I have the same exact problem with my LG smart TV as Salamender,.... On our Nexus 7 wifi model, Wirless display > CERTIFCATION options here are Enable listen mode check box, Enable autonomous GO check box, WPS configuration, Listen channel, Operating channel
[Nexus 7 Android Development] s107ken:
ok, 120 secs option is invisible, it is internal settings added on 4.4

if certification on, adb logcat output has "120" string.
[Nexus 7 Android Development] struct:
Yes I can notice it was longer with this setting enabled, but still not helping. nexus just keeps saying connecting, then poof gone :( TV says connected, but nexus says connecting... I don't think nexus is sending data stream, other then connection packet

Also I don't see 'PAIRED DISPLAYS' like you have.

Is there anyway we could get the camera working? I had to switch to a CM 11 build with working camera. Is there any way to make a flashable zip with whatever apps, libs, system files that are modified to make this work? Your rom works great except for camera
[Nexus 7 Android Development] struct:
My LG has miracast built in, I don't believe it's a problem with the TV side, my TV has been reported to work with all other miracast device s... Also my TV says my nexus is connected, but the nexus just hangs saying connecting, then disconnects shorty after
[Nexus 7 Android Development] struct:
So sounds like a UDP protocol issue, LG must have a slightly different or newer protocol for Miracast, may have to capture the packets using a Samsung AllShare to nexus 7 and compare it to LG TV to nexus 7 captured packets... Does anybody know if the 2013 nexus works with LG TV`s?
[Nexus 7 Android Development] s107ken:
i tried create flashable signed / unsigned zip, adb push, flash from recovery,,, flash failed!

recovery is TWRP2.6.3.1 and clockwork6.0.4.3.

i'm googling to solve this.

Btw, is mirroring smoothness affected by the sink device? Because It's quite laggy for me. I'm using a cheap China miracast dongle.

+1...... Also get the ultimate rotation app from play store.
[Nexus 7 Android Development] ZenInsight:
Actually, I needed to unlock the bootloader, root it, and put the grouper image on. Then I adb sideloaded the miracast zip for grouper bootloader images.

Now Miracast does work. NOT through the wifi driect in the advanced menu of the wifi area, BUT using the "Miracast for you" app, you can choose "Launch Wifi Display Settings Activity", then connect from there.

It is pretty laggy right now though. If it was stable, I could watch something streaming...but it is intermittent...like suddenly the screen gets corrupted then it works again.

If the stability is fixed, this will be perfect.

I'm wondering if I can install the latest Nvidia kernel, but I'm pretty sure that some tweaking needs to happen on the code of this mod.

When I get a chance I will also make sure my PTV3000 is the latest firmware.

Thanks dev!
[Nexus 7 Android Development] gk1984:
Yes, very laggy but it works. I did notice it's pushing very large amounts of data when I looked at my floating network monitor app. The N7 averages about 15mbps upload via miracast while my HTC One averages 10mbps and is less laggy. I'm wondering if the amount of data being pushed is slowing things down.
[Nexus 7 Android Development] s107ken:
maybe HDCP error.

N7 doesn't have hdcp key.

some sinks can skip HDCP authentication, so HDCP contents disappeared.
[Nexus 7 Android Development] s107ken:
this zip for stock KitKat.

my ROM and flashable zip is mostly same as Source.

flashable zip didn't contain (p2p)Sink feature.
[Nexus 7 Android Development] s107ken:
thanks your analysis.

open Miracast for you app, checked force change fps, select framerate 10 or 20 hz,

then packet is lesser?

i didn't confirm this option's validity:p

Q-WH-D1: freeze sink? after connected.

in my old memory, Q-WH-D1 is more stable working.. :confused:
[Nexus 7 Android Development] bjcoenen:
The grouper mod doesn't work on my 4.4 Nexus 7 (2012 wifi) but the tilapia mod zip does (allshare cast dongle). Is there a trick to get it to connect faster because mostly it hangs on connecting? What are the best or correct settings to be enabled or disabled in the mira4u app?
[Nexus 7 Android Development] ZenInsight:
I agree with you!! 10-15 is way too much. It should be set to max at 4...or may be even 2.

