alignment_min: u32

< Minimum alignment requirement for the buffers. A value of zero means no special alignment requirements.

buffer_num_recommended: u32

< Number of buffers the port recommends for optimal performance. A value of zero means no special recommendation.

buffer_size_recommended: u32

< Size of buffers the port recommends for optimal performance. A value of zero means no special recommendation.
