video streaming

[mobilpress]

Hi,

I'm using Tera-Wurfl and it very good software.
Can you help me with this one:
I need to make detection of the phones for mobile video streaming.
For example some phones use h.263 codec.
Some of them: MPEG-4
And newest: h.264.

How to read suitable codec for video streaming (audio also) when we use Tera-Wurfl?

Thanks.

In order to detect the correct video codec to use, you need to check if the user's device supports one of the formats that you have encoded the video in. Let's assume you have all of your videos encoded in MP4 (H.264/AAC) and WMV (Version 7+). You could use the following code to display the supported streaming video format:

Code: Select all

<?php
$wurflObj = new TeraWurfl();
$wurflObj->getDeviceCapabilitiesFromAgent();
if($wurflObj->capabilities['streaming']['streaming_video']){
   if($wurflObj->capabilities['streaming']['streaming_mp4']){
      echo "file.mp4";
   }elseif($wurflObj->capabilities['streaming']['streaming_wmv'] >= 7){
      echo "file.wmv";
   }
}else{
   echo "Streaming video is not supported";
}
?>


A complete list of the available capabilities is available here.

Thank you Steve,

But I'm trying to understand this one:
We have mobile TV transcoding middleware and we have 3 types of output streams: h.263, MPEG4 and h.264.
Format:
rtsp://server.com/live_h.263.sdp
rtsp://server.com/live_MPEG4.sdp
rtsp://server.com/live_h.264.sdp

How to detect automatically which stream we will offer to users using Tera-Wurfl?

Thanks

}else{
   $link = sprintf('<a href="%s">Watch Video</a>',$link_href);
