Detailed Description

Defines a struct containing callback functions for a video frame plane memory wrapper struct.


const uint8_t ( get_plane) (void *user_data, enum otc_video_frame_plane plane)

Called when a video frame plane is requested. It is mandatory to implement this callback function.

Parameters : | | | | --- | --- | | user_data | A pointer to the user data bound to this struct. | | plane | Given plane. |

Returns : Pointer to video frame plane.


int(* get_plane_stride) (void *user_data, enum otc_video_frame_plane plane)

Called when a video frame plane stride is requested.

Parameters : | | | | --- | --- | | user_data | A pointer to the user data bound to this struct. | | plane | Given plane. |

Returns : Video frame plane stride.


void(* release) (void *user_data)

Called when you can release the video frame data from memory. It is not mandatory to implement this callback function.

Parameters : | | | | --- | --- | | user_data | A pointer to the user data bound to this struct. |


void* reserved

A void pointer to a memory area holding reserved resources used for the internal implementation.


void* user_data

A pointer to any useful user data related to this struct.
