Comment (by sulio):
I dont know what reencoding of j2c mean. I trying to encode tiff in j2c or
to decode videofile (h.264,xvid or whatever) in jpeg2000 sequence. Its
encoded,but even if I write option to libopenjpeg in ffpeg commend line
libopenjpeg do not encode in DCI complain format, libopenjpeg do that if
used with another front application like image_to_j2c which is inckuded as
sample in libopenjpeg package. For that reason Im afraid that ffmpeg do
not pass corectly AVoption to libopenjpeg or libopenjpeg is not original
one from OpenJPEG project and is modified in bad way.
I tested j2c files received from decoding using AVoptions but those files
do not pass dci complians test. I guess that specially problem is
"-profile" AVoption that may be is not interpreted like AVoption or
interfere with ffmpeg "global" option.
May be also I dont know something "hidden" about options. May be you
suggest me exact command line that decode h264 file to j2c sequence using
libopenjpeg codec and using AVoption described in -h codec=libopenjpeg
especially profile cinema2K and cinema_mode 2k_24.
Thank you
