5412	"Add ""Accept-Ranges: bytes"" response header and support for videos"	Mike Swierczek		"For streaming large (greater than 1GB) WebM videos, support for the ""Accept-Ranges: bytes"" header indicates to the browser that partial content requests are supported.  This allows the viewer to jump around the video without having to wait for the whole video to load.

To see this in action, take a large (greater than 1 GB) WebM file and load it onto Mediagoblin, and then try to watch it from the middle.  Use the download link to open the video in its own browser tab, and try to watch it in the middle.  Again, it will hang for a long time as the data buffers.  If you use browser tools to examine the request, the request will have one HTTP 200 response.

Host the same video on nginx and watch it through the browser.  You will be able to jump around the content as you like.  If you examine the network traffic, there will be an HTTP 200 response for the first request and then HTTP 206 Partial Content responses for each click to navigate.

I'm going to try to figure this out myself, but Python isn't my normal playground.  A Mediagoblin developer will probably be much faster."	enhancement	closed	minor		programming	invalid
