Oculus Go - Browser - Go VR - VIDEO WONT WORK - DeoVR Player

Hi all, i have problem with playing video with VR mode on Oculus Go.

I implemented DeoVR player to page successfully, on mobile devices and destkops are ok.

But when i wear goggles video play only on "normal mode", when i clicked to Go VR, now im see only looping 1sec from video.

I encoding original video 6000x3000 to these sizes with ffmpeg ->

ffmpeg -i ./video-full.mp4 -y -acodec copy -vcodec libx264 -filter:v scale"=w=trunc(oha/2)2:h=2400" -f mp4 -crf 20 -movflags +faststart -preset slow -tune film -x264-params mvrange=511 -pix_fmt yuv420p -colorspace bt709 -color_trc bt709 -color_primaries bt709 -color_range tv -maxrate 50M -bufsize 100M ./video-180-2400.mp4 -filter:v scale"=w=trunc(oha/2)2:h=1440" ./video-180-1440.mp4 -filter:v scale"=w=trunc(oha/2)2:h=720" ./video-180-720.mp4

Any ideas to resolve this issue? Thank you.

Hi, did you ever manage to resolve this? I am having the exact same problem on my website and I can't get any help anywhere that I've tried so far.

Hello,

yes it's okay now. I came across a preset for ffmpeg.

ffmpeg -i ./video-full.mp4 -y -acodec copy -vcodec libx264 -filter: v scale "= w = trunc (oh a / 2) 2: h = 2400" -f mp4 -crf 20 -movflags + faststart -preset slow -tune film -x264-params mvrange = 511 -pix_fmt yuv420p -colorspace bt709 -color_trc bt709 -color_primaries bt709 -color_range tv -maxrate 50M -bufsize 100M ./video-180-2400.mp4 -filter: v scale "= w = trunc (oh a / 2) 2: h = 1440" ./video-180-1440.mp4 -filter: v scale "= w = trunc (oh a / 2) 2: h = 720 "./video-180-720.mp4

But some videos have problem on mobile - 180-720 its a laggy...

Thank you for the reply - I'm glad you get it sorted out.

Excuse my ignorance but where does the encoding take place? I'm shooting on a Vuze XR in 180, I then render the footage in Vuze studio and edit on Premier Pro. The finished 6K 30fps version plays fine on my Go when I load it directly to the headset but I encounter the problem that you describe after I upload and transcode to my website (I can't get my website to function well in DeoVr but that's a whole other issue - I'd just like to see the VR vids play in a web browser in 3D properly).

Thanks,
Mike.
