[HDMI] Investigating HDMI out/mirroring - Streak 5 Android Development

HDMI out has been a highly requested feature, but one that has barely ever worked in the liftime of the S5.
What we currently know:
Stock gallery can output video/audio over hdmi
Stock music can output audio over hdmi
A multimedia dock is required
Both apps can output while displaying something seperate on the device screen[!]
The techincal parts:
Stock gallery depends on libcom_cooliris_hdmi.so
Stock music depends on libcom_oem_hdmi.so
Stock in this definition refers to the stock included gallery/music on stock streak roms, the HDMI out is NOT included in standard 2.2/2.3 AOSP(?)
Stock gallery is com.cooliris.media (Gallery3d.apk) which is available as source though AOSP(?) and the included one is different from the (previously available) one on the android market.
Stock music is com.android.music (Music.apk) is just the AOSP music player with hdmi out added.
Next week or so I am going to attempt to isolate the lines in music.apk that allow it to output audio and hopefully this will at least allow us to consistantly output audio over hdmi.
Also, this is entirely different from the HDMI out on the S7/S10 as they simply use the built in functionality of the Tegra2, which can natively output hdmi. The major difference is that they seem to only be able to mirror video while the screen is on while the S5 can independently ouput.
The S5 is potentially more powerful then the S7/S10 at outputting over hdmi (under the massive assumption that it can output more then just decoded audio video)
IF HDMI out only works on the S5 by taking decoded streams sent to the mediaserver it will NEVER be able to be used for HDMI for anything but what it can already do.
IF I am able to isolate the hdmi out I will likely need the assistance of a app dev, as I dont have any experience actually building apps. Reversing apps and making apps are independent of eachother.

This might make your app obsolete when it gets released because it will work for all android phones, however only if the price comes down a bit cause seems a bit steep for what they are predicting.

That requires external hardware, if it requires someone to port it to a specific device I seriously doubt the s5 would ever get it.
Just as much I have absolutely no reason to buy another block to get hdmi out, I already have a multimedia dock. It also works over wifi and I dont expect I'd want it for that reason even if someone gave me one for free

Thats true Manii.......and it would be great to have all vid and audio output in hdmi

I believe 90% of the relevent code is isolated into the ones marked -HDMI specific functions/added, there's many other changes, but most of them are changing of static constants and things possibly to make music.apk itself work better on the display.
Beyond the hdmi specific code the majority of it is shuffling code into sub-files/classes.
The HDMI enabling code is only a couple hundred lines, while the entirety of the modifications are <1000 lines of code.
The version compared: stock SD244 music.apk vs Nexus1's 2.3.3/GRI40 music.apk as SD 244 is based on GRI40.
The SD244 one is based on the stock dell one, it may in fact be the stock dell one from 2.2 or something, regardless it's not relevent.
It might be possible to make a hdmi audio output enabling app with just this code, the music and gallery apks use different libs when it comes to hdmi, the music one may only work with audio out.
The limitation of the music player not having any controls during hdmi out is likely a limitation of the player itself and not the outputting.
The stock one also lists specific codecs available vs the n1's which lists all audio types. It might be a limitation that the lib can only output streams it can hw accelerate, which means it's potentially a massive limitation of the hdmi out.
If this is the case it may only be viable to output music and not generic sound/video.

libcom_oem_hdmi.so
Well, afaik Java can call external libs (got no Java exp, sorry)
Anyway, quick peek at libcom_oem_hdmi.so:
All operations seems to go via
/dev/graphics/fb1, then MediaServer is notified.
Most probably simpler way would be to write an app that would enable and disable hdmi standalone. And this should work as hdmi is done in external chip.
Both funcs (enable and disable hdmi) take NO parameter, so it should be easy to reimplement.
Got no personal interest, but following code might give some ideas:

It's calling it though JNI (or whatever equiv it is in dalvik)
I didnt bother decompiling the native libs since I'm more interested in reading smali code then arm assembly.
Regardless it still sounds pretty simple overall, how unfortunate noone looked at this as it's been requested multiple times for a hdmi helper app

I think Meltus would help with this case.

