How to play 180° 3D video

Hi, i'm dicovering my Gear Vr, and i'd like to know how to play a 180° 3D video?
For 360° it's ok, with TB or LR if in 3D.

But for 180°... (i have tried with 3D file, but maybe the same problem without 3D, but i don't think so, because the screen should be cut)
If the video is Top-Bottom, no problem, but if it's Left Right, it automatically zoom.

I use Oculus 360 Video, because in france, we don't have Milk VR.
But tonight i will try ton install it with Hola.

So if you could help me, it would be awesome.
Thanks.

I had the same problem - I could only playback 3dv (vertically stacked) 3D videos.

I managed to convert SBS videos using ffmpeg (and I posted how I did this, see http://video.stackexchange.com/questions/17131/convert-horizontal-side-by-side-to-vertically-stacked...)
I also had to add a textfile named video_3dv.txt containing


{
"format": "3DTB"
}


But I still have a problem: the resulting video is being played in 360 degree mode but the video only contains 180 degree data.
Is there a way to add meta data for the oculus video player to play it in 180 degree mode?
I already tried naming it video_180x180_3dv.mp4 but this has no effect.

If you're using MilkVR you should be able to view 180 videos using 180x180 in the name.
Add 3dv or 3dh for stereo. Oculus 360 video app will not play 180 videos correctly as far as I know.

For those of you who don't want to or are not able to install MilkVR - I found a way to convert Oculus Rift style left-right aligned 3D videos into the bottom-top-aligned 3dv format the Gear VR supports.

Basically you crop and stack the left and right picture of your video and apply some padding to get the right format and add the <video file name>.txt with meta information.

Because the ffmpeg call is quite complicated I wrote a script which does everything:

https://github.com/frans-fuerst/magic/raw/master/LR2TB.py

You need a recent version of ffmpeg (https://ffmpeg.org/download.html)

Call the script like this:


LR2BT.py Video.mp4


If you have downloaded a copy of ffmpeg call it like this to point to the right executable:

LR2BT.py --ffmpeg=path/to/ffmpeg Video.mp4


The result will be two files: Video_3dv.mp4 and Video_3dv.txt.

Should work with Windows, too. You need Python (2/3) and ffmpeg (see link) - haven't tried.

First You have to make directory movies/3D movies then paste your 3D movies here.
Each 3D movies unto add "same name.txt" file witch contain that text :

{



"format": "3DTB"



}

You can watch your 3D movies in Cinema mode on the Moon :)!!!

"_TB" for top/bottom



"_BT" for bottom/top



"_LR" for left/right



"_RL" for right/left

GearVR video Quick Guide:
Make some new folders in your video folder. 360Videos and 180Videos. Put your video in it's respective folder. (360 degree videos in the 360Videos folder and 180 degree videos in the 180Videos folder)
If the video is 3D simply add to the end of the filename either "_TB" if its top and bottom format or "_LR" if its left and right format. (Ex. "Filename_TB.mp4" or "Filename_LR.mp4")

If you can find it,. I highly recommend VAR's VR Player Pro   https://play.google.com/store/apps/details?id=com.VaRs.VRPlayerPRO ; It gives you all sorts of options for playing different video formats.  Including 180 Degree side-by-side.  It even lets you play standard videos as if they were 3D.  Aaand they give you the option of setting wether you want to watch videos statically (fixed eye position) or floating (head tracking on the video) for all video formats.  So far, its pretty stable.  It IS adware, but you really only see the ads when backing out of videos play mode.  As long as you watch videos through, no ads, and as long as you next or backward to a video no ads..

In MIlk VR you can watch them by adding

"180x180_3dv" for Top bottom stereoscopic 3D 180° and "180x180_3dh" for Left right stereoscopic 3D 180° to the file name.



And dont use Hola as it apparently can not be trusted.

 Is there a metadata tag that can be used instead of needing to concatenate filenames with this tag information?
