Hi all,
In Kdenlive, we often have projects with multiple tracks, and track
compositing is one of the bottleneck we have with MLT.
Shotcut uses the frei0r.cairoblend transition for compositing. cairoblend first
requests an rgba image for the top (b_frame), and checks if it really has

Hi all,
While working on a Kdenlive rendering issue, I noticed that the avformat
consumer duplicates the last frame on encoding. So the resulting file is
1 frame longer than wanted.
This is easily reproducible with:
melt color:red out=10 -consumer avformat:red.mp4
This produces a 12 frames
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 "pro

Hi all,
Following a Kdenlive's bug report, I reproducer a crash in
transition_mix when using a "consumer" producer is inserted in a
playlist, if that producer has a different fps than current project.
Problem is that in consumer_producer, we have that:

Hi Dan, all,
First, thanks a lot for implementing the much anticipated consumer scaling
feature! Nice way to do it! While testing it, I noticed a problem with
transitions.
It seems like the "consumer_scale" property is not always properly propagated
to the frames. Because of this, transitions
Hi Dan, all,
We are approaching the dependency freeze for Kdenlive's 19.12 release and

Hi!
As described in Kdenlive issue 1894 (*), the avformat consumer does not check

The patch below somehow fixes the issue by checking the ret value, but I guess
something better than exit(1) should be possible.
