[Bf-committers] Blender 2.49 (a) Sequencer on Windows

today I used the Blender sequencer in 2.49 on Windows XP for the first 
time and was rather surprised, that _nothing worked at all_.

* Sound seems completely broken (hangs Blender completely, if you activate
   scrubbing, doesn't play the sound at all)
* opening DV-AVI does not work (even with ffmpeg compiled in).

The reason for the later is pretty obvious in the code, since the AVI 
library of blender only supports certain specific AVI codecs (instead of 
using the appropriate Windows functions) and - is specifically for Windows 
tested _before_ testing with ffmpeg. So: we have the somewhat strange 
situation, that the audio track can easily be opened using ffmpeg, but 
opening a simple dvvideo stream within the same file will break on 
Windows. Either, we should shuffle tests around or we should make the 
internal AVI-loader check the files a little more seriously, before it 
tries to open them - even if it doesn't support them.

I tested this with Blender 2.49 and the latest builds on graphicall.org, 
that will most likely become 2.49a on a Windows XP 32bit machine.

I will happily assist anyone, who wants to fix that before release, since 
I don't think, it is a very good idea to release a totally non-working 
sequencer on Windows. (Or we did that already all the time, it was my 
first time, to take a look today - and, if I'm simply too stupid, to do 
Windows, please let me know, and I'll shut up immediately :) )

So long and good night,