If I could use hdmi with custom roms I would buy the dock right away.
Keep up the good work

I'm not a dock reseller , and don't have one to check, but i think it'll work.
Lubo seems to have one.

I have done extensive searching on the net on this one. Apparently, streak's GPU is not capable of HDMI mirroring. i.e. it's a hardware restriction.
Although I m not sure how reliable this information is.

Decoding/encoding in android likely never involves the GPU as that's pretty expensive, just as much the GPU in it likely isnt powerful enough anyway.
All mobile SoCs likely have a dedicated decoder ASIC to handle all the common codecs.
The question is what does the HDMI chip accept? Is it raw RGB data or simply an encoded stream?
There's a real possibility it's only the latter as currently the only thing you can output are videos/audio (which are just that, encoded streams)
If that is the case you would need to encode the screen's contents before feeding it to the HDMI chip and that may be not be an easy task (though definitely not impossible, it's not that different from what the video capture part of the camera app does, it can encode and mux at 720p in realtime/near realtime)

The Dell Axim 51v, which was released in 2005, had an 8MB 3D graphics chip and native VGA out with mirroring. It was perfect for giving presentations; like having a pocket sized laptop, which plugged directly into a data projector. To my mind, it is ridiculous that a device made six years later can't do the same. I still have my Axim 51v, now with a WinMo 6.1 ROM.

yes it can be done. although it might require too many resources and result in a lag.

TheManii, would you check this:
http://forum.xda-developers.com/showpost.php?p=26165133&postcount=3991
What am interested in: will third party app output anything to hdmi with forcefully enabled hdmi?
It's clear that player should stream to /dev/graphics/fb1 and system player libraries use it. Soft-decoded videos are not the case.
Also - will force mirroring work with the command like this:
while [ 1 == 1 ]; do cp /dev/graphics/fb0 /dev/graphics/fb1; usleep 10000; done;

Someone already got it to it before I did, I havnt been on much recently.
But try feeding into fb1 various mpeg2 streams, possibly WVGA ones of the right characteristics.
Hardware encoder chips are a lot less flexable then software en/decoders so it might be complaining about that.

Raphael WM6.1 ROMs Page Pool / Page Pool Changer

Dear all [especially the developers],
Is there a practical way of changing the above mentioned ROM's page pool?
Is there a tool?
I tried Latest Page Pool Changer release [V.2.21] but it doesn't behave as it should.
With JCEspi2005's help I realized it doesn't report or write the right or, at least, the reported and visible values...
How can we sort this out?
Can someone point me in the right direction?
Hang Tua, given the fact I am solely using your ROMs would you be so kind you would help me?

