Well, I thought that this problem will be interesting enough for anybody to look into it ;). What I would like to know (and what I cannot find out): Is there a bug in the H264 decoder causing this, or is there a unsupported H264 feature causing this, oris there a problem with the H264 data?
Well, as libavcodec (ffmpeg) decodes the frame with correct colors (see the images in my first post), something must be wrong. On the other hand, as the Intel IPP H264 decoder works well for most streams, there is definitely something weird or unusual in the H264 bitstream from that camera.
Thanks for _any_ suggestions.
