Uoti Urpala 13151d7b69 vd_ffmpeg: make "-lavdopts lowres" handling more robust 
Remove the copy of the "lowres" field that vd_ffmpeg kept in its
private struct and use the value from AVCodecContext directly instead.
The copy gave no benefit and it could be set to the wrong value if
someone used "-lavdopts o=lowres=X" (which would change the real value
but not the copy).
