MP4 Videos vom eigenen Webserver iPhone tauglich machenEnable your webserver to feed iPhone with MP4 videos

23.03.2010 Leave a Comment Written by Wolfgang

Ich verwende iPhone OS 3.x und hatte Probleme .mp4 Dateien direkt im Safari auf dem iPhone angezeigt zu bekommen. Ich habe verschiedenste Einstellungen beim Encodieren ausprobiert, aber immer wenn ich im iPhone Safari auf einen .mp4 Link auf meinem Webserver geklickt habe, kam die Fehlermeldung “Diese Datei kann nicht heruntergeladen / angezeigt werden”. Nach intensiver Suche im Internet fand ich dann Hinweise, dass es evtl. mit MIME types und der Apache Konfiguration zu tun haben könnte.

Lösung:

  1. Video für iPhone / iPod Touch encodieren (Compressor, Quicktime, Adobe Media Encoder, …)
  2. Video auf dem Gerät testen! (zur iTunes Library hinzufügen, aufs iPhone spielen und anschauen)
  3. Video auf den Webserver hochladen
  4. sicherstellen, dass folgende Zeile in der Apache Konfiguration bzw. in einer .htaccess Datei drin steht:
AddType video/mp4 mp4 mp4v mpg4 m4v

Das war’s, nun sollten .mp4 Videos vom Webserver als progressive Downloads (wieder) auf dem iPhone angezeigt werden können.

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:
AddType video/mp4 mp4 mp4v mpg4 m4v

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

Update von iPhone Applikationen in iTunes 8.1.x funktioniert nichtiTunes 8.1.x login loop when trying to update apps in appStore

29.05.2009 Leave a Comment Written by Wolfgang

Seit einiger Zeit funktioniert bei mir im iTunes das Update von Applikationen im AppStore nicht mehr. Ich bekomme zwar die Meldung, dass es neue Updates für meine iPhone / iPod Touch Programme gibt, aber immer wenn ich auf den Link klicke, komme ich in einen Loop. Das Loginfenster öffnet sich, ich gebe meinen Usernamen / Passwort ein und danach kommt das Fenster wieder und wieder und wieder und wieder …

Heute habe ich endlich hier die Lösung gefunden!

Ziemlich am Ende des Beitrags hat der User “X Rookie” den richtigen Hinweis gepostet. Das Problem war weder die Schuld von iTunes, noch von Mac OS X oder sonstwas, nein der Verursacher war NetBarrier! Ich verwende es als meine private Firewall und bin auch zufrieden damit, aber irgendwie war eine Option in den privacy settings vom Programm aktiviert, die das ganze Problem verursacht hat – und ich hab’s nichtmal selbst gesetzt 🙁

AppleID privacy setting

Nachdem ich “Hide my AppleID when using iTunes MiniStore” deaktiviert habe, haben die Updates im appStore in iTunes wieder problemlos funktioniert 🙂

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 🙁

AppleID privacy setting

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

Revert an iPod Touch (iPhone) to a previous Firmware Version

22.04.2009 Leave a Comment Written by Wolfgang

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)

Fixing iPod (Touch) sync on error “cannot enable syncing – Override/Ok”

06.10.2008 1 Comment Written by Wolfgang

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.

Manipulate your mpeg-4 files for iPod Video

23.05.2006 Leave a Comment Written by Wolfgang

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.
