[minnow for whale]USB Video Out Dev&Dig (Status:success)

[marsrogers]

We all remember at the MIX10 Joe Belfiore projects his phone onto the big screen. Even on the recent XBOX show he did that again.

http://www.youtube.com/watch?v=uCDXaJh4bwE

this kind of video out is through micro-usb, normal type one. You can find Joe is using a Lumia 800 in his hand in the XBOX video.

I asked him through twitter and received an answer of "Special Software build".
I did some research and dig into the register keys. Found something.

This is a special driver that only shared inside the MS and normally won't be out anytime soon.

Big Step Forward, since the DFT Rom released, the exe can be run in WP7.
One thing I need now is if someone can build an app for me, which calls the changeusbprofile.exe under /windows

Things here is I'm using the Opera mini launcher to call it, but the path is under /application, not under /Windows, and the result is my computer can not detect the phone when the phone reboots. I think this may relates to the path I call.

I'm not a typical tech-man, so I need help here. Thanks!

----Update on 2012.Feb 9 23:00 China Shanghai Time----
Today I really thank @GoodDayToDie and @ultrashot for helping so many.

@ultrashot sent me a xap app that does the job, calling the changusbprofile.exe in Windows folder. Although result is the same with yesterday, but now I am more sure that we are one more step closer to our destination. I'll wait my new micro usb cables to arrive and then I'll make a second try. Thank you again!!! Can't reach here without you kind people~~~

----Update on 2012.Feb 10 19:22 China Shanghai Time----
I removed the attachments because the project is now on special stage. I will put them back after the feature works, or after I can't make it work. Either way, I will put them back~~~Don't worry.

----Update on 2012.Feb 12 15:22 China Shanghai Time----
Complete failure....
New cable arrived and still my computer can't recognize the phone in usb video out mode...I changed a computer and till the same...

Will think about next steps...if I can't make figure it out next week, I shall put everything at present stage onto here.

----Update on 2012.Feb 14 10:22 China Shanghai Time----
Think it over, and think there is still a hill in front of us. The changeusbprofile.exe seems just to be a toggle, like a shortcut. But the real port of usb video out hasn't been enabled. On my samsung focus, I checked the *#7284# in Diagnosis Mode before and after I ran the changeusbprofile. The thing changes from Zun to Tethering, while it's not the real tethering mode. I think the changeusbprofile is just doing a job like changing usb mode from zune to tethering or to Diag mode. So that's to say, we haven't really seen the iceberg yet. I'll keep finding and hoping that anyone can get any help on this. This may requires me to dig some post in Windows Mobile age, since some parts between the two system are same.

And I contacted the kind secret person, and get the news that the usb cable doesn't really matters. Any short cables should serve the job. So our attention should move back onto the phone again.

----Update on 2012.Feb 15 15:13 China Shanghai Time----
I figured it out~The changeusbprofile changes the value in Registry Local_Machine/Drivers/USB/FunctionDrivers, DefaultClientDriver=CompositeFn to UFN_VIDSTREAM_CLASS. Every value change here points to a folder in FunctionDrivers.
in Samsung Focus, it is like below:
/CompositeFn;
/CompositeFn_QCOM;
/CompositeFn_SAMSUNG;(This is the one when we choose Diag Mode in Diagnosis App *#7284#)
/MtpClientDrvUsb;
/Samsung_USBSER_Modemlink;
/Serial_Class;
/Serial_Class_Diag_Qcom;
/Serial_Class_Nmea_Qcom;
/Serial_Class_Trace_Qcom;
/USBSER_Class;
/USBSER_Modemlink_Qcom;

There is no UFN_VIDSTREAM_CLASS folder here, so that explains why the changeusbprofile works well while it is no use at all...
Next step, I will try looking for the Setting in Asus E600, if I can find someone who has this device. Maybe Samsung Taylor will do the same.
If you can help, don't hesitate~~

----Update on 2012.Mar 3 15:13 China Shanghai Time----

Updated some info
I looked into the Key name, UFN_VIDSTREAM_CLASS, which is very unique way to name.

This belongs to a USB function Driver, and the only thing I saw similar is a UFN_PRINTER_CLASS, which is in Wince 6.0
http://msdn.microsoft.com/en-us/library/ee483856(v=winembedded.60).aspx
And you may check this
http://msdn.microsoft.com/en-us/library/ee485691(v=winembedded.60).aspx

So I'm still waiting for somebody who can offer any help on this. I talked with Mr. Yang Zhongke, who invented RecX prototype, fiinix optimized that, but not the inventor.
His way is not quite efficient and seems can't go further. But he will do some work for this in a foreseeable future.

Any one has a Asus E600, plz contact me, will keep your name secret.
Thanks!~

Project suspended, cuz according to a source, WP8 will have Remote desktop support.

"The ability to take screenshots (via Remote Desktop, no less) will be a feature of Windows Phone 8. I don't see anything changing before that."

