I'm using the latest version of Lion on my MacBook Air, all my applications are up to date. I've installed the following plugins; Flip4Mac, Java Applet, Quick time Plugin 7.7.1, Shockwave Flash, Silverlight Plugin, ClicktoPlugin, and Perian.
I'm trying to see a feed from a TrenNet IP Camera with Safari. The camera encodes in H.264, MPEG4 or JPG; I can only see the JPG feed on my MabBookAir. I can see the H.264 feed on my iPhone4s and I can see all of the feeds on my Windows 8 computer. When I doubleclick on the viewports for the H.264 and MPEG4 all I get is a very large frozen QuickTime logo.
I have the same situtation when trying to view H.264 and MPEG4 using Firefox
