[Laszlo-dev] [Gnash-dev] YouTube video via OpenLaszlo

[Don Hopkins]

I seem to recall something about the LZX compiler doing some kind of 
obfuscation on the byte code.
Maybe that's why the length of the arguments after an opcode is wrong?

Hi! I'm glad to help, and look forward to Gnash supporting Flash video!
I've checked the video stuff into the OpenLaszlo subversion tree at the 
following locations:

lps/components/extensions/av -- low level video components
lps/components/av -- high level video user interface components
demos/youtube -- youtube demo
demos/videolibrary -- video library demo  (requires Flash Media Server 
or Red5)
test/video -- various video tests

If you want to run the YouTube player in debug mode, to see if there are 
any warning messages in the debug window (and to see the mediastream 
status callbacks), then you can open it with this url:
