MeXgui cross platform Megui port in development

[Jeroi]

Project details:

This is project to port .NET C# MeGUI (WIN only) into QT C++ native WIN/UNIX/OSX operating systems support as well as include new features. Project welcomes all developers to join the porting effort.

Website: MeXgui

Talk: #mexgui @freenode.net

Just one side note: Shouldn't the original MeGUI run on *nix systems thanks to the Mono runtime?

(Of course one would have to replace all the "external" tools with Linux/MacOS compiles)

Well theory it might but is hard, because Megui uses some windows spesifig code and ways to display and encode video. We need to fall using only libavcodec, libmkv, libmp4 and such which can rely on cross encoding the way like handbrake does transcoding with libavcodec. I can see that we can pretty easilly obtain x264 presests from Megui project and things like encoding prosesses from handbrake and so on.

Also Megui uses avisynth where MeXgui should use both Avxsynth and Avisynth. One great advantage with QT is that it is native code for every platform and you should be able to expect the program work where it is build. I gives option to port code to the weird systems also . Another creat feature of QT4 is Phonon, which is native videoplayer widget so we can have easilly video preview nativelly to all systems.


Lots to do still

I have made design choice. I will do instead of how megui does job controlling with SQLlite. This will be an easy method for adding and deleting queve and so on.

Small question: Why Avxsnyth and not Vapoursynth instead? (Is Avxsynth even still developed?)
Also will there be a Qt project file so that one can simple use Qt Creator as development IDE?

Nice, I'm looking forward to read that code. Last time I tried that, I ended up frustrated and switched back to mplayer in slave mode as cross-platform back-end.

Avisynth+ will be coming to Linux too.

No there is only QT4 desinger UI file for main form. All the code for it atm is hand written. I have no QT project file made as I did not feel that necessary for it, I shall take a look into it.

Do please join #mexgui irc chan at freenode to talk about it.

At this moment I am mainly creating variants of megui .net forms to QT forms. If anyone know .net form to QT form generator please advice me and make the work a lot faster.

I have added basic sql functions to create database, open, insert table, insert row, delete and such but theres still much doing.

I have considered to do the forms first and then move to the coding prosess but if the project gets contributors at code base then project starts ongoing a lot faster.

Ok I made now QT project file and cleaned the repo from unnecessary files.

Some updates: Mexgui basic gui dialog "done" only tool bar missing and then prolly some configure to it more later on. x264 dialog tab1, tab2 done...

If the AviSynth support is written correctly (read: dynamically loading the library itself), then there's little reason not to include support for AvxSynth. The amount of code deviation to support both of them is pretty small. Just look at x264 and FFmpeg - as a totally unscientific guess, I'd estimate that 85-90% of the codepaths for AviSynth vs. AvxSynth in x264's input/avs.c and FFmpeg's libavformat/avisynth.c are identical. If you go in and actually quantify the line count differences it might actually be even higher.



The only other general thing I'd recommend is to use mpv rather than mencoder. There's very few things that mpv can't do that mencoder can, but mpv is actively developed (and some of those things can be covered by regular ffmpeg).

1st time I hear of mpv, looks interesting,.. is there some way to get a title<>mpls mapping for blu-ray playback? (I normally know the mpls I want to playback and not the mplayer title)

[Jeroi]

Now x246 config dialog is completed. For one who wants to start importing gui code can now have x264 also implemented in the code.

Edit1:
Now also neroAAC configure dialog done.

Edit2:
Now also Audio configure dialog done which is used for mp3.

[Jeroi]

BIG news. I have succesfully converted all C# code from whole Megui project to C++ with good reputation program. Now project is migrated to C++ and any more misses QT gui dialogs and dialog controlling code changes and other c# to c++ porting code.

[Jeroi]

I am aware that project file is down atm begause I migrated all the cpp files and moved files and so on in the git. Stay tuned.

[Jeroi]

Now the trunk has project file. In future if you want edit something type in aplication folder: qmake -project. Also all project files added to lips and wrappers.

Sorry for incovensies if you have branced old trunk url. The new url is changed in first post.

Qt adopted Phonon at Qt 4.4. Support will remain for the Qt 4.x series, but not for Qt 5. http://qt-project.org/doc/qt-5.1/qtmultimedia/changes.html

phonon works with qt5 http://www.phoronix.com/scan.php?pag...tem&px=MTUwNDM

I am modifying atm avisynth wrapper. Lots needed for changing the dll structure. Firstly qt dont use stdcalls. You define functions showing outside into dll header and combiler handles all calling correctly for every system...

Also finding all M$ code takes time, debugger used a lot for this

Also since this is going to be cross platfrom program I am cosidering to build those dll as statics to include in binary so that we need to build only one time the lib and then just build binary 3 times.

If I'm not misunderstanding either the question or mpv's documentation, this seems to be what TOOLS/mpv_identify.sh (in the source tree) is meant for. I've never used that script nor have I ever really done anything with libbluray support since I only have access to one computer with a BD-ROM drive. I've only built libbluray to make sure it builds and can link to FFmpeg and mpv.

Selur: Are you planning to join development? It would be nice to have more develpoers and also someone who is expert with QT to provide assistant.
