How to display video file from database
I have successfully insert .wmv files into MySQL. When I display the video in the browser using Read.aspx to get the .wmv:
Response.ContentType = objDataReader.Item("swingContentType")
if I directly call this Read.aspx, window media will open and play the .wmv. But I want to play the .wmv in browser, so I use another file to display .wmv with <object>. Nothing happen:
<OBJECT id="player" type="application/x-oleobject" height="280" width="400" classid="CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95" VIEWASTEXT>
<PARAM NAME="Filename" VALUE="Read.aspx">

I found that it works if upgrade to windows media 9 and Acelp.Net Audio Codec is asked to installed.
From msdn web site, "Sipro Labs ACELP® .net audio codec is a version of the Algebraic-Code-Excited Linear Prediction (ACELP) compression methodologies that has been optimized for use on Internet Protocol (IP) networks and the Intel Pentium platform. Using the ACELP net-adapted packetization method, it is able to minimize the impact of errors and significantly improve the error correction possibilities in case of data-packet loss. This codec uses frame concatenation and interlacing to more efficiently encode data. In Windows Media Encoder, ACELP.net can be used to compress audio to bandwidths ranging from 5 Kbps to 16 Kbps. This codec is most useful for encoding low bit rate voice content.
After content has been sufficiently compressed, the data must be formatted so that it can be easily streamed over a network. To create Windows Media content for streaming, or downloading as a .wma file, the content is encoded in ASF."
Anyone know what happen. How can I fix it if users don't have window media 9?
