Mkvextract GUI

[DarkDudae]

I have programmed a GUI for MKVExtract. MKVExtract is a great tool programmed by Moritz Bunkus which can extracts tracks, attachments, chapters and tags of any MKV(Matroska) file. This GUI will help you using mkvextract.

If you can help me to find bugs, suggestions... you are welcome!
Remember you need to put this tool into the same folder than mkvmerge and mkvextract.

MKVExtract GUI 1.5.5 (changes made by Kurtnoise13)

-Added French Language.
-Added mkxuncat support (asked by RobuX4 himself to undo matroska files concatenation).
-Added dts and usf files extraction.
-Clean & improve the code.

MKVExtract GUI 1.5.4 (changes made by seth)

-MKVextractGUI can be found at CoreCodec.org.
-Added pre-selection of output path for MKVextractGUI folder, source folder or another path.
-Added new folder creation, name edition, etc in ouput path selection dialog (Browse button).
-Some tips have been translated to english/spanish.
-Add CoreCodec MKVextractGUI project ("http://corecodec.org/projects/mkvextractgui/") link in Help menu.
-Fixed "File no found" extracting bug (in rares cases) when Matroska file and output path have been selected manually.
-Some minor improvements in exceptions and internal bugs.


MKVExtract GUI 1.5.3.1 (changes made by seth)

-Fixed bug if Select Matroska File was closed without any selection.
-Drag&Drop Support.
-Reset button in File Menu.
-GUI redesigned.
-MKVextractGUI folder is the default path to extract the tracks.
-Added automatic recognition of VOBSUB subtitles.


Changelog since MKVExtract GUI 1.5.1 (changes made by seth)

-English and Spanish languages in the same exe file.
-Added XP Style.

Changelog since MKVExtract GUI 1.5.0

-Fixed chapter parser bug. (No more problems detecting different matroska streams/attachments...)

-Fixed ouput folder selection bug.

-Some help tips added.

-.mka and .mks loading added.

Changelog since MKVExtract GUI 1.2:

-Added chapters and tags extraction support. (They will be showed like the rest of tracks/attachments). Chapters can be extracted in XML and Simple(OGG)txt formats. Tags only can be extracted in xml.

-A lot of internal corrections.

-Monospace font for CommandLines.

-Added RM files extraction.(Added in latest mkvtoolnix 0.8.7)

-Added new formats system that will allow you to customize the GUI for future A/V formats actually not supported by mkvextract. For example: QUICKTIME A/V extraction is not supported by mkvtoolnix 0.8.7, but it is for sure that future versions will do. If you check in MKVExtract GUI a track like this:

Track ID 1 (V_QUICKTIME)

Then the program will ask you what output extension you want to assing to that sort of track. (In this case qtv) So the next time you find that sort of track, the program will remember it and will assing the output ext automatically. The new formats are saved into Formats.txt file, so you can edit/delete/add them easily.

(TRACK_TYPE) ext
------------------------------
Example of Formats.txt file:
(V_QUICKTIME) qtv
(A_QUICKTIME/QDM2) qta
------------------------------

You can download it HERE

EDITED: Until seth can upload Kurtnoise changes to project page, latest version (1.5.5) can be found HERE and the sources HERE.

It is programmed in Delphi under GNU License.

Nice util, man!

This is very useful, as mkvextract is the only one that can handle some formats supported by Matroska.

Thanks for this app.

[Affar]

Wooow

Great job Dark

[ChristianHJW]

Mosu ! We need this in the mkvtoolnix pack for win32 !!

[scrat]

Hey!

I got an CRC-error and could not extract your GUI. Could you please check if the archive is broken? I have the newest version of Winrar...


cu, scrat

[DarkDudae]

@scrat

Yeah, I checked it and it works perfectly

Anyways, I uploaded a zip mirror, you can download it HERE

[scrat]

Hey!

Thanks. The .zip-version works fine. Great job!

Hi again, I have uploaded the source code (delphi language) and MKVEXTRACTGUI 1.2 final version witch contains cosmetic fixes like:

-Warnings messages if mkvextract or mkvmerge are not detected in the same folder.

-Extract button will only be enabled if one or more files are checked.

-Program window will appear in the center of the screen.

-Some minor internal fixes.

You can download them in the main post.

Greetings

I have a few comments about the interface. First, why the permanent "warning" box there? Why not check the existence of the files required (in current dir and in PATH) at program start and bring a *modal* warning dialog if not found?

Second, the three "options" are not really options, they are actions. The "option" box is not really necessary.

And you may want to use a monospace font for the command lines.

