Yes. That was me. After I wrote here I decided that I will do it myself. ;-) > I nacked this, because ffmpeg is not in all major distributions because > of licensing issues.

But I think that libjpeg-turbo is the only way to go for this high frame sizes. The problem is only that libjpeg-turbo does support restart markers. I hope this just means that it decodes such frames slower: http://libjpeg-turbo.virtualgl.org/About/Performance So as it seems ffmpeg does have problems with decoding such frames (you get garbage) this is one more reason to go with libjpeg(-turbo).
