[FFmpeg-devel] [PATCH 1/3] Revert "fftools/ffmpeg_filter: fix the flags parsing for scaler"

[Linjie Fu]

From: Linjie Fu <linjie.justin.fu at gmail.com>

This reverts commit b3a0548a981db52911dd34d9de254c4fee0a8f79.

This breaks the usage of swscale options, scale_sws_opts should be passed
to auto-inserted scale-filters.

The auto-inserted scaler accepts sws_flags in filtergraph complex which
overrides the 'flags' option for vf_scale and dump it in verbose, however
simple filtergraph doesn't override. Hence we got different verbose logs
printed in vf_scale when we specify -sws_flags in cmdline. It's a matter
of log print rather than option parsing.
