Unable to load jpegs created in gimp.

 I chose this software because all the reviews said how easy it would be.  Four days later, I have nothing. 

[eumagga0x2a]

Ok, I ran it. Now what?

If the command finished with a success, you should be able to run Avidemux by executing

Code Select Expand

avidemux3_qt5

If the command finished with a failure, you should have posted the error message.

[Jan Gruuthuse]

Probably you still need to install the newly create debs:
Go into folder with debs:

Code Select Expand

cd ~/avidemux2/debs
Remove developer debs:

Code Select Expand

rm --interactive=never *-dev.deb
Install remaining debs

Code Select Expand

sudo dpkg -i *.deb

now you should either find:

Code Select Expand

/usr/bin/avidemux3_qt5 or

Code Select Expand

/usr/bin/avidemux3_qt4
open terminal and try one of above, this should start avidemux.

[eumagga0x2a]

Probably you still need to install the newly create debs: [...]

No, no, no! If compilation was successful, the installation will be performed by the same script at line 13: https://github.com/mean00/avidemux2/blob/master/createDebFromSourceUbuntu.bash#L13 (unfortunately, the script will proceed with the installation even if the build returned an error, which should be fixed).

now you should either find:

Code Select Expand

/usr/bin/avidemux3_qt5 or

Code Select Expand

/usr/bin/avidemux3_qt4

Presumably only the first one (qt4 build requires the --enable-qt4 option passed to bootStrap.bash which is not the case here).

[Jan Gruuthuse]

If QT5 is not on the system? Or does the script install this one to?
If no QT5 then:

Code Select Expand

cd ~/avidemux2 && bash bootStrap.bash --deb --enable-qt4 --without-gtk --with-cli

[eumagga0x2a]

The script installs Qt5, which amounts to an outdated version 5.2 on Mint Rebecca.

It looks for me like 3d420 were uncapable of handling any complexity, so please let us keep everything simple.

[3d420]

It looks for me like 3d420 were uncapable of handling any complexity, so please let us keep everything simple.

Yes please!
I don't understand any of this, and your disagreement above tells me I am not alone.
Please give me complete instructions. If you don't tell me how to do it exactly, I will do it wrong. I have absolutely no experience in any of this.
After I ran the commands you gave me last night, I can't find any folder for avidemux anywhere, and my software manager does not list it. I finally went to sleep.

[3d420]

I hope you see this as an opportunity to create a clear set of instructions. This kind of frustration is why people go back to windows. 

[Jan Gruuthuse]

Check If your CPU supports 64-bit, you could install a 64-bit OS Ubuntu LTS or Mint. 32-bit is a little dated these days.

[3d420]

My computer is older than dated. It is definitely not 64 bit.
And now an avidemux folder has mysteriously appeared. How should I proceed?

[eumagga0x2a]

And now an avidemux folder has mysteriously appeared. How should I proceed?

I have not a slightest idea, which "avidemux folder" you mean, but the question how to proceed has been answered in http://avidemux.org/smif/index.php/topic,17287.msg78103.html#msg78103. In doubt try to run

Code Select Expand

avidemux3_qt5

in the terminal and in case no Avidemux window appears, post the error message shown in the terminal.

[3d420]

avidemux3_qt5: command not found

[eumagga0x2a]

This means, either the build of Avidemux (or just the part of Avidemux which provides the graphical interface) failed or we've got a Qt4-flavour of Avidemux (unlikely, but who knows) as Jan has suggested.

If

Code Select Expand

avidemux3_qt4

returns "avidemux3_qt4: command not found" as well, we have no other option as to track the failure and to see if anything can be done to avoid it (please note that I have very little time to guide you unless you get used to read what commands run in terminal tell you yourself).

If you have an "avidemux2" folder in your home directory, please look with a file manager into it if there are "deb" and "install" subfolders and if the former is empty, which of the "build*" folders exist.

If you don't have any of the "build*" (buildCli, buildPluginsCLI, buildPluginsQt5, buildQt5, buildCore, buildPluginsCommon, buildPluginsSettings) folders, you didn't even try to start building Avidemux. In this case you failed to follow step 5 (or even 4) of the instructions given in http://avidemux.org/smif/index.php/topic,17287.msg78085.html#msg78085. Only in this case resume with

Code Select Expand

cd ~/avidemux2 && bash createDebFromSourceUbuntu.bash

If there are some "build*" folders but not the others, please post what

Code Select Expand

ls -d ~/avidemux2/build*

returns. This would allow to understand roughly which phase of the build failed. In this case, the next step would be to run

Code Select Expand

cd ~/avidemux2 && bash bootStrap.bash --deb 2>&1 | tee ~/adm-build.log

and once the build fails, compress and attach the "adm-build.log" text file (it may be too big to attach even if compressed). If it is impossible to attach the log, you'll have the choice either to open it (not compressed, of couse) in a text editor, find the place which describes the failure and post just that part, or upload it to some file hoster or the content to http://pastebin.com/.

Please note that the command above only tries to build Avidemux, not to install the generated .deb packages on success yet.

[Jan Gruuthuse]

a successful build ends like this:
