* pool to the OMX port or provide the OMX buffers directly to other
|
|
|
|
* elements.
|
|
|
|
*
|
|
|
|
*
|
|
|
|
* A buffer is in the pool if it is currently owned by the port,
|
|
|
|
* i.e. after OMX_{Fill,Empty}ThisBuffer(). A buffer is outside
|
|
|
|
* the pool after it was taken from the port after it was handled
|
|
|
|
* by the port, i.e. {Empty,Fill}BufferDone.
|
|
|
|
*
|
|
|
|
* Buffers can be allocated by us (OMX_AllocateBuffer()) or allocated
|
|
|
|
* by someone else and (temporarily) passed to this pool
|
|
|
|
* (OMX_UseBuffer(), OMX_UseEGLImage()). In the latter case the pool of
|
|
|
|
* the buffer will be overriden, and restored in free_buffer(). Other
|
|
|
|
* buffers are just freed there.
|
|
|
|
*
|
|
|
|
* The pool always has a fixed number of minimum and maximum buffers
|
|
|
|
* and these are allocated while starting the pool and released afterwards.
|
|
|
|
* They correspond 1:1 to the OMX buffers of the port, which are allocated
|
|
|
|
* before the pool is started.
|
|
|
|
*
|
|
|
|
* Acquiring a buffer from this pool happens after the OMX buffer has
|
|
|
|
* been acquired from the port. gst_buffer_pool_acquire_buffer() is
|
|
|
|
* supposed to return the buffer that corresponds to the OMX buffer.
|
|
|
|
*
|
|
|
|
* For buffers provided to upstream, the buffer will be passed to
|
|
|
|
* the component manually when it arrives and then unreffed. If the
|
|
|
|
* buffer is released before reaching the component it will be just put
|
|
|
|
* back into the pool as if EmptyBufferDone has happened. If it was
|
|
|
|
* passed to the component, it will be back into the pool when it was
|
|
|
|
* released and EmptyBufferDone has happened.
|
|
|
|
*
|
|
|
|
* For buffers provided to downstream, the buffer will be returned
|
|
|
|
* back to the component (OMX_FillThisBuffer()) when it is released.
