1214441 - h265files WebM sample doesn't play in Firefox

Status: RESOLVED INVALID

(Core :: Audio/Video: Playback, defect)

Description

[Chris Pearce [:cpearce (Not reading bugmail)]]

The WebM VP8 sample at http://www.h265files.com/embed-h265-video.php doesn't play in Firefox. It plays in Chrome. Also we're returning not even trying to load it, implying our canPlayType is broken.

I tested in 42b5 on Win10;
Mozilla/5.0 (Windows NT 6.3; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0

41 Release also has this behaviour.

This file is a webm with a VP8 video track, and AAC audio track ; not vorbis as the mimetype indicates.

From: http://www.webmproject.org/about/faq/

"VP8/VP9 video and Vorbis/Opus audio are the only codecs allowed in a valid .webm file. Why did you define WebM so narrowly?

We decided to define WebM files in this way because we wanted to do what's best for users. Users just want video to work, they don't want to worry about supported codecs, file formats, and so on. After much discussion with browser makers, tool developers and others, we reached a consensus that a narrowly defined format would cause the least confusion for users. If a user has a .webm file, he or she can be confident that it will play in any browser or media player that supports WebM."

having an AAC track in a webm is invalid
