I am trying to add some files to iTunes: some .wma files which it will not import, and some .m4a files which it will import but not play because it does not know bitrate or duration.
I have tried the following:
- converting with VLC: the files all play fine in VLC but I can only convert them one at a time, despite being able to give multiple files as input for transcoding, which implies batch conversion should be possible.
using ffmpeg to convert the files. This gives the error:
dyld: Library not loaded: /opt/local/lib/libx264.142.dylib Referenced from: /opt/local/bin/ffmpeg Reason: no suitable image found. Did find: /opt/local/lib/libx264.148.dylib/libx264.142.dylib: stat() failed with errno=20`
when I try to reinstall ffmpeg in homebrew, building from source, as suggested in this question on github I get the error message
Error: SHA256 mismatch.
There must be a simple way to batch convert files, either with vlc or command-line tools. How?
