[EXPERIMENTAL] Enable Mirroring from any device

[r3pwn]

Hello, fellow XDA members!
Some of you may have heard of me before, and for the ones that haven't, let this be a warm introduction.
After hearing of the new Chromecast app with Beta support for mirroring, I decided to see if it's possible to enable for all devices. Apparently it is!
I assumed that some devices just wouldn't stream well, so I decided to mark this as [EXPERIMENTAL]. Please note that I did not make the feature, just the method to enable it.
Please alsenote that you need the latest version of the Chromecast companion app and root access on your device (not your chromecast) for this to work properly. The mirroring functionality requires KitKat 4.4.2 or higher.

Please note that under certain circumstances, some Samsung tabs may bootloop due to this modification. To be safe, do not enable the second option unless you ABSOLUTELY need to.

If this worked for you and you want to send some money my way (Keep in mind that I didn't make the mirroring, only the hack to enable it), feel free to visit my PayPal donation link in my signature.


For those STILL having issues,
Check /system/lib/hw directory for the file "audio.r_submix.default.so".
If it doesn't exist, ask your device maintainer to add audio.r_submix.default to
the product_packages in the device.mk file. (You may not know what it means, but they will.)

(Thanks, @hwong96.)

What exactly is required for this to work?
(This is the technical aspect of getting mirroring to work)

(Straight from Google)
* The WiFi radio must support WiFi P2P.
* The WiFi radio must support concurrent connections to the WiFi display and to an access point.
* The Audio Flinger audio_policy.conf file must specify a rule for the "r_submix" remote submix module. This module is used to record and stream system audio output to the WiFi display encoder in the media server.
* The remote submix module "audio.r_submix.default" must be installed on the device.
* The device must be provisioned with HDCP keys (for protected content).

Please note that I tried to provide a safe, universal fix, but unfortunately, this may STILL not work on some devices. If it does not work for you, let me know and I will try to fix it (again).
Please note that this has the potential to mess up audio on your device, but it creates a backup that you can restore from by "Disabling" the fix.

To enable Chromecast Mirroring on a TouchWiz ROM, follow the guide below:
(For SAMSUNG Devices ONLY!)

Go to system/etc/wfdconfig.xml
Find the following lines:*

1*(Change this 1 to a 0 and reboot)
WFD_HDCP_2_1 
6789
0

For those with audio issues after applying the Force-Close Fix:

DISABLE THE SECOND OPTION IN MIRRORENABLER FIRST!

I'll explain it in a way so you can edit the audio_policy.conf file yourself. The audio_policy.conf file is unique to each model in a manufacturer's lineup and between manufacturers. That is due to the different audio hardware installed on the device. It is more prevalent in older devices, not so much in newer devices. The force close fix option #2 in MirrorEnabler is more of a generic fix.

If you are up to the challenge, here are the steps to edit your own audio_policy.conf file-
1. If you applied option #2 in MirrorEnabler, de-select and reboot device to reset the manufacturer audio_policy.conf file.
2. Make a backup of the manufacturer's audio_policy.conf file in the event you need to restore it.
3. Open your audio_policy.conf file.
4. Open the this pdf file and copy the red highlighted words from the global configuration section. Paste into your global configuration section as shown. Make sure to include the pipe.
5. Copy the r_submix section highlighted in red and paste into your file as shown. You should have 4 }s at the end. Sampling rate should be 48000.
6. Save your file.
7. Reboot.

Use MirrorEnabler without selecting option #2. You no longer need it if you edit your own audio_policy.conf file.

You now have your device manufacturer's audio_policy.conf file with the audio.r_submix module added. You still need to make sure the audio.r_submix.default.so is baked into the rom. Look in /system/lib/hw. On newer devices look in /system/lib for libaudio.r_submix.default.so.

Not much more I can say.

Works!

Can you stream properly? If so, please be sure to hit that thanks button and tell all of your buddies!

My S3 running quantum makes the attempt but then it said "Google services has stopped" then just says disconnecting.

AT&T Samsung Galaxy S III

 

[cnotes2019]

Does it still have to be running at least 4.4.1?

Sounds like it *might* be a hardware limitation. I don't know how to help, sorry.

I have honestly no idea. All of my android devices are running KitKat, so I wouldn't even be able to test. My guess is probably, but you can feel free to go ahead and give it a shot.

 

[ksd316]

No worries, glad to provide a test.

Just tested on Verizon M8 running Skyfall ROM (almost stock) and works pretty well. There was a little lag in places but not bad for an "experimental" workaround.

Thanks!

 

[r3pwn]

I started setting up a list, as they come in, of devices that this does/doesn't work with. Please, as you test this, leave what device you are testing it on, ROM, and whether or not it worked.

You are a god

HEY MAN YOU JUST MADE MY YEAR. I have been stuck on terrible TouchWiz Stock Roms on my Galaxy Note 2 for the past 1.5 years because I use my screen mirroring with allshare cast dongle a lot. I have been trying EVERYTHING to get screen mirroring or cast screen to work on this device for over a year. When I heard it worked on the CCast I pulled out my Nexus 7 2013 and it instantly work perfectly. I was so bummed when I saw the Note 2 was not on the list of supported devices. I just installed your app then the sqlite binary from the playstore and used that to install the binary. Then enabled your app, launched chromecast and am now mirroring my screen FLAWLESSLY on my US Cellular SCH-R950 t0lteusc Note 2 using stock rooted deodexed 4.4.2 TW rom and latest agni-kernel. YOU ARE THE MAN. Seriously, thank you so much. Seriously. You have freed me from the samsung prison.

I went ahead and added the Note 2 to the OP.
EDIT: Perfect timing, too!

Great find!!

AT&T Samsung Galaxy S3, KitKat 4.4.2 stock rooted.
Works, but with no audio.

Overall performance is pretty good. It seems just a tiny bit slower than AllShare Cast (to AllShare Wireless Hub), I'd say 0.5 sec lag on Chromecast vs 0.5 sec lag on AllShare Cast.

Video playback of local content using the stock video player seems very comparable to AllShare Cast - in fact, I can barely tell the difference aside from the lack of audio on Chromecast playback. I wouldn't be surprised if they share the same base with just slight tweaks.

Chromecast seems to be a bit more tolerant of other network operations compared to AllShare Cast.

I'm very impressed by the quality of mirroring. If the audio worked, I'd be very tempted to use Chromecast mirroring over AllShare Cast.

I have just test it with Galaxy S4 running CyanogenMod 11 M8 the video is perfect but the sound something wrong with it like a baby sound :laugh:

 

[H-KaN]

Working on the LG G2 with CM11 M8. A bit laggy for me though. But thanks very much!

 

[pbailey212]

It does not work with HTC evo 3d. I know, its old but it won't break.

Done, seems working fine on my z2.

 

[Idan73]

Working on note 8 wifi tab. A bit slower than sgs5 and LG g2. Otherwise perfect ?. Not really for games, because of that lag, but great for just general stuff.
