Here are the error messages when running vlc craig_citro.mov on Ubuntu 8.04 (Hardy): VLC media player 0.8.6e Janus [00000304] mp4 demuxer error: MP4 plugin discarded (no moov box) [00000283] main playlist: nothing to play [..] > Hmm, > > All three play fine using VLC on Mac OS X. I guess that on Mac OS everthing works fine, since quicktime is a proprietary format of Apple and perhaps vlc uses some codec that comes with the operative system. > I hate > Ogg Theora.

One thing is which format is technically better, other thing is how we may promote the use of free formats and free software. Mp4 or H.264 could be better technically speaking than ogg-theora, no doubt, but these formats are proprietary and seems to be covered by patents [1] and as we all know, patents are a serious threat to free software. By releasing our contents in open formats, we are supporting the freedom of users to play it using whatever software they choose to use, and the freedom of developers to create that software. Pablo [1] see the discusion in the wikipedia article for H.264 http://en.wikipedia.org/wiki/H.264 http://www.copycense.com/2006/02/att_readies_hit.html (Fortunately, in my country Argentina, our patent law explicitly say that software is patentable!) --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
