My Flash Video Replacer experiences problems on detecting videos in mp4 format and can't play them. Apart from videos, there are also many websites like Busuu where I encounter Flash animation problems. What can I do to overcome this?

P.S: I use Trisquel Taranis and Web Browser 3.6.22.

In the preferences of FlashVideoReplacer ("Sites" tab), you can uncheck a site so that the extension does not handle it. Gnash will. If you are talking about YouTube, you can also add "&html5=1" (without the quotes) at the end of the URL and let the Web browser handle the video (instead of the Gnash). This browser must be recent enough though. Trisquel's default browser (until Slaine), based on Firefox 3.*, is not. You can install and use IceCat 5.0 as a more recent alternative. It is in Trisquel's repositories.

As I've said, contrary to many of the problems that I've read on the forum, my problem is more general than site-specific so I guess the first thing that I'll try would be just disactivating FlashVideoReplacer and let Gnash handle Adobe Flash files instead. Eventually, I may have to consider to uninstall Web Browser and Midori and install IceCat instead :/

By the way, I once read somewhere that there is a possibility to change rpm packages into deb on Trisquel? Is this really possible?

The 'alien' command does that: http://kitenet.net/~joey/code/alien/
It is in Trisquel's repositories.

However, read and reread the warning on the site of the command:
Despite the large version number, alien is still (and will probably always be) rather experimental software. It has been used by many people for many years, but there are still many bugs and limitations.

Alien should not be used to replace important system packages, like sysvinit, shared libraries, or other things that are essential for the functioning of your system. Many of these packages are set up differently by Debian and Red Hat, and packages from the different distributions cannot be used interchangably. In general, if you can't uninstall the package without breaking your system, don't try to replace it with an alien version.

After reading the warning on their page, I'm sure I won't abuse it. I don't think I'm able to go to the extent they're referring anyway :P So I downloaded alien with all the additional necessary software but it doesn't figure anywhere on my system; therefore I can't see any help index to teach myself how to use it :(

'Alien' is a command to run in a terminal. You can access its manual as usual:
$ man alien

Thank you. I managed to find the help file within the command and found my way from there.

Since Gnash or another alternative to flash, is just an alternative to a closed and discouraged format, it will be always hard to implement an up-to-date solution and the solutions probably will be always site-specific.

I don't believe that FVR avoid you a correct behavoir from Gnash. AFAIK, it will always work with only videos and from very specific sites.

I'm using abrowser and icecat without problems. Also, it is not recomendable to remove pre-installed software (as abrowser) of the distro, apt can be confused and it's possible it want to uninstall almost every important package.

I believe you are talking about trisquel-recommended, trisquel-desktop-common-recommended, trisquel-gnome-base-recommended, etc. They are not "important packages". They only define the default system. In other words, each of these packages depends on a list of applications in the default install but, by itself, does not install anything. Removing them has no consequence beyond the ability to discover new software that Trisquel's developers would have decided, "a posteriori", to include in the default. It is very rare but has actually happened with flashvideoreplacer (trisquel-gnome-base-recommended depends on it).

I know that Busuu has been working with Gnash (installed by default) except:

* The language garden (but it is only for recreational purposes)

* In vocabulary, firstly you don't see the first image and title, but if you click the right arrow you will see the second ones, and then you can click the left arrow and see the first photo and the title. However, sound appears not work in that section.

* In review, you can hear the sounds if you manually click the symbol on the right of the title.

I hope it helps you.

Well I guess in that case whenever I want to study on Busuu I'll have to revert back to Windows since these are not durable solutions for me. Then again, I'd heard that through Wine or Virtualbox I can run a Windows system on my Taranis. Can somebody inform me how that is possible as to having the OS on Linux and say running Google Chrome?

Besides, as I've tried to explain the only problem with Adobe Flash is not on static video pages but also when I want to watch a streaming video or view certain animations on pages ;(

The operating system you use is GNU/Linux. Linux only is its kernel: https://www.gnu.org/gnu/why-gnu-linux.html

In this forum, nobody will help you to install proprietary software. Anyway, notice that installing the Adobe Flash plugin in Trisquel makes one (very ugly) piece of proprietary software on your system. Using Windows looks far worse...

I'm sorry that some times free software solutions are not as good in quality as we'd like, it's really a shame. However, maybe we can use theese times for analysing which is the problem in the backgroud. Normally, as in this case, the problem is an undesirable technology which owner want to dominate the world(-wide-web), expecting everyone uses it software while they don't advice this fact.

However, free software comunity has the responsability of advicing this fact and discouraging the use of that kind of technologies. So, we cannot help you to go a step backward in your freedom offering you help for setting privative software (both Windows and Chrome are), instead of that, we'll help you to find the available alternatives and encouraging you to be activist, spreading the word of the bad things that flash carries.

