How can I track the amount of bandwidth used on a streaming video? For progressive download of video, we can say the user downloaded X number of bytes. However, if the video is streaming, there's no way for me to say X number of bytes have been downloaded/transfered/whatevered - at least not that I can find. Anyone have any ideas?
Secondly, on progressive download, how do you "kill" the download process? I want the download to stop downloading if the user navigates away from the video. I've yet to find any way to stop the progressive download process...
