I think it was my misunderstanding of the API. I didn't set any flag in the initialisation of the sws context. i just set a zero value because I thought i didn't needed anu interp filters to be active as I was just converting to the same size.
When i added a flag linear or bicubic etc the code works allright. A zero value works for most formats but not for the one in vid1.mov.
Thanx anyway and what a great library swscaler is !!
What about a converter to a compressed format suitable for uploading to GPU like the DDS DXT1,3,5 file formats ? I would love to have such a converter...
