Commit 0b5a98ad authored by Jean-Marc Dressler's avatar Jean-Marc Dressler

A lot of bug fixs for the BeOS side of VideoLAN:

- the vlc does not exhaust system resources anymore (it was creating a new
  mutex each picture so after a while there was no more mutex available in
  the entire system);
- the sound has been corrected and now it works perfectly;
- the window has now the right size (there was and additional line before).

The (BeOS) threads have also been improved especially with the cond vars
(but it is no more compliant with the pthread cond vars).

VideoLAN for BeOS now rocks and is ready for its first binary release.
