This article or section needs language, wiki syntax or style improvements. See Help:Style for reference.

Reason: Numerous style issues, see Help:Style (Discuss in Talk:IOS#)

The purpose of this article is to demonstrate the use of iOS devices with Arch Linux.

## Installation

Install the libimobiledevice libraries and optionally ifuseAUR the mounting utility

## Connecting to a device

### Usbmux daemon

`usbmuxd` is required to make connections to iOS devices all. systemd comes with udev rule to automatically start and stop this daemon so no user interaction is required.

Insert the iOS device and verify that `usbmuxd.service` automatically started.

    systemctl status usbmuxd.service

    ...
    Active: active (running) since Sun 2020-01-19 19:23:18 UTC; 22s ago
    ...

### Pairing

In order to be able to connect to the iOS device, it must be connected via USB to the computer.

Note: Device screen must be unlocked

    idevicepair pair

    SUCCESS: Paired with device d8e8fca2dc0f896fd7cb4cb0031ba249

If you have multiple iOS devices connected `--uuid ios_uuid` parameter can be passed to target specific device.

### Application integration

Applications which use GVFS, such as some file managers (GNOME Files, Thunar) or media players (Rhythmbox) can interact with iOS devices after installing the gvfs-afc and gvfs-gphoto2 packages. Restarting the file manager or application might be needed.

### Manual mounting

Install the ifuseAUR package.

#### Mounting the media directory

The simplest way to mount your iPhone's filesystem to your mount folder, is using the following:

     # ifuse -o allow_other mountpoint

If you do not use the allow_other option, you will not be able to access the mountpoint folder, even if you attempt to sudo into it.

Application documents are not included in the iPhone's media directory and are mounted separately.

#### Mounting application documents

To list all available applications (and their APPIDs), run the following:

     # ifuse --list-apps

For example, if VLC is installed on device, you can mount VLC's files:

    # ifuse --documents org.videolan.vlc-ios mountpoint

`org.videolan.vlc-ios` is the APPID listed in the output of the previous command.

The mountpoint field is where you want to have it mounted.

## Changing iPod mountpoint

Traditional iPods are accessed just like a normal USB storage device containing a vfat file system (in rare cases hfsplus), and can be accessed as such. See the USB storage devices article for detailed instructions.

Tip: If you cannot see the iPod file system, it is likely that it is hfsplus formatted. For convenience, as Arch kernel is built with no support for that filesystem, you might want to restore your iPod using iTunes on Windows. This will erase all data on your iPod, and format it as a vfat filesystem

If udisks2 is installed, it will mount an attached iPod to `/run/media/$USER/iPod_name`.

If the volume label of the iPod is long, or contains a mixture of spaces, and/or lower-case and capital letters, it may present an inconvenience. You may easily change the volume label for more expedient access using `dosfslabel` from the dosfstools package:

- Get and confirm the current volume label:

    # dosfslabel /dev/sdXY

- Set the new volume label:

    # dosfslabel /dev/sdXY ArchPod

- Unmount the device:

    $ udisksctl unmount -b /dev/sdXY

- Mount it again:

    $ udisksctl mount -b /dev/sdXY

where `/dev/sdxx` is the current device node of your iPod.

## Importing videos and pictures

Both videos and photos can be found in typically in `<mountpoint>/DCIM/100APPLE`.

### HTML5 videos

Typically you want to convert MOV files to a HTML5 video format like OGV using ffmpeg2theora. Note that the creation date metadata is not in the converted video, so you need to use a script like:

    #!/usr/bin/sh

    find -name "*.MOV" | while read mov
    do
        d=$(gst-discoverer-1.0 -v $mov | awk '/datetime:/{print $2}' | tr -d \")
        base=${mov%.*}
        if test -f $base.ogv
        then
            touch -d${d} $base.ogv
            ls -l $base.ogv
        else
            echo $base.ogv missing
        fi
    done

And use `cp -a` or `rsync -t` in order to preserve the file's date & time.

### Importing pictures and deleting them

You can move photos and videos out of `<mountpoint>/DCIM/100APPLE`, however you need to trigger a rebuild of the "Camera Roll" database by deleting the old databases.

    # cd <mountpoint>/PhotoData
    # rm Photos* com.apple.photos.caches_metadata.plist

## Converting video for devices

### Handbrake

Handbrake is a nifty tool with presets for a variety of iPod versions. CLI and GTK versions are available with the handbrake-cli and handbrake packages respectively.

If you do decide to take the CLI way, a good guide is available at https://handbrake.fr/docs/en/latest/cli/command-line-reference.html.

### Avidemux

Install the avidemux-qt package.

This can convert to mp4 files. If you enforce a hard max of bit rate @ 700ish and keep the video size to 720x480 or 320x240 than it works fine for video file exporting.

### Mencoder

Install the mplayer package.

Has extremely comprehensive configuration support, which will be able to spit out iPod-compatible video files. Check out mencoder(1); a lot of MPlayer opts will also affect encoding.

A basic guide is also available at MEncoder.

An example command to encode iPhone/iPod Touch-compatible video:

    mencoder INPUT -o output.mp4 \
    -vf scale=480:-10,harddup \
    -oac faac -faacopts mpeg=4:object=2:raw:br=128 \
    -of lavf -lavfopts format=mp4 \
    -ovc x264 -x264encopts nocabac:level_idc=30:bframes=0

### FFmpeg

Install the ffmpeg package.

