I would offer some help, but without source or an answer to the previous question it seems I can't.

Thanks for the offer

Greatly appreciated. The stuff I have to figure out is not really related to the HAL module, as I already have software encoding working. It is w.r.t stagefright hardware encoding support. Anything you can offer in terms of tips from prior experience would go a long way. Sorry, I missed your question earlier. I thought I had posted the reason in the other thread and a smaller version in the first post. But here is the main difference between the other work and the work tracked in this thread. The other work was a complete compile from source code to integrate the source corresponding to libcamera.so and the hal new code requirement in ICS as one HAL module. This thread tracks work to make existing libcamera.so stuff from gingerbread work in binary form, with as little device specific stuff as feasible. That was the reason I had mentioned that this may or may not work with 3.0 kernels as it requires the gingerbread libcamera.so to be compatible with the 3.0 kernel due to the HAL module's hard dependency on libcamera.so.

I wasn't referring to your other thread, I was referring to the HD2 thread, which based on this explanation does the same thing.
Also, tips from previous experience will be useless without any form of code to relate them to. It sounds like going to a lot of trouble to keep the source concealed until such time as it can be released as a finished product rather than assist in the general progress of getting the camera to work in general.

twistedumbrella is right.
Don't you fear that we will not give you propper credit, since you developed your fix the use of ICS on HD2 has increased great time!
Everybody who is serious with flashing his HD2 with the latest goodies knows the name rapmv78

So unless you don't have any other reasons, I think it would be really beneficial to all of us if you guys could work on this final fix together.
I am sure donations will flow in your direction as soon as this is done...

ICS with Qualcomm Processor

Rapmv78 Hello, I wanted to know if a rom ICS already developed with Qualcomm Adreno 220 processor and the processor can help you arrange Nexus One and Desire.

If you can help please contact me at ale@miui.it .

Well, I am not worried about credits or anything of that sort. Just did not want to release incomplete stuff and unclean code. Thats all. If someone can tell me a better way than a tarball to share the code, that would be great. Have been looking at using github for a while. For starters, I can use some newbie tips on how to use github, without much uploading and having to re-sync a brand new repo

To be precise, I have started to use the everlov repo to be able to get the latest stuff, how do I create just the camera stuff into my github using the same repo url as evervolv?

Go to evervolv's github and pick the project containing the original files that match the ones you modified. Make sure you signed up for a github account first, and then click fork in the upper right of that project. This will create a page of your own that has their current files as a base.

To prevent cloning the wrong files and such, it is best to also set a default branch, by clicking Admin and on the new page selecting it from the list

After you pick one from the list, clicking back to source will save the change
Next you will want to clone those files to a folder somewhere on your computer, but not the one you were already working in or you will lose what was there. For that, your best bet is to look at the new page that just popped up when you did the fork and grab that address listed under the main menu and do

Code:

git clone "the project url"

Once that makes the folder, you can take your files and overwrite the ones you just cloned with them, but make sure you dont just overwrite the entire main folder or it will delete the .git folder which you need. Finally, you can commit the changes with

Code:

git commit -a -m "I haz changes"

and then push it to your new fork with either

Code:

git push git@github.com:"username"/"project name".git HEAD:"branch" -f

if you have set up keys or if you have not gotten there yet just

Code:

git push

will prompt for the login and password and push the files to the current project (the folder you are in) and the current branch (whatever you set to default before cloning).

Feel free to come to join #evervolv or #building_ics_source on freenode irc and twisted, drew, myself, or someone can help you get setup on github.

You did pick a good base to work from. These guys do great work.

Got video to work finally with hardware encoder support as well. It is not as smooth as I would like it to, but I do not know what the issue is. I could see that all frames were encoded, so the issue is probably in the encoder or my SD card is slow. Would like some feedback on whether others see some stutters too or not. Updated the second post with new fastboot system images. Also source code is now available on my github, as promised

DISCLAIMER: The code has a bunch of hacks and is not very clean, as I did not get much time to clean it up before sharing.

For people with non-nexus devices, you can use the source code to compile your own or here is just the HAL module as a separate download

http://www.mediafire.com/?87nizd1jrx01j49

You also need

media_profiles.xml which should to into /system/etc/

http://www.mediafire.com/?ig6t931i8h3zhzf

libmediaplayer.so which should go into /system/lib/

http://www.mediafire.com/?8jb64a94tdfe4vp

Here are the source changes for libmediaplayer.so
--- a/frameworks/base/media/libmediaplayerservice/StagefrightRecorder.cpp
+++ b/frameworks/base/media/libmediaplayerservice/StagefrightRecorder.cpp

uint32_t encoder_flags = 0;
- if (mIsMetaDataStoredInVideoBuffers) {
+ if (0 && mIsMetaDataStoredInVideoBuffers) {
encoder_flags |= OMXCodec::kHardwareCodecsOnly;
encoder_flags |= OMXCodec::kStoreMetaDataInVideoBuffers;
}

Enjoy!!

mulerokeh · Jan 11, 2012

downloading, feedback soon..

thank you..

ehh, how to install?

fastboot flash system file.img

just like that?
sorry, noob question..

geenyous · Jan 11, 2012

ok, I installed by replacing the camera.qsd8k.so file in system/lib/hw, changed the permissions to rw-r-r and then rebooted.
The attached pic is what I get when going into camcorder plus when I press the record button nothing happens at all...
Zoom appears to work though.
Cam still works fine. You can find my specs in my sig and a log attached.

furius · Jan 11, 2012

yeah!
I would like to try this without installing all the img system from second post ... is there a way to flash only the camera related files on MeDroid v4.2?

is that mean we only need copy this file to lib/hw?
edit: sorry! i saw the source

Glen_H · Jan 11, 2012

I have the same problem geenyous has with new camcorder.
adb pushed the file, changed permissions and rebooted.

I'm on a HD2 (eu)

did you try playback of recorded video on ICS? try also on pc or GB, ICS doesn't have HWA, only soft. Maybe that's the case of stuttering/chopped frame playback.

I have recorded a vid on CM7.2 GB /playback=perfect framerate. I playback the same file with same video player on ICS and i have stuttering/chopped frames.

I imported your source to the ics branch of my existing qcom camera repository https://github.com/TwistedUmbrella/android_hardware_qcom_camera to start working on making it "generic"
I am assuming the Build-libcamera := nexus tells it to use the included libcamera-nexus.so, so the first step will be redirecting a device proprietary to that folder under the name legacy and aiming it to pick that up instead.
The only reference I don't have a clear understanding of is camera-inc

Actually the stuff is already pretty generic, except for the hardware accelerated copying. camera-inc was for droid incredible, but what I found is that the library for the exact device does not really matter. So, for other devices, all you need to make sure is that the hardware accelerated copy works and may be a few additional flags need to be set and that should be fine. All I have is a nexus one, so cannot really be very sure about it though.

You need the right media_profiles.xml file and libmediaplayer.so (NOTE: this may not be compatible with your ROM and may boot loop. It is based off evervolv's code base), the links for which, I just added to the post. The media_profiles.xml file needs to go into /system/etc/ and the other file into /system/lib/. However, it may still not work as I do not know the state of the hardware encoder libs for your ROM.

I had the same problem as geenyous, now I installed the media_profile.xml from evervolv’s (github). Now I get a proper preview but recording stops immediately.

I don’t found any libmediaplayer.so, are you meaning libmediaplayerservices.so? Which libmediaplayerservice.so is suitable for the HD2 with tytung ICS 4.0.3?

Thanks
