Hi all. Bear with me as I'm new to the dev community for the Android OS.
Basically the story so far is I've got a Droid Eris. I saw that there is a cable available called the Act100 Video Cable by HTC. This cable plugs into the mini usb port of the phone and outputs a composite video and left and right audio signal, yellow red white cables. I have a TV in my car that accepts composite input.
Through some research I've found that the Eris does not support this video out function. A supported phone for example is listed as the HTC Touch Pro 2 on sites where you can buy the cable. I've read in forums where people have mailed HTC about eris video out compatibility and HTC said that it isn't in the software by default but to try and search for an app that enables it. Therefore, the hardware supports it but it simply isn't an option in the software. So I want to make an app that simply enables the feature on the Droid Eris.
This is where my questions start. I've had only limited C++ programming experience so I'm prepared for any learning curve. How difficult do you think it would be to make an app like this? I know of some begginer guides but beyond that where should I begin?
How do you find out that the hardware does, in fact, support this? I would think if this were possible it would have been made by now, but I'd love to be wrong.
I'm not 100% sure the hardware supports it. I just made a guess because in the post I read HTC support tells the guy to look for an app that enables it becuase it isn't in the software by default. It sounds like it might just have to be coded in. At leat I'm really hoping it can be.
Sounds fishy to me. Every portable device I've ever used with a TV out function required a hardware decoder specifically for a TV. This can be done in software I'm sure but the other issue I find is pushing it out over the USB jack. Analog video source pushed out through a USB chipset doesn't sound like it can be done. I'm not all that knowledgeable about the Eris' hardware specifics so don't quote me.
As far as a pure software app that will do it, that raises red flags as well. As far as I know apps on a stock ROM run in a Dalvik VM I believe. They're separated from the system itself, and it's the system that controls the hardware. It might be able to be done but I doubt it.
The Touch Pro 2 might have the ability to do it maybe through hardware, but as far as I know the Eris doesn't have any of that.
I'll let somebody with more hardware knowledge come in.
Thanks for the ideas so far. Well since the touch pro 2 can output video over usb it's obviously possible to push the signal over any other USB. It would just be a matter of, as you said, the Eris having the hardware. I guess I was under the impression that the hardwares were very similar. I'm really trying to investigate this as much as possible and no one even answered me on other forums. Please keep this thread alive!
I don't know for sure if this can work, but here are my thoughts. PDANet sends data over the USB port to enable wired tethering, so an app can send data over the USB port.
So since we know we can send/receive data over the USB port, we must address the issue of video output. I don't know if this will be easy because of the way USB->Composite converters probably work (read output of the USB pins into each of the Red, White, Yellow pins). What would potentially make this difficult would be that with Dalvik I don't know if we can control what pins we are outputting our data to.
If someone wants to post more information on how the video cable works it would be easier to determine if it is possible.
Check this out. The Droid Incredible does it over microUSB. I wonder if all we need is the right cable.

I would love to see you make an app for this if its possible. Is there an option on stock incredible for this or is it an app?
Nindoja: Yea I agree pin control is probably going to be important for something like this. I would prefer not to, but would rooting allow us to get around the Dalvik restriction you mentioned if it ends up being a problem?
ihtfp69 and conap: I did see that the incredible does the tv out over usb. I'm not sure wether it is an option or an app though... I also read that the incredible's files were leaked, including one called tvout.apk. I think I read that just trying to install it on the eris doesn't work but I'm really not sure. In the least having that file to work with might be a great start.
I haven't been able to find that file yet unfortunately. How similar are the Incredible and Eris hardware? If they are similar it could be good news for a software solution.
Thanks for the replys so far! Any other thoughts?
Has there been any development on this?
nope, none public at least
Bumpity bump bump. this needs to happen!

Did you read the thread at all? The problem isn't only software.... the apps the incredible (and other phones that have video out) use make extensive use of dedicated hardware to output the video stream.
We don't have that on the eris, so that would be really hard, and very slow, to emulate in software. That's assuming it could even be done over our USB port.
shouldnt be that hard, the same thing has been done for PSP...although its USB video out to PC.
its probably a step in the correct direction.
goto youtube.com and search for 'remotejoylite' one word, should be second video down, shows it in action via usb cable.

Am I missing something, but haven;t at least three comments made before this one confirmed, several phones have video out, via USB. I think the assuming iot is possible part is over. The real question that no one has answered is if the Eris has the hardware to support this option. I don't have an answer, but wanted to point out that the possibility of video over USB has been answered.
If you look on Google you can find the tvout.apk and tvout.odex from the Incredible dump. Might be able to do something with it.

I think with the right cable and the right software we can get this to work.
We might also need system/lib/libTVOUT.so
From what I can tell, on a stock ROM the TV out functionality is provided by system/app/TVOUT.apk and a system/lib/libTVOUT.so
here is a link to a forum about the MyTouch and the tvout.apk and cable:

Question.
Has anyone seen this work?
How do you make it work?
Do you select it from the launcher?
Is it in settings?
Because we would have to find a work around if it is.
Or just add it to the menu.
Ha.