Dear all,
INTRODUCTION
With JCEspi2005 precious help and guidance and Swiftblade precious information, we both came to the conclusion that Raphael page pool change method can now be unveiled.
CONSIDERATIONS
JCEspi2005 changed a ROM's page pool to 24 and I tested it.
Result: Ok.
I changed 2 ROM's page pool and tested it.
Result: Ok.
TOOLS
A Hex editor like:
XVI32 V.2.31 ¤ Link
HexEdit V.1.03 ¤ Link
PROCEDURE [Information source: Link]
Address: 70F0
Values:
[00MB Pagepool] |00 15 A0 03 | 02 15 A0 13 | 00 10 83 E5 | DA C2 FF EB|
[12MB Pagepool] |03 15 A0 03 | 02 15 A0 13 | 00 10 83 E5 | DA C2 FF EB|
[16MB Pagepool] |10 16 A0 03 | 02 15 A0 13 | 00 10 83 E5 | DA C2 FF EB|
[18MB Pagepool] |12 16 A0 03 | 02 15 A0 13 | 00 10 83 E5 | DA C2 FF EB|
[24MB Pagepool] |18 16 A0 03 | 02 15 A0 13 | 00 10 83 E5 | DA C2 FF EB|
1. Open the OS.nb or the .NBH file with a Hex Editor
2. Search the for hex string pattern |03 15 A0 03 | 02 15 A0 13 | 00 10 83 E5 | DA C2 FF EB| [Two addresses should be found]
3. At the first address found, change the first two bytes "03 15" to "12 16" for 18MB pagepool
4. Repeat Step Nº 3 at the 2nd address found
5. Save & Exit the Hex Editor
6. If you are using the OS.nb, start cooking your new ROM with it
7. Flash the new .NBH file to your Raphael and enjoy the 18MB True Pagepool
For other pagepool sizes, change the first byte "03" to "XX" hex value corresponding to your desired pagepool in Step Nº 3 and 4. [Remember that this is hex value, i.e. "10" = 16MB, "12" = 18MB, "18" = 24MB, etc.]
Happy Page Pool changing, happy flashing and cheers!
P.S. There were some doubts about dynamic page pool [Page Pool 0] usage but after a day of testing 0 page pooled ROMs I can almost assure the there are not stability issues.
Although several more days of testing [at least 2] are needed to ensure it doesn't affect stability, by now, I can infer that it is quite stable as well as reliable.
MEMORY
Do note that your available memory will differ according to the page pool you use.
If you feel like knowing how much memory you will have available after page pool change, maybe it's time for some linear and simple arithmetics
This post will be updated as we find out about new information or outcoming issues.
Special thanks to JCEspi2005. I hope out «partnership» goes on and on
Cheers and good luck to all.
Hi there,
I've tried pagepool changer and it appears to work just as it says on the tin!
If you look on the right hand side of the windows there is a box where you can change the pagepool size. Hit the button and you'll notice that the ROM file has been changed (Check the date stamp if you don't believe me) I've checked the ROm image with a hex editor and it has change the corrct values.
Hope this helps.

Attached is a little application to run in your PDA. DevHealth.exe generates a mem_X.txt file on your SD card root (let some time to do it). Inside this file you can view the real PagePool.
Can you test your changed ROM to see what changes do?
Cheers

That's not the question...
The question is: Does it read and change the right addresses?
No it doesn't. JCEspi2005 created a ROM with PP12 and the referred tool reads 6.
I'll try to find a tool that correctly addresses Raphael ROMs.
Cheers.
mrvanx asked me about this thread.... yes I can confirm the pagepool changer will not work, as nk.exe dynamically sets pagepool, depending on (probably) ram size. htc niki and elf/elfin are the same deal.
this is easy to fix of course with a small assembly patch

Are you planing yo make the "small" patch for us?
Following this post http://forum.xda-developers.com/showpost.php?p=2274534&postcount=1 i managed to create a modified NBH of WWE shipped ROM wirh 24Mb PagePool for someone to test it (i can't do it for now...)
The link

Would you be so kind you would inform us (if you can) of the addresses and values for Raphael ROM's pagepool?
Even if there is no tool yet, we can HEX edit the NBH and change it.
I am personally interested in pagepool 0 [dynamic].
Thank you in advance.
Cheers.
well, here is an example:

.text:80058230 94 08 9F E5 LDR R0, =aKPagePoolSize0
.text:80058234 01 0C 53 E3 CMP R3, #0x100
.text:80058238 03 15 A0 03 MOVEQ R1, #0xC00000
.text:8005823C 02 15 A0 13 MOVNE R1, #0x800000
.text:80058240 00 10 82 E5 STR R1, [R2]
.text:80058244 00 30 97 E5 LDR R3, [R7]
.text:80058248 08 00 53 E1 CMP R3, R8
.text:8005824C 01 15 A0 03 MOVEQ R1, #0x400000
.text:80058250 00 10 82 05 STREQ R1, [R2]
0x803F6350 is what the pagepool changer usually patches, this is set to 6MB by default in the nk.exe. the problem is the real pagepool will never be 6MB, this code above dynamically decides if 4, 8, or 12MB it should be. (on my raphael it went for 12MB)
the elf patch is ok, as long as the STREQ on the last line doesn't execute, if it does, then copying the elf patch is not enough. so I suggest this patch:
STR R1, [R2] -> NOP (00 00 A0 E1)
and STREQ R1, [R2] -> another NOP (00 00 A0 E1)
after this pagepool changer should work nicely, and this is easier than that patching for Elf. once you patch the nk.exe like this, it will be fine.
on top of that, an entirely cosmetic patch: you can change the R1 contents too (similar to Elf patch) so KITL log will show the right value.
P.S: my guess is it only sets it to 4MB if ULDR is loaded. so usually not of importance.

