User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9b5) Gecko/2008043010 Fedora/3.0-0.60.beta5.fc9 Firefox/3.0b5

Description of problem:
Some Flash video streams don't work with Adobe's Flash plugin wrapped on a x86_64 system, but work wrapped on a i686 system. The Flash player doesn't crash. It just doesn't play the video.

An example: http://www.tagesschau.de/multimedia/sendung/ts4932.html

I tried to capture the network traffic with Wireshark. Please take a look at the attachments. After the Flash player is loaded on the i686 system, it sends a DNS request for the streaming server. This isn't the case on the x86_64 system. Something seems to prevent the flash plugin from doing some network activities. I suspect nspluginwrapper. But I don't know how to debug further.

Things like YouTube work without a problem.

Version-Release number of selected component (if applicable):
nspluginwrapper-0.9.91.5-27.fc9

How reproducible:
Always


Steps to Reproduce:
1. Go to the mentioned URL
2. Start the video
3. Look what (not) happens

Actual Results:
On a x86_64 the video doesn't play, but it does on a i686 system.

Expected Results:
The video should play on a x86_64 system too!

Comment 3 Torsten Rausche 2008-06-12 07:47:43 UTC 
This can be fixed by installing the package nss-mdns.i386

I guess this dependency should be in flash-plugin.i386. So there is not much we
can do.
Comment 4 Torsten Rausche 2008-06-12 09:03:22 UTC 
Another note: this only happens if nss-mdns.x86_64 is installed. It's not clear
to me which component is to blame. It could be everything from flash-plugin to
glibc/nscd. Perhaps it could even be considered as NOTABUG.
