Try with VLC 3.0.0 nightly build, a recent one.

Set it to use DXVA3 aka D3D11:
Tools -> Preferences -> Video
Output = D3D11

Tools -> Preferences -> Input/Codecs
Hardware accelerated decoding = D3D11 Video Acceleration

Then save, exit and restart VLC.

Hi Lotesdelere,

I wanted to thank you for this post. This also applies if you have 4k 60FPS from a GoPro. The latest stable VLC will not play it, but version 3+ nightly with the D3D11 settings played perfectly.

kenshin159, can you give me some details on how you are streaming from the GoPro? I have had issues with this for a long time now, and can never get a useful stream from Hero4,5,6 Cameras. Picture is garbled and useless.
The URL I typically use is udp/h264://@:8554. With the v2.2.8 and older builds, I can at least get a garbled video, but in the v3.0.0 or v4.0.0 nightlies, I don't get anything at all. I can use FFPLAY to play the GoPro stream directly, with no problem, or I can use FFMPEG to re-encode the GoPro video, and then VLC can pickup the re-encoded stream just fine. The FFMPEG command I use basically copies codecs but removes the Data Stream (metadata that GoPro inserts):

Example:
ffmpeg -f:v mpegts -probesize 8192 -i udp://10.5.5.9:8554 -sn -c:av copy -f mpegts udp://127.0.0.1:8555

I can then connect VLC to udp://@:8555 without having to specify the /h264 in the URL. Works great! The -SN in the ffmpeg command removes the data stream, which could possibly be what is messing up my VLC player's ability to decode the video?

Thanks!

Sorry to hijack this thread. I'm realizing now that you all are probably referring to playing back files rather than watching the live stream from the GoPro. Disregard!

Hi I literally just signed up to this forum to post my thanks. It was driving me crazy that I couldn't play my iPhone X vidoes with VLC anymore, but somehow windows media player would play them. I found this thread and it fixed my issue too. I downloaded 3 rc6 and the video plays now (after changing to D3D11 video acceleration) as mentioned above.
