Kdenlive with melt 0.8.2

How can i use Kdenlive with melt 0.8.2 new version recently released. This release of mlt fixes the memory leak issue, so that i can work with kdenlive smoothly and not eating my memory.

If you are using Ubuntu, mlt 0.8.3 and kdenlive 0.9.3 are available from here:-

https://launchpad.net/~sunab/+archive/kdenlive-svn

Other than that, you will have to use the buildscripts. Oh, and it looks like kdenlive is waiting to build at the moment.

Can't get the recent sunab builds to work: almost all codecs are broken from kdenlive's perspective, proxy clips won't work for probably the same reason ... it's a mess. I'm waiting now for a week for the developers to sort out this mess what happened during transition of libav/ffmpeg/mlt -- but they are probably on their well-deserved vacancies and nothing gets fixed. Sigh.

I have not had any problem lately with sunab's svn. I installed the latest this afternoon and apart from one small bug, which I'll stick in "Bug Chat" below, it seems to be working fine. Actually, it's rendering a Project right now. I haven't created a proxy today but they seem to be working.

I've updated the kdenlive-release ppa with mlt 0.8.2 as it's just e bugfix realease. The kdenlive-svn ppa is only there for testing purpose with kdelive and mlt git snaphots.

@Dive0 : can you detail your install : ubuntu version, libav/ffmeg version ? regular/ppa ?

updated with melt 0.8.2, memory eating bugs are gone almost. previous version of mlt was unable to open the project at all and ate all my 2gb of ram. Still i don't know why kdenlive needs 500mb above for simple editing of Full HD footage.

Okay, deinstalled kdenlive, mlt and frei0r from sunab-cvs ppa and installed from sunab-release ppa. But the same problems persist.

My system: Kubuntu 12.04 64bit, most recent packages installed.

Trying to render a proxy clip gives:

By the way: libmp3lame *is* installeed.

Trying to render the whole video gives instead: unsupported video codec libx264.

:(

Sorry, forgot to list the other package versioning information:

ffmpeg: 0.8.3
frei0r-plugins: 1.3.0
lib-avtools: 0.8.3
kdenlive: 0.9.3
libmlt++3: 0.8.3

Argh, see also the old thread here: http://www.kdenlive.org/forum/solved-unsupported-video-codec-libx264-lib...

The problem are the missing additional codecs, where this package conflicts with other dependencies, so you need to really tell the package system to install libavcodec-extra-53!

But rendering still doesn't work: missing codecs... :(

Clutching at straws here, but I have libmp3lame0 and libsox-fmt-mp3 installed. How about you?

I was wondering whether to query that, easy to miss that one.

Nope, both libs for mp3 are installed. Does not help.

So reading that thread above, you did try deleting the kdenliverc in ~/.kde/share/config, did you?

yes, deleted it over and over again after each step. There is something borked here in kdenlive and tools not properly covered by dependencies.

You said you removed mlt etc when you re-installed, but have you checked that there are not any old mlt versions lurking with:-

ls -la /usr/lib/libmlt*
....................
also I have

libx264-120
libavcodec-extra-53
libavformat-extra-53
libfaac0
and others I suppose.

Just in case.

PS: Have you checked the Wizard to see what codecs you have?

on my system, a "ls -la /usr/lib/libmlt*" gives:

-rw-r--r-- 1 root root 154120 Sep 2 14:41 /usr/lib/libmlt.so.0.8.3
-rw-r--r-- 1 root root 118816 Sep 2 14:41 /usr/lib/libmlt++.so.0.8.3
lrwxrwxrwx 1 root root 17 Sep 2 14:41 /usr/lib/libmlt++.so.3 -> libmlt++.so.0.8.3
lrwxrwxrwx 1 root root 15 Sep 2 14:41 /usr/lib/libmlt.so.5 -> libmlt.so.0.8.3

my libx264 is in "/usr/lib/x86_64-linux-gnu/libx264.so.120" -- could there be a problem with the 64bit architecture?

The Wiz(z)ard says that everything is okay and lists all those codecs, including H.264. So this does not really help to track down any problems, I suppose.

Yes it does help, we know mlt is fine, Wizard says they are all there and I'm using Ubuntu 64bit and it all is working fine.

Nearer the top of this thread you say there is trouble with libmp3lame.

Look at this below .. Post #14 THEN look at the last post:-

http://www.kdenlive.org/forum/pcms16le-codec-not-found-even-though-it-th...

normcross: thanks for your suggestion, it finally solved my problem. I had to manually add libmp3lame as well as libx264 to kdenliverc as described in the thread you linked to above. A first quick rendering test with a 5min video seems to be okay.

DiveO : Don't hijack this thread. Start a new thread for your problem

For me since I up-dated to MLT 8.2, Kdenlive started crashing like a m*****f*****!

It did this before but was fixed in 9.+, (currently on 9.2 which worked fine till now) but now it's back to crashing big time, I can't get reliably through 5 minutes without it crashing out, and it crashes pretty much when switching from full screen.

I'm on Lubuntu 12.04

I've never been able to get the debug tools to work BTW, matter what I install, which is why you're not getting 20-30 crash reports from me a day.
