3 Professional Methods to Solve "DJI 4K Don't Play on VLC"

DJI drones has claimed a market share of half or more rescently. Some models of drones such as DJI Phantom 4 Pro, DJI Inspire, can shoots DCI 4K (4096 X 2160) video and UHD 4K (3480 X 2160) video compressed with MPEG-4 AVC/H.264 codec in MOV wrapper, however finding a proper media player to play is a head-scratching task and turn into an agony when you lack a super computer. Here you will find the way to solve this problem, read on.

When we search on Google, we found that "DJI 4K vdieo don't play on VLC" would be a common problem. Even quite powerful i7 SSD PC don't play DJI Inspire / Phantom 4K 100Mbps bitrate video properly. A practicable way is to slow speed to 0.67, Media Player Classic (k-lite codecs) runs and play those 4k footage smoothly. However, for VLC fans, they give up this way.


Why VLC Can't Play DJI 4K Footage?

3 Method to Play DJI 4K Footage on VLC Smoothly

Method 1: Update VLC to 2.2.6 version

Method 2: Enable Hardware Acceleration in VLC to Play DJI 4K Video

Method 3: Downscale DJI 4K Video to 1080p for VLC Smooth Playback


Why VLC Can't Play DJI 4K Footage?

In fact, the 4K video playback including DJI 4K recordings with VLC has strict requirements on the computer's processor and graphics chip. Sometimes, even if your computer meets the requirements, you may find that DJI 4K video plays back choppy. This is due to the immense processing power required to play 4K. You can try the below 3 methods to handle the problems.

3 Method to Play DJI 4K Footage on VLC Smoothly

Method 1: Update VLC to 2.2.6 Version

With preparation for Ultra-HD video and a special care to support more formats, 2.2 is a major upgrade for VLC. Download it here and re-open your DJI Phantom 4 4K videos in VLC Player for 4K video playback.

Note: Although version 2.2.6 of VLC offers 4K playback support, it still does not support 4K video from DJI Phantom 4 playback perfectly: there is stutters, not showing audio, etc issues.

Method 2: Enable Hardware Acceleration in VLC to Play DJI 4K Video

If you ungrade VLC verison but still fail to play DJI 4k on VLC, you can try the second method. You can fix this issue by enabling the GPU accelerated decoding feature in VLC, this feature in theory uses the processing power of the graphic card to lighten the load on the processor of the system.

However, according to VLC's GPU decoding page, this feature is only available for H.264 streams. In addition, as the data is decoded in the GPU at the decoding stage and then transferred back to the player so that the other stages, filtering and streaming for instance, can be processed, this process can under under circumstances be slower than without GPU acceleration enabled. What's more, the VLC GPU decoding is only available for select operating systems. While Windows Vista and newer versions of the Microsoft operating system are supported, Windows XP is not at this point in time. The majority of graphic cards should support hardware acceleration just fine. Make sure you have installed the latest drivers though.

How to enable hardware acceleration in VLC?

Open VLC Media Player and click on Tools > Preferences or press Ctrl-P to open the settings window of the program. If you are using the simple settings interface, click on Input & Codecs on the left sidebar and check the Use GPU accelerated decoding box there.

VLC Enable GPU Acceleration

If you are using the "all" interface select Input/Codecs > Video Codecs > FFmpeg > Hardware decoding instead to enable acceleration this way.

Click on the save button afterwards and restart the media player to work with the new setting. Try playing several video files to see if hardware acceleration makes a difference in terms of playback. If it does, keep the setting enabled. If it does not, just go back to the settings to uncheck the option again.

Method 3: Downscale DJI 4K Video to 1080p for VLC Smooth Playback

It will be GPU consuming and very jerky if you play DJI 4k footage on VLC media player, and if you don't possess a powerful computer, that will be worse. So how about compressing your DJI 4k to 1080p that will be compatible with most devices, like smartphone, tablets, labtops, or game console. By the way, this way has lower requirements on the computer's processor and graphics chip than 4K video.
