Flv-video (flash-video-stream) stream does not work under firefox 2.0.0.4. under a IDN-Domain from switzerland. (www.untergrund-blättle.ch) the punnycode is: www.xn--untergrund-blttle-2qb.ch

Unfortunately, the stream works under Internet Explorer 7.0 without problems.

Reproducible: Always

Steps to Reproduce:
1.site is loading
2.flash movie is loading
3.the flash media-player appears, but the stream does not start
4.i tried several different flv-players
Actual Results:  
the site appears normal, but the flv-stream does not begin

Expected Results:  
play the flash-movie

i'm not shure why firefox can not handle the flash-video-stream under a idn-domain. sound streaming works without problem...

Not a security sensitive bug.

If you turn off IDN in the prefs, or turn it off for just the .ch domain then it works.

If IDN is on then flash asks us to load: "http://www.untergrund-bl%C3%A4ttle.ch/moviez/shanty_town.flv"

which has %-encoded utf8 in the hostname. We currently don't unencode hostnames as an anti-spoofing measure (and there's old spec support for that), but more recent specs seem to say we should be unencoding there, too. That's bug 309671

This is probably simply a duplicate of that, but I'll mark it "depends on" for now.

Will this bug be fixed in firefox version 3.0? I downloaded the beta version and it is still the same problem. Flash stream is broken...

This should either go tto networking or Plugin/Flash.
Could we get Adobe to change the flash plugin ?

We should close this after Flash is EOL at the end of 2020.
