Please advice how to install libx264 codecs, it is required to make openshot video editor functionality full. I've tried to execute
Code:
sudo apt-get install ubuntu-restricted-extras
but some dependences got wrong after. Than i have tried to execute
Code:
sudo apt-get -f install
and begin to execute this but it has been done with error also. After i could not start some of media applications installed on the hard at all and had to re-install Navigatrix.
But may be the reason was in that i've ticked all repositories in "Other sofware" of Package Manager and made update prior above mentioned action and it infringe some dependences? Now just would not want to re-insatll system again cause it is too much for my hard last time, may be there are some one evident way?
Thanks in advance.

The x264 video coding library (libx264-85) is already installed in Navigatrix.

I installed "ubuntu-restriced-extras" but the installer wants to overwrite a file that one of ubuntu-restricted-extras dependencies has just created three seconds before. It's not supplied with the instruction to do this ...so it gives an error.

You need to install libavcodec52 which has the proper instructions. This will then allow ubuntu-restricted-extras to finish installation.

I'm not sure what has happened by ticking the "other" software sources...maybe that's not a good idea.

Exactly, after all it was done, the problem was with libavcodec52. Terminal reported about wrong dependences of libavcodec52.
Should i execute
Code:
sudo apt-get remove libavcodec52
to remove it first? Is it correct command?

This might be a result of the "other" software source...OR a blanket upgrade. Blanket upgrades paint more people into corners and break more things in complex systems than any other factor. Un-tick the ones you had previously selected; reload (update) and see if you are given another chance.

You can use sudo apt-get remove <package> or
sudo apt-get purge <package>

Purge is a little more definitive. It removes the package and any trace of the package (...not completely true. Sometimes remove or purge will leave menu entries, empty directories, directories where you've added data in the form of personal configuration files...etc.) But it's not a perfect world.

Code:
sudo apt-get remove libavcodec52
and than install
Code:
sudo apt-get install ubuntu-restricted-extras

Am i correct?

Because in may case Openshot reports about missing of libx264 codec when i try to render piece in specific format for example mpeg4, taking in mind that libavcodec52 installed on the hard. Thus i conclude that may be libavcodec52 is not suited for Openshot.
I installed Openshot with
Code:
sudo add-apt-repository ppa:jonoomph/openshot-edge
sudo apt-get update
sudo apt-get install openshot openshot-doc

and had no problem with installation.
May be the problem is in that said above in terminal:

So, it was easy. I've just install libavcodec-extra-52 and OSh started ok! Therefore i replaced libavcodec52 prior - it is decision.
But as a result all media application as Openshot, Video Player and Web Cam app became dead (not started at all) and i had to re-install it. Also wxcam refuse to be installed evidentially conflicting with new dependencies, i have installed cheese instead
Code:
sudo apt-get cheese

Cheese works ok.

No, sorry...sometimes I don't remember what I've done on my own machine.

Upgrading and still having flexibility is very difficult. It's like assembling a very complex puzzle. It's really easy until it all goes wrong.

Because of the nature of some of the software packages they should be labelled with health warnings "Use of this software can lead to chemical dependency, premature ageing, psychological trauma, even abject resignation. Proceed at your own risk."

For example, you upgrade to the swanky new library lib2cool...latest version 2.65.4...whatever. It's a fake name, but you're upgrading from 2.4 to 2.65.4

One of your favourite applications uses lib2cool. It lists lib2cool as a dependency; but lib2cool is not a dependency of your favourite application. (E.g., my sails need wind, but the wind blows regardless of my sails.) But now this favourite application is a little unstable, or it just doesn't work. The logical step is to upgrade it.

It doesn't upgrade. Pulling your hair out you find it requires lib2cool that is at least version 2.5. ...this is where you start drinking.

Both you and I know that version 2.65.4 is 'newer' than version 2.5. But this favourite application doesn't. In the computer's little pea-sized brain it 'knows' 2.65.4 is not 2.5 and it wants...it needs 2.5. The update you're trying to install was written before lib2cool 2.65.4 was even released. It's not going to budge.

...so you resolve to downgrade to lib2cool 2.5 which was skipped over in the upgrade process.

When you try to downgrade lib2cool all hell breaks loose. Sure you can remove it but the package management system informs you there are 83 other applications, other libraries, core systems that will not work and will be removed as well.

If you try to downgrade you 'pith' your system; remove it you pith it...leave it in it's just crippled.

This is the point you drink straight from the bottle and don't bother putting the cap back on.

Not every upgrade goes wrong. However, when the prime reason for upgrading (anything in the universe, not just software) is "it's new"....there is a greater chance you will loose functionality, freedom, or money. Since Navigatrix is free open source (mostly) software that pretty much just leaves functionality at risk.

On the test I ran I had the default repositories and reloaded (sudo apt-get update

sudo apt-get install ubuntu-restricted-extras

It failed.

Really? I thought to myself and ran the command again.

sudo apt-get install ubuntu-restricted-extras

Same thing.

I ran sudo apt-get install libavcodec52

It installed and stated it was attempting to recover from a previous failure. It stated it completed without error.

Really? I ran the command again.

sudo apt-get install ubuntu-restricted-extras

It was already installed...along with the other 40+ packages that are its dependencies.

If you're failing in this attempt; go back two steps. Remove libavcodec52 and ubuntu-restricted-extras and try ubuntu-restricted-extras first.

It should fail. Then install libavcodec52 and then ubuntu-restricted-extras again.

If it doesn't work for you through the commandline try the Package Manager....see if that will handle it.

I'll take a look at that Openshot ppa when I have some time.

I just double checked the process using the Package Manager.

Installing the 46 packages that go along with ubuntu-restricted-extras fails.

Install libavcodec52 and the entire process succeeds....but in that order.

Yes, as i understood key way is in uninstall libavcodec52, install ubuntu-restricted-extras and again libavcodec52. And on second installation libavcodec52 via Package Manager required libavcodec-extras-52 are included in libavcodec52.
Reasoning above there is no libavcodec-extras-52 in originally installed libavcodec52. I can't understand the magic but it is )
