pawelsky Added information about the media player in v1.04.0200+ firmwares

 ====== Playing custom videos with sound on DJI Goggles ====== ====== Playing custom videos with sound on DJI Goggles ======
  
-Unfortunately the DJI Goggles do not provide a media player facility - which is too bad since they'd be a very good viewing device. You can insert an SD card but not make much use of it besides storing screenshots and downloading videos from a Mavic wirelessly (and very slowly) for later playback. It has been found that you can place custom videos at the same place and with the same naming convention as those downloaded files and they will play, but without sound (since DJI aircraft videos do not have a sound track DJI probably haven't bothered with sound at all).+===== Firmwares v01.04.0200 and higher ===== 
 +Firmware v01.04.0200 for DJI Goggles adds a media player which can be used to play user provided media files. Videos are read from the microSD card (which gives a pretty much unlimited storage), are played with sound and it is possible to skip forward/back with swipe gestures.  
 + 
 +There are still some errors, quirks and crashes when using the media player (especially with high FPS videos) but hopefully these will be polished in future firmware versions. 
 + 
 +==== Video format ==== 
 +A video file with audio, MP4 container, h.264 codec, 1920x1080 pixels and several sizes below were tested. 30FPS works fine, 60FPS plays but is not as smooth as one would expect, anything above that is usually jumpy or does not play well. 
 + 
 +==== Storing the media on the Goggles ==== 
 +The video files shall be placed in the ///USER_MEDIA// directory. Once loaded the thumbnails will be created automatically and stored in ///DJI_ALBUM/video_thumbnail// directory. There is no need to reboot the goggles to add new video files - it is enough to remove the card, upload new files, put it back in and reopen the media player. Files can be accessed via the //Local Storage// tab of the //Playback// menu

 The goggles however come with 4 preloaded demo videos that play with sound, so we're going to exploit that feature and inject our own "demo videos" in the same location and format.   The goggles however come with 4 preloaded demo videos that play with sound, so we're going to exploit that feature and inject our own "demo videos" in the same location and format.
