From the Microsoft Expression Encoder download site:

“Microsoft^® Expression^® Encoder, a feature of Expression Media, offers encoding, enhancement, and publishing of rich media experiences to Microsoft Silverlight. “

Features Include:

Better Encoding

VC-1 advanced authoring SDK integration: by adopting the new VC-1 authoring SDK, Expression Encoder 2 is able to author better quality video faster. We’ve exposed a set of presets for tuning the encoder as well as detailed settings with comprehensive tooltips for the advanced compressionist.

New profiles, and video codecs for streaming media: Encoder 2 supports a number of new modes and codecs including Quality VBR, WMA Pro (stereo), WMA Lossless, 24 bit audio and audio/video encoding stream selection.

• Improved MPEG source support: We now include an MPEG 2 decoder in the product to give a consistent story across platforms. The decoder we ship supports transport streams (so you are able to work with sources that originated from HDV cameras. Seeking performance and accuracy has been greatly improved.

Instructions for creating the playlist file:

1. Open up a text editor such as Windows Notepad

3. Type in the FULL path to the Web Address (URL) of your MP3 or WMA music file.

If it’s an MP3 music file, type it in like this:

http://media.gravlab.com/editorialemergency/sample.mp3

Repeat for each mp3 you want to add
http://media.gravlab.com/editorialemergency/sample.mp3
http://media.gravlab.com/editorialemergency/sample.mp3
http://media.gravlab.com/editorialemergency/sample.mp3

Save this text file with an .m3u (universal playlist) extension.

Example: playlist.m3u

There is no limit to how may songs you can include in an individual playlist. In a playlist with more than one song, each song is buffered and streamed individually. Therefore, it makes no difference how many songs are referenced in one playlist file. Each song will play one after the other without user intervention. Also, in a playlist with more than one song, the site visitor can use the Media Player controls to skip forward or back a track (song) in the playlist, and also has the option of “previewing” a short clip or a series of short clips of each song in the playlist.

Link to the m3u file (you can put the .m3u file in your GravityLab account or on your website server, it makes no difference)

We often are asked about custom embedding of audio files from your account into your website. We do have a Flash file that can automatically load an mp3 playlist into a flash player based on an XML file.

GravityLab Multimedia offers MP3, Windows Media, and Quicktime Streaming services. Contact us today for a quote or choose from one of our audio hosting plans to embed audio into your web site.

The GravityLab Multimedia content delivery network is comprised of best-of-breed streaming media servers located directly on the fiber optic North American internet backbone. What that means, basically, is that your media content is delivered on demand very quickly to a global audience using the best Internet path directly into their homes.

You are able to deliver all the major streaming media formats from one account. You simply FTP your video to your account, and then link to your video or audio assets from your web site. We try to make it as easy as possible for you to deliver streaming media to your audience.

Once you open your account, within 24 hours you can begin uploading your video. If you need your video encoded to streaming media formats, we can do that as well from your source media.

Linking to mp3 Streams

Linking to mp3 streams from your mp3 hosting account requires a text file with the extension .m3u. This file has the URL to your mp3 stream in it. For instance, if a mp3 playlist named “Blues” was playing from the Streaming Server, and the domain name of the server was stream.mydomain.net, the m3u file would contain the link:

http://stream.mydomain.net:8000/blues

The “:8000″ is the port for streaming mp3 playlists from Darwin Streaming Server. If you enable port 80 streaming the “:8000″ is not required. The .m3u file could be placed on any web server, and linked to a web page with the standard tag. For instance, to link to a file named “blues.m3u” from a web page in the same directory with the file, the link could be:

Play the blues

Note: For .m3u files to work correctly, your web server must be configured to deliver the correct mime type for .m3u files:
audio/x-mpegurl .mp4

Microsoft Internet Information Server 3.0

If you are running Windows NT Server and IIS 3.0 and want to configure the MIME types, create a registration entry file with a .reg file name extension:

1. Open Microsoft Notepad or another text editor.
2. Type in the following text. (Do not cut and paste the text from the Web page.)

REGEDIT4

[HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet
/Services/InetInfo/Parameters/MimeMap]

“video/x-ms-asf,asf,,5″=”"
“video/x-ms-asf,asx,,5″=”"
“audio/x-ms-wma,wma,,5″=”"
“audio/x-ms-wax,wax,,5″=”"
“video/x-ms-wmv,wmv,,5″=”"
“video/x-ms-wvx,wvx,,5″=”"
“video/x-ms-wm,wm,,5″=”"
“video/x-ms-wmx,wmx,,5″=”"
“application/x-ms-wmz,wmz,,5″=”"
“application/x-ms-wmd,wmd,,5″=”"
3. Save the file with a .reg file name extension.
4. Double-click on the file to add the entries to your registry.
5. After creating this file, stop and then restart all IIS services.

Apache

1. Ensure that you have server administration privileges. If you do not have these privileges, ask your server administrator to update these MIME type extensions.
2. Change directories to /httpd/conf.
3. Edit the file srm.conf.
4. Add the following lines to the end of the file, or to where the other AddType video/* entries are found:

AddType video/x-ms-asf asf asx
AddType audio/x-ms-wma wma
AddType audio/x-ms-wax wax
AddType video/x-ms-wmv wmv
AddType video/x-ms-wvx wvx
AddType video/x-ms-wm wm
AddType video/x-ms-wmx wmx
AddType application/x-ms-wmz wmz
AddType application/x-ms-wmd wmd

If you add these to the end of the file, make sure that the file ends with a blank line.
5. Save changes and quit the editor.
6. Restart the Web server.

No. Windows Media Player 9 Series can play files in a wide variety of digital media file formats, but Windows Media Services 9 Series cannot stream all of those files. In certain cases, you may need to convert digital media files into a compatible format before you can stream them.

Servers running Windows Media Services 9 Series can stream files that are in the Microsoft Windows Media Audio (WMA), Windows Media Video (WMV), Advanced Systems Format (ASF), and Motion Picture Experts Group (MPEG)-1 Layer 3 (MP3) formats. However, Windows Media Services cannot use the intelligent streaming feature to stream files in MP3 format.

You can use a Windows Media server to stream files in other digital media file formats if the appropriate media parser plug-in is enabled. A media parser plug-in translates the information contained within the file to a format that can be used by the Windows Media server and Windows Media Player. To find out whether a media parser plug-in is available for the format you want to stream, contact the digital media file format developer.
