Hi all,
Trying to work a bit with movit, I noticed it does crash when
encountering a tractor embedded in another one. This can easily be
reproduced in Shotcut, or in MLT with following command (it will crash
on frame 50 when the reaching the first frame of the mix tractor:
melt color:red out=200 color:blue -mix 150 -track color:green
-transition movit.mix mix=0.5 -consumer xgl glsl.=1
Crash output is :
melt: filter_movit_convert.cpp:204: void build_fingerprint(mlt_service,
mlt_frame, std::__cxx11::string*): Assertion `effect' failed.
Is this a known limitation of the movit/mlt integration (does not
support embedded tractors) or is there hope that this issue can be
solved ? We are planning to use embedded tractors in Kdenlive to allow
mixing in the same way as Shotcut, so I wonder if it means we can forget
movit...
Thanks & regards
Jean-Baptiste
