DJI action cameras and drones creating in sd card mp4 video files and simultaneously generated LRF files that mean Low resolution file. This file MPEG-4 format 1280x720 resolution 29fps and about 8000 bitrate, must can play in any devise. 4k Resolution video file can not play any device, like raspberry pi, but LRF file creating for this reason. In sd card file list not showing LRF files, just mp4. Can somebody make this issues.
