Yes, it is. When I originally checked the sws_opts code in, I put it under 
ifdef's (which later became the if() constructs) because the "emulated" 
SwsContext was not a proper AVClass so it would segfault if ffmpeg was 
compiled without swscaler support.

I think the best way to fix all this is to extract all the av_picture stuff 
out of imgconvert and remove the already deprecated imgconvert/resample for 
good :)
