Upipe ubuf manager for sound formats with umem storage

This macro is declared in upipe/ubuf_sound_mem.h source file, line 31.

This function is declared in upipe/ubuf_sound_mem.h source file, line 67.

This function adds a new plane to a ubuf manager for sound formats using umem. It may only be called on initializing the manager, before any ubuf is allocated.

Parameters list:

• mgr: pointer to a ubuf_mgr structure
• channel: channel type (see channel reference)

The return value is an error code

This function is declared in upipe/ubuf_sound_mem.h source file, line 57.

This function allocates a new instance of the ubuf manager for sound formats using umem.

Parameters list:

• ubuf_pool_depth: maximum number of ubuf structures in the pool
• shared_pool_depth: maximum number of shared structures in the pool
• umem_mgr: memory allocator to use for buffers
• sample_size: number of octets in a sample for a plane
• align: alignment in octets

The return value is pointer to manager, or NULL in case of error
