if the openjpeg parameter tcp_rates is not 0 ( using the ffmpeg

every 2nd image per thread is badly encoded. By moving the opj_setup_encoder
function from
libopenjpeg_encode_init to libopenjpeg_encode_frame this can be prevented.
This fixes ticket #3754.
how can this be reproduced ?
note, ive tried:
ffmpeg -i matrixbench_mpeg2.mpg -an -compression_level 1 -vframes 30 -threads 1
-compression_level 1 -vcodec libopenjpeg test.nut
and that results in grayscale only output before as well as after
the patch
you can try with:
ffmpeg -i matrixbench_mpeg2.mpg -pix_fmt xyz12 -format:v jp2 -profile:v
cinema2k -cinema_mode 2k_24 -prog_order cprl -numresolution 6 -numlayers
1 -compression_level 2 -threads 1 test-%05d.j2c
and change the value for -compression_level
