I managed to reproduce the problem with melt:
$ mlt-melt color:red in=0 out=25 -blank 25 color:blue in=0 out=25 -consumer
avformat target=/tmp/export.mp4
+-+ +-+ +-+ +-+ +-+ +-+ +-+ +-+ +-+
|1=-10| |2= -5| |3= -2| |4= -1| |5= 0| |6= 1| |7= 2| |8= 5| |9= 10|
If I attach the audioconvert filter like this, the export works:
playlist.attach(mlt.Filter(profile, "audioconvert"))
When loading the xml, this filter seems to be attached automatically, along
with avcolor_space. But it is not set for the playlist that I create.
Should I wrap my playlist i
