Securing your iPhone streams is easy with Encoding.com's stream encrytion option. We encrypt your TS segements using AES-128 with no need for an additional processing step. The encryption passes on delivery, as opposed to requiring additional processing time. You'll need a few things to get started, so let's lay out all the details:

1)  Create 32 character hexadecimal string. (Noted as 128 bit key below.)

     Sample encryption key: 243F6A8885A308D313198A2E03707344. Don't confuse this with API keys, as the encryption key can only contain characters A - F & 0- 9.

     Sample of encryption key that will fail immediately: COq8MA6wT3aHxEIvGy4U3VNBa3BMch29

OR

     Create a file that contains the hex string. If you choose a file, this will overrride the hex key specified in the request.

3) Request an HLS encode with the following additions:

<format>
    <!-- Format fields -->
        <output>[iphone_stream|ipad_stream]</output>
        ...
        <encryption>[yes|no]</encryption>
        <encryption_key>[128bit-key]</encryption_key>
        <encryption_key_file>[SourceURL]</encryption_key_file> <----Use a key_file or a string value. Don't use both, as the file will override the key. 
        ...
    </format>

Have a ton of videos that just require lossless rotation? Did someone have too much fun with the iPhone and shoot everything portrait instead of landscape?

Try this on for size. Lossless rotation for use with .mov --> .mov files only.

  <rotate>0</rotate>
  <set_rotate>90</set_rotate>

If you're interested in using Encoding.com's platform to create iPhone Streaming (m3u8) files from your source content, there's a number of ways to achieve that using the options listed below. Our new HLS encoding has better adaptive bitrate distribution within the H.264 segments!

There are a number of very popular mobile devices that support video playback including:

• iPhone / iPod
• Blackberry
• Nokia
• Droid
• PSP
• Zune

Of course, many of these devices have their own video format requirements.  Encoding.com provides simple presets for the most popular mobile devices so that you can properly encode your video for your target device without requiring you to research the various device specifications. Use our web interface to browse to the presets and choose from an encode flavor that you can use as-is, or customize however you'd like. Go ahead and create one watch folder and add multiple presets to create all of your mobile content. It's that easy!

We test video playback on a variety of devices, from Mac and Windows PCs, to all the various mobile phone platforms available today. One critical issue that comes up often is that the hosting server has not set the MIME types for the video type. A typical error message for this would be "unknown application/octet-stream". Here is a list of many common formats we encounter.

IMPORTANT: You will need to configure your ftp server to these MIME types for them to be properly recognized by their respective playback devices.

With TAR output is set to OFF, and should see .m3u8 pointers and .ts segment files populate your output directory. The trick is correctly formatting the output filepath. You have to make sure your output filepath has a filename WITHOUT a 3-character file extension. I had this same problem because I either defined only the output directory, or had an output filename with .m3u on it. In both cases that will force a TAR output even if you have set it to off. SAMPLES: To get your segments, a correct output filepath should look something like this: http://yourbucket.s3.amazonaws.com/iphonetest/outputfilename ftp://username:password@ftp.yourserver.net/iphonetest/outputfilename

You may want to check which model Blackberry you are using. This is a very useful PDF guide. http://www.pixelgoat.net/encoding/blackberry/Blackberry_Video_Profiles.pdf If you are still having a problem, please send us a ticket and include the Media ID# of the file which isn't playing for you. https://manage.encoding.com/user/#/user/support.php Verified settings include:

NOTE: mp3 audio does NOT play with video. Please use aac audio with mpeg4 to guarantee proper playout on Blackberry phones. We have successfully tested our base presets on Blackberry phones for mp4 and 3gp. Confirmed playout to Blackberry Curve 8530 in November 2010.

If a user is experiencing an issue using the iphone_streaming task/preset (see snippet of the full error read out below), this error is easily resolved by setting the audio_sample_rate. Apple recommends the audio_sample_rate is set to 22050, however, it could potentially be set to: 8000, 11025, 16000, 22050, 32000, 44100, 48000.

One of the reason may be inconsistency of specified segment duration and framerate/keyframe pair. You should try to keep at least 3 keyframes per segment. E.g. if you specify segment duration 5 sec and keyframe 15 fps, the keyframe parameter should not be greater than 25, so we have at least one keyframe per every 25 frames, and there are about 3 keyframes per segment (it's duration is 15*5 = 75 frames).
