controlling HDMI

As stated in the (www .blogtalkradio .com/motodev) Q&A session yesterday with Motorola about the Droid X, in answer to the question asked at the 29:00 mark,
"The only time that we are enabling the HDMI driver on the device is when you are in the gallery mode. [...] The HDMI driver is not active any time outside the gallery," where the "gallery mode" is their included photo/video viewer.
I'm wondering how true that is...
(www .pcmag .com/article2/0,2817,2365630,00.asp ) PCMag's review stated that the youtube player and blockbuster player were not able to use the hdmi out at all.
As seen in (forum.xda-developers.com/showthread.php?t=703111 ) this thread the evo 4g, which also has hdmi out, is capable of allowing any app that uses VideoView to utilize that output, but that's supported by the phone maker.
Will that usability be true on the droid x?
Could we figure out a way to bypass any limitations Motorola includes, and maybe even send (an upscaled version of) the main screen through the hdmi (not just video but anything we could put on the phone's screen)?

I was just at a motorola event and we were able to run nfl mobile through the hdmi.
Yes the tv was in an ice sculpture and yes it was connected to a droid x via the hdmi cable

That's great news, thanks for letting us know!
The more apps with handshakes to the hdmi-out we have, the better for us to get it working completely openly
The whole media-center-and-phone-in-my-pocket is just a great idea imho...
With the hdmi out we could:
put any videos and pictures from any source up on your home tv
connect it to the projector at work and give presentations
go with a few bluetooth controllers to your friend's house and play multiplayer (even online) games on their tv with minimal cords to deal with
maybe even video-chat would be possible if you set up the phone with the camera facing out in front of the tv
... ok, that last one sounds like a pretty lame way to get video-chat, but it would save on having to have a computer/monitor/webcam when you wanted to
Of course this is all far into the future stages of development on the phone, but I'd rather create buzz and excitement to build up a developer and user base

Talked to a moto rep, said it might have been a beta device as licensing is what will prevent this thing from being turned on when it hits consumers hands. At least we know it can be done.

no fun, i'm not much of a C programmer, but if it's just enabling or disabling the driver, I guess it comes down to the security on the phone. If you go into root, I suppose we should be able to start the driver. The only thing I fear is if the driver is signed and only a signed application can access it, then I think we might be SOL

I'm not particularly worried... if we get access to enough apps that use the hdmi driver, we should be able to document enough of the method.
I believe while the hardware can reject unsigned versions of the OS (roms), most apps are self-signed (see developer. android. com/guide/publishing/app-signing.html) so that shouldn't be a problem. We just have to figure out which hoops to jump through (following the programs that use hdmi) to get it to work. They'd have to leave the hoops pretty wide open or else risk the need of updating the thing every time a new app is released that needs to get through.

This is a mixed bag here. The reason why Motorola limited the hdmi driver is likely so they didn't have to put a fps cap on the droid x like htc put on the evo.
This is pure speculation here but I would imagine the way that the evo devs are going to "truly" overcome the fps cap is to mimic the droid x behavior of toggling on and off the hdmi drivers so that the evo can access up to 60 fps.
You guys are on the other end of the boat where by default your fps won't be artificially capped, but you likely won't have full access to the hdmi drivers at first.
I think the sweet spot for both phones is finding a happy medium where we can toggle the hdmi drivers at will.

Any news on this? I would really like to get rockplayer and youtube working through hdmi. In fact, I would like to get the entire OS through HDMI and possibly a bluetooth keyboard and mouse working so I can use it as a little media center pc.

2 way control
I would lime to see this pushed to.the level of controlling the phone through an hdmi touchscreen.

I thought we would be able to see pandora and other apps through the hdmi...This sucks the way it is...also does anyone think the sound is terrible through the hdmi?

There is no point int he HDMi at all if you can only use it for your pictures and your videos from the phone's camera.
They need to make it show what you see on the phone, but on the screen
I remember there was a windows mobiel program that popped up a small window on your desktop that let you see your phone's screen and interact with it on your monitor when connected through usb
anything like this for android?

NO, the hdmi dock is a half ass design. For the $, it should do everything. MOTO/VZ dropped the ball on this. Hopefully they will open this up with a sw update.

