Annenberg Learner

13.2.0 is installed in a 1.5 here and I've found it fails to run movies in Annenberg Learner. The introductory page for the Mechanical Universe series is at http://www.learner.org/resources/series42.html . These movies worked in 12.1.0 or 11.3.0. With the fluendo decoder installed, mp3 audio works in Totem Movie player. gstreamer packages were just installed with this.

% sudo yum install -y gstreamer-{ffmpeg,plugins-{good,ugly,bad{,-free,-nonfree}}}

Still no improvement for the Annenberg Learner movies.

Can anyone identify the problem or suggest something to work on?

Not without fully checking every step of your process. Today I've tested 13.2.0 by added codecs and Adobe Flash and the video played fine, with well synchronised audio, in Browse, Epiphany or Firefox. The web site you refer encapsulates the video in Flash, so the installation of Adobe Flash is critical to success. The web site might not be compatible with Gnash. Speculation: you didn't follow the instructions, either neglecting the whole thing, the nspluginwrapper step, or the removal of gnash. This isn't a problem for deployments, since they create builds with these things already done. Therefore this isn't a bug. --Quozl 22:30, 15 November 2013 (UTC)

"Speculation: you didn't follow the instructions, ..."
Correct. I assumed Windows Media but, as you said, it's Flash. Installation of the Flash interpreter seems ok except for two details. For consistency with the other instructions "yum -y install nspluginwrapper ..." should be "sudo yum -y install nspluginwrapper ...".
To me, this suggested a problem:

nspluginwrapper: no appropriate viewer found for /usr/lib/mozilla/plugins/libflashplayer.so

libflashplayer.so is a shared object file? A binary executable shouldn't need a viewer.
Now when one of the Learner movies is opened the display process starts but then "Error loading media: File could not be played". The same in Gnome-Epiphany and in Sugar-Browse. The problem might be with the server or the communication but the result is identical about 12 hours later. Thanks for the help, ... Peasthope 05:51, 17 November 2013 (UTC)

The Adobe Flash installation for XO-1 and XO-1.5 section was incorrect because it missed the sudo prefix on two commands, and missed a chmod command. The XO-1.75 and XO-4 section was correct. The error no appropriate viewer was because of the missing sudo. This section been fixed. Give it another go. --Quozl 00:52, 18 November 2013 (UTC)
