[Q] Does Nexus 4 support HDMI-CEC via Slimport? - Nexus 4 Q&A, Help & Troubleshooting

According to the slimport specifications, the protocol supports HDMI CEC.
I'd like to know whether the Nexus 4 can be controlle via CEC, thus play/pause/fwd/rev using the TV remote, especially with Googles Play Movies.
Anyone tried yet?

I noticed this as well when I ordered my slimport adapter a few days ago. According to the xbmc wiki, "some Android devices support cec [1]".
A google query led me to an Android source file that references CEC quite a lot. It has MSM in the name, which refers to qualcomm. It seems that there is at least some qualcomm chipset that has some form of support for CEC in Android. No idea if this code is actually working however.

will we ever get screen mirroring?

From what I understand, Miracast support is off the table due to the wifi hardware on the current gen of nexus tablets. With that said, do we expect to ever get screen mirroring support through WiDi, the pogo connections or the micro usb port?
I know that these guys, http://esrlabs.com/ , had created a custom rom for the n7 and raspberry pi such that the n7 could screen cast and the pi would recieve. However, I reached out to the developer and understand that work has ceased since Miracast was announced.
If the consensus is that this capability will not come to CM/AOKP in the near future, then I'd like to sell my n7 and get a tablet that does or will support mirroring (i'm willing to invest on hardware on the reciever side - but between the tv, xbox, cable stb and raspberry pi I'm finding that my home theater receiver is running out of spare hdmi inputs /firstworldproblems ). I do not want to invest in a 1 off product that is not a standard, like a MirrorOp receiver.
So what are your thoughts? Is something coming to the N7? If not, what hardware and software should I get instead?

Ant+ on nexus 10

If I understand it correctly, ant+ is the same 2.4 GHz as wifi and I see there is an ant+ driver on the play store. So will ant+ networking work on the n10 (or any android 4.2 tablet) or is it something the manufacturer need to hardwire into the hardware?
I have several devices including several heart rate monitors and a bike cadence / speed sensor I would like to use with my tablets. I use them on another android device and the frequency is there... So there should be a way to get then n10 to recognize it?
Ant+ driver on play store: https://play.google.com/store/apps/details?id=com.dsi.ant.service.socket
Anyone got ideas or a solution.?
Thanks!
The 2.4Ghz band is used by many different wireless products (ANT+, Wi-Fi, Bluetooth, cordless phones, car alarms etc), but they will not run on your tablet without the correct firmware and drivers to run them. The N10 does not have ANT+ firmware or drivers (there's a list of devices on the Play Store page you link to) on the hardware it includes. So yes, the manufacturer must build a device that has ANT+ built in to it.
However, you can still use ANT+ on your device. As the N10 supports the USB Host feature, you should be able to connect an ANT USB stick with the ANT USB Service (play.google.com/store/apps/details?id=com.dsi.ant.usbservice) and a USB OTG cable.
Hopefully this is a solution which works for everyone until there are more devices available with built in ANT+!

Using the otg+USB on the N10 is an option at the gym on a stationary bike or stair climber. Just have to be REAL careful about the USB port and doing any damage. Using it with my Samsung Tab 2 7.0 and my bike would be a little trickier since I have a weather-proof case that mounts to the handlebars. Getting a USB stick or cable into it would not work. Such a shame since there are so many great sport/fitness programs for Android that do support ant+. A little surprising that Google would note code it into their hardware since they are all about tracking/obtaining data.
Could it be done with a custom ROM or is it even deeper in the hardware?
Going to have to do some real hard research for my next tablet.... Find something that does it all?
Thanks for the insight!
The N10 ANT+ hardware has been enabled with the "ANT+ Enabler": http://forum.xda-developers.com/hardware-hacking/hardware/ref-devices-ant-hardware-t2879990

[Q] List of Android hardware with OTG support

Hello,
I am looking for list of hardware that supports Android, but this hardware needs to support OTG.
Is there a web site that has list of all the Android phones/tables that support OTG?
To be specific I am looking for something that has 4/4.5 inch screen and OTG.
Anybody knows if the new Motorola G phone supports OTG, I looked at their spec sheet doesn't call it out explicitly, where as Nexus 5 explicitly lists OTG support.

