There is a ticket here related to using libopenjpeg with jpeg2000 in MXF: https://roundup.libav.org/issue2309. Decode of jpeg2000 with MXF using libopenjpeg gives an error that only the first component is used. SMPTE 422M defines how the jpeg2000 color data is stored in MXF and I don't think the MXF demuxer incorporates this. If it helps gstreamer can demux the jpeg2000 via mxfjpeg2000.c.
