I see lots of articles claiming that Flash Player 9 can play
MPEG-4 video, but I have yet to get this to work. The standalone
Flash Player does not recognise anything but .swf files, and will
not play H.264-encoded .mp4, .mov or .flv files. The Flash plugin
only supports application/x-shockwave-flash and .mp4 and .mov files
are handled by QuickTime. Adobe Media Player happily plays H.264
files, but this is not the same as Flash Player, is it?
I am running OS X 10.5.2 on an Intel Mac, if it makes a
When Adobe and everyone else state that flashPlayer9 can play
.mp4 and .mov they mean the runtime, not the stand-alone player.
The stand-alone player is intended, as you have discovered, to play
.swf files. Using the Flash Authoring tool you can create a SWF
video-player that can play .mp4 and .mov files as long as you
publish to flashPlayer9. The Adobe Media Player is a program built
in AIR, which is a runtime that utilizes the flashPlayer runtime,
and therefore is able to play .mp4 and .mov files.
