Having the same problem on Jaunty, Firefox 3.0.13: The site example is: http://www.ceskatelevize.cz/ivysilani/209411000410829-predpoved-pocasi/
The mmsh hidden in the video is: mmsh://ctwm.visual.cz/iVysilani.Archive?id=MjA0OTY0NTk0fDYzMzg3MjU1NTQ5MTczMjMxMA==&SESSION_TO_MATCH=316b6e08441fea85ea75b36073a0b30b&MATERIAL_IDENTIFIER=209411000410829&CONTENT_NAME=1178166999&TITLE=predpoved-pocasi&GENRE=zpravodajske&LIVE=0&MSWMExt=.asf What I tried: Installing: gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-multiverse gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse gstreamer0.10-ffmpeg gstreamer0.10-pitfdll w32codecs (and others) mplayer was already present Adding: vlc player gxine player totem Now, if I copy mmsh code from site and put in VLCPlayer, it plays it nicely and instantly (play > network > mmsh: ...). If I copy it to MPLayer, no way to be played (just first frame is sometimes shown). But it doesn't play it in Mozilla (instantly). I try to change preferences in mozilla for .asf files (I suppose it is correct, as file ends with .asf): default setting is Windows Media Player Plugin 10, I cannot change it to the other options as seen down in the list regarding the other extensions (nothing else is in right click menu) so I manually enter: /usr/bin/xine or /usr/bin/vlc (I hope this was not wrong step) - but no change. As you can see in the screenshot, if I check "What is this" on video, it still uses Totem, whatever I tried to set in preferences. (???) One final update. After 10 minutes with setting of /usr/bin/vlc, video suddenly started to play. But that is too late... my connection is ok, as you can see with VLCPlayer out of Mozilla. I see many similar bugs, that deal more or less with the codes, but not satisfyingly solved: https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/392578 https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/239295 https://bugs.launchpad.net/ubuntu/+source/libmms/+bug/284821 https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/237474 https://answers.launchpad.net/ubuntu/+question/47790 https://bugs.launchpad.net/ubuntu/+source/gstreamer0.10/+bug/46217 https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/192888 https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/201770 ** Attachment added: "Screenshot in Mozilla" http://launchpadlibrarian.net/31018870/Firefox%20What%20player.png -- Firefox will not play MMSH protocol videos. https://bugs.launchpad.net/bugs/392578 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
