Hi again,
I only want to signal that I discovered something strange:
my crop filter has 6 properties: left-right-top-bottom, plus "width"
and "height". They work correctly in the editor but, when exporting in
XML, "width" and "height" are omitted from the XML file. Of course this
fact polluted

Hi all,
I am writing a video editor using mlt. The editor basically
edits a playlist, inserts filters, and does preview via a swallowed SDL
window. When requested, the editor generates an XML file to be fed to
melt(1). So far so good.
In order to crop clips, I used until now the

Thank you for the answer. I tried to follow the

suggestion.

Hi all,
I succeeded in creating a preview of the unfiltered frames, as
suggested by Dan: I wrote a filter, first in the chain, which extracts
the image.
Now I have another problem: I would like to process frames
to inspect the audio levels. I thought I can use the audiolevel filter
and ask it

Hi all. I am writing a basic video editor based on MLT. At the moment,
I use an mlt_playlist, which lets me append video files, break them in
clips, and connect different filters to different clips. So far so
good, I appreciate
the clean C interface of MLT: congratulations. But
now I'm facing a