"Only that you will be able to remote desktop into the Phone, which should allow you to create videos and/or screenshots from a PC."

The source is quite trustful, and I have no reason to doubt that.
So just be patient, and it will come. No need for this project to keep going.
At last, use my words in the email I talked with the source.

Me:Really puzzled why MS doesn't release such a cool and convenient feature. Haven't they realized that when people use this feature, they are promoting WP7 for free...(Actually I've promoted in this way for Android as a "side effect" in the company I work in for three months and as a result more than 20 Samsung Galaxy SII were added during this period. Google and Samsung should thank me...)

---Update on 2012.August 17 14:21 China Shanghai Time---

A very kind man has sent me the 7003 LG Panther ROM, which has the necessary file, and we successfully got them out. But I just lost my sell phone, so it may take some time to buy a new WP7 Samsung focus. Maybe next week. Very close to the final line. God bless us. Cheers.

Good luck!~

--Update on 2012.August 20 22:37 China Shanghai Time--

I tried to make it work while it still failed. The computer recognised my cellphone as WM7VIDSTREAM while the PC side app still does n't work.
I think this could be related to that the PC side app is for mango and the cellphone side is grabbed from 7003. I uploaded the VSD folder which contains what I think are the everything we need for now.
If anyone wants to build an rom, now it's the time.

--Update on 2012.August 23 17:42 China Shanghai Time--

One friend, who you will know someday later, gave me a home-make cab which includes the pkg file from Microsoft. Right now it is not for public for now. But it is successful.
Although I started this project, but as it always be, not a technique project but a sociology one. So there are many things and many people's benefit to consider. So just wait for some time, it is there when it is there.
For technique part, the pkg file includes as same as the VSD.rar in the attachment.

Cheers

Well, I can tell you a little about the thing you found (good investigation, by the way!)

First off, that's a module - it's kind of like a file (and shows up in the filesystem) but is baked into the ROM and can't be opened, much less modified, like a normal file.

There are tools that are supposed to be able to re-assemble modules, such as recmod. I haven't been able to get them to work, but maybe I'm just doing it wrong. In theory, it should be possible to create a "normal" DLL out of the components of a module.

The next trick is getting that rebuilt DLL onto the phone. This can be done pretty easily on Samsung, and is possible on interop-unlocked HTC, but on LG/Toshiba/Fujitsu/Dell/Nokia we don't currently have a way.

After that, you'll need to "install" the driver. Now, there's a registry entry for doing this. The problem is, I only know that the entry is required - I don't know if it's sufficient, or if there's also a database or something that must be updated. In any case, any phone where we can put a file into the Windows folder, we can also do registry editing.

Then there's the thing of actually getting the UI for this feature (the Settings "app" to control it). It's vaguely possible that the retail ROMs include it, but this is doubtful, so you'll probably need to pull it out of that old ROM. It's probably an EXE, so it's unlokely you can make a XAP for it - instead, you'll need to install it into the phone directly, including putting in the registry entried to launch it (this is a guess, I've never tried).

It's worth noting here that it's probably *WAY* easier to just pull that feature out of your old ROM and bake it into a custom ROM. This should be pretty straightforward, however, then it's only useful on custom ROMs, which in turn are only possible on HTC phones (right now).

Thanks for your reply. I did something with the recmod, but the dll it packed is only 1kb, apparently it's not useful. I guess it is because there is no imageinfo.bin inside the dll folder. I used some tools recommended by Da_G who started to try modding WP7 on the first day. Like nbsplit.exe to creat a IMGFS.bin, and use xidump to dump it. Just like what they have done before, I got the dll folders as same as I got at the beginning.

You may be right for the part that it's rather easier to build a new rom. There are tools to repack the whole IMGFS from files while I didn't find any good ways to pack a specific folder.

May ask more people all over the world (thx to the internet) cuz I just moved from android. In android, I use cygwin to pack the Odin Tar files, but it's totally different of course.

Anyway, doing this research is just for fun~ All is because MS is moving too slow...not to mention the NFC function I already have for a year on my Nexus S~~

Thank U again!~

 

[pLUSpISTOL]

This would be awesome good luck

 

[-WP7User-]

Really a good find! Found that reg entry some time ago but I didn't care about it...Now that you bring up that thing again I also think that this could be very useful (even if you want it just for fun and not for business purposes). But note that the DLL file doesn't have to be in the /windows folder. It could be somewhere different, too.

 

[GoodDayToDie]

@-WP7User-: That's an interesting idea, and might enable this to work on LG phones (where we have registry but not filesystem control). The registry value that speicies the path to the driver binary only ever gives the file name (example:
[HKLM\Drivers\Builtin\HTCFileUtility]
Dll="HTCFileUtility.dll")
However, it might work to specify a full path instead of just a relative one (relative to the \Windows folder, one must assume, since that's where the files in question are located).

