According to a test image taken from
http://www.4p8.com/eric.brasseur/gamma.html ffmpeg's scaler does not
properly deal with... well scaling.
The following pipeline produces a "SUCKS" verdict on ffmpeg 2.8.6:
curl -s http://www.4p8.com/eric.brasseur/gamma-1.0-or-2.2.png \
| ffmpeg -f image2pipe -i - \
-vf 'scale=w=iw/2:h=ih/2' -vframes 1 \
-c:v bmp -f image2pipe - \
| ffplay -i -
Is this a real issue worthy of a bugreport, or is the test image/method
flawed?
Thank you!
