Here's my case code C++
。。。
Producer* producer1 = new Producer(profile,"avformat", "/Users/linximing/Movies/55_1726454285_raw.mp4");
producer1->set_in_and_out(400, 440);
{
Mlt::Filter f = Mlt::Filter(profile,"affine");
f.set("transition.rect", "0/0:50%x50% 1");
f.set("transition.valign", "m");
f.set("transition.halign", "c");
f.set("transition.distort", 0);
f.set("transition.fill", 1);
producer1->attach(f);
}
Producer producer3 = Producer(profile,"color", "#990000");
producer3.set_in_and_out(0, 20);
Mlt::Playlist playlist(profile);
playlist.append(producer3);
playlist.append(*producer1);
Mlt::Transition transition2(profile, "luma");
int targetIndex = 0;
playlist.mix(targetIndex, 10);
playlist.mix_add(targetIndex + 1, &transition2);
。。。
A red error message appears at the place of transition, and the effect of zooming out does not take effect. Can anyone tell me where this bug is?