Finally, the code you use to excute the commandline programs are somewhat problematic. Maybe the following sample could inspire you a bit:

function ExecConsoleApp(CommandLine: string; var Output: string): Cardinal;
const
  BufferSize = $4000;
var
  SecurityAttr: TSecurityAttributes;
  ReadHandle, WriteHandle: THandle;
  StartupInfo: TStartupInfo;
  ProcessInfo: TProcessInformation;
  ReadBuffer: PChar;
  BytesRead: DWord;
begin
  SecurityAttr.nLength := SizeOf(TSecurityAttributes);
  SecurityAttr.bInherithandle := True;
  SecurityAttr.lpSecurityDescriptor := nil;
  if CreatePipe (ReadHandle, WriteHandle, @SecurityAttr, 0) then
  begin
    FillChar(StartupInfo, Sizeof(StartupInfo), 0);
    ReadBuffer := AllocMem(BufferSize + 1);
    StartupInfo.cb := SizeOf(StartupInfo);
    StartupInfo.dwFlags := STARTF_USESTDHANDLES + STARTF_USESHOWWINDOW;
    StartupInfo.hStdInput := ReadHandle;
    StartupInfo.hStdOutput := WriteHandle;
    StartupInfo.hStdError := WriteHandle;
    StartupInfo.wShowWindow := SW_HIDE;
    if CreateProcess(nil, PChar(CommandLine), @SecurityAttr, @SecurityAttr,
      True, DETACHED_PROCESS or NORMAL_PRIORITY_CLASS, nil, nil,
      StartupInfo, ProcessInfo)
    then begin
      WaitForSingleObject(ProcessInfo.hProcess, INFINITE);
      (* If you want to do a running update of the output of the console app,
      you would not block here. Instead you could loop while GetExitCodeProcess
      returned STILL_ACTIVE all the while calling ReadFile on the pipe. *)
      // Output := '';
      // Without clearing Output before, its content will be expanded.
      repeat
        BytesRead := 0;
        ReadFile(ReadHandle, ReadBuffer[0], BufferSize, BytesRead, nil);
        ReadBuffer[BytesRead] := #0;
        Output := Output + ReadBuffer;
      until (BytesRead < BufferSize);
      // OemToAnsi(Output, Output);
      // OemToAnsi only works for PChar.
      GetExitCodeProcess(ProcessInfo.hProcess, Result);
    end
    else Result := Cardinal(-1);
    FreeMem(ReadBuffer);
    CloseHandle(ProcessInfo.hProcess);
    CloseHandle(ProcessInfo.hThread);
    CloseHandle(ReadHandle);
    CloseHandle(WriteHandle);
  end;
end;

No, not really. I will place a link on my web page to it, certainly, but including it would only make things problematic. First, it's not my program, it's his. Second, I'd have to update the mkvtoolnix package each time the MEG is updated. Third, it'll cause all kinds of confusion - which version is newer and stuff like that.

Hmm, I still haven't looked at it... this->slap(2);

@Blkbird

Thanks for the tips, I will follow your advices. About my "execute commandline function", I don´t see significative differences respect the one you post. Just that mine waits proccess finish to read stdout of mkvmerge. Anyways, I am thinking at implementing a running stdout of mkvextract in real time for logging purposes, and your lines will be helpful. For example, quicktime tracks extraction is not supported in actual mkvextract.exe, and a realtime log would help a lot with that.

@Mosu

I understand you perfectly, this is a small app that I programmed because I really needed a friendly GUI working with mkv files. I just uploaded it trying to help. I will add some little features, like described before, and I won´t follow with this. I just wait my code can help in future versions of mkvtoolnix tools or other oficial mkvextracts GUIs.

A suggestion for the next release : adding support to extract chapters.

Why don't you read mkvextract's documentation at http://www.bunkus.org/videotools/mkv...kvextract.html or at least the help text it prints if you call it without arguments?

Changelog since MKVExtract 1.2:

-Added chapters and tags extraction support. (They will be showed like the rest of tracks/attachments). Chapters can be extracted in XML and Simple(OGG)txt formats. Tags only can be extracted in xml.

-A lot of internal corrections.

-Monospace font for CommandLines.

-Added RM files extraction.(Added in latest mkvtoolnix 0.8.7)

-Added new formats system that will allow you to customize the GUI for future A/V formats actually not supported by mkvextract. For example: QUICKTIME A/V extraction is not supported by mkvtoolnix 0.8.7, but it is for sure that future versions will do. If you check in MKVExtract GUI a track like this:

Track ID 1 (V_QUICKTIME)

Then the program will ask you what output extension you want to assing to that sort of track. (In this case qtv) So the next time you find that sort of track, the program will remember it and will assing the output ext automatically. The new formats are saved into Formats.txt file, so you can edit/delete/add them easily.

(TRACK_TYPE) ext
------------------------------
Example of Formats.txt file:
(V_QUICKTIME) qtv
(A_QUICKTIME/QDM2) qta
------------------------------

I usually mux .idx subtitles in matroska but then i can't demux it.
I add .idx demux to the wish list...


Sorry my poor english.

This would be a wish for mkvextract, not for the GUI. But I won't implement that. At least not anytime soon.
