Audacity scm Bug Feedback

--- Quote from: Jason W on March 13, 2012, 05:17:38 PM ---I am using OSS a bit with the scm's, and I try to build with support for both alsa and OSS when possible, and so far that has been possible.
I added the tiff dependency, as I use Icewm that is already installed via tcz's so I did not notice. Thanks for finding.

Menu bar
A single alteration made to app setup
Edit-->Preferences-->Import/Export-->Show Metadata Editor prior to export=disable
Result:
This prevented display of some entries in the app menu bar
Minimize then maximize window returned all entries
Recording
Preliminary (quick and dirty) tests
Successfully records static produced by audio card (no audio signal input)
Successfully manipulate recording by removing dc offset
Successfully replay recording
Fails to save via export to wav file; error message "cannot export in this format"
Audacity manually shut down and restarted
Importing
File-->Import-->test.wav (method=read directly from original)
Fails to import file
Auadcity catastrophically closes
Error message in terminal "Segmentation Fault"
Eliminate Hardware
Repeat tests on different hardware on which Audacity has been in continuous use since TC3.3
Results:
Identical to those above
Jason W:
I have found wav files problematic in other apps as well, but I will check it out with audacity tonight.
Jason W:
It seems audacity tries to use ffmpeg to function with wav files. I have a build script to create a static ffmpeg, I will build it and plug it in the extension soon. But for now, installing ffmpeg-ffserver will work.
Jason W:
I added a shared build of ffmpeg version 0.7.11, as audacity looks for libavcodec.so.52 for ffmpeg functionality. If one imports wavs that show up when searching for ffmpeg compatible files, they should work.

I'm not certain what is meant by this.
Successfully tested the import and export of various formats mp3, flac, wma... All work OK.
The problems with wav files are still present. Importing closes Audacity, exporting generates the previously mentioned error message.
To see if they might be related to the version of Audacity on which the scm is based, I tried v2.0.0 from the Debian 6 testing repo in another distro. Note, this is not identified as beta. All worked OK including the import/export of wav files. Might it be worth looking at the newer release?
