Bug 86308 – <video> won't load when URL ends with .php

• Component: Media
• Status: RESOLVED FIXED

[Eric Carlson]

A media file that does not provide MIME a type in the markup, eg. does not use <source type=...>, will not load if the url has a non-media file extension for which MIMETypeRegistry::getMediaMIMETypeForExtension() returns a type. This is caused by the changes in http://trac.webkit.org/changeset/102800 in many cases because we now correctly extract the file extension from query urls.

This variable name sounds like it would be a type, not a boolean. m_typeWasInferredFromExtension should like a boolean. Or for additional clarity, m_contentMIMETypeWasInferredFromExtension.

Seems strange that for m_url, m_contentMIMEType, and m_contentTypeCodecs we use local variables and set the data member only at the end, but for m_typeInferredFromExtension we set the data member directly. The code would be easier to read if all worked the same way.

Seems like for clarity mediaType could be named inferredType.

Excellent point, but I forgot to fix this before checking it in. I will clean this up the next time I modify this file.
