* The main structure for buffer management.

|
|
* pBufHdr - An array of pointers to buffer headers.
|
|
* The size of the array is set dynamically using the nBufferCountActual value
|
|
* send by the client.
|
|
* nListEnd - Marker to the boundary of the array. This points to the last index of the
|
|
* pBufHdr array.
|
|
* nSizeOfList - Count of valid data in the list.
|
|
* nAllocSize - Size of the allocated list. This is equal to (nListEnd + 1) in most of
|
|
* the times. When the list is freed this is decremented and at that
|
|
* time the value is not equal to (nListEnd + 1). This is because
|
|
* the list is not freed from the end and hence we cannot decrement
|
|
* nListEnd each time we free an element in the list. When nAllocSize is zero,
|
|
* the list is completely freed and the other paramaters of the list are
|
|
* initialized.
|
|
* If the client crashes before freeing up the buffers, this parameter is
|
|
* checked (for nonzero value) to see if there are still elements on the list.
|
|
* If yes, then the remaining elements are freed.
|
|
* nWritePos - The position where the next buffer would be written. The value is incremented
|
|
* after the write. It is wrapped around when it is greater than nListEnd.
|
|
* nReadPos - The position from where the next buffer would be read. The value is incremented
|
|
* after the read. It is wrapped around when it is greater than nListEnd.
|
|
* eDir - Type of BufferList.
|
|
* OMX_DirInput = Input Buffer List
|
|
* OMX_DirOutput = Output Buffer List
