I have used both the portable version fom portableapps.com 3.1.12 and the latest 3.1.13 alpha from audacity homepage and i got to preferences->libraries and locate the avformat-52.dllfrom the zip package on this link http://manual.audacityteam.org/index.ph ... tallffmpeg but i still get the message FFmpeg "library not found".

What's up with that?

Please note, the Beta/Alpha versioning is "1.3.x".

The zip should work - it is the same version of FFmpeg as the installer.

Please review the instructions here, just to be sure:
http://manual.audacityteam.org/index.ph ... tallffmpeg

As stated in the instructions (Installation), please make sure you use the "Browse" button in the "Locate FFmpeg" dialogue and explicitly select and open the unzipped "avformat-52.dll". The path shown in the text box in the dialogue could be incorrect if you have previously downloaded FFmpeg, so it's important you use the Browse button to select the correct file.

Also make sure you have not got other versions of FFmpeg elsewhere on the computer that may be causing a conflict.
To check this, search for av*.dll on your computer. Include hidden files and folders in the search. Delete any conflicting libraries you find.

If there is still a problem after following the above information, please click Help > Show Log... in Audacity, right-click and Select All, then copy and paste the debug data into your reply.

Please note that Audacity Portable is a completely separate project from Audacity and we do not automatically know what modifications they make to our code. Therefore in most cases, asking support from them, as you have done here:
http://portableapps.com/node/24684

is preferable.

Ok i searched for it, and it seems that Google Chrome and M4A to Mp3 converter by Hootech are the other applications with the avformat-52.dll.

So what now? Do i have to delete the file from their locations?

Obviously if you don't want those applications to use FFmpeg you can delete their FFmpeg library files. Chrome doesn't ship with FFmpeg so I assume you have installed some Chrome extension that does. Audacity can convert M4A > MP3 once you get FFmpeg working.

These sort of conflicts usually occur because an application has put the other FFmpeg versions in the PATH environment variable. If you want to keep the other FFmpeg libraries, you would need to post the output of Help > Show Log so we can see what is in PATH.

You could also try setting the path to wherever you have put the Audacity avformat-52.dll in the audacity.cfg settings file. Exit Audacity then open the .cfg file in a text editor and add lines in this syntax:

Code: Select all

[FFmpeg]
Enabled=1
FFmpegLibPath=C:Program Files (x86)FFmpeg for Audacityavformat-52.dll

adjusting the path as necessary - retain the double backslashes ( ). I can't guarantee it will work if you keep the other FFmpeg versions but it might. The audacity.cfg file is inside the following folder:

- Windows 98/ME: WindowsApplication DataAudacity
- Windows 2000/XP: Documents and Settings<user name>Application DataAudacity
- Windows Vista and 7: Users<user name>AppDataRoamingAudacity

Sorry, I meant Help > Show Log (the same output I asked for in my post before that).

Have you tried setting the path to FFmpeg in audacity.cfg using this syntax?

Code: Select all

[FFmpeg]
Enabled=1
FFmpegLibPath=C:Program Files (x86)FFmpeg for Audacityavformat-52.dll
It would be a quicker solution if it works.

Yes, i tried editing the cfg but it didnt work. IT said that audacity was properly configure before, but now something went wrong, and i have to go to libraries and re-configure.

Here's the sow log info

BTW The standalone version gives me the same issue, that's why i continue asking for help here even though i am planing to use the protable version.

Thanks for the output. If you change the FFmpegLibPath in audacity.cfg I would expect a message that the configuration was changed, because Audacity cannot detect FFmpeg automatically. If your FFmpegLibPath in .cfg is correct, go to the Libraries preferences and click "Locate". If there is no conflict, you should then get a message that the libraries have been detected.

If that doesn't work, the output suggests you don't have the location of those other two FFmpeg libraries in your system PATH, is that correct? And you have the Audacity FFmpeg in "C:UsersMakisPortablesAudacityPortableAppFFMpeg", but not in "C:Program FilesFFmpeg for Audacity"? Have you got the Audacity FFmpeg libraries anywhere else, such as in the 1.3.13 installation folder? If so, remove them, so that the only Audacity FFmpeg is in "C:UsersMakisPortablesAudacityPortableAppFFMpeg", and try to locate FFmpeg in preferences again.

If it still doesn't work, please attach your .cfg file. The only other place to go if your cfg file matches with the place you have Audacity FFmpeg is to download Dependency Walker:
http://www.dependencywalker.com/

Drag audacity.exe from the 1.3.13 alpha installation folder into Dependency Walker, File > Save the .dwi file and e-mail it to me (gale_AT_audacityteam_DOT_org, replacing _AT_with "@" and _DOT_with "." as per normal e-mail address format).

Please try the other solutions above first.

Tried everything but still couldnt make it work. So i emailed you the cfg and dwi files. Whenever you get a chance have a go at them, and if possible come back to me, with a possible solution.

The .cfg file should have the "Enabled" line at the top as in the syntax I gave, so:

Code: Select all

[FFmpeg]
Enabled=1
FFmpegLibPath=C:UsersMakisPortablesAudacityPortableAppFFMpegavformat-52.dll
not:

Code: Select all

 
[FFmpeg]
FFmpegLibPath=C:UsersMakisPortablesAudacityPortableAppFFMpegavformat-52.dll
Enabled=0
Please exit Audacity, edit the .cfg file as in the first code snippet in this message, launch Audacity and if you see the warning about FFmpeg being correctly configured before, go to Preferences and use the Locate button.

I don't see that it should matter on a case-insensitive file system such as Windows, but Audacity Portable say the directory should be "FFMPEG" not "FFmpeg".

The .dwi file for Audacity Portable shows a few expected errors but they are not ones that shed any light. If entering the .cfg file information correctly does not help, can you drag the avformat-52.dll from C:UsersMakisPortablesAudacityPortableAppFFMpeg into Dependency Walker, and send the .dwi file for that.


Thanks
