HwDevice Tunneling custom interface.
|
|
sl@0
|
31 |
Controllers or other DevVideo clients can use this interface in order to setup
|
|
sl@0
|
32 |
a tunnel from one HwDevice to another. For instance this would allow a video
|
|
sl@0
|
33 |
decoder to be tunneled to a video encoder for transcoding use cases.
|
|
sl@0
|
34 |
|
|
sl@0
|
35 |
Clients must query the HwDevice at both ends of the tunnel for the custom
|
|
sl@0
|
36 |
interface in order to ensure that both devices support tunneled operation.
