Need Dev Assistance to rotate video from camera 90 degrees.

Hey Folks - I could use some help here I am stumped.
I am working on a project to launch one of my model rockets and stream the launch video live via USTREAM (using an LG Revolution modified to be onboard). The issue is USTREAM sets the camera to landscape mode so the phone needs to be held in the landscape position for the video feed to be oriented properly for viewing. The problem is I need the phone to be oriented in the PORTRAIT position due to size limitations of the rocket itself.
USTREAM does not offer the ability to rotate the video stream.... so I was wondering if anyone (dev?) can write a middleware app that will force the camera output to be rotated 90 degrees before the application layer receives the stream? Is that even possible?

FYI: I have tried rotating the camera physically but the connector ribbon is too short and doesn't afford the flexibility for such a move. Creating an "extension" cable is also not in cards since the plugs are nano-sized surface mount.
Thanks in advance...

I have no idea how to do that but please let us know about the launch. Awesome project!

This really does not belong in Development so I have gone ahead and moved it. The project does sounds interesting and I wish you good luck.

Launched the rocket and As-droid-naut this past weekend (minus the LG) - here is the thread I started in the General area if you want to see what I'm up to:

Dashcam
Did you find a solution?
I have tested a lot of dashcam-apps (f.i. 640x480) and the phone in mounted in portrait, the video is only in portrait (480x640). On the pc i have to transform it 90 degrees.

Camera gets its positioning from the accelerometer. Need to somehow fool the camera into thinking it is vertical all the time.

Thanks for the quick response.
That is not the problem. (It is easy, to rotate the video later (and maybe crop) on the pc.
My phone camera has 8 MP CMOS (Landscape 3264x2448 or Portrait 2448x3264)
I need only the upper 720x480 (or better of the 2448x3264) and not 480x720.
The lower part of the video is waste. (only the dashboard, what is not very interesting)
(If I rotate my phone 90°, i see only the dashboard and a little bit of heaven, but no street.)
A higher mounting of the phone holder is not possible.
The best solution is a dashcam-app with a possibility of selecting a video area. Why is it so difficult to program?

vertical display

Is there a way to force the chromecast to display what is on the screen as rotated. I have a tv that is turned vertically and I want my vertical devices display to take up the whole screen.

If you stretched the image everyone would look like aliens...what I'm saying is it would massively distort the image.

Well thats good to know?!? So bavk to the question at hand... can the mirroring be forced to be displayed in a rotated state? Heres an example of my tvs orientation...

No because the TV would have to do the rotating....
No matter how you turn the TV the TV still considers the TOP to be the TOP!
CCast has no ability to change that or re rotate its output on it's own....
The only way I can think of to do what you propose would be the use of an expensive device that can take any input and rotate it before it gets into the TV.
And those would cost in the thousands.

Do you have an example or a link to such a device?

I work in digital signage and we have 1,000s of screens which work like this. And software and hardware which deals with it. Its all commercial grade though, which the Chromecast isn't.
I'm sure technically the CC *could* do it, but I don't think google would spend time enabling it to be honest. So without rewriting a large chunk of the firmware, then no you can't.

You could perhaps code a custom app and CCast Receiver that could allow you to rotate video to the proper orientation.
The Difficulty would be in how you would go about doing that...
Two Methods I can think of are:
1 - rotate the video during transcode before sending it to the receiver app. (key issue will be power of a mobile unit to Transcode the Video)
2 - Create a receiver app that can rotate it's input on the fly. (probably difficult to pull off due to sandbox and memory limitations of the CCast)
The device I linked to above might very well work with a CCast since it has an HDMI input. But you may have to trick the device into multi Monitor upscaling mode to get the right effect.
I don't have any experience with the quicks or cheats on that device so be sure to give it a test run to ensure it meets your needs before you buy!

Poor image quality, CC vs DLNA, why?

Hello Guys, please help me ti establish if this is a fixable issue or this is the standard behaviour of the CC.
I cast a photo to an LG Smart TV, I see a poor quality of the CC against sharing with DLNA smartshare function of the TV.
I tried to take a shot of the issue, do you see the differences?
DLNA:

What do you think? If this is the CC quality I will send it back...
Thank you

The CC images seem to be scaled down, probably to less than 1080p, and the scaled up to fit the screen. But that is, what can happen when using the cloud. The images casted locally look fine with the apps I tried.

The important question here is exactly how are you using Chromecast to send those images?
Screen mirroring happens as device resolution - unless you have a 1080p device, you will not get fully quality.
Apps casting to Chromecast - that depends on the app.
It is also possible your Chromecast is negotiating a lower resolution with your TV. Can you tell from the TV what resolution input it is receiving?

