Not at all.  I would expect they'd deliver something very akin to the AV 
revamp of the player object, just for all platforms and written using LCB.

But even with LCB, making all those features is a bit of work.

Since right now we Linux folk have no media support at all (and haven't 
for a long time) I'd be very happy with something less ambitious.

And I'd imagine the net savings for putting in a small number of 
commands in C++ would still be significant over designing and writing 
much more code in LCB.

Kevin may have other plans I'm not aware of, but on the surface LGPL 
would seem a good fit for both proprietary and GPL use.

I would imagine that if Fraser were unleashed on that API for a couple 
days then LiveCode's multimedia support on Linux might exceed anything 
it's ever had before on any platform. :)

But I'd be thrilled enough if it just had startTime.

Oh, and the ability to play a movie without crashing. :)

The situation with codecs is well understood in the Linux community.  At 
most RunRev's expense is a caveat in the Dictionary entry for related 
commands, as they do now for things like Oracle drivers which have 
special restrictions.

This only seems hard to those who don't use Linux.  But really, I work 
with that community daily; very different set of expections about things 
like codec licensing.

Crashing, on the other hand, is not enjoyed by users of any platform. ;)


Besides, RunRev has already decided to support media playback on Linux. 
The only new question I'm raising here is whether it needs to wait for 
The Ultimate Widget, or could we please have a few lines of C++ to tide 
us over for the next year or so.