But in the end, your elections will be always yours, our only mission is show you the doors, isn't angry you. :)

Have a good time

No worries. If I didn't prefer completely free software I wouldn't choose Trisquel and go for Ubuntu anyway. The reason why I asked about Virtualbox or Wine was the fact that in any case I'd need to learn it to be able to play my games who run solely on Windows and I figured that I might use that also as a viable solution for the problems I'm experiencing with swf files and so on until Gnash/FlashVideoReplacer or any kind of other software solves that problem with an update. Sorry if I didn't express my intentions well enough :)

Otherwise, as I've said, I know very well that if I want to use proprietary software, I should have just install Ubuntu or Mint ;)

By the way, can I install Icecat and uninstall Web Browser than without encountering problems further down the line? Also, I have a Firefox extension called Xmarks and I'm wondering why it isn't also in Web Browser's extension list :/ It is a free service as far as I know...

Xmarks is free (gratis) but not free as in freedom. If you check their license (https://addons.mozilla.org/en-US/firefox/addon/xmarks-sync/license/4.0.2) it is not a free software license.

Thank you for your reply! I suspected that the problem should be in regard to their license anyway :/ In that case: Does anybody on the forum have an alternative to the service provided by Xmarks so I can move onto that definitely? It would especially be nice if that would be a service that I can use on Epiphany ;)

If you move to a recent version of IceCat (such as the one in Trisquel's repository), Firefox Sync is integrated. It provides the same features as Xmarks but is Free software and your data are locally encrypted before being sent to the server (no privacy issue). In fact, you can even setup your own server if you really do not want to trust Mozilla (but, well, if you trust a proprietary add-on for synchronization, that would be strange you see a need to not use Mozilla's server).

If you stick to Trisquel's default browser (until Slaine), you can install the package xul-ext-sync, which is in Trisquel's repository (hence Free software) too.

I tried to find xul-ext-sync on Trisquel's repository but it wasn't there so I guess the only viable solution for me in that case would be to upgrade to Icecat? :(

Indeed, xul-ext-sync only is in the repository of Trisquel 4.5 Slaine and you use Trisquel 4.0 Taranis: http://packages.trisquel.info/search?section=all&keywords=xul-ext-sync

Since the download page for xul-ext-sync strongly suggests using the embedded option like Synaptic to install/uninstall any software, I guess I'd pass on this option even though I'm seriously excited on a new alternative and rather try IceCat out this time. Yet since that proposal also came from you big thanks in any case Mr Banana ;)

You can install IceCat 5 from the repository. When it comes to removing ABrowser, it can look a bit more intimidating. It should not. Just reread my message above: https://trisquel.info/fr/forum/another-adobe-flash-problem#comment-12543

I tried IceCat, but the code is behind the actual Firefox releases. Firefox is at 6.02 right now and IceCat was stuck at 5 and only recently updated to 6.01 via the https://launchpad.net/~gnuzilla-team/+archive/ppa PPA. The Trisquel repositories are still at 5. This is a serious problem especially on the Firefox rapid release cycle and important security issues only get patched in new releases. The DigiNotar SSL certificate vulnerability comes to mind.

I took a look at http://packages.trisquel.info/search?keywords=firefox and noticed that Firefox "is" part of the Trisquel packages (even if not updated) so I simply did a sudo add-apt-repository ppa:mozillateam/firefox-stable for releases pre-Dagda.

I noticed that Dagda, based off of 11.04, has "abrowser" which is Firefox anyways just without the branding. Canonical has been keeping up to date with Firefox as of 11.04 (Dagda) and onwards so you either have to rely on the Trisquel team keeping "abrowser" up to date or simply add the official natty repositories in your sources.list.

That is not true. The latest version of GNU IceCat is 6.02, released at
8th of September. [1] AFAIK just version 5 is packaged for Trisquel.
There is an official GNUzilla Team PPA [2] where deb packaged are
provided. The latest build is for version 6.01. I think you will have to
match the Ubuntu version on which your installed version of Trisquel is
based, when adding the PPA repository.

I personally test the latest versions by compiling and installing them
in /usr/local via GNU stow:

$ sudo aptitude install stow
$ cd ~/src/icecat-6.02
$ ./configure
$ make
$ sudo mkdir /usr/local/stow/icecat-6.02
$ sudo DESTDIR=/usr/local/stow/icecat-6.02 make install
$ cd /usr/local/stow
$ sudo stow icecat-6.02
$ whereis icecat
icecat: /usr/bin/icecat /usr/lib/icecat /usr/lib64/icecat /usr/local/bin/icecat

The binary for version 6.02 is /usr/local/bin/icecat. The 5th version
binary provided by Trisquel is /usr/bin/icecat.
You will have to run 6.02 with it's full path : /usr/local/bin/icecat.
It will take some time to build it, if you have all dependencies.

To uninstall the installed version in stow:

$ cd /usr/local/stow
$ sudo stow -D icecat-6.02
$ whereis icecat
icecat: /usr/bin/icecat /usr/lib/icecat /usr/lib64/icecat

Now you can install a different version that is compiled locally.
Good luck!

Sorry, I forgot two crucial steps.

$ sudo mv icecat-6.02/usr/local/* icecat-6.02/
$ sudo rm -rf icecat-6.02/usr