Update: "Real HDMI" in the market
http://forum.xda-developers.com/showthread.php?t=769990&highlight=control+hdmi

Hi,
I'm pretty new to Android development. So my understanding after reading a couple threads here is that HDMI access on the stock Droid X is limited to the gallery only, is that right? And the point of the "Real HDMI" app is that it will automatically redirect all output to the phone's display through HDMI, right? So no API exists which gives programmatic control over the HDMI port? That's a shame if so.
Do any of the Android devices allow easier HDMI port control or do we need these kinds of work arounds for all of them?
Thank you very much for any information anyone can provide.

Sorry to be a pest, but can anybody answer my questions? Should I consider posting somehwere else?
Thanks again.

Maybe try posting in the Real HDMI thread over at DroidXForums.com because username GMAN (who made real hdmi) has a thread there. I'm sure his knowledge of the subject is pretty extensive.

[TT] Peripherals possible?

While looking around my phone I came up with a couple of thoughts. First would it be possible to make devices that plugged into the miniusb port on the top of the phone and could it be plug and play? Heck maybe even make the driver if necessary built into flash memory on the new device. It seems like it just takes an kernel update to make something like this possible if it's not already.
The second thing I thought of is if the above isn't possible, why not create an attachable mirror that sits at the right angle to take advantage of the rear camera for video chat. You could project your image onto the mirror and the camera could catch that. The top idea is alot better, the bottom requires alot less knowledge. Either would get us video chat.

Interesting, i like the first idea.

I like the first idea, though for video chat I would rather someone figured out where to pick up the actual modual that goes inside the phone (there's a thread about how they left the mounting brakets in place for the front cam.)
However for other things, like maybe a gamepad+extended battery combo, or an IR blaster to operate my TV

This is the thread you were talking about.

From what I understand about micro usb is that there are five wires/confections. The outside connections are ground and power. The two next to the ground are for data (one + and one -) and the last one next to power is a identification connection. If the wireis connected/has power then its a source device (i.e. computer). If its not, then its a peripheral (portable hard drive, out in our case, our phone). Its been a bit since I read up on that, so it might be vice versa.
Last time I tore the phone apart, I didn't look, but it may be a setting that is hard-wired (literally), or its a switch controlled by software. If it's the latter, then its possible, if its hard wired, then its not.
Adding things to the kernel or loading drivers isn't cut and paste. It takes available source code, which isn't always available, for both the phone and the device you want to use (that works with android), as well as understanding of how to make it work.
That last part I am not well versed on. But we have a couple devs trying to get the vibrant opened up. They are few, and the request list keeps getting larger.

I was just thinking today that it would be great to have a micro-usb device that could house a camera for video chat... I like your mirror idea...I'm prius owner and that's how the dashboard works. The usb is right there...really I think someone should incorporate a device in a mod of the back cover...i don't know anything about code but I could make the case.
Sent from my SGH-T959 using XDA App

Devices require a driver of some kind so the controller knows how to talk to device. For example, if I wanted to hook up my DSLR and control it, I would need a driver ported over and then the SDK for the camera would have to be ported over. An OS like Windows 7 has literally thousands of drivers built in and many other devices require you to install a driver. The only time "plug and play" actually works is either with the OS has the driver already installed or if the device is designed around a generic driver.

Incredible idea! I'm going to make the second idea. I have my own twist on the concept but it shouldn't be to difficult.
Sent from my SGH-T959 using XDA App

I like the first idea but I also had a similar idea and I'd like to see the attached camera come with led's and somehow acct as a flash for both cameras. It could be tiny, if the camera app could be figured out to trigger the flash on all galaxy s models, well at least the vibrant and captivate this could sell.
If a third party app was developed it could be added to any android phone in theory. If that third party app was as good as the galaxy s stock camera app then you'd really be in business.
If I was talking to my brother I'd have tried to convince him to help me develope something. Well I hope one of you talented devs has success with this idea. I'd also like to see success with the guy adding the extra camera internally, I'd be interested in performing the mod if the software end is figured out.

I can take or leave peripheral support, but I'm DYING for USB host mode!

