Remarks¶
This interface specifies the information of the video file to be found (by event). After the call is successful, the NET_SDK_FindNextEvent interface can be called to obtain the file information. The video files found by event are based on the start time and stop time, so only playback by time NET_SDK_PlayBackByTime() is supported.
