Well, the browser specification says: 'Macromedia Flash 7.0 compatibility' and the browser plays files created with Macromedia Flash Professional as 'Flash 7'. Does this prove that it's not Flash Lite? Hmm. How can I check child/root issue? And this still doesn't explain all the messages like: ming: 'Stream out of sync... 155 but expecting 151' gnash -v: 'ERROR: swf_event::read(), event_length = 84, but read 83' It is my guess that openlaszlo swf doesn't follow flash specification very tight and 'official' flash player can work it around, but others can't.

The OL > nightly builds are getting closer! The most I've seen till now is that canvas bgcolor is displayed correctly. Also, please note that gnash and libswfdec have exactly the same problem: they display only empty picture with correct canvas bgcolor. Do you have a build that can show more that this? My gnash is 0.7.2 The problems with libswfdec leads to very funny bug later with gnome under linux, see https://launchpad.net/bugs/85343 note that swf file in question is laszlo-generated. > (One quibble with your characterization: if a swf plays on the > Flash player and does not play on a Flash emulator, is the bug with > the swf or the emulator?) There may be a bug in the emulator, but all emulators I see around refuse to play same simple file created with OpenLaszlo for some reason. This makes me think that this is a bug in swf file after all. Or all of them. Given all the facts I have it easier to suspect the bug in one swf file that many (same or different) bugs in many different flash emulators. Best regards, Alexey.
