I used a wildcard for this folder-name in the tar-command:

Code Select Expand

QMAKE_POST_LINK += tar -C $$(HOME)/bin -xvJf FFmpeg/ffmpegLinux.tar.xz --strip=1 --wildcards */ffmpeg

Unfortunately, this wildcard seems to conflict with the dummy file "platform/qt/FFmpeg/ffmpeg". Don´t ask me, why. This is the corresponding error-message:

Code Select Expand


tar: FFmpeg/ffmpeg: Nicht im Archiv gefunden.

If I call tar with the complete archiv-path, ffmpeg is found in the archiv and gets unpacked. No more error.

Code Select Expand

QMAKE_POST_LINK += tar -C $$(HOME)/bin -xvJf FFmpeg/ffmpegLinux.tar.xz --strip=1 ffmpeg-4.0-64bit-static/ffmpeg

This fixes the normal compiling for Linux openSUSE.

If I remember correct, it says something like "FFmpeg/ffmpeg not found". I have an idea, what can help, maybe. But I cannot test this here. Will try it later, when I'm back home.

The new Zero-Byte file "ffmpeg" in platform/qt/FFmpeg breaks unpacking with tar -C--- in Linux openSUSE. If I rename the empty file to let´s say "ffmpeg1", unpacking works like expected

I was still having problems with qmake, unfortunately.  Wanted to let you know that I think "gitclone" should be "git clone" in your translated instructions.

You are right. Looks like I did a copy and past error. Fixed. ThankYou very much.

For your qmake-problems. Just for my Info. Which QT-Version do you use?

Code Select Expand


qmake --version

You only need one single file, called ffmpeg

@all
guide for compiling Mlv-App (english) in Linux: https://sternenkarten.com/tutorial-englisch/
This guide is updated now too.

@masc
I will try the app-image later

edit:
What about ffmpeg? Does the app-image contain ffmpeg?

@escho: hehe, so easy, isn't it?!

Yes, it is 

The German version of the Linux-Compile-Guide is now updated and extended (openSUSE and Kubuntu): https://sternenkarten.com/fotos/ml/
English translation will follow soon

I removed the compiling with qt-creator part. I´m, planning to moove this qt-creator-stuff to a seperate guide (debugging). But this will take some time.

Still having trouble compiling, anyone mind helping me? I'm running 16.04

I have openSUSE here and cannot reach my astrophoto-laptop (kubuntu) before next weekend. Than I can try.

I do a curl command:

Code Select Expand

curl -L https://github.com/ilia3101/MLV-App/archive/master.zip -o mlvapp_master.zip && \
unzip mlvapp_master.zip -d ~/
rm ~/mlvapp_master.zip
Should be the same but will try your clone command tomorrow...

It´s not the same. You download a zip-file and unzip it. But you don´t initialize your local copy to work with the remote repo. If you do a "git clone...", you get all initialized, what you need. Look in the working.dir of MLV-App. There should be a hidden folder ".git".

How did you get MLV-App-master? This is the folder, if you download the zip-file. If you do a "git clone https://github.com/ilia3101/MLV-App.git", the resulting dir shold be MLV-App. In this folder, you can do "git pull"

Than go to your local clone and do only

Code Select Expand

git pull

Tested it with an older mlvapp-backup. Works for me.

Did you try:

Code Select Expand


git pull https://github.com/ilia3101/MLV-App.git

and if this doesn´t help, here is a snippet from my ML-Compile-script. This is hg, but maybe, tjhat can help:

Code Select Expand

repo_clonen()
{
    echo "-------------------------------------------------------------------------------"
    echo "------------------------------clone -------------------------------------------"
    echo "-------------------------------------------------------------------------------"
    cd $hauptverzeichnis
    hg clone -r "$branch" "$adresse"
   
    echo "-------------------------------------------------------------------------------"
    echo "-------------------------------pull -------------------------------------------"
    echo "-------------------------------------------------------------------------------"
    cd $hauptverzeichnis/branch
    hg pull
   
    echo "-------------------------------------------------------------------------------"
    echo "------------------------------update ------------------------------------------"
    echo "-------------------------------------------------------------------------------"
    hg update
}

Thx @escho! I commited your line to the .pro file into the repos!

Great. Tested it. Works.
Than I can update my compile-guides.

