fftools/ffmpeg_filter: fix the flags parsing for scaler
Scaler relys on "-sws_flags" option to pass the flags to swscale
and scale filter. Currently passing "sws_flags=xxx" as a filter
option to scaler leads to an incorrect option parsing.
Check and change the string to "flags=xxx" and dumped flags information.
(Refer to parse_sws_flags())
CMD:
$ffmpeg -v verbose -i input.mp4 -sws_flags lanczos+bitexact+accurate_rnd \
-vf format=yuv420p,scale=800x600 -an -vframes 10 -f md5 -