However, there's still the issue of actually getting the phone to load the driver correctly. Just adding or editing the registry value for Drivers\Builtin didn't work for me - it did something (the driver stopped working when I chancged the value for an existing driver) - I wasn't able to make a user-added DLL work (even a different version of an official driver).

 

[-WP7User-]

any news on this?

 

[drkfngthdragnlrd]

The old Recmod doesn't work on WP7 files. I believe there is a patched version for WP7 floating around XDA somewhere. Have to check my files, could of swore I downloaded it once.

EDIT: Here you go.

 

[marsrogers]

I have get the source code for creating the dcTNONE_ANALOGTV.dll, they are .c file and .def file.
My Problem is I don't know how to build them.
And I have got the changeusbmode.exe and the xml file with it. Figuring an idea to put them in.

Download the FixRecMod.exe above I posted. Drag the dctNONE_analogtv.dll folder with the "s000 s001 s002 s003 s004" files in it over the exe. Now you'll find the actual DLL file inside the folder. Any problems, just upload the folder & I'll do it for you.

I have made the dll successfully. But when I put the dll into the /Windows folder in my Samsung Focus, nothing happened even after a reboot.

And another interesting thing is in WP7 Root Tools, when exploring the /Windows folder, all single file has a "ROM Module" or "ROM File" written blew, but the files I moved in has nothing written under it.

I tried to check the usb mode in diagnosis *#7248#, still there are three options to choose, nothing new.

I personally don't see the future of this project for now.

However, You have done a lot to help, it's very kind of you, thank you so much!

It wouldn't have ROM FILE/MODULE under it as it wasn't cooked in. You probably need some registry for it to work. Also, try opening the DLL in PEexplorer & checking to see it it has a cert attached.

Example of a DLL/EXE with a cert;

 

[-WP7User-]

Gonna cook it into my rom and try it out...Do you have an idea which reg entry it could need?
I think of something for the settings page. Because if you haven't got a settings page for it, how can you activate it?
And maybe another entry which points it to the DLL file...?

Next weekend I may upload the dcTNONE_ANALOGTV.dll folder which I found in the leaked ROM for HTC Surround even before the WP7 was officially to public, the source code which is .c and .def for it, which is to remove some limits for QSD8250 CPU, and the changeusbprofile.exe and changeusbprofile.xml from Asus E600 (the only dev phone has the display mirror feather in 7720 for now)someone Mr X, who I am very grateful to gave me.

I ain't major in this level of computing techs, so I think in order to make the project alive, it's better to share what I have to those who has the ability to do it. Let them holding in my hand is a great waste at present stage.
The QSD8250 is a very old cpu, so there should be no problem with NDA.

P.S
There should be a manual installed usb driver on PC and a client application on PC but I don't have them right now. If you have friends or friend's friend who is a dev, holding a e600 dev phone, try ask them to share something, appreciated.

I've uploaded all my files so you can make the check yourself.
After all I'm major in management not IT techniques so I don't want to pull the path down.

Thank You for the help you offered!~~~

 

[-WP7User-]

Thanks for uploading your files. But it seems like I can't find the reg key...
There isn't a single reg entry which points to the uploaded .dll. At least not in the official Mango Update for the HD7.
But if you post the whole entry, I could try to cook the .dll into my rom and see what happens.

has this registry something to do With that ? :
Local Machine\Drivers\Display\TV\
PanelDLL=string:"dcTNONE_ANALOGTV.dll"

Just like @tessut posted. It's it. And I think you'd better try to build the dcTNONE_ANALOGTV.dll yourself from the source, it should be more reliable than using fixedRecmod. I can't do that cuz there seems to need many head files that do not exist in computer even I have vs2010...

Sent from my SGH-i937 using XDA Windows Phone 7 App

 

[-WP7User-]

Okay, if someone wants to try that, too: The exact reg key (just copy and paste) is
[HKEY_LOCAL_MACHINE\Drivers\Display\TV]
"PanelDLL"=string:"dcTNONE_ANALOGTV.dll"
Didn't flash the rom on my device yet, but that's soon going to happen
The dctNONE_analogtv.dll is in the windows folder, the changeusbprofile.exe and .xml are in there, too. I hope it works!

EDIT: Didn't work at all...The ChangeUSBProfile.exe didn't get installed (although I'm 100% sure that it is there and of course in the right folder). Wasn't there a license xml around or something? Because normally a Windows Phone 7 App needs a license file to get installed when starting the phone for the first time. Don't know if this applies to .exe files though.
Has someone got an idea?

Thanks for the work! Is it possible if we extract the official .cab update file to get a licence and patch it to the exe?
I used a PE Explorer to open the changusbprofile.exe and found a license called"Windows Mobile TCB signing cert" in it.
Another thing is I used a way to open .exe in IE (use IE in WP7 to open this thread and download the usbvideoout.zip and you can have the chance to open changeusbprofile.exe directly) but it failed in Mango. Maybe we should try this in 7004 because this is really an old file. Or we should find a .cab file that contains a exe file in it and this .cab must be announced after mango update.
