Convert MKV for playback on Gear VR with 3D effect

Samsung Gear VR is a mobile virtual reality device, which acts as the headset's display and processor. One advantage of Samsung Gear VR is that Samsung and Oculus has made it easy to import and watch your own local movies in virtual cinema mode. Though Gear VR claims to support MKV formats, somtimes we still encounter Gear VR MKV playback problems. Some VR movies in MKV play nicely while others won't play on your Gear VR or playback with no sound. So what's the matter? Check out the reason and solution for "No sound in Gear VR" here.



Why Some MKV Won't Work with Gear VR on Galaxy S7/S7 Edge/S6/Note7/5/4

Samsung Gear VR by default supports most common file formats including MKV, MP4, AVI, and FLV. When it comes to playing 3D videos, Gear VR requires either side-by-side or top-bottom (top down). However, a MKV is just a container format, holding video, audio, image or subtitle files in it. The video and audio files in different MKV files can be encoded with different codecs. For example, an MKV file with DTS audio can't be rendered on Gear VR. Fast research in the Internet has shown, that the problem was in audio codecs and the list of supported by Oculus audio formats. As it turned out AC3 and DTS audio are not supported by Oculus Video Players yet. If your MKV media contains AC3 or DTS audio, it will not work on Oculus player in Oculus Cinema. 

Three solutions to get MKV to play on Gear VR with proper audio

Soluton 1:  Encode MKV to Gear VR with VidCoder (Free but a little complex)

Basically you won't be able to play MKV file on Gear VR as it is, you will need to encode it to the supported format. Here comes a free solution that I chose for myself after browsing dozens of articles and forums.  

1. You will need to download and install on your computer VidCoder   – free but simple to use and very functional software.

2. Run the app and choose the file you want to encode.



3. Than choose the folder you want the encoded file to be saved and hit Settings button, we will create a preset so next time when you need to encode the movies the further steps would be unneeded.



Pay attention, that in case your movie has several languages, you need to choose and audio track you want to use. Settings screen has 4 tabs, but we will need just 2 of them.



In Picture tab, select Container MP4 and make sure no cropping would be done to the output file. That means that the picture will not be resized and there will no quality loss for the picture.

4. Now move to the Audio Tab

Choose AAC or MP3 as the codec and set Stereo as Mixdown (of course if you have fancy 5.1 earphones you can leave at as default).



5. Now hit Save button and enter the name of the template, so the next time you won't need to enter the settings again.

6. Now go back to the VidCoder home screen and press Encode button.



Now wait till the process is completed and copy the file from your computer to the phone.

That's it! By the way, this program works perfectly fine with 3D movies as well, and won't need to change the Settings to encode your 3D video, and then refer to the steps to play 3D on Gear VR

According to Oculus Support Center, we recommend using 1280x720 HD resolution to encode your videos.

We also recommend using a higher bit rate than a typical web stream at that resolution, as the pixels in your video will be magnified on the phone's screen.

    The optimal bit rate is content dependent, and many videos can get by with less, but 5 Mb/s should give good quality. (Note: While H.264 is the recommended video coding, H.265 videos can also be played, Dimo Video Converter Ultimate can also encode any video to H.265 videos for watching)
