Comment (by MasterQuestionable):

 ͏    "sws_flags" indeed worked, per:
 ͏
 https://github.com/MasterInQuestion/attach/commit/e18e5cd26b9d27bacefa685ba70d0d41bc7d7cbc
 #diff-75a0130f1814ba26c23e3a6fc6ce5046620163061d392086bc55e2c13c145bf9L264

 ͏    Probably the "-sws_flags" was problematic..?
 ͏    https://trac.ffmpeg.org/ticket/10993
 ͏    .
 ͏    But to my experience it adequately worked.
 \\
 \\
 ͏    I know this is somewhat off-topic, but discussion right on the
 constrained wiki page...
 ͏    Likely troublesome.

 ͏    I believe the issue affects everything uses BGR: more than just BMP.
 \\
 \\
 ͏    I also tried to add a comment on:
 ͏
 https://github.com/FFmpeg/FFmpeg/commit/3e064f52eb368a373ded6e3704fcf29f1db3ff12
 ͏    .
 ͏    But somehow failed with obscure error?

 ͏    I'm even unable to add comment on:
 ͏
 https://github.com/FFmpeg/FFmpeg/commit/2f2f73dc3ae3fadbf040eb73f217213b1c99ff39
 ͏    ; that of my own...

 ͏    Seems to be sort of auth issue, as I tested in my own repository and
 succeeded.
 ͏    But per:
 https://api.github.com/repos/FFmpeg/FFmpeg/comments?per_page=100&page=4
 ͏    Commit comments should be permitted..?
