generates (Status status)
Pass p fence to the node if it supports fences.Otherwise, wait on p fence before calling OMX_EmptyThisBuffer().The node will take ownership of the fence even if this call fails.
If the port is in metadata mode, the buffer will be updated to point to the new buffer passed in via p omxBuffer before OMX_EmptyThisBuffer() is called.Otherwise, p omxBuffer is not used.
| Details |
| Parameters |
buffer
|
Id of the buffer to fill.
