Encoding mp4 for Windows Phone
 

I have a mix of sponsor hosted videos and videos encoded by myself on a site. I'm updating the site to make it mobile friendly and so have starting converting the old flv's to mp4.

I note that the ones I've encoded myself using Handbrake will preuso-stream on a PC, and on Android, but will not pseudo-stream on Windows Phone. It downloads the whole file before playing it. On the other hand, some sponsor video mp4s that I've added recently do pseudo-stream on all the platforms.

What am I doing wrong - I'm using the web optimise option in Handbrake and the iphone & ipod touch profile as that's what these guys recommend. Or is it that Handbrake can't do this and I need something else?

Maybe it's that my server is not set up to give WP the info it needs to stream....need to do a little test.

Ok, looks like it is my server configuration, but seeing as I'm about to move to a new one I'll leave as is for now. Nothing to do with Handbrake.

As you were.

Nothing to do with your server conf.
Enable "Web Optimized". This gives you what you wants.

I'm already using that. You didn't read my first post.

I did a test with a mp4 from a sponsor.

On their server, on Android = works.
On my server, on Android = works.

On their server, on Windows Phone = works.
On my server, on Windows Phone = doesn't work.

There is some info that WP asks for before it can stream the movie or seek beyond the buffer, I'll have to google it again to be sure what it is.

Maybe it is missing a mimetype in your Apache conf or .htaccess (assume you are using Apache):
AddType video/mp4 .mp4