Also not out of the question that the 1K+ TV has a much better scaler than the $35 CCast! lol
TV can probably display the picture via DLNA at the Picture's native resolution where the CCast is scaling it to 1080P which on some images that are higher resolution would be compressed.

Try using this app second screen which let's you cast in your TVs native resolution

How will mirroring look with the 18:9 aspect ratio of the G6 and S8?

I would like to buy either the upcoming LG G6 or Samsung S8, but I'm afraid of how Chromecast mirroring will work with these new phones. Both phones have an ultra wide aspect ratio of roughly 18:9 in landscape mode, which would result in black bars on the top and bottom if mirrored directly to a standard 16:9 TV. What I'm *hoping" to learn is if the Chromecast app is smart enough to lop off the portion of the phone display that contains the nav buttons, which would conveniently leave a roughly 16:9 area to be mirrored.
Anybody know how this is going to work, and whether there are any workarounds to get mirrored images to fill the entire display area of a 16:9 TV?

"SecondScreen" - App for better mirroring of rooted devices
If you have a 16:9 TV and want to mirror the display of Android device which has a 18:9 ratio, use this app the app "SecondScreen" (https://www.xda-developers.com/cast-device-second-screen/) to set the resolution to 16:9 before casting to the Chromcast.
"Second Screen aims at providing you with a way to properly cast your screen so that it looks is best whenever you are showing it off to your friends and family. It does so by allowing for a user selectable resolution and even DPI in order to take full advantage of your TV."

UI Tuner
Pretty sure the manufacturers of those 18:9 2:1 PoSes will have this well sorted out, or at least they should.
It's already crappy enough to browse internet sh1te in 16:9 landscape with all of those squatter bars you can usually find in lots websh1tes (including THIS ONE, ffs).

Alternatively, you can select a more standardized 16:9 resolution via UI Tuner and then cast the screen.

have 2560x1600 tablet and 1920x1024 tv, with second screen app modifying resolution nothing happens, can only change over and down size only inside the 4:3 tv window, black lines ard almost there, does someone can help to solve?

Question Video camera cropped in on Android 12

Hi, I've run into another new issue with Android 12 and I'm wondering if anyone else is experiencing it. Inside the camera app, the video ends up seriously cropped compared to how it was on Android 11. Whereas before I could shoot indoor things (cat videos, etc) with the normal lens, now I'm having to go out to the ultrawide to fit things in frame. For now I'm getting around it by using a custom older version of Gcam, but I'd like to just use the normal app if possible. Is anyone else seeing this?

This is with the stock app:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Compared to how it was with Android 11 and on the custom Gcam app
As you can see, it's a significant amount of cropping. Both with the same standard stabilization enabled. (And pardon the messy desk)
I also tried installing the older 8.2 APK, but to no avail. It's older than the 8.3 that comes with the OS, so you can't go back further than that. And also my old technique for resigning apps to make the system think they're separate apps doesn't seem to be working, but if anyone could figure out a way to do that, I'm all ears.

It's normal. This how EIS works.

Did you even read? This is considerably more cropped than the same stabilization setting on Android 11. It turns it from perfectly usable to completely worthless. And if I'm recording 1080p60 or 4K, it's actually recording at less than full resolution and blowing it up, which looks terrible.

It is normal I think that is how it works.

I think I understand your question but I don't think I recorded any videos before upgrading to Android 12, so I don't have any comparison. I agree that the "1x" video on 12 has a narrower field of view than the equivalent "1x" still photo mode. Allso the video UI does not seem to have any option to disable image stabilization completely. I see that it offers .6x only for standard and cinematic pan. The other modes start at 1x or 2x, so I'm not even sure if the number always means the same sensor.

Yeah, I experienced the same issue, using exactly the same video camera settings the video on Android 12 has much narrower fov. I find it strange that no one is talking about this, maybe no one cares, but when making indoors videos it's a big deal since you have to switch to the wide angle lens, which gathers much less light.

The ultrawide camera also lacks autofocus, so if you're trying to film something close-up like a computer screen, it won't be in focus. This is definitely a major issue.

I just noticed that when you pull down the settings pane in the camera app, click "More settings", and scroll down, you can find a toggle to disable video stabilization. This gives a wider field of view and seems to show a similar lightly shaded on-screen control for stabilization. Trying to touch that control raises a hint to enable stabilization in the settings.
Are you sure that the Android 11 and custom app are enabled and not in this funny state with the partial shading of the control button?
