You’ll be serving your customers from a CDN node that’s best for them (UK guys get served from the UK node, US guys from the US node etc) which will give better performance. I don’t know that much about video file formats, but I did find this blog post by Renaun Erickson which describes a problem with H.264 files where the index for the file (which allows streaming) is placed at the end of the file, meaning you can’t start streaming until you’ve downloaded the whole video! He’s created a small tool, the QTIndexSwapper, which moves this index to the beginning of the file, which you can download from that page as well (requires Adobe Air).ĭoing this on my videos made an instant difference for Media Player – which now started streaming the videos correctly.
For instance, Google Chrome consistently streamed my MP4s without me needing to make any changes, but Windows Media Player (and anything that relied on it, such as embedded video streams) refused to. It seems to make a difference how you choose to play them as to what’s needed and what’s not. If you’ve got this far (and I got this far) then it might be time to examine your videos, to make sure they’re in the best possible shape to support streaming downloads.

This enables Microsoft to make changes to the infrastructure without breaking everyone’s code each time they change how a feature works. When it was created, your account was assigned a specific version number, and it will run at that version number until it’s changed. It’s also in a state of evolution, with new features being added all the time. Instead, it’s a purpose-built system, designed to deliver content in the most efficient way possible. Because it has some pretty specific and unusual requirements, Microsoft don’t run it over IIS. You should change this to be correct for your media. By default your videos may well have the type application/octet-stream. Make sure you have a sensible value in the Content-Type header.