USB TV Stick Adapter + Micro-USB adapter for Nexus Player

Hey all,
So from what I understand, one of the few ways to get over-the-air live tv with an HD antenna on your Nexus Player is to get an HD Homerun or comparable device that transmits the signal over DLNA to your devices. This is a little over-kill for me, as I just need live tv on my Nexus Player. Is it possible right now to use a USB-to-Coax TV Stick (like this one: www(dot)hauppauge.com/site/products/data_hvr955q.htm ) with a usb to micro-usb adapter? Any reason why this won't work?
Best,
Sheik
The link you posted above (when manually corrected) leads to a 404 error message. The correct link is http://hauppauge.com/site/products/data_hvr955q.html. Does the product's web site list Android compatibility? I doubt that it would work as you have planned but I wonder if it *might* be possible because they apparently support Linux (which is similar to Android). The Linux tab lists an e-mail address which you can contact for "customization of the Linux driver" so maybe that's the person to ask. Is there a reason why you don't just plug the OTA line directly in to your TV?
I was hoping to use the Live Channels function on the Nexus Player, OTA works fine in the TV, but having one box for everything appeals to me

Cannot play Netflix with 4K @ 60hz for HDMI

I just switched to using a new TV over the weekend that's (finally!) 4k.
If it matters, the TV is the bleeding new Vizio P65-C1 also a good write up on the TV can be found here.
When I plug the Shield TV directly into the TV via HDMI and go to the Shield's settings then HDMI, it detects and shows (Recommended) next to 4K 60hz, which is what I set it to.
I can play YouTube 4K videos, I can watch anything I want without issue on Plex or Kodi, I can play all of my usual Shield exclusive games like Doom 3 or Portal without issue but for whatever reason, Netflix will just not play anything. Not just 4K/UHD content, just any content. I can move around through the Netflix menus and browse for what I want to watch without issue but when I try to actually play something it has no audio and freezes and might jump forward in broken increments or will be 100% frozen on the screen. I can stop it without issue and the app is otherwise responsive and not frozen.
I can Cast Netflix content to my Shield TV and it works without issue also. Correction, I cannot cast Netflix to the Shield TV. Same issues as trying to play locally. I was accidentally casting to my TV directly, which does work without issue. Both my TV and y Shield TV are hard wired to my router directly via ethernet.
It's only when I try using the Netflix app that is built-in.
The thing I noticed when I Cast vs the native app is it shows a loading progress screen and can take a few seconds depending on the contents quality to hit 100% then start playing. It seems like the native Netflix app is not trying to cache the content and seems like it's trying to direct stream it, which it cannot keep up with for some reason.
The same happens with cartoons, older shows that at best are available in 1080P like X-files or of course UHD/4K content. There is no different in the behavior between the different source videos in the native app.
I have already created a support request directly with Nvidia but wanted to see if others have encountered this as well and have any suggestions on what I can try to fix it?

Hey man... Finally got some sun in Atlanta?? What a nice day....
Anyways...see the link below I answered for somebody else, see it applies to you. They key is HDCP2.2 compatible equipment all along your video signal, Shield (which is), receiver, TV input. If any isn't, it won't work.

It was a beautiful pollen coated day today
I checked and sure enough the TV does support HDCP2.2. Though it also notes that while it's HDMI 2.0, it's not enabled yet and will be coming soon in a firmware upgrade. Makes me wonder if that'll fix this once it's available.
I'm still going back and forth with Nvidia as well but so far nothing other than answering some questions and sending them some logs.
From your TV user manual:
When connecting a HDMI 2.0 device, HDMI Color Subsampling needs to be enabled to support 4K resolution at 60hz.

Statement not correct... It support HDMI 2.0 out of the box. It's the HDMI 2.0a support that will be coming via a firmware upgrade.

