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

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

mlt_frame_get_audio()
Thank you for the answer. I tried to follow the
sources of mlt and shotcut, but without success... I will try your
suggestion.

Hello all.
I wrote an mlt-based video editor that is working quite

video clip,

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
stock "crop"
ilter then provides only the parameters to the

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
