H.264 Streamed Video works in Chrome 23 but not Chrome 24, different request headers ... same cherry backend
On the site I'm currently working on, we are using html5 video with h.264. If it is not available, we use flash reserve. The flash fires fine in both chrome 23 and 24, but html5 video only works in chrome 23.
I opened the video file in my own tab (in which chrome then has a simple chrome bootable html file snippet to play) in each chrome version and saved the request and response information. There are actually three queries, but I find the first one to be the most interesting. Here is the header information for request and response for both.
Chrome 23:

Has anyone else expanded on this? I would also like to conduct further testing upon request.

You can fix this problem by following these steps: There is an option in chrome: // flags called "Disable hardware accelerated video decoding".
And this is a bug filed three weeks ago: http://src.chromium.org/viewvc/chrome?view=rev&revision=178906 . According to his status, he is "corrected". However, later in the comments it says that the fix can be ported to the M25 version and fixed with the 26.0.1395.1 version.
As a test, I downloaded version 26 of Chrome (developer version), (re) disabled "Disable hardware video decode acceleration" and everything works fine. If you'd like to do the same, visit the Chromes release page and select the Windows Dev Channel.