Ah, good catch. I'm not as up to date on the HDMI specs/standards these days.
I'm guessing then that HDCP2.2 should work out of the box though but will contact Vizio support to confirm.
Just curious...have you tried different HDMI inputs?
"The new P-Series models will include: four HDMI 2.0a/HDCP 2,2 inputs, plus one additional HDMI that handles 4k/60p at 4:2:0, although it is listed as HDMI 1.4, Vizio told us. The HDMI 2.0a inputs will allow the Vizio displays to connect to new Ultra HD Blu-ray players to stream 4K with HDR10 metadata, something earlier Vizio 4K UHDTVs have lacked"
Are you connected to that "one" input?

According to Vizio's support "The tv supports HDCP 2.2 on all HDMI ports" so I'm not sure. The manual does not detail specific ports at all for HDCP.
@reTARDIS I just bought the same TV and am seeing the same issue. I noticed that if I change the Audio setting for the show I'm watching from "English 5.1" to "English" the show streams correctly. I'm not sure why this is happening either.

Interesting find. I'll test that on mine this evening.
@oracleicom I just tried this and confirmed it works for me as well. I send an update to Nvidia with this info to see what they have to say. Thanks for the workaround. It's not perfect but will do for the short term.
I would make sure you have a HDMI 2.0 cable (18Gb/sec), that's the only one that supports 4K @ 60fps with 4:4:4 chroma (color).
Use a port on the tv that supports HDMI 2.0.
I am having the same issue with Nvidia Shield and and the same TV. I was so excited when I got it today. I can also make it go with changing it english from 5.1. I had the Shield hooked up to a previous Vizio 4k TV and there was no issue. I am talking to Vizio support now and they want to blame the Shield even though it works fine with their previous 4K TV.
I also tested with my Nexus Player and it has the same issue.
@reTARDIS Did you ever get a reply from anyone at Vizio or Nvidia? On mine, everything but Netflix works fine, so maybe it is something that Netflix can fix in their Android TV app.
Correction, both Google Play Movies & TV and Netflix have the issue. Nvidia is saying it is Vizio's issue and Vizio is saying it is Nvidia's issue. I pointed out the Nexus Player has the same issue with the new Vizio and they have not replied.

They've really not given any indication that they have a clear understanding on what is happening and every time I ask for an update, if they reply at all, it's just to say that they're still researching the issue.
They recently suggested that I test the following.
SHIELD TV HDMI out -> Vizio P65-C1 -> Vizio P65-C1 HDMI ARC to Pioneer SC-1522K
Initially, I didn't think this would work as I had thought TV's did not output anything via HDMI and could only input but after doing some further reading today into HDMI and ARC, I think it might work to output just audio from my TV via HDMI to the receiver using one of the HDMI ports that supports ARC but I have not yet tried this.
As a backup solution, I just ordered this USB to Optical audio adapter last night that others have said works with the Shield TV to output audio via USB to TOSLINK. The device includes a TOSLINK to SPDIF adapter. I plan on just using this to output SPDIF directly to my receiver to bypass the Vizio TV to see if this resolves the issue or not. I will update later once I've tested it out.
I'll report back my findings with both test.
Update: The same issue exist with the USB to SPDIF/Optical adapter straight into the SPDIF/Optical input on my receiver (bypassing the TV for audio).
I'm at a loss for what to try next and the issue has not gone away.
Update: I figured out how to make ARC via HDMI work from my TV to my receiver over the weekend and am now only using audio out for all devices connect to my TV via HDMI then out via the ARC HDMI port on my TV (HDMI 1) and into the ARC input on my Pioneer receiver. While audio works without issue for any connected device and the Shield TV in general, the same issue exist as before with 5.1 audio playback from Netflix on the Shield TV.
I also did a factory reset on my Shield TV this past weekend but sadly it didn't change/fix the issue which still persist.
I just cast to my TV now for Netflix and avoid using the Netflix app on the Shield TV.
