[MOD][PORT][N]aptX codec

[dh.harald]

Unfortunately, OP3 has no aptX license...
Unfortunately, CM roms have no aptX support...
Until now.

The whole aptX codec support is already present in Qualcomm Bluetooth stack, in Nougat... We need only some proprietary drivers to activate it.
... and I've found that libraries in a Moto Z factory images.

UPDATE
After a review process, this modification has (partially) merged to LineageOS

This should be interesting... but how about do i test if Aptx is enabled or not.. i do have a Sony MDR-EX31BN Which Supposedly has aptx and seemed to be working fine with my Sony Z3...
Any thoughts?

Check it in logcat...
Here's the related log in CM:
Selected Codec aptX
If I remember well, it logs SBC in same way...

 

[kcajjones]

This is incredible if it works properly!
Has anyone tried in open beta 9?

 

[theduke7]

seems to Works on OB9 further testing required, great find

 

[siankatabg]

Wow, this site with that amount of adds is almost unusable... Took me 5 minutes and maybe few MB spend on loading adds to download 140 KB zip file.
Anyway, good work. I'm waiting for my Bluetooth earphones and I'll test this when I get them in my hands Thanks.

 

[Miksel12]

Wow! Awesome work mate.

Does this port work with stock Roms, or is it even needed? I'm new to OnePlus devices, so bare with me, if this is a ridiculous question.

The libraries inside the zip are from android 7.0.0 and probably they will work on any 7+ rom including stock (ob8 and 9). If you have a Bluetooth device that supports aptX(like head/ear-phones) you might want to try it, if you don't have, then you don't need it
I should receive my earphones today, so I'll test this on OB9(already installed and it seems that aptX is correctly loaded based on the logcat). Will report later how it's going.

 

[qhsusb_bulk]

Using Meizu EP51 and open beta 9. It seems working . Very interesting.

 

[siankatabg]

I can confirm that aptX is working on OB9. Attached screenshot from the log with turning off and back on the Bluetooth and playing music after that (where the codec get initialized). Nice find and work OP, thanks again

 

[kiha]

Seems that it is working properly. I just check it on the cm 14.1 nightly (dec 18) with my meizu ep 51. Find a few rows in the logcat. I would like to attach screens from logcat, but i don't know how to do it (=

 

[Stupifier]

Instead of just looking at the Logcat to confirm working (a good way to check I admit),
Do you guys notice an improvement to sound quality? I mean, that is the Whole point of apt-x codec.....Much higher bitrate and such.

I Just downloaded a few songs in flac and listening it now. A quality is really awesome. I am really feel the difference

i was really excited until i realized that none of my devices support AptX (Pioneer head unit, jaybirds, and lots of other BT headphones/speakers)

 

[siankatabg]

It's seems that aptX(HD) is already included in A.R.I.S.E., so for those that use it, most probably you don't need this

P.s. - I'm telling this just for information, no disrespect for the creator

P.s. 2 - Little off topic, but if someone know for a way to see the battery stats of the bt set, please PM me (it works on IOS natively...). Thanks.

Apt-x HD codec is already included to xperia x performance, but different filename. (You need to rename it from *int* to *rel*) But unfortunately, I have no clue, is it working or not... (The key functions are present) If somebody has apt-x hd headset/speaker, i could attach that lib as well for try...

 

[AcmE85]

Go ahead, I'm sure somebody will profit from the given HD codec.

My point was that the arise users don't need to flash this (it may lead to some issues maybe, because of the different aptX codecs in the system). Anyway, I'm almost sure that aptXHD is backward compatible with the aptX and it picks the right codec depending on the paired device, so your idea to make another zip with the HD libs is good and if it works on aptX(without HD) device you can abandon your first one

P.s. - For some strange reason arise write different logd binary and now my logcat isn't working even after manually replace it with the stock one... So I can't see if the HD one work on my aptX earphones (no difference in the sound with your zip that I've tested before that, so it might work).

If you need I can extract them from the zip to test them too?