That's the thing, devices that support USB host generally don't use a mini/micro B port. They have specific ports for that. Of course, the USB controller in there may well be able to be a USB host, but we don't know how to enable that from what I have seen. IF the controller can be put into host mode, loads of options like this become possible. It would require kernel mods, but that's not a huge deal. However, as long as we are in USB client mode, the only things we can connect to the port are chargers and computers, as that's all the phone knows how to deal with.

Makes me wonder if you can still take power off of the port and communicate to the device via blue tooth. But I don't think it would come to that.

Oh, it's host mode built in already. One of the major pluses that I weighed in on when buying the phone.
"Both the S5PC110 (smartphone chipset) and S5PV210 (its netbook alternative) are optimized to ensure long battery life for mobile devices, using a 45-nanometer (nm) Low Power fabrication process and low power architectures. With the 1GHz clock speed and 512KB L2 cache, these processors should also manage to provide performance unknown to the ARM world so far.
The two processors have built-in 3D graphics engine and support 1080p full HD video playback and recording at 30 fps. The final nice features of the new chipset include a wide variety of interfaces and peripherals, including HDMI 1.3and USB 2.0 host interface."

Hate to kinda go off topic with the USB Host mode stuff again, but it seems like since the interface is built into the chip, host mode should be enabled in the kernel.
Yes? No?
Has anyone tried to get an OTG cable in there to see what happens?
Just saying.

I've been curious about this since I saw it done (rather impressively) by sonic7406 (YouTube) on the Nexus One. Since then, I hear it's also been hacked on the Droid. From my research, I'm pretty confident this should be possible with the right drivers installed on the Galaxy S series. I've gathered together an (supposedly) OTG "compatible" cable (the Nokia CA-101 for Nokia 6600 Slide/N900/etc), an extra-beefy powered hub, and female-to-female USB-A adapter. I have yet to dive into the kernel to load any special drivers, try mounting drives, etc. I'm still unsure of the "OTG" cable and may still need to manually ground that fifth pin to kick it off. Though, as far as the cable is concerned, that is the only thing that makes it OTG on one end.
Host Mode Background Info: OTG Wiki
Here's a modoco thread that includes most of the relevant links I've seen.
Ideally, I'd like to find a microUSB to USB-B OTG cable that connects directly from my phone to the powered hub, but I couldn't find any. Let me know if anyone knows where we could find these.

It seems like we could create an entire new category of toys to attach to our devices if the micro USB port could be figured out. To me that's ultra exciting!
Let's go a few steps further, Being able to physically attach a printer or hdmi (Yes, I know about AllShare) to the tv could require a simple adapter that plugs into the micro USB port on the handset. We could also have a nice flash that has brackets that mount to the handset for support to get better pics in low lighting (instead of just saying "oh, I've got night mode", bugger that).
The capability to do this has to be written at the kernel level and then we need hardware manufactures willing to make the products. Therein lies the problem, how do we get that to work?

My neighbor is an electronics engineer and I'm a machinist, my friend is a tool and die maker.
My neighbor has an idea to make a device for surface mount soldering using an inert liquid with a boiling point equal to the soldering temp. This would be a cheap alternative to infrared soldering.
Other than that I might be able to come up with a housing.
I wouldn't want to commit myself untill the software works and we've tested the soldering machine.

HULU HDMI .apk solution (I think I have it)

Anyone near an HDMI cable and have a HULU Plus subscription that wants to test?
I think I managed to find the setting in the strings.csv fie that disables HDMI output from the .apk. I've re-signed the package, but I can't test it to see if it works. The file is found in the assets/ui folder:
Code:
Line 130: strings_ui.xml|ui_hdmi_output_disabled HDMI Output Disabled 1
Changed to 0. Please test and report back.

Hulu plus is giving a free month from geiko... saw it on Xbox.... so I guess I could try it for ya but I'm stock non-root (if that matters... sorry I have bad luck with phones don't want to risk it for insurance sake)... just let me know

Crap, I dont have a laptop with me to keep testing and I'm stuck in a hotel and I have to use the old version of hulu.

