I came across this while testing OD-import using FFmpeg (which seems to work fine). I don't think this is a release blocker for 2.0.1. Possibly P3 (if it is not already in Bugzilla - I couldn't find it) as there is a simple workaround - don't use FFmpeg to import stereo AIF files. Cross-posting to -devel as it is up to RM to decide the severity of this bug. Audacity 2.0.1. Mac OSX 10.7.2. Clean install (no audacity.cfg file, no 1.2.x prefs existing on the system). FFmpeg files in standard location and found on startup. Start Audacity. File > Import > Audio; choose "FFmpeg-compatible files" then choose a WAV or AIF file - the file imports with libsndfile complete with the "uncompressed file warning" dialog. Delete track Preferences > OK - note that audacity.cfg is created at this point. File > Import > Audio; choose "FFmpeg-compatible files" then choose a stereo AIF file - the file imports as silence Log says: 11:45:00: File name is /path/to/file.aiff 11:45:00: Mime type is * 11:45:00: Opening with libav 11:45:00: Open(/path/to/file.aiff) succeeded Delete track File > Import > Audio; choose "FFmpeg-compatible files" then choose a MONO AIF file - file imports successfully Delete Track File > Import > Audio; choose "FFmpeg-compatible files" then choose a stereo WAV file - file imports successfully Delete track Preferences > Libraries; check "Allow background on-demand loading"; OK File > Import > Audio; choose "FFmpeg-compatible files" then choose a stereo AIF file - the file imports as noise Delete track File > Import > Audio; choose "FFmpeg-compatible files" then choose a MONO AIF file - file imports successfully -- Bill |
