Please provide a daytime sample.

[PavelsM]

Sure, here is daytime sample: ​https://www.dropbox.com/s/e0z5o03g1zfmjh3/spot-day.mj2?dl=0

[Carl Eugen Hoyos]

Thank you for the samples!

The regression you see is a duplicate of ticket #3619 - workarounds are to configure with --disable-decoder=jpeg2000 --enable-libopenjpeg or to use ffmpeg -vcodec libopenjpeg -i spot-day.mj2 to force the working decoder.

I keep the ticket open because the internal decoder fails badly even after fixing the pix_fmt. It also shows imo that the current implementation is wrong wrt dcinema profiles and pix_fmts.

Hi, -vcodec libopenjpeg helped, thanks for the workaround.