.text:80058250 00 10 82 05 STREQ R1, [R2]
0x803F6350 is what the pagepool changer usually patches, this is set to 6MB by default in the nk.exe. the problem is the real pagepool will never be 6MB, this code above dynamically decides if 4, 8, or 12MB it should be. (on my raphael it went for 12MB)
the elf patch is ok, as long as the STREQ on the last line doesn't execute, if it does, then copying the elf patch is not enough. so I suggest this patch:
STR R1, [R2] -> NOP (00 00 A0 E1)
and STREQ R1, [R2] -> another NOP (00 00 A0 E1)
after this pagepool changer should work nicely, and this is easier than that patching for Elf. once you patch the nk.exe like this, it will be fine.
on top of that, an entirely cosmetic patch: you can change the R1 contents too (similar to Elf patch) so KITL log will show the right value.
P.S: my guess is it only sets it to 4MB if ULDR is loaded. so usually not of importance.

yeah, and who pointed that out originally?
I've tried the posted procedure for finding, and changing the Pagepool - but everytime i search for the hex string, i get no returned results. Am i doing something wrong?

[USB-HOST] Contour ShuttleXpress support

I'm trying to get my Countour Shuttlexpress working with usb host ( using cm7 nightlies )
I've already posted some of this in the usb-host thread but seems there is not much devs traffic there LINK
So I've decided to open a new thread hoping for some interest and maybe info for others who want to write/port their own usb-host drivers

Eventually what I'm trying to achieve is :
Jog Wheel - Controls system/media volume
Shuttle Knob - PREV/NEXT song on PowerAmp app
Buttons - Launch Apps , Jump To Screen #n , Run Terminal Commands
That's on the basic level of things
I don't have any coding skills in Linux ( I do know some java and c/c++ And I'm a fast learner )
In the past few days I've been setting up my first developing enviorment with Ubuntu 10.04 and learned a couple of things about android coding
Lets get back to the device
For now it's recognized as an HID device , and I can use getevent to get each function specific code
But nothing is mapped to any real function on the nook
Here is some info from the nook :

So , I have a few ideas on how to do it and I thought you might help me figure out the best way and guide me through it :
Using Tasker and write a script using Locale Execute plugin with getevent & other commands - Probably highly in-efficient and maybe slow?
Write an app to run in the background , intercept the events and execute commands every x ms? How much is needed for a quick response?
Write a driver ( or kernel module? ) for the device
Maybe I can use the HID driver to do that?
Port one of the sources I listed down to Android?
Another thing I haven't thought of?
I have found a couple of things that might help
powermate.c in dalingrin's kernel seems to contain some code for it but I couldn't find any real thing that it does to it besides define the device
GITHUB Link
Here are some source codes for Linux ( which I thought at first to be drivers but they seem to be handlers/applications )
https://init.linpro.no/pipermail/skolelinux.no/cinelerra/2006-March/005665.html
http://www.reynwar.net/gnuradio/epydoc/gnuradio.wxgui.powermate-pysrc.html
Can I use the code from USB Mouse support and adapt it for my own input device? will it even work on CM7 since it's built for Iconia?
I've also looked into usbled.c in the kernel , comparing it to the original code from here http://www.linuxjournal.com/article/7353
It seems pretty much the same , so maybe porting the handler is the best and easiest way?
Any help would be appreciated , in the last 3 days I've read so much on linux/android developing and still feels like I know nothing
Thanks ,
Gutz
will it work with the shuttle pro 2, too ?
There is a code for the shuttle pro and v2 as well here
http://www.reynwar.net/gnuradio/epydoc/gnuradio.wxgui.powermate-pysrc.html
Its an handler written with python , I need to find out if I can port this to Android
If I'll eventually port some of the code from there I'll try to include the v2 code aswell..
Did you get this going? Would be very interested.
oh memories
I did get this going eventually pretty easily using an app called "usb/bt joystick center"
I tried looking for it but it's not on the play store anymore , a google search did came up with some apk sources so just try them out
If you need any help pm me - I haven't touched it in years but I might remember / can dig up some old files to help
Good luck
Any news on that old topic ?
I just bought a ShuttleXpress for a Nexus in car project thinking it would be straightforward, but it seems that its not..

