* cehoyos/master: Set bits_per_raw_sample when reading j2k frames. libopenjpegdec.c: Correctly scale gray16 output if precision < 16 Use rc_max_rate if no video bit_rate was specified when muxing mxf_d10. Store the video bit_rate in the context when muxing mxf. Merged-by: Michael Niedermayer <michaelni@gmx.at>
