Hey Tytung, is 720p recording kernel related because I wasnt able to save the video once it was captured on my Nexus one port. I would hit stop button and the phone would freeze up and gallery would force close.

Only 720p video playback. No 720p recording.
I think you are talking about hardware video recording. Yes, it's kernel related.

Update:
For working hardware video recording, a kernel with pmem instead of ion is required.

Dang, I was hoping maybe that I'd have working video recording on my Nexus One. Btw, I've linked this thread on my xda post and I plan to link your donation link too. Thanks for the hard work, but unfortunately I won't be able to reap all the benefits of it as I have no idea how to modify the kernel to get recording/720.playback working

So I'm using an evervolv kernel that is not using ion. How hard is it to modify the kernel to get hardware playback/video recording? Video recording itself isn't choppy, but the video doesn't save.

Ion memory allocator is newer than pmem memory allocator, but proprietary (close source) camera libs are designed for pmem.
So you need a kernel using pmem memory allocator.

Evervolv kernel should be using pmem before, and then Ion was added by someone.
Thus you might revert some commits to go back pmem.

Evervolv actually stopped using ion as soon as they started 4.3. I think that's why I was able to get your ROM boot g

If so, you could read those three xda URLs I provided above.
First, you may need to identify if you see the following error in the logcat.
venc_drv_open::224 VENC_DRV_OPEN: FAILURE:venc_ioctl_initialize_done_recved FALSE.
Then try to revert qdsp6 source code.

BTW, which evervolv kernel git do you use for N1?

I just took the Evervolv kernel from their latest nightly. I'll check the logcat tomorrow. One last thing, I probably need to decompile a jar, but do you know why button lights aren't working for me? I changed the Leo lib with the passion one, and yet lights don't seem to work. Other than that your ROM is just pure awesome.

Please type "ls -l /dev | grep pmem" to check if you see pmem or not. If you see them, pmem is used by the evervolv kernel.

Did you use initrd.gz from my NexusHD2 ROM or from a N1 ROM? There're some settings for button lights in the initrd.gz.
Besides, maybe /system/etc/init.d/99_button_light_off can be used by HD2 only.
If you include it in your N1 port, please remove it and try again.

You were right, I just needed to remove the button_light_off script and the buttons tarted working. What is that for anyways?