@hassbruk I have written a driver for this, which is implemented in my controller app. Checkout my github (freshollie) for more info.

Yes, all harpia variants running all Marshmallow ROMs (stock and custom) should work with r18. A Nougat-only version will be coming later once I bring CM14.1 to this device.
I'm trying it now. No issues so far.
Just in case, how I would I could go back to stock kernel?

@squid2, Your kernel is very good, is it possible to overlock?
Just wanted to say this kernel is amazing. Not sure how accurate the seetings for the battery are but it says I have 4 days remaining at 86%. Even if its half that its still a massive improvement, thanks for your devotion and work on the g series @squid2.
You are ruling the harpia forum.
Great job
For whatever it's worth, I installed BaseMark OS II and ran a before and after test of the Nov 8 kernel. It slowed down the memory a bit. The first four columns are stock and the last four columns are with the Nov 8 kernel.

For such a big hit to the memory score, it didn't affect the rest all that much. I wonder if there isn't some boost in battery life that I'm not sure how to measure. I didn't notice much warmth from the phone while running the benchmark, but I didn't really make a good test of that. If the battery life is xx% better, then it's a choice of what you value.
Please don't take this as being negative. I really appreciate the chance to try this out. Keep going Squid! I'm dying to see the CM's going on this phone!!
Hello @squid2 sir
I can't find any undervolting commit on github
Can you help me find it ?
Sent from my Motorola Moto E using XDA Labs
Should I be seeing better battery life when compared to stock? Because it looks to be worse (higher consumption when using, like wifi browsing). Do I have to change the governor?
Also, if I switch back to stock kernel, do I have to reset something (like some settings)?
I guess that the kernel wasn't the differentiating factor, as I just got similar performance as with stock - 3 days standby and 10 hours screen on time.

No need for setting anything when going back to stock kernel.
I'm wondering if this kernel makes it possible to use the white battery LED as notification LED?
To me the G4 Play's only flaw is not having a notification LED, but an "battery is being charged" LED... Very odd.
yeah this would be cool

I second this. I found it really odd how it's charging only, but not for notifications. I really would love to see if anyone could incorporate a notification light setting
Is the carging led somewhere at the bottom left of the phione? I can see something beneath the glass (looks like the proximity sensor), but mine is not lighting up when charging...

It's in the slightly on the bottom left side when plugged in. Surprised me the first time I installed CM after running stock for a little while, I didn't see a setting in the stock rom for it.
VPN disconnect reboot
I found a reproducible bug that causes a reboot with the r18 kernel. When using the built-in Android VPN feature the phone reboots as soon as I click disconnect. I tested with the stock kernel and it works fine, also tested with and without SuperSu. Phone is a xt1607 running stock ROM 6.0.1. The VPN type is PPTP.

I'm wondering if this kernel makes it possible to use the white battery LED as notification LED?
To me the G4 Play's only flaw is not having a notification LED, but an "battery is being charged" LED... Very odd.

and so on...
The device does not react to "upgrade" button and SD card inserted.
Can anyone help me what should I do to unbrick my Wetek?
Thank you in advance.
