Distortion of full-screen iplayer video in Ubuntu Firefox

Asked by Stefank

After a fresh installation on 8th May of 12.04 LTS and Windows 7 (previously 10.04 LTS and Windows 7) in separate partitions, iplayer in Firefox distorted in each OS by breaking up into seperate horizontal segments in full-screen mode. Previously this did not happen in either operating system. Screenshots cannot show this because the blurring disappears on pause.
This new problem was fixed in Windows 7 by installing the Adobe Flash plugin when prompted by Firefox, but the problem persists with 12.04 LTS and did not happen with 10.04 LTS.
I have activated the Nvidia acceleration, installed all updates from Software Updater and checked my Shockwave Flash and Totem plugins are up to date on the Firefox website; my mozilla plugin fle contains:
/usr/lib/mozilla/plugins/flashplugin-alternative.so
/usr/lib/mozilla/plugins/libflashplayer.so
/usr/lib/mozilla/plugins/librhythmbox-itms-detection-plugin.so
/usr/lib/mozilla/plugins/libtotem-cone-plugin.so
/usr/lib/mozilla/plugins/libtotem-gmp-plugin.so
/usr/lib/mozilla/plugins/libtotem-mully-plugin.so
/usr/lib/mozilla/plugins/libtotem-narrowspace-plugin.so
There is no blurring if I play a video full-screen on You Tube, even in HD, so this blurring seems to be specific to streaming IPlayer in Firefox on Ubuntu 12.04..

Enable the partner repo if you haven't already then install the adobe-flashplugin package. You will get 64bit flash. Close all browsers and rerun the browser to load the new plugin

Unfortunately the problem remains after restarting the computer, getting a message from Software Update that there are no updates available ("Other Software- Canonical Partners" previously ticked) and then opening Firefoxr.

Synaptic changelog tells me that I have downloaded the right thing:
flashplugin-nonfree (11.2.202.280ubuntu0.12.04.1) precise-security; urgency=low

  * New upstream release 11.2.202.280
    - debian/flashplugin-installer.{config,postinst},
      debian/post-download-hook: Updated version and sha256sum.

uninstall flashplugin-nonfree and install adobe-flashplugin

flashplugin-nonfree was not installed.
I installed adobe-flashplugin using Synaptic, which also installed adobe-flash-properties-gtk and removed flash-plugin-installer.
The problem is now slightly worse despite a reboot.

The plugins folder now has:

/usr/lib/mozilla/plugins/flashplugin-alternative.so
/usr/lib/mozilla/plugins/libflashplayer.so
/usr/lib/mozilla/plugins/librhythmbox-itms-detection-plugin.so
/usr/lib/mozilla/plugins/libtotem-cone-plugin.so
/usr/lib/mozilla/plugins/libtotem-gmp-plugin.so
/usr/lib/mozilla/plugins/libtotem-mully-plugin.so
/usr/lib/mozilla/plugins/libtotem-narrowspace-plugin.so

Have you tried Chrome?

Stefank (stefankarpik) said : 		#8

It's no better in Chromium, I'm afraid

Chrome isnt Chromium

Dear Andrew,

Thanks so much. There is still some small blurring occasionally in Chrome, but this is perfectly acceptable.
Cheers,
Stefan

Adobe are ceasing support for Flash in the future so Chrome will be the only way to get Flash in Linux as it uses its own Pepper Flash. I believe that it can be symlinked to be used by other browsers too. Omgubuntu has a guide or two

Hi Andrew. Yes, you're right - Adobe will stop to support Flash Player 11.2 for Linux with security updates, but it will happen in 2017! I think, that till this year, projects such as Gnash or LightSpark will evolved in such a way, that we could replace Flash from Adobe with one of them.

Best regards.
