函数原型​

function UAV_LiveView_H264Callback​

  • 功能： H.264 码流回调处理函数。
typedef void (*UAVLiveView_H264Callback)(int32_t payload_id, const uint8_t *buf, uint32_t len);

function UAV_LiveView_Init​

  • 功能： 码流模块初始化。
T_UAVReturnCode UAV_LiveView_Init(void);

function UAV_LiveView_Deinit​

  • 功能： 码流模块反初始化。
T_UAVReturnCode UAV_LiveView_Deinit(void);

function UAV_LiveView_StartH264Stream​

  • 功能： 启动获取 H.264 码流。
/**
 * @param position: Camera position for the H264 stream output.
 * @param source: sub-camera source for the H264 stream output.
 * @param callback: Callback function in a callback thread when a new h264 frame is received
 */
T_UAVReturnCode UAV_LiveView_StartH264Stream(int32_t payload_id, E_UAVLiveViewCameraSource source, UAV_LiveView_H264Callback callback);

function UAV_LiveView_StopH264Stream​

  • 功能： 停止获取 H.264 码流。
/**
 * @param position: Camera position for the H264 stream output.
 * @param source: sub-camera source for the H264 stream output.
 */
T_UAVReturnCode UAV_LiveView_StopH264Stream(int32_t payload_id, E_UAVLiveViewCameraSource source);
