Hey everyone,
I've recently been experimenting with javascript and quicktime and have encountered a very frustrating issue with the quicktime plug-in.
What I'm looking to do is to be able to slow down a movie using setRate() without changing the pitch of the audio. Here is a mock-up of what I have so far:
http://www.theseare.net/work/video_mockup/video_mockup.html (Use the "1/2 Speed On/Off" button)
I initially tested this using Safari in Mac OS X. Using setRate() to slow the video to 1/2 speed worked fine and the pitch remained the same. Great. Unfortunately when I tested the page in Firefox the speed changed as well as the pitch! It seems that the QT pitch and speed controls are linked in Firefox. I tested the page in Safari, IE, and Firefox in Windows as well and experienced similar problems. The strange thing is, aside from it working correctly in OS X Safari, that in the standalone version of QT it works fine (for Mac and Windows). If you change the speed in the A/V controls the pitch is not affected.
So now the questions: Does anyone know why this is happening? Is there a way to independently control the pitch of a QT movie via javascript?
Any insight will be greatly appreciated. Thanks!
