Is it possible to have a virtual camera in android? - Android Q&A, Help & Troubleshooting

Just Like obs-virtual camera in windows.
I heard sharing audio input via multiple apps is possible.
I know 2 apps cannot directly use camera simultaneously.
Can an A app that is using camera send the video stream being taken to another camera app( i”ll call it B)??
So when user click that B camera app, video being taken by A app shows up and it seems like B is using camera but actually B is just showing the video that A app is taking that moment.
And in this case when i click recording button in B app, recording will the video be recorded?
I wonder it could possible if i build both a and b apps by myself.
If android doesn’t allow it.. What if the phone is rooted or using custom ROM?
as far as i know, there are linux and windows custom rom that are not based on android source .
And of course , these ROMs can be installed and run in android phones.
There are apps that helps to live stream on multiple platforms at sametime from phone.ex) streamlabs Does this imply the answer to my question is yes..?

Android on HD2 video

Hi Leo Users,
I am considering buying this phone but I need to see how well it handles in android.
Can someone post a video using one of the most recent and more working roms? I want to get an idea of how well it goes.
1. What is currently not supported on the leo?
2. Does all of its ram get ported in android or does it use only a smaller part?
3. What about the camera? Is the camera app using the camera to it's full potential?
4. Video playback? Does it play hd?
5. Is a nand installation of android possible?
Thank you!

1. For each Android distro out there it says in its own topic what's working and what it is not. I know it can't record video in HD 720p.
2. As far as I know, Android uses all available RAM.
3. There are still some issues with the camera, mostly because improvements are still made to native Android phones. I doubt you will use the camera like that. I don't consider it a low point.
4. Video playback is really good and it also plays HD. I tried with some Youtube HD videos and they were ok. Haven't tried with a computer encoded fully fledged HD. I know that there are video players on Android Market that can play all Xvid encoded videos out of the box. Just copy it on the SD card and you are set.
5. At this moment, NAND installation is not possible. There were some major improvements done and I think it will be possible to be functional at some point.
6. I would add the fact that HD2 can run a lot of Android flavors because it can launch them from within WinMobile. This is something you can never achieve with a native Android phone.
7. Battery drainage is still heavy. Every day something new is discovered on how to improve battery life.
I see you own a Wildfire. HD2 is a lot better that it. I read it on a Romanian tech blog, an editor made a comparison between native Android phones and HD2.

[Q] Skype

Does anybody managed it to get Video Calling working on the viewpad 7?!
I have no luck, no matter what custom rom or kernel I use, theres no video option in the settings...:-(
So far...happy with my rooted Viewpad on 800Mhz
Sorry, wish I could bring you better news, but I haven't been able to get it working either. A bit surprising considering the front camera, according to Skype they will support devices with front camera. Is it the lack of Flash support that blocks its usage?
Hi Im as well not able to use video calls on Skype on Viepad7,Now there is a new ROM and some Flash 10.1 that was hacked to work on our old ARM processor) maybe this could help...Durring weekend I should be able to test this ROM but looks to be ok...

fring
use fring works with front camera
but there s no more skype support in fring, afaik... ;-(
Sent from my ViewPad7 using XDA App
Anyone got news?
I do not understand why there is a frontal camera and no software to use it
The way I understand it, it's Skype itself that does not support it, our viewpad should be able to handle it.
Problem would probably in the Camera API that does not properly support calls to the front camera, that was only added in android 2.3
Would be nice if someone could test some video calling apps and let us know what works and what does not. I'm curious to see if there are any implementations that can acccess the front camera from 2.2.2
App's name viber can video call from front cam, may be cause microsolf buy skype and don't want to develop good app for android I think. Hahahahaha

Background Video Recording App?

I can't seem to find an app that records video in the background on my phone. I am running Task650 and Ktoonsez's AOKP build 6.8.12. I have tried Secret Video Record, Mobile Hidden Camera, Hidden Camera Spy Camera Free, and a couple others. These don't record video in the background correctly. The videos come out scrambled (with green lines usually). You can tell when the camera is being moved but you can't tell what is being recorded at all. Does anyone know how to fix the problem or of an app that works?
That ACLU secret recording app might work. Don't know if it saves video locally or on their servers though.