To make things more easy for me, I wrote a git-clone and compile-bash-script for openSUSE. If someone is interested, I can upload it to my homepage ( https://sternenkarten.com/ )

Cool. Which version do you recommend? ffmpeg-release-64bit-static.tar.xz ?

Only now, I found some minutes to test the Linux-desktop-file (created with the .pro file). Works perfect here in openSUSE. Thanks for adding.

Great, that you added ffmpeg-static to the sources. I played a bit around in the .pro-file. With this command, I succeded in unpacking only the ffmpeg-bin out of ffmpeg-static and copying it to $HOME/bin. So you don´t need to unpack ffmpeg manually.

Code Select Expand

linux-g++ {
    target.path = $$(HOME)/bin
    desktop.path = $$(HOME)/.local/share/applications
    desktop.files += mlvapp.desktop
    icon512.path = $$(HOME)/.local/share/icons/hicolor/512x512/apps
    icon512.files += RetinaIMG/MLVAPP.png

    INSTALLS += target desktop icon512
   
    QMAKE_POST_LINK += $$quote(tar -C $$(HOME)/bin -xvJf FFmpeg/ffmpegLinux.tar.xz --strip=1 --wildcards */ffmpeg)

}


I´m not sure, that this is a correct way for doing this. It was only try and error, what I did.

edit:

This one is working, too:

Code Select Expand

QMAKE_POST_LINK += tar -C $$(HOME)/bin -xvJf FFmpeg/ffmpegLinux.tar.xz --strip=1 --wildcards */ffmpeg

After having unpacked the ffmpeg, did you copy it to the application directory? Maybe we can add this to the .pro file!?

Yes, I extract ffmpeg*tar.xz, using ark, and copy the ffmpeg-bin-file to the bin-folder in my home-directory. But it would be fine, if I woudn´t have to do this manually.

In /bin/bash I use this syntax to extract only the bin-file of ffmpeg to $HOME:

Code Select Expand

tar -C $HOME/bin -xvJf ffmpeg*.tar.xz --strip=1 --wildcards */ffmpeg
Not sure, how to add this to the .pro file. I will play a bit this weekend and tell you my results.

Cool. Which version do you recommend? ffmpeg-release-64bit-static.tar.xz ?

Yes

Linux static builds for ffmpeg are back again: http://www.ffmpeg.org/download.html#build-linux

@masc
Thanks for the explanation.

Yes, I think it would make sense to add the ffmpeg-static for linux to the repo. Would make thinghs easier. Unfortunately I have deleated my ffmpeg version, so I cannot upload it. But It looks like the static version will be back soon on the ffmpeg-site.

ffmpeg-linux-static-builds

There are no more linux-static-builds of actual ffmpeg-versions available for some time. For more info, please have a look at the ffmpeg-website.

[openSUSE:]

openSUSE:

Did I tell you, that I´m sometimes a bit lazy. So I wrote some lines into the MLVAPP.pro-file. Now qmake-qt5 and make are doing the job for me. Now I have the mlvapp-starter in the multimedia-part of the KDE-Quickstart-menue. And I appended it to my desktop.

Code Select Expand


target.path = $$(HOME)/bin
desktop.path = $$(HOME)/.local/share/applications
desktop.files += mlvapp.desktop
icon512.path = $$(HOME)/.local/share/icons/hicolor/512x512/apps
icon512.files += RetinaIMG/MLVAPP.png

INSTALLS += target desktop icon512


The way to install mlvapp and a desktop-file is now:

Code Select Expand

qmake-qt5
make
make install

Note, that is only valid for Linux-openSUSE with KDE. It should run on Kubuntu as well. Ubuntu with gnome or Ubuntumate could b different. I cannot test Gnome, but I have ubuntumate. I will give ubuntumate a try next days

Tried this with kubuntu 18.04 LTS.

Works for the desktop-file
Compiling need qmake instead of qmake-qt5:

qmake
make

@50mm1200s

Couldn't it use the package manager, instead of copying manually?

Sure, you can use a paketmanager for installing ffmpeg, if you wan´t. I described the way for openSUSE in my guides:

German: https://sternenkarten.com/fotos/ml/
English: https://sternenkarten.com/tutorial-englisch/

Search for ffmpeg...

But remember. ffmpeg shipped with the big distributions is not compiled with all codecs, mlvapp needs. The community provided unofficiell package-repositories, which contain a fully featured ffmpeg. You first must add these repositories to your package-manager to get the correct ffmpeg-version.

Also, there's some security considerations on copying something to /bin...

