[Q] Cmoar Cinema VR?

Hi Guys.
It seems that focusing and stuttering is the big issue for me..its too big on the eyes and stutters during playback including local files.
Dose anyone had luck with this app? am i missing a setting somewhere?
Thanx for your time.
hi,
Im experiencing the same, big stuttering on movement and playback. (Archos VR glasses w/ note 3)The demo works fine, but the paid app doesn't. Big dissapointment. I thought maybe a rom issue (5.1.1), but then the demo version would not work either, i guess.
I'm using fibrum VR cinema for alternative, works like a charm.
It's because of the sensors, only the apps from the oculus store use the sensors in the HMD, the rest is for cardboard and uses the phones sensors so not that accurate as the oculus ones.

Looking for some app for Android. Doesn't exists?

Hi all,
I'm a motorbike rider and I usually go on the weekends to do routes with my motorbike. Some weeks ago I installed a stand for the smartphone that allows me to record the routes.
What I want, and is weird that it not exists, is some kind of camera app that record with extra info in the video like speed or inclination.
I saw some dash cams apps for cars, but it has this info like the speed in the screen during the record but when I try to see the recorded video it not appears.
Thanks in advance!

Question Video is Rendering Over Sharped in Streaming apps like YouTube, Prime Video and Local player's also like MX player etc.

Hello Everyone,
A few days ago, I purchased the Redmi Note10s, which worked very fine in every aspect of the smartphone, but I've found issues of video rendering in apps like YouTube and others even in 1080P.
But The Strange thing is that while playing the same video on the youtube website using Firefox browser it renders perfectly and Amazing.
Below I've attached the screenshot of the same video playing in those two different apps.
YOUTUBE:
As You'll see below the SS of the YouTube Sample is Over sharped and isn't pleasing to the eyes
FIREFOX:
In the samples of Firefox, it renders the way we want with perfect colours and sharpening.
Is this problem with Software or GPU rendering, I don't know. If anyone having this phone please share your opinions or thoughts on this, and also let me know if anyone facing the same issue.
P.S: this is my first post on XDA community, hoping XDA community will help with this problem.
i have the same issue ... i sent it to mi store to check it up for a few days and they said it was alright ...
i also checked another note 10 s device in the store .. it has the same issue
the issue exist in youtube and google chrome ....
not sure if its a software issue that will be fixed or bad qc
since u posted 20 days ago .. did u do anything about this issue ?
I have come across the thing called video decoding, which is done mainly by GPU or processor. In our phone, a MediaTek processor is used which is using a technology called MiraVision to render the HDR video which causing the issue while playing video in lower quality like 480P. Some solutions I found on Reddit is saying to disable the hardware overlays to solve the issue, as this problem already faced by redmi note 8 users. But didn't solve our issue.
But idk why I'm used to this as video of 720P is much sharper and feels good now
i kinda like it although it might have to do something with miravision
best is to ask people using realme 7 and redmi note 8

Try to instal Activity Launcher then search "AI HDR Enhancement" under "Settings" then turn it off
Try youtube vanced. No such issue with it.

It maybe an issue with MiUI's VP9 renderer (VP9 is a new codec developed by Google as a free alternative to HEVC ,or H265).
The codec is used by default by YouTube since it offers higher compression compared to previously used H264 codec (AVC).
The codec is all fine, and it is absolutely recommended to use it since it offers better clarity and saves data at the same time.
The problem is with MiUI's VP9 rendering algorithm which is over-sharpening the video. I suggest you to contact Xiaomi to fix the issue, and disable VP9 in YouTube Vanced for time being.
If the above solution didn't work, you may try changing the decoder in MX Player [Try all 3 decoders - HW, HW+, and SW.]
If you don't observe any changes, use the mx_aio custom codec.

Pls reply if this worked or not, so that others would benefit.
Has this been fixed? is it even fixable via firmware updates?
As far as i know the Redmi Note 8 Pro has the same problem and still has it to this day
I was going to pick this phone up for my mother by this is definitely a turn off

try chaging the codec override in vanced setting , also to enable extra options in the override menu tap many times on about to unlock hidden setting
Begonia user here. .as for most possible fix
change "ro.vendor.mtk_pq_support" from 2 to 0 (in Vendor/Build.prop)
*well, it need root access to do that.
I also have the same problem on JMGO O1 projector. Every time I play another video I have to go into settings and adjust the sharpness, from 0 to 1 then back to 0.

How To Guide Capturing CinamaDNG on the ZTE Axon 30 Ultra

The still under heavy development MotionCam enables the ZTE Axon 30 Ultra to capture RAW video in form of CinemaDNG.
This is virtually a sequence of DNG frames with a seperate audio track generated by the app.
The app allows cropping from the full resolution of the sensor (but no scaling) so that you can create content that the free version of DaVinci Resolve is able to process.
The app detects all of the camera modules on the back.
During capture tha app stores the data in a container. From within the app the DNG sequence can be exported from each container.
In DaVinci Resolve you can simply add the complete folder to the timline and apply any grading there like on any other video clip except there is so much more range for processing without the result falling apart.
Besides the ablity to capture RAW video there ist also the opportunity to create naturally looking JPEG images on each of the modules on the ZTE Axon 30 Ultra. An option to store DNGs is there as well. Also an interesting burst mode that captures a rapid sequence of images that can than be used in the app to create a single output image where you can control the settings in a wide variety of parameters. The app provides a night mode on all the camera modules as well. Maybe not as perfect as on the GCam but good enough.

Accessing a USB Camera on a Galaxy Note20

Hopefully there's a simple answer to this, and hopefully this is a place to find it!
I'd like to be able to switch between the front, back, and a USB-C connected camera for input to streaming apps (notably Facebook Live, and Zoom conferencing, but would like a more general solution). Ideally, video mixing (e.g., picture-in-picture), would be nice.. The primary application is to stream live interviews, site walkarounds, etc., from a gopro or the camera in a pair of AR goggles. E.g., live stream the view from the head-mounted camera, with an inset view of me, from the phone's front camera.
Right now:
- I can almost do it all from a Microsoft Surface - the basic camera app allows selection from front, back, external USB camera. Control of camera selection is through the system settings dialog.
- On a Samsung Galaxy Note 20, I can't seem to find the equivalent of a system-level setting. The basic camera app allows for picture-in-picture still & video from the front/back cameras - but doesn't seem to have a way to select an external camera. Facebook live allows switching front/back, doesn't seem to do picture-in-picture.
Documentation for all this stuff seems hard to find. I've been pouring through the various android developer sites, and device related sites - lots of stuff on low level code interfaces, nothing on what's actually coming across the cables, and mostly out-of-date youtube videos on how to do very specific things with very specific external video switches, and various downloadable apps that don't seem to work very well.
Which leads to the following questions:
- Are there any deeply buried settings - in Android, Samsung Developer Tools, or Facebook, Zoom, Teams - that let one select a usb camera? (Bonus for allowing picture-in-picture.)
- Any recommendations for an Android video switch/mix application that inserts itself between the system video interface, and standard apps?
Hopefully, amongst all the noise, there's a simple solution.
Thanks very much for any assistance anybody can offer.
