kdenlive and 13.1

stormtracknole · 07-08-2010, 04:05 PM

Building kdenlive and mlt are a bit tricky. There are a quite a few dependencies that need to be met, especially with ffmpeg. In fact, ffmpeg is almost the culprit as most people fail to build it correctly. Glad to hear that you got it working though. :-)

FFMPEG is like the humble guy who takes all the abuse because he was responsible for most (if not all) mishaps in the past

You have no idea how many useless battles i fought with ffmpeg before i turned my attention elsewhere to solve this problem! (though i must admit... ffmpeg does demand decent attention)

In my case the culprit was mlt. The readme of mlt said something like... 'you may require libquicktime if you plan to use kdenlive'

Good catch on that! I'll notify the slackbuilds.org staff and have them
change that part of the documentation.

OP here, I pretty much gave up with kdenlive although maybe since you're successful with building it could you make a tutorial for building kdenlive with a fresh 13.0/1 install?
Also I have libquicktime and kdenlive still no worky

What is the output of the following command:

Code:

grep -l avformat /var/log/packages/*

This will tell me whether or not you built ffmpeg and mlt correctly.

This post in kdenlive forum helped me. Specifically... i used the following information:

Code:

ffmpeg was compiled with:
./configure --prefix=/usr --enable-shared --enable-libmp3lame --enable-gpl --enable-libfaad --enable-libfaadbin --enable-libvorbis
--enable-pthreads --enable-libfaac --enable-libxvid --enable-postproc --enable-x11grab --enable-libgsm --enable-libx264 --enable-libdc1394
--enable-nonfree --disable-stripping --enable-avfilter --enable-libdirac --disable-decoder=libdirac --enable-libschroedinger
--disable-encoder=libschroedinger --enable-avfilter-lavf --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-version3

MLT compiled with:
./configure --prefix=/usr --enable-gpl --qimage-libdir=/usr/lib/ --qimage-includedir=/usr/include/qt4 --avformat-swscale --enable-mmx

I customized the build options by using 'Edit build options/flavours' item in sbopkg and the 'edit slackbuild' option. The options that i used in "Edit build options/flavours' for ffmpeg is as follows:

Code:

AMRNB=yes AMRWB=yes DC1394=yes OPENCORE=yes DIRAC=yes SCHROEDINGER=yes XVID=yes

Most of these depend on other packages...

For some options i could not find in variables like above, i edited the slackbuild file and inserted the following below line 162 (which reads --arch=$ARCH \)

Code:

--enable-libfaadbin \
--enable-libvorbis \
--enable-libmp3lame \
--disable-stripping \
--disable-decoder=libdirac \
--disable-decoder=libschroedinger \

(just noticed that i may have repeated libmp3lame, when it was already enabled using the 'LAME' variable in slackbuild)

Are you using ffmpeg, mlt and other packages also from slackbuilds.org?
It would be great if you can share the compile options for ffmpeg thats making your kdenlive detect avformat.... (ffmpeg was the only one where i had to do custom changes in slackbuilds.info file, while following a kdenlive forum post)

Yes. All of the dependencies are from Slackbuilds. I did notice that the order that things are compiled in seems to be very important. There are a lot of dependencies so you have to go through each one to find the ones that are required at build time. I had to make a chart so that I could visualize what needed to be build and installed first.
I noticed while reviewing the file that mlt needs ffmpeg and I think it may need it at build time. You may just need to rebuild mlt and you will be golden. Worth a try anyway.
