Thank you for your help. I was half expecting this to be the answer. I have filed a corresponding bug with lightspark, and hope to get in touch with its developers.

Feel free to close this bug.

This is the key issue:
19360:2] 109 UNIMPLEMENTED: This SWF file requires AVM2: there will be no ActionScript interpretation

Gnash does not support ActionScript 3 bytecode
that generally used in flash file these days.

Gnash only supports ActionScript 2 and ActionScript 1.

I'm trying not to sound unhelpful but,
solution as far as I know, is implementing
entire ActionScript 3 interpreter stack and its class library,
which is a big, very big task indeed.

I heard that this has been tried before, but the attempt
falled apart due to lack of developer time (and funds).

Current workaround is to use Lightspark (http://lightspark.github.io/),
which features ActionScript 3 (and only ActionScript 3) runtime.

Note: AVM stands for 'ActionScript Virtual Machine'
AVM1 (which Gnash have) is used for running ActionScript 1 and ActionScript 2.
AVM2 (which Gnash didn't have) is used for running ActionScript 3.

The media9 LaTeX package contains a little flash program VPlayer.swf implementing a video player. This flash program will be embedded by LaTeX in the output pdf file. As a result, the pdf can contain movies, played by VPlayer.swf, if the pdf document viewer supports flash.

(see http://mirrors.ctan.org/macros/latex/contrib/media9/doc/media9.pdf for the details)

Unfortunately, this cannot currently be implemented in open source pdf viewers, because no free flash plugin correctly plays the VPlayer.swf file. In particular, I would expect to see a movie playing when I type

gnash -v -P "flashvars=source=random.m4" VPlayer.swf

with the test movie file random.m4 in the current directory. However, all I get to see is the player window. On the console there are a bunch of error messages which I append below. This is with Gnash 0.8.11dev (master-2-0a5e717) from Debian testing.
Any hint would be appreciated. In particular, I would be interested to know how much work it is to fix the bug/add the missing features.

Thanks
