TVideoFrameBuffer represents a buffer for a single decoded video picture. The
|
|
sl@0
|
25 |
buffer must be contained within a chunk that can be shared across processes.
|
|
sl@0
|
26 |
|
|
sl@0
|
27 |
The frame buffer class is used both for video renderer data flow and with the
|
|
sl@0
|
28 |
MMMFVideoClientBufferSupport extension.
