Hi all,
Looking at a timewarp producer issue in Kdenlive, I noticed that the MLT
properties method "mlt_properties_pass_list" does not trigger a "property-
changed" event.
In Kdenlive, we use this "mlt_properties_pass_list" method to pass some
properties on the producer. However, since the "property-changed" event is not
triggered, the properties are not applied on the Timewarp producer that
applies changes to the original avformat producer on the "property-changed"
event.
Is there any reason to not trigger a property-changed event in
mlt_properties_pass_list ?
If this is meant to be, I can change Kdenlive to use a property set method,
but otherwise, it seems reasonable to fix it with this 1 line patch :
