- lack of (really) active maintainer for the the VLC OSX port.
- Apple Computers Inc. operating system support for POSIX standards is horribly obsolescent (say compared to Linux distributions) and broken.
- Some of the VLC 1.0 core enhancements and changes are not compatible with OSX in their current form.
For the technical details, you should refer to the vlc-devel archives. Anyway. One seemingly potential solution out of this involves dropping support for version 10.4. Since the feature freeze and planned release of VLC 1.0 are drawing very close, fixing the OSX is way overdue. If it does not happen really soon now, we will end up either delaying VLC 1.0.0 to no end because of the OSX port, or shipping VLC 1.0.0 without OSX support. VLC 1.0 brings much needed enhancements and fixes to the Windows and Linux port. Hence, I am confident that we will not significantly postpone the release on all platforms (and as a Linux user myself, I also hope so). We are trying to build a world-class modern media performance and streaming framework, and that excludes limitting ourselves to the lowest common denominator of all operating systems.
I am sure we will get our share of whining with this proposal, especially if it is implemented. Let it be known that I do not care. When millions of people use your software, whining users are a more often than daily occurence, no matter how excellent/crappy your software may be. You simply cannot satisfy everyone, especially when your project is constrained by the time and motivation of a few core open-source developpers.
So anyway, if you care about VLC on MacOS X, especially on MacOS X.4, take this as a call for help. As usual we are looking for source code patches, not for money, hardware donation or moral support.
