IIS Configuration

Follow the instructions in this topic to configure the basic operation of Internet Information Services. These customizations configure streaming features and allow user upload of large media files.

Configure HTTP Delivery

Audio files and HTML5 playback will be delivered over HTTP. Wowza Media Server doesn’t deliver content over port 80, so IIS needs to be configured to deliver it.

1. Open IIS by clicking on the Windows icon —

2. Type Internet Information Services and click IIS Manager when it appears.

5. Click on the main server node in IIS. On the right side of the main window, open MIME Types.

6. On the right side, click Add.

7. Enter the file extension .mp4. For the MIME type enter video/mp4.

9. At the left of the IIS window, select the HML site and click Bindings on the right side.

10. Click Add and enter the IP address for Wowza along with the URL used to stream content.

Increase the Default Upload Size

In IIS 8, the maximum upload size for files at the machine level is 30000000 bytes, which is around 28.6 MB. To enable uploading of files larger than this to MEDIAL, use the configuration editor to change two settings as explained in the following sections.

Change maxAllowedContentLength

2. Expand the requestLimits row and change the entry for maxAllowedContentLength from 30000000 to 2200000000 (eight zeros), which sets the size to just over 2GB.

3. On the right-hand side of the screen, click Apply to save the changes.

Modify maxRequestLength

1. Change the drop-down box at the top to system.web and click httpRuntime in the list.

2. Locate maxRequestLength and change the value to the size that you require. If you require 2GB, for example, enter 2097151.

Add Caption MIME Types

To add closed-captioning MIME types:

1. Open IIS Manager, click the server name on the left side, and choose MIME Types.

2. From the right-hand side, click Add…

3. In the dialog that opens, enter the extension .srt and the MIME type text/plain.

4. Repeat this process for the extension .vtt, also setting the MIME type as text/plain.