Tried this on my transformer tf300t tab. Installs fine but doesn't fix the HDMI output block.

yeah sorry to abandon the thread. i had to go back to the drawing board. the data file i found seems more like a tick-count than actual config info. i got side-tracked once i found this other app, that disables the display, but HULU still detects the HDMI.
what's needed here is to fool the APK into thinking the external display is the primary display, or to elminate the hardware reporting that HDMI has been enabled. once you remove HDMI, the video plays as normal. when you connect HDMI, you get a warning message and the video stops buffering.
based on HULU's earlier APKs, i know that at one point, you could get the warning message, but that the video would still display. they somehow fixed that, which is why it doesn't work. my conclusion is that once the hardware reports that HDMI has been enabled (new device found?), that HULU sends a command to stop receiving video feed/buffer.
if the APK were truly disabling the HDMI output, wouldn't the screen on the device work and you would see nothing on the HDMI device (TV)? somebody has done some band-aid type of programming to counter the issue, which should be easily adverted.
i need someone with more knowledge than me, to figure out how to make calls to the hardware layer, to detect external devices, in the manner described above. if there's some sort of permission that can be changed, or channel that can be closed, HULU can update its APK all it wants.

hangon wait, hulu blocks the use of hdmi?
iv never had hulu.

Audio playback via USB DAC (CM10.2)

Hi,
Has anyone else tried USB DACs on their Nook HD+? I've successfully attached my O2 DAC using apps to enable OTG mode and ignore USB device power requirements.
In MX Player (HW decoding enabled) I get smooth audio playback however in Poweramp the audio slows and stutters. Is this because Poweramp is using software decoding and the load is too high? I don't have this issue when using the same setup on my SGS3. I'd like to use a dedicated audio player for convenience, if possible.
Running CM10.2-0908 Nightly (EMMC) with TabletUI and v6supercharger mods and trim-enabled kernel. Also tested without on stock CM with same result.

I'm trying to do something similar, I have an IPEVO VoIP conference speakerphone thing (Model CDCA-01IP) that works over USB and has great sound when used with a computer. I'm powering it with one of those USB cables with a second plug for added power and one of those batteries for charging USB devices and connecting it to an S3 with CM10.2 with the OTG cable. The idea was to be able to do conference calls on site with better audio quality and have a rigged up speaker for the shop.
Anyway, Apollo delivers unusable stuttering sound with lag for volume changes. Trying MX Player for hardware acceleration also produced unusable sound and a similar story for speakerphone function.
A coworker with a stock S3 did not have these issues, so it appears to be a weakness of CM.

Excellent, I'm glad I'm not the first person to try this!!
I'm thinking of a new DAP, and looking at the iBaso DX50 or Fiio X3, I see both of these can act as USB-DACs.
I use my Nook HD+ as semi-portable movie screen and think the sound could do with a bump in quality to match the visuals. Any update from OP or other posters on success getting this to work?
Cheers!

More info please

If I unplug the HDMI cable from the pi and connect it to my laptop, the sound works perfectly. So does the sound on my Apple TV and Playstation. Makes me think the problem is the pi and not the TV.
The video plays great. Just no sound. Not even music plays. The config file updates aren't working either.
BUT! What's weird is that I got it working for about an hour over the weekend, but then needed to do a clean install of xbian and it never worked again. So I know the TV and pi are not faulty.
Any ideas?

Hey Dude,
can you upload your config.txt file pls.
So I can take a look on it. In my acse the problme is the TV when I plug the pi in an other Device (Video Projector) then it plays the Sound.
Did you trie'd RASPBMC?

Now I finally tried a BD DVD Player over HDMI and now I know the Problem is definitely the TV it plays no Sound.

I use a 47" 3D LG TV, had the same problem. I install a radio station who add some plug in and now it's working. Take 10 min of your time to try...

You could always try something like this and connect it to a sound bar or like device.

Update to the very latest Raspian and type this...
Code:
sudo nano /boot/config.txt
Scroll down to where you see "#hdmi_drive=2" and then delete the "#"
Then press Ctrl-o and then Ctrl-x to save and exit.
Reboot the system, and you may have sound!
I had the same problem earlier in the year, and I had to jump through a few hoops to get sound working properly, I did a fresh intall this week, and I only needed to use the above to get sound via HDMI.
