Native support for Free Lossless Audio Codec in Android system. FLAC files can be used also as ring tones.
FLAC files play in the Music.apk and any other players that use the standard system services.

Kenny Root's patches adjusted and applied to 2.1_r2 platform source: FLAC on Android - Kenny Root
Compiled for compatibility with other Milestone system libraries.

Consists of:
/system/lib/libFLAC.so
/system/lib/libmediaplayerservice.so
/system/lib/libopencore_player.so
/system/framework/framework.jar - modified MediaScanner and MediaFile in android/media

Instructions

Automatic installation from ADBRecovery
Copy the unpacked ocflac folder to your sdcard.
Copy the included install.sh script to the recovery folder on your sdcard (so it's like this: recovery/install.sh - do not put it in the scripts subfolder).
Boot to recovery (power off,hold camera or X + power, then volume up+camera), apply update.zip (use d-pad and enter), then reboot.
Remove the install.sh file from the recovery folder.

Manual installation
Copy the unpacked ocflac folder to your sdcard.
From adb shell or terminal on the phone do:

backup:

mkdir /sdcard/ocflacbackup
cp /system/framework/framework.jar /sdcard/ocflacbackup
cp /system/lib/libmediaplayerservice.so /sdcard/ocflacbackup
cp /system/lib/libopencore_player.so /sdcard/ocflacbackup

modification:

su
mount -o remount,rw /dev/mtd/mtdblock6 /system
cp -f /sdcard/ocflac/framework.jar /system/framework
cp -f /sdcard/ocflac/libFLAC.so /system/lib
cp -f /sdcard/ocflac/libmediaplayerservice.so /system/lib
cp -f /sdcard/ocflac/libopencore_player.so /system/lib
chmod 644 /system/framework/framework.jar
chmod 644 /system/lib/libFLAC.so
chmod 644 /system/lib/libmediaplayerservice.so
chmod 644 /system/lib/libopencore_player.so
mount -o remount,ro /dev/mtd/mtdblock6 /system

Then reboot the phone. The first reboot will take longer than usual, be patient. Second reboot might be needed for everything to settle down.

The framework.jar has been disassembled and reassembled by JesusFreke's smali/baksmali.

The framework.jar might differ between different builds of Milestone system so I've assembled several versions, use the one appropriate for your build.

this flac hack only works in the default android player, it crashes "3: and btunes =(

[nadlabak]

FLACs play fine for me in both 3 and btunes. Only the seeking in btunes is broken. No FCs for me...

actually both program play the files , but 80 % of the times when you play the flac files the app crashes =/

[nadlabak]

Are you using the updated libraries for FLAC from 26.6.2010?
I'm not able to get a single crash, both 3 and btunes are perfectly stable when playing flac on my phone...

One more update:
The libraries have been updated again - the duration of a flac file reported by the mediascanner is finally correct.
This also fixes the broken flac seeking in the bTunes player.
