I installed the bz2 version and got: opera: Failed to set up core.

Thus I installed opera-12.14-1738.x86_64.rpm which is working. It has the same problem as v12.16.

The index page displays a correct Google map: http://www.nefkom.net/charlemagne/Opera.jpg the image page does not: http://www.nefkom.net/charlemagne/Opera1.jpg

See the hilfe link at the bottom for enabling the map:

1. enable display of descriptions
2. in the description line enable map by clicking on the symbol

I am reluctant to revert to version 12.14. An earlier trial to revert to an older version messed up the feeds database. Do you have any idea whether versions 12.14 and 12.16 are compatible with respect to the feeds data?

I got a photo album with some decent Google maps. Firefox displays them all but Opera does not:

Version 12.16

Build 1860

Plattform

Linux Betriebssystem x86_64, 3.11.10-7-desktop

Browser-Identifikation Opera/9.80 (X11; Linux x86_64) Presto/2.12.388 Version/12.16[/code]

Now I have installed opera-12.16-2.4.1.i586 and chromium-ffmpeg-33.0.1750.117-609.1.i586 After copying /usr/lib/chromium/libffmpegsumo.so to folder /usr/lib/opera/gstreamer/plugins/ Opera plays mp4 videos without any problems.

If no videos play, not even VP8 or Theora, something went wrong in replacing the file or modifying Opera executable.

I tried this page and Opera plays even all three videos at the same time without any flaw.

After verifying that Opera works well with some users, I turned back to the users were it didn't. Removing the .opera directory before starting Opera did not work. No videos were displayed when using a pristine configuration. By accident I discovered that invoking Opera once as 'opera -debuglibraries' changed things. After doing this all videos are now displayed, even when a new invocation is simply 'opera'.

Then I reinstalled my original .opera from backup and tried the same trick. It didn't work. After some trial and error I deleted operaprefs.ini and started again. Now the trick worked and everything is fine.

Performance is good when displaying the video in the original size. But when using full screen mode (1920x1080) Firefox is much better.

Anyway many thanks for your valuable tips. I would not have succeeded without them.

Many thanks for pointing to the chrome library! I got Opera to display the mp4-video for some users on the system, but for other users it does not work at all. Has anybody got an idea why this happens?

I installed Chromium and got the file /usr/lib/chromium/libffmpegsumo.so How can I tell Opera to use this file?

I got some videos which are played by Firefox, but not by Opera: http://karlmistelberger.jalbum.net/Bilder/2014/2014-01-06/p1010541.mp4 Any idea what to do?
