MLT is primarily a development framework. You are strongly encouraged to
use a GUI app provided by your Linux distro such as Flowblade or Kdenlive.
If you decide to continue with your own build, you should let pkg-config do
the work of letting MLT configure find the FFmpeg libs instead of using
--avformat-shared. If you do not know what pkg-config is, then go learn
about it and the PKG_CONFIG_PATH environment variable. If you get through
that, then "melt -query producers" will list the MLT plugins that can read
files or synthesize video (ala color). Look for "avformat". Hope that helps.

Oh blah, I meant to say that the jpeg file *displays* fine, not that it
displaces. Sorry.

Some further info, and two specific questions:
I tried playing a .jpeg file and that displaces.
I can also specify color:red out=25 videofile.mpeg color:green and it plays
the red and green fine but not the mpeg (Or any other video file I've tried
so far.)
I also tried a full path to my mpeg file, and also tried specifying *melt
avformat:/somewhere/here/videofile.mpeg*
None worked.
Question: Is there a command I can type to see if mlt is supposed to be
using ffmpeg to handle video files?
Also, am I correct in my understanding that ffmpeg provides the video codec
support to mlt for a wide range of common video formats?
Thank you very much,
Jesse

Good day,
I am very excited to read about mlt/melt, and and am trying to install and
use it, but may be having some user error.
My understanding is that I should be able to play common video files with *melt
videofile.mpeg*
Unfortunately, it won't work - it just gives usage.
I did compile and install ffmpeg and it works and can play my video files.
mlt does compile just fine, and I tried compiling it with the following
options one at a time, but it never will play my video files.:
./configure --enable-gpl3 --enable-gpl
--avformat-shared=/big/src/ffmpeg/libavformat/
./configure --enable-gpl3 --enable-gpl
./configure
(Followed by *&& make && make install* of course)
However, *melt color:green* plays a green box no problem, and I can mix and
cross fade between different colors and all that.
I'm using the latest slackware 14.2 64 bit for operating system,
I would be most grateful for any clues on what I might be doing wrong and
how to fix.
Thank you and have a great day,
Jesse