I read on another site that Samsung/Sprint removed the TV OUT function from the EPIC 4G. I am specifically referring to the 3.5mm to RCA cable that would allow you to view whatever was on your phone on your TV.
I know that you can use the DLNA function to stream to your DLNA TV/PS3/XBOX or buy the USB to HDMI to do this but I already bought the NOKIA cables that would allow me to use the 3.5mm jack to do the same thing (though not HD) like you can on the Captivate and Vibrant.
Thanks to anyone who can take the time to confirm/deny this rumor. I sure hope this is BS coming from an EPIC hater.
BTW: I ordered my phones (1 for me and 1 for my wife) through Sprint Telesales and now have to wait for them to ship otherwise I would check this myself

There is no TV out with the Epic. It's been confirmed all over the internet. We can only hope it will be put back in once the Epic gets TW 3.0 + Froyo.

This was a major feature that I was looking forward to using. It would have been great to use at hotels and my mom's where she is one step above rabbit ears
Would either of you know if the USB to HDMI cable would allow us to use the TV OUT function or is it DLNA only?
See also this thread. It started out focused on the TV out issue and related matters before it got hijacked.
Thanks Boomer. I'll check it out.

I think this is the only option we have. Although, can a stock i9000 ROM that has the TV out option be used on the Epic?
Has anyone figured out if tv-out is disabled by software or just not possible? and if it is a software lock out, has anyone figured out how to re-enable this feature?
thank you in advance guys
I too would love to know if this would be possible! thanks!

I assume you are joking since the Evo uses microHDMI for TV out. That's a port that does not exist on the Epic.

This guy claims TV-OUT on Epic's hardware is disabled. Dunno how reliable of a source he is, but I guess we'll be closer to knowing for sure once we get froyo 2.2 on our Epics.

Okay, if the Verizon Fascinate has Tv-out his argument will be invalid. I guess we'll just have to wait for that or froyo to learn more unless someone else has anything to offer.
I've also heard that the epic has a different 3.5mm controller, so that may be one clue

i know my new sharp aquos quattron or whatever it is has a similar issue. i can play files via usb. i can send the tv pics/music.. but no video. ive decided to just have it link up with my ps3 instead as it can handle video streaming.
Verizon's Fascinate does not currently support TV out either.
Just for kicks.. has anyone tried hooking it up and see if the option appears?? i dont have a cable to test with
I got one on ebay and tried so without another compatible device, I'm not sure if I just got a bad cable or not. I even tried using white and red as the video just in case cable was funky, but didn't work. I swear I read somewhere that the option would appear after plugged in, but no tv out option appeared in sound/ display settings.

Edit: read in a bunch of different places today that an update killed TV-out... People had the option and then it was gone after update. This gives me hope that some of the pros here can give it back
There is a cable that is made by cygnet, that has the epic usb to hdmi, works with epic. Retails for $24.99, you can find them at Fry's Electronics.

Sorry buddy, definately no Bluetooth built in. The chip was at first mistaken as the same from the color but actually it's a chip derrived from the same as the Nook but it's had FM and Bluetooth removed to save money :/ Bummer.
The only way would be to develop a USB host mode like the Samsun galaxy and with that you have to be careful not to fry chips. mmm... chippies

Hint: USB Host mode
The NST is in fact able to do this, it even loads the USB in OTG mode, but our kernel doesn't have all the bells and whistles required for it to work.
There are patches for 2.6.29 afaik (CM), so you go recruit some kernel hackers and you'll have BT adapter support in no time

Any progress?? I want to Bluetooth tether to cell via USB Bluetooth.
i think it is not possible yet ^_^
Edit:
So it seems the consensus is that this will probably not have HDMI out (through a cable)
But obviously it can stream it's video over wifi (or bluetooth?)
So I want to know if anyone knows of a cheap solution. Like using Apple TV or Nexus Q (But MUCH cheaper)
Also, would wifi streaming, say Netflix, AND wifi streaming to the TV destroy the streaming quality of Netflix?
Let's figure this out!
So I don't think this has an HDMI port (Maybe micro to Hdmi?)
But does anyone know cheap wifi HDMI out solutions? Like Apple TV, but CHEAP.
This is one thing worrying me about this tablet. ($300 for the Q is horrible)

That's may not the same model that's shipping though. We may not get this feature on the consumer version.
Check out around the 9:00 mark of the keynote. Whether it makes it to production is to be seen but obviously they are putting video out.. also on the Google Play Store under tech specs they don't mention the Galaxy Nexus has MHL.. but it does
Once MHL is confirmed I'll probably have to order up another Nexus 7 to use as a media server. I'd just mount it to my stereo cabinet and run it through my receiver. Too bad the HP Touchpad never had MHL support, it'd give new life to my soon to be retired device.
The Q would upset and confuse anyone who didn't already know what it was if they saw it in my living room. I'm not very impressed with the amplifier on it either.
Yeah If they confirm MHL I'm in. It does look like they had special versons with hdmi though. I'd be saddened to learn that I can't hook it to a tv. It was a deffinate buy for me before but without hdmi I'm out.

So prbly no HDMI, and if it has MHL we won't know until it comes out. So we may as well prepare for it not having MHL.
If it has it, well then this thread could be useful for a different device.
If it doesn't, then this thread is important
Either way. This will help people feel better about their purchase if they know there is an HDMI alternative.
I agree. I hope there is MHL but if there is another HDMI alternative I'm all ears.

Actually I re-watched the videos, and the only cord they are using is plugged into the Micro USB SO:
A) There is MHL (at least on the display, but why not all of them?)
B) They were just keeping it charged while they streamed the video through the Nexus Q (more likely)
If only we could ask someone that just got one free at the event!
Edit: Just tweeted to Aaron Baker of PhoneDog.com who received a free Nexus 7 at the I/O to let us know in his full review if it has MHL/HDMI and Tablet support. We will see what happens.
