Oculus Go: What to do when there is no sound in a movie or when the left and right are swapped...

The following video conversion tips work everywhere, not just in virtual reality.

For the sake of completeness, I must add that Oculus Go are affordable virtual reality goggles with interesting software that makes them very easy to use, but sometimes things may go wrong. For example, you might want to watch a movie and there is no sound, or the left and right sides are swapped, so the 3D effect does not work. What to do with this?

Perhaps you know that we are developing adventure games for PC, Android and iOS, and maybe you even know the most famous free one, Alice and the Reformatory for Witches has already almost 1.5 million of downloads. But in addition to developing games, we sometimes play with other things, like virtual reality. And now we play with Oculus Go, which are goggles for virtual reality available for $ 200.

With the Oculus Go you can of course play 3D games, view 3D images of different places of the world, watch 3D and panoramatic videos (as well as 3D panoramic videos, of course) and do a lot of other things. Among other things, you can also watch 3D movies that you download to Oculus Go or which are stored on your network drive.

When there is no sound in Oculus Go

From time to time, however, the sound of a 3D movie or a panorama film may not work. Why? Of course, because of a bad codec. Oculus Go, for example, does not work with the DTS sound. So, the sound has to be recoded easily and quickly. How to do it?

We recommend that you download the ffmpeg software. What then? Let's make it simple. So: When you right-click on a file in Windows, the Send To item appears in the menu. You can easily get to this directory by typing this to the Windows Explorer address bar: shell:sendto. And press Enter. Create a convert_sound.bat file at this location and type this inside:

if not exist "Good" mkdir "Good"

C:\xxx\ffmpeg.exe -i %1 -c:v copy -c:s copy -c:a ac3 "Oculus\%~nx1"

Instead of C:\xxx\ you must of course use the path to where you uploaded ffmpeg.exe. And then you just need to  press the right mouse button on the file where you need to convert the sound and choose Send - convert_sound. The Good folder will be created for the file and the file will be converted. The video should convert in a few minutes.

Swap the left and right images in the video

If you have a movie where the left and right images are swapped (for a video where they are next to each other), just follow the same steps as in the previous case - but in the file swap_LR.bat - type:

if not exist "Good" mkdir "Good"

C:\xxx\ffmpeg.exe -i %1 -vf stereo3d=sbs2r:sbs2l "Oculus\%~nx1"

And the next steps are the same as in the previous case.

And when you get bored, try out some of our games for Android, iOS, Windows. For virtual reality they are not available yet, but maybe once... :)