I don´t copy anything to /bin... , so no security considerations

[mlvapp.desktop]

A word to the desktop-files in Linux

This is the end of the MLVAPP.pro-file:

Code Select Expand

#linux-g++ {
    #Add desktop file
#    EXTRA_FILES += \
#        mlvapp.desktop
#    for(FILE,EXTRA_FILES){
#        QMAKE_POST_LINK += $$quote(cp $${FILE} $${DESTDIR/usr/share/applications/}$$escape_expand(\n\t))
#    }
#}

I guess, this was a try to install a desktop file. But this cannot work for two reasons:

First:

"/usr/share/applications" contains desktop-files, that´s true. But these deskop-files are system-wide. For doing something system-wide in Linux, you must logged in as root or use sudo. You will be asked for the root-password then, to proceed.

Second:

Code Select Expand

"$$quote(cp $${FILE} $${DESTDIR/usr/share/applications/}$$escape_expand(\n\t))"

What is DESTDIR? /usr/share/application is a valid path in Linux. The makefile, created by qmake-qt5, shows:

Code Select Expand

cp mlvapp.desktop

The destination is missing.


I for my part do not want to install mlvapp system-wide. I want it locally in my home-folder ( /home/myusername/ ). So my way for building mlvapp is:

Code Select Expand

- download the static version from ffmpeg for linux from the ffmpeg-website
- copy ffmpeg to ~/bin
- cloning mlvapp from git
- making the buildfile with qmake-qt5
- compiling with make


I wrote a little bash-script for doing this, because sometimes I´m a bit lazy

OK, mlvapp is compiled. All I like to have know, is a little desktop-file. Not because it´s necessary for mlvapp to start. No, I like nice little buttons and icons to press. (That´s a reason, I love to visit the "Deutsches Museum in München". Many buttons to press there...

I do not want to have this desktop-file system-wide to avoid using the root-password. Fortunately, I can create this desktop-file locally in my home-folder. OK, which file must go to what place, now?

mlvapp.desktop

Theat goes to a hidden folder in $HOME

Code Select Expand

$HOME/.local/share/applications

MLVAPP.png (in RetinaIMG)

The png-icon has a resolution of 512x512 px. So it must go to another hidden folder in my home-directory

Code Select Expand


$HOME/.local/share/icons/hicolor/512x512/apps

Another possibility should be, I guess:

Code Select Expand

$HOME/./icons/hicolor/512x512/apps

mlvapp

The bin-file should go to a place, which is describes in the $PATH envirement-variable

Code Select Expand

$HOME/bin

@escho

In Ubuntu long time ago I just made shortcut of MLV App with just simple mouse drug and drop on to my desktop and also have very nice icon there.

Unfortunatly, this doesn´t work in openSUSE and kubuntu 18.04 (atm?). I can start mlvapp from the desktop, but I have no MLVAPP-icon.


@Ilia3101
@masc

src/icon - there you will find icon.png

Hej escho, see MLV_App/platform/qt/RetinaIMG/MLVAPP.png as icon.

Thanks for the paths. Didn´t see them...


@masc

Have you seen the thread on github about how to do a appimage? There were a lot of hints from someone, but I can't help much...
https://github.com/ilia3101/MLV-App/issues/17

I saw it, the part of the Howto. But i didn´t read the part with the appimage.

I´m sorry, but I cannot help with an appimage. That´s beyond my skills. But maybe, I can help a bit with the linux-desktop-file, you know, this one, you wanted to copy to /usr/share/applications. More tomorrrow...

Linux-openSUSE

I played a bit with mlvapp for creating a desktop-file with a nice icon. I found a raw desktop-file in $HOME/MLV-App/MLV-App-master/platform/qt. But this desktop-file needs "*.png *.xpm *.svg *.svgz|Symbol-Dateien" as icons. I only found "MLVAPP.ico", which is not accepted. Not the biggest problem. I opend MLVAPP.ico with GIMP and exported it as png.

The second thing is the path to mlvapp. In the desktop-file, the path is mlvapp. That is fine, but only, if mlvapp is in a directory, which is described in the $PATH env-var. But mlvapp is located in (in my case) $HOME/MLV-App/MLV-App-master/platform/qt. For to run mlvapp by only clicking the desktop-file, the complete path to mlv-app is needed in the desktop-file. I changed this and have now a nice little start-symbol for mlvapp on my desktop:
