Hi there,
When I was testing if fmtconv could make transforms from 709 content to ciexyz content, I may have encountered a possible bug.
I either get a segmentation fault or completely black output when converting 709 primaries to ciexyz primaries.
Code:
import vapoursynth as vs
core = vs.get_core()
core.std.LoadPlugin(path=r'/usr/local/lib/vapoursynth/libimwri.so')
clip = core.ffms2.Source(r'/home/andy/Sample.mkv')
clip = core.std.Trim(clip, 2300, 2300)
clip = core.fmtc.bitdepth(clip, bits=32, dmode=6)
clip = core.fmtc.matrix(clip, mats='709', matd='RGB', col_fam=vs.RGB, bits=32)
clip = core.fmtc.transfer(clip, transs='709', transd='linear', bits=32)
clip = core.fmtc.primaries(clip, prims='709', primd='ciexyz')
clip = core.fmtc.transfer(clip, transs='linear', transd='2084', cont=1000/10000, bits=32)
clip = core.imwrif.Write(clip, 'EXR', 'image%04d.exr', firstnum=0)
clip.set_output()
Is this a bug? If so, I would appreciate that it be fixed. If not, then what am I doing wrong?
