Audacity Forum

You've not quoted any version numbers, but version numbers are probably the key to solving the problem. My understanding is that FFmpeg in Fedora is built without support for "restricted" formats, so that sends you to building FFmpeg from the source code. According to the Audacity ...

Have been reading/learning about compiling from source. Having successfully installed a local build of a supported version of ffmpeg I set about grabbing Audacity source and building. It installed successfully but I still cannot import wma files - which is something that my Windows version ...

So I can --enable-shared-library because it will still restrict it within usr/local? --enable-shared will build .so files for FFmpeg that Audacity can use. Installation of FFmpeg should default to /usr/local. You can always force the installation directory with ./configure --prefix=<directory> ...

Ah okay. Thanks :0)

So I can --enable-shared-library because it will still restrict it within usr/local? Nice.

Don't mess with system FFmpeg. Build your own FFmpeg 2.3, install it to /usr/local/ (the default location) and link Audacity to that FFmpeg. The linkage "should" happen automatically if pkg-config does its job. The whole point ...

... be able to get at all of them, patent and licensing restrictions aside (but noted). I read that even if compiling locally Audacity only supports ffmpeg up to version 2.3. Not surprisingly my current system (Fedora 23) has version 2.8.6 installed via other software, and even later versions of ...

Your project opens now, that is the main thing. The FFmpeg errors are "normal" if you do not have FFmpeg installed. You seem to have two orphan block files. I think these are the last few seconds of left channel and right channel audio that ...

I think .MOD is JVC being funny.

IIRC, it's just an mpeg, named differently. You can just change the extension to .mpg, but not to .wav. That will result in Audacity producing white noise. If you name it .mpg, ffmpeg will extract the audio. If ffmpeg is installed, of course.

Exporting to mp3 adds silence at the beginning of the file and truncates the sound at the end mp3export.png Both LAME and FFmpeg add about 54ms of silence to the beginning of the mp3 file, which makes for a noticeable pause. The file length is increased to 46,080 samples instead of ...
