I’m streaming videos from my Wowza server which are encoded at 1000kbps. However, streaming them to a web page with JW Player, the video is taking up as much as 16000kbps and a minimum of 5000kbps while streaming. Our users are experiencing performance issues because of bandwidth limitations and I’m curious as to why it is so high. ---

Are you sure you are streaming one of the encoded streams? It sounds like you are streaming the source Richard ---

Sorry, I got the (wrong) impression you were using the Transcoder… anyway, the calculation seems right. (174 \* 8 / duration). Where are you getting this report of 5000kbs to 16000kbs? The Wowza Silverlight example will display bitrate of single stream. Richard ---

Probably you have configured your player to download the files from your webserver via progressive download rather than being streamed by Wowza. ---

There appears to be some confusion in that plugin page, mentioning two “widths”: 720 pixels, and 480px. Usually we reference height: 480p, 720p, etc… ---

JW Player quality monitor’s bandwdth display is the players perceived available networking capacity - NOT the incoming bitrate of the stream ---

We are streaming files, but (for example) one of the files is 1134 seconds (just over 19 minutes) and has a filesize of 174 MB. This should work out to 1228 kbps. Is there another file I should be streaming? ---

I’m using two things: a) JW Player has a quality monitor: [http://www.longtailvideo.com/support/addons/quality-monitor/14627/quality-monitor-plugin-users-guide](http://www.longtailvideo.com/support/addons/quality-monitor/14627/quality-monitor-plugin-users-guide) b) I thought these numbers were really high, so I installed a windows network meter widget. [http://i274.photobucket.com/albums/jj250/psizovrak280/networkmeter-1.png](http://i274.photobucket.com/albums/jj250/psizovrak280/networkmeter-1.png) The current largest spikes on that meter hit about 15Mbps. This may be because I’m testing on a wireless connection, but the overall datarate is about consistent with that of the JW Player’s quality monitor. EDIT: I’ll also note that we’re encoding to mp4/mov files.
