Installing this mod will give you the ability to record 4K UHD/DCI videos on your OnePlus X, as well as record videos at a consistent 30 frames per second in all lighting conditions (no more frame drops/stuttering when recording videos at night). This mod is compatible with most ROMs.

This is a custom camera HAL I created using CAF's vanilla camera HAL sources. As a lot of reverse engineering was involved in this, there are some caveats (see below).

Do NOT install this on my CM13 ROM!

Note that some ROMs using older proprietary camera libraries (such as the newest version of H2OS) will not benefit from 30 FPS video or my anti-shake algorithm.

If the 4K option does not appear in the camera app you're using, or your camera stops working, then clear data for the camera app that you're using.

Notable features:

• 4K UHD and DCI video recording
• Consistent 30 FPS video recording in all lighting conditions
• Intelligent anti-shake algorithm (significantly reduces motion blur when capturing photos)
• Faster autofocus in low lighting conditions
• No stuttering in camera viewfinder
• Improved photo quality
• Photo capture up to 4208x3120 resolution (instead of 4160x3120)

Caveats:

• No ClearImage
• No manual mode only in the OnePlus Camera app (other apps that support manual ISO and manual exposure work fine)

I tested it on CM12.1 and OxygenOS 2.2.0, and it appears to be working. Tested 4k UHD recording in Google Camera and it works.

The 4k video option won't show up in the OxygenOS camera app until you clear data for the app.

Let's see how this goes :silly:

Holy crap the legendary sultan developing for the one x?!?! Any plans for a oneplus x rom as well?

 

[shinodoigt]

Super nice, waiting for Manuel Camera Controls as said in the post but this is already awesome

Because of Enormously crappy camera videos, I was having thoughts of selling this one. Seems like my money is saved. Kudos to you. :highfive:

 

[sathyakaushik4]

If the camera had the capability to record to 4k,why didn't one plus include it in oos?

 

[mieru]

Flashed on temasek v4.0 and had a bootloop after that. Needed to reflash the rom.

They didn't know how to fix it. There's a software bug with 4k on Snapdragon 800/801 chips that causes the 4k video to record at 7 FPS. This is a very difficult bug to fix (took me weeks to originally fix it on my OPO), so it isn't surprising that they decided to move on to other things instead of trying to solve it.

The media_profiles.xml that comes with my package probably has some things in it that your ROM doesn't like. I'll have to test it myself to get a log so I can fix it.

Not enough time/energy/motivation for that right now. Have a camera HAL instead

Don't they scout for talent on these Developer forum's if they have such dumb people sitting and developing ?

I heard a lot about you from my colleagues on OPO( obviously positive things )..... Welcome here :fingers-crossed::good:

they already looked for sultan
but since he hasnt grad yet they didnt hire
edit: well thats what they said on AMA

 

[taaeem]

Morning
Any open-source plans? Or can't you share because of reverse engineering? Will test soon

EDIT: UHD works fine and everything else also good work

 

[Vito-45]

getting back to OxygenOS to try it !!! Super job Sultan

 

[Loureiro]

Nailed it!

@Sultanxda, add to the 1st post that slowmotion mode on OOS camera app won't perform as expected. Didn't tested much, but it seems it is recording at 30fps.

It does not bothers me at all. Being possible to record at night is a big step forward.

 

[alabama20]

Any samples? I'm getting to the point to install a custom recovery. I don't care about HDR or clear Image at all.

 

[MarkoPam]

Just testing it.
I flashed it over OOS 2.2.0 with blu_spark v91.
Gonna upload some samples soon.