2 is enough to push a 720P video. My PLEX app streams at 2mbps on Roku 3, and it looks perfect.
[Nexus 7 Android Development] gk1984:
I agree. I thought what my HTC One was pushing was high. But in all honesty, DVDs are typically encoded around 8 Mbps and blue rays are around 25 Mbps. I work with video regularly, day job and all. I find it unnecessary for the average person for such high bitrates but kinda makes sense why these are so high.
[Nexus 7 Android Development] s107ken:
Can you eat maguro raw fish?

in Japan, sashimi is very popular food.

and i'm debugging maguro(Galaxy Nexus), 10 inch hdmi display and Q-WH-D1(cheap dongle from china).

Q-WH-D1 with 32 inch TV: freeze, unstable

Q-WH-D1 with 10 inch display: brilliant working

this result is a next key?
[Nexus 7 Android Development] s107ken:
in Nexus 7 2012, didn't support "intra refresh mode" for hardware video encoder.

so N7 packet size is more increased other devices? :confused:

i don't know details of H/W encoder, video codec, etc.

next, i found that if bitrate reduced, then packet is lesser.

but Q-WH-D1 as cheap dongle from China is also freeze at minimum bitrate...

add bitrate change option for flashable zip.
[Nexus 7 Android Development] gk1984:
I wish I could try this some more. I'd like to test lower bitrates. I've jumped to the cm11 build and when I flashed the previous version, it killed wifi. Turning on wireless display broke wifi completely, even after a reboot.

Although... The apk you developed, is this specific to your mod or might it work on another device that already supports miracast? I'd like to try reducing bitrate and adjusting some settings on my HTC One.

By the way, I'm not asking you to support cm11. It's still not official and early. You're also still ironing out your mod for stability too. Perfect this before expanding. Just wanted to share my experience in case anyone else was curious about it working.
[Nexus 7 Android Development] ZenInsight:
Awesome. Testing now on PTV3000!

[Nexus 7 Android Development] ZenInsight:
Sorry it took me so long. I did try the new one which allows for changing the rate of data. It does work better! Much better actually. I can now get Youtube to stream smoothly videos and watch on my 47" Vizio TV throuh the NetgearPTV3000. But when I tried to play a game "Sparkle", it did not work. The lag was so bad that it was just a still image every 10 seconds.

Something isn't working right....but it is SO close!
[Nexus 7 Android Development] gk1984:
I'm not sure it'll ever be perfect. The tablet has to create an mp4 stream of the screen on the fly and then send it via wifi direct to the receiver. Adding extra work, like playing a game, strains the CPU and other hardware even more. Miracast isn't even great for games on my HTC One.
[Nexus 7 Android Development] Reiven89:
A working miracast feature would be amazing, please keep testing and improving to find the best compromise with quality and stability, thanks for your work

I just buy an Asus Miracast Dongle and its working well with Nexus 7 wifi (grouper). Thaks you very mutch for this patch.:D

I hope google will oficially support miracast on grouper. Kensuke prove it can be done. My respects!
[Nexus 7 Android Development] gk1984:
Not sure how much this will help but try reducing the bitrate in the miracast app the mod includes.

Miracast is basically encoding and mp4 video stream on the fly and sending it over wifi direct. If you're doing anything that would work the CPU extra, you could slow down this mp4 encoding. Lower bitrate would help if the network needs more bandwidth.
[Nexus 7 Android Development] droidbreath:
Thanks for the reply!! And I saw that my TV connects using Intel's WiDi, when I turn on WiFi Direct, but nothing's happening from "cast screen".So is it using WiDi or Miracast?
[Nexus 7 Android Development] kegobeer:
WiDi is an Intel wireless + Intel processor display system. Any other wireless + processor combo must use Miracast.
[Nexus 7 Android Development] gk1984:
Widi is Intel's wireless display technology. It's similar to miracast but not the same. Many Widi capable devices have been updated to support miracast but Widi doesn't equal miracast
[Nexus 7 Android Development] zard:
Pardon my ignorance. So is it correct that other than the Rom with Miracast source files, I still need the Miracast dongle?
