It's funny this should come up - I'm actually attempting to write a
Mozilla plugin using avifile, right now. At this stage I'm just using
the sample libnullplugin that's provided with Mozilla, and shoving the
following code in the "NPP_New" function:
#define FILE "mms://media4.abc.net.au/triplej"
avm::IAviPlayer *player; player = avm:: CreateAviPlayer (FILE,0,0,0); while
(!player->IsOpened()) { sleep(1); }
player->Start();
while (1) {
player->Play();
sleep(1);
}
Now, this code works fine when put in it's own little standalone
program, but when run as a mozilla plugin, I get warnings that it can't
open the codec libraries:
<ASF reader> : Codec Type: Audio

I thought maybe that it was because avifile uses dlopen on the various
codecs it needs, but when I tried my own sample code that does a dlopen
on libm.so, it works fine.
Is there Anyone out there familiar enough with both avifile and plugins for
mozilla willing to hazard a guess on what I'm doing wrong?
I've compiled the plugin with:
gcc -shared -o aviplugin.so npunix.o npshell.o -laviplay
...which I assume is the correct way to do it.

Yeah, I tend to agree. Unfortunately there's veritable sh*tloads of
webpages out there that seem to expect the user to have some sort of
plugin for various streams.
I've tried Codeweaver's plugin, and although it works really nicely for
quicktime, I don't much like using it for WMA streams - so I figured I'd
write my own.
Cheers,
Paul
