This function allows injecting a video frame into the platform and letting the CameraProcessor handle the video frame.
- Parameters
-
| frame | a video frame to be pushed into the internal queue. |
- Returns
- 0 on success, otherwise returns EINVAL on error occurs.
- Note
- This function is only used in our test suite to facilitate our automation tests and it is subject to change at any time.

) |
| |
|
inlinevirtual |
Read next available video frame.
Anbox will call read_frame() to query the plugin for the next available video frame which is then forwarded to the Android container. If no video frame is available and timeout is set to -1, the function must block until the next video frame is available.
- Parameters
-
| frame | Pointer to the available video frame to be sent to the anbox container. |
| timeout | maximum number of milliseconds to wait for the next available frame. The following possible values for timeout must be handled:
| timeout | Behavior |
| 0 | Non-blocking mode; return -EIO immediately if no video frame to process. |
| < 0 | Block indefinitely until a video frame is available. |
| > 0 | Wait up to a maximum of timeout milliseconds for a video frame. |