Another encoder with comprehensive configuration support. Example command to encode for 5G iPod:

    $ ffmpeg -vcodec xvid -b 300 -qmin 3 -qmax 5 -bufsize 4096 \
    -g 300 -acodec aac -ab 96 -i INPUT -s 320x240 \
    -aspect 4:3 output.mp4

or iPod Touch/iPhone compatible video output:

    $ ffmpeg -f mp4 -vcodec mpeg4 -maxrate 1000 -b 700 -qmin 3 -qmax 5\
    -bufsize 4096 -g 300 -acodec aac -ab 192 -s 480×320 -aspect 4:3 -i INPUT output.mp4

## Device specific

### iPhone/iPod Touch

By default, neither the iPhone nor the iPod Touch present mass storage capability over USB, though there is a solution for accessing your files.

The proposed solution is to use a FUSE file system called ifuseAUR, which allows you to mount your device through USB, as you normally would. After installing ifuse, for instance, you should see your iPhone appear in the left navigation of Gnome Files and other supporting file managers.

Tip: You can also use other #iPod management apps to transfer pictures and music.

Refer to this page:[1]

#### The iFuse Way

Note: If your device has a screen password, you must unlock the device to gain access through the USB interface.

Install the ifuseAUR package.

Now make sure that you have the fuse module loaded by doing `modprobe fuse`, assuming that you do not have it in `/etc/modules-load.d/` already.

You can now mount your device. Make sure it is unlocked before you plug it in, or it will not be recognized.

    # ifuse <mountpoint>

The mountpoint field is where you want to have it mounted.

And you are done! You should be able to point your syncing software of choice to the mount point and be able to transfer files.

To unmount your device:

    # umount <mountpoint>

Members of group `fuse` can mount devices as regular user:

    $ ifuse <mountpoint>

To unmount:

    $ fusermount -u <mountpoint>

#### Generating HashInfo file

If you have never synced your device using iTunes, you will get error messages telling you that the HashInfo file is missing. This can be fixed by syncing once with iTunes in order to create it. Alternatively one can create this file using the site http://ihash.marcansoft.com/. Enter the serial number of the iPod on the website. It will generate a file named `HashInfo` which you will place under the `/mnt/ipod/iPod_Control/Device/` directory. Unplug the iPod device and plug it back.

#### Unobfuscating the Database

Since firmware version 2.0, Apple has obfuscated the music database. If you are using recent firmware, the file `/System/Library/Lockdown/Checkpoint.xml` can be modified to enable use of the older, non-obfuscated database. If that file does not exist then try to copy from `/System/Library/CoreServices/Checkpoint.xml` to `/System/Library/Lockdown/Checkpoint.xml` then replace:

    <key>DBVersion</key>
    <integer>4</integer>

with:

    <key>DBVersion</key>
    <integer>2</integer>

Then reboot your device.

If syncing fails with "ERROR: Unsupported checksum type '0' in cbk file generation!", you may need to leave this at 4. libgpod seems to expect a hashed database.

### iPod Classic/Nano (3rd generation)

You need to set up the iPod to make libgpod able to find its Firewire ID. For this, you will need to get your FireWire ID manually

1) Mount the iPod as a rw mount point. In the following example, use `/mnt/ipod`.

2 ) Find the serial number by typing

    # lsusb -v | grep -i Serial

this should print a 16 character long string like 00A1234567891231 (it will have no colons or hyphens)

3) Once you have that number, create or edit `/mnt/ipod/iPod_Control/Device/SysInfo`. Add to that file the line below:

      FirewireGuid: 0xffffffffffffffff

(replace ffffffffffffffff with the 16 digit string you obtained at the previous step and do not forget the leading 0x before the string)

Your iPod can now be managed with Amarok or gtkpod.

### iPod Nano 5th generation

Follow the instructions above #Generating HashInfo file in order to set up the hash file, it is needed to write into the device music library. To be able to use the iPod Nano with libgpod, a `SysInfoExtended` file is also needed to be placed in the directory `/mnt/ipod/iPod_Control/Device/`. It can be generated using:

     # ipod-read-sysinfo-extended bus device mountpoint

for example:

     # ipod-read-sysinfo-extended 001 011 /mnt/ipod/

### iPod Nano 6th generation

By default libgpod does not seem to be able to syncronize on a iPod Nano 6th generation. It copies data, but as soon as USB is disconnected, everything is as before. The package libhashab-gitAUR fix this.

### iPod Shuffle 1st and 2nd generation

Due to the simple structure of the Shuffle (compared to the "big" iPods), it is possible to use the player almost like any other USB flash MP3 player. What is necessary is rebuild_db.py file stored in the iPod's root directory. Simply copy MP3 files onto the iPod Shuffle (sub-folders are allowed too) and run:

    $ python2 /path/to/rebuild_db.py

Source

### iPod Shuffle 4th generation

In order to use this version of the iPod Shuffle under linux, you can use the python based command line tool ipod-shuffle-4gAUR. It also provides advanced voiceover and (auto)playlist generation support.

### iPod Video (5th and 5.5th generation)

iPods in the mainline series up to and including this model do not support the AAC PNS feature, and will display audible artifacts when encountering it. Disable the feature in ffmpeg when encoding AAC files for these devices.

    $ ffmpeg -i input.ogg -c:a aac -b:a 256k -aac_pns 0 -movflags +faststart -vn output.m4a

The `-movflags +faststart` options place the moov atom at the start of the file, which helps the iPod parse the file faster.
