Description-en: Tools for transcoding, streaming and playing of multimedia files
FFmpeg is the leading multimedia framework, able to decode, encode, transcode,
mux, demux, stream, filter and play pretty much anything that humans and
machines have created. It supports the most obscure ancient formats up to the
cutting edge.
.
This package contains:
* ffmpeg: a command line tool to convert multimedia files between formats
* ffserver: a multimedia streaming server for live broadcasts
* ffplay: a simple media player based on SDL and the FFmpeg libraries
* ffprobe: a simple multimedia stream analyzer
* qt-faststart: a utility to rearrange Quicktime files

Hyper fast Audio and Video encoder

Use -h to get full help or, even better, run 'man ffmpeg'

I believe it is obvious there is a conflict between avconv and ffmpeg. But I don't know the proper solution. Thought maybe REMOVE / UNINSTALL all VIDEO programs, REMOVE / UINSTALL FFMPEG, and Re-Install the "Best" Video Editing software for UbuntuStudio v16.04.

Any ideas or suggestions for everyone?
Thanks!

Found info regarding removing "ffmpeg". Here is what it shows in terminal prior to removing.

 $ sudo apt-get remove ffmpeg

Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages were automatically installed and are no longer required:
linux-headers-4.4.0-59 linux-headers-4.4.0-59-lowlatency
linux-image-4.4.0-59-lowlatency
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
devede dvdstyler ffmpeg libav-tools
0 upgraded, 0 newly installed, 4 to remove and 4 not upgraded.
After this operation, 6,841 kB disk space will be freed.
Do you want to continue? Y/n

So if DeVeDe and DVDstyler must be removed, What Video Editor / DVD Creator software is recommended for use with UbuntuStudio v16.04?
And should I remove "avconv / libav"?

Edit Note: Removed "libav". I doubt much has changed since one developers post here;
http://blog.pkh.me/p/13-the-ffmpeg-libav-situation.html

For more History of the fork and confusion between the two, please review the following;

Thanks!

May be more useful to show termnal output from crashing app as there is no conflict between ffmpeg & libav-tools/avconv
(- avconv is just a symlink to ffmpeg as libav is no longer in Ubuntu