I am having the same problem. The video won't even play for me. Everything else works, just the background process causes it to screw up.

That's because Android does not allow recording video without showing preview (SurfaceView) to the user. When you hide preview and Android detects it - preview surface will be destroyed. Furthermore then surface is not longer valid - MediaRecorder (which records video) will crash.
All those apps try to overcome this restriction in different ways.
I've also tried to do it and published app: Hidden Video Camera.

I've tested on bunch of different devices and it worked like a charm. You can try it for free and check if it works on your device.

video recording while playing music not working

hello z2 users!!.
recently i bought my z2 in replacement with my old N7000 note1. i used my note 1 in recording video of myself playing guitar and at the same time playing MP3 backing track on the same phone. i have tried that features on other phone like lenovo and its working fine. i like this kind of feature where in our phone is a multi task.
when i test it to my Z2. play the music on the walkman app, minimize open the video camera. and start recording suddenly the music stops. i tried the other way around, open camera app, start video recording, it stop upon minimizing the camera app.
Now my question is:
1. is this a common issue of Z2? is it normal on sony phones.
2. is there a way that my phone can use this feature?
i hope i get reply on my queries as i am hoping to use the phone like this

That's normal on Sony phones. You can try with some other camera app like Google camera.

thanks for the reply man, i have tried the google camera but still same issue. btw i used CM rom in my N7000, its working.
Maybe CM rom of Z2 will work or it may give the same output as the stock rom.

Maybe, but you must try it. So if this function is important to you unlock your BL and try with CM.

Screen Recorder that Doesn't Lock FPS to 60?

I have been looking for a screen recorder that can not only record internal audio (even for some apps that don't natively support it like the built-in Samsung screen recorder) but would also not cap my frame rate at what is apparently 60 FPS but looks more like 48 FPS. I am not sure why recording with the built-in recorder is so choppy when all it should be doing is recording at 60 FPS. I understand that recording at 120 FPS is kind of unreasonable for a mobile device, even one of this caliber, and that is not what I am asking for. All I want is to be able to screen record 60 FPS videos while having the smoothness and responsiveness of the 120hz display. I could just use the built-in one, but with that FPS cap, it makes anything I attempt to record feel choppy and makes the tablet feel not as responsive.
The one app I tried that seem to fit the bill was this, but trying to record with internal audio enabled just crashes the app. This is also probably because of Android 12. A lot of other apps either try to lock internal recording behind a paywall or do not record the inernal audio at all for some apps (but it would record just fine with the built-in samsung recorder).
I am using a rooted Tab S7+ with Android 12, but I could flash Android 11 on it (for better compatibility with more apps). I sadly cannot flash Android 10 since I have a U2 bootloader, and all Android 10 firmware for the S7+ are for U1 bootloaders (as far as I know). From what I've heard, downgrading bootloaders is not possible. ;-;
Now, with all of that being said, if any of you have any recommendations for screen recorders that allow you to use the 120hz display while recording internal audio, or have any fixes or workarounds for the official Samsung screen recorder, please let me know. This is one of the very few issues I have with the Tab S7+, and for all I know, there is a solution for it, I just do not know it yet.

I tried using this one but it doesn't seem to record the internal audio for the games I wish to record audio in. Do you know of any workarounds or something I can do with root to be able to do this?

This is doesnt seem to work either. The plugin app requests root permission and asks me to reboot, but when I do, the option never enables. The internal audio option by itself also doesn't seem to work.
Have you oneplus?
Look this feature.
I sent screen recorder clip to you.
Oneplus has very good screen recorder.
You can change microphone sound and frame 60+ and definition and record from front camera and record system sound and show touches and video coding format and is an open source app.
Only oneplus phone, can download this app.
I can edit manifest and java (dex) to work on all Android phones.
