I’m using iPhone OS 3.x on my iPhone and recently i had problems to get my .mp4 files displayed in mobile Safari. I tried different settings for encoding the files but not a single one worked. When i clicked the link to the .mp4 file in mobile Safari, all i got was the “file can’t get downloaded” error. After some googling i found a clue that it might has something to do with MIME types and the apache server hosting the videos.

Solution:

1. encode your videos for iPhone / iPod Touch (Compressor, Quicktime, Adobe Media Encoder, …)
2. test them on the device (add the video to your iTunes library and upload it to your iPhone and watch it!)
3. upload the video to your webserver
4. make sure you have the following line in your apache config or in a .htaccess file in your directory on your webserver:

1

AddType video/mp4 mp4 mp4v mpg4 m4v

That’s it, now progressively watching .mp4 videos from your webserver on your iPhone should work (again).

For quiete some time it bothers me that i’m not able to update apps for my iPhone / iPod Touch directly in iTunes. I get a notification that some apps have been updated, but when i click on this link, i enter the infinite loop of login to the appStore: i enter my username / password correctly, but get the login window again and again and again …

Today i finally found a solution for that problem here.

Nearly at the end of the thread user “X Rookie” got the right hint for me. The problem wasn’t iTunes or Mac OS X, the problem was NetBarrier! I use it as my personal firewall and like it, but somehow a setting in the data privacy part of the program caused all the trouble and i didn’t set it

After unchecking the “hide my AppleID when using iTunes MiniStore” checkbox, the problems with the appStore updates are gone

Here’s how to revert to a previous firmware version on your iPod Touch (iPhone?), even when apple states in it’s release notes for the new (beta) firmware that it’s not possible to revert

The trick is to correctly enter your iPod into the DFU (Device Firmware Update) mode.

• start iTunes
• connect your iPod to your computer
• press the power button and home button down for at 10 seconds
• release the power button and?keep the home button pressed until iTunes shows a message that it has found an iPod in recovery mode
• option – click on the restore button in iTunes
• select your firmware file (in my case 2.2.1), if you can’t find it, download it here and rename the .zip file into .ipsw, then select it in iTunes
• the firmware update starts, but keep patient! (sometimes it seems nothing happens, but wait, you will see it does)

Today i plugged my iPod Touch into my USB port and got an akward error saying iTunes cannot sync my iPod because syncing is disabled and asked me to enabled it. I clicked yes and got a second dialog saying “Cannot enable syncing” and i could click “Override” or “OK”. The odd thing: both choices yield no success and i was left with a sync of my iPod but without my addresse, calendars, bookmarks being synced

After some research and luck i found this solution:

First i repaired my file permissions using Disk Utility, even restarted and run the command again -> no luck, but as found here it helped other people.

Then i found out that not only iTunes stopped syncing, iSync itself reports an error message when starting. The message was “Sync Services: Can’t connect to the sync server …” Luckily i found the topic “iSync can’t be launched” at the Apple Discussions.

I deleted ~/Library/Application Support/SyncServices/Local/ and restarted iSync. It took some time to recreate the Local folder, but then iSync started and the syncing in iTunes works again. Just had to enable the syncing for address book, … for my iPod on the “Info” tab.

AtomicParsley is a freeware commandline tool for Mac OS X as well as for Linux and Windows (cygwin). It allows to manipulate the metadata in mpeg4 files (m4a, m4b, m4p, m4v & mp4) and in 3GPP files.

It’s very handy if you like to generate or manipulate the metadata in movie files to provide iTunes-like metadata automatically on a server. It even can turn your selfmade movies into “video podcasts” or “movies” inside your iTunes library like the movies you downloaded from the iTunes Music Store.

myTunes is a donationware program written in JAVA and runs both on Mac OS X and Windows with your iTunes. It acts as a small webserver which creates RSS2 feeds with enclosures (aka podcasts) from your iTunes library and even from each of your playlists!

For what do i use it?

I use it to stream my iTunes Library across my wireless LAN to my Sony PSP to listen to my music while walking around in my house It’s really great for that purpose because the webserver fits nicely into the PSP screen, is easy to navigate and you can even search for songs or artists! I really like this piece of software – give it a try.

Steve Jobs demonstrated a version of iTunes integrating PodCasting support which should be available “within about 60 days”.

There’s only one thing to say: Apple keep up doing with what you’re doing!
