803342 - HTMLMediaElement.canPlayType() says it can't play MP3 on B2G

Status: RESOLVED WONTFIX

(Core :: Audio/Video, defect)

Description

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

Testcase: http://pearce.org.nz/canplay.html

On B2G nsHTMLMediaElement::CanPlayType() is reporting that we can't play MP3 if we specify it as 'audio/mpeg; codecs="mp3"'. It's reporting that we can probably play AAC.

This means if we specify a "codecs" parameter in an <audio> element's <source>'s src attribute, we will refuse to play the mp3, though we can still play MP3 if the MP3 is specified in the audio element's src attribute. For example point your B2G browser at: http://pearce.org.nz/zurie.html

Oh oops, looks like audio/mpeg isn't supposed to take a "codecs" parameter.

Though Chrome's canPlayType() at least returns "maybe" for 'audio/mpeg; codecs="mp3"'.
