Hello,

I use Kdenlive 0.9.10 on Ubuntu 14.04 and I tried to render a project that I made, but everytime I hit render it gives me the message "waiting" and nothing happens but only overloading the system until kdenlive just close itself.

I tried to render on mp4 and matroska profile.

Which can be the problem? Or the solution?

Thank you.

Hello,
Unfortunately in Ubuntu 14.04-LTS, MLT (media framework used for rendering) and LibAV (codec library) are shipped in versions that don't fit well together.
The solution is to update MLT (& kdenlive) from ppa:sunab/kdenlive-release

Thank you for your answer but my Kdenlive is already the newest version according to this:

You are probably at the newest officially shipped version. But not the newest version. Try ppa:sunab/kdenlive-release or a prebuilt binary daily build version https://userbase.kde.org/Kdenlive/Manua ... ily_builds.

Now, I am sure I have the newest version after removing and reinstalling from ppa:sunab/kdenlive-release, but the problem persists.

Just look at this, where my file is called untitled.mp4 and rendering message is 'waiting', the file size is fixed at 48 kB.



I am rendering for mp4, H.264/AAC (CBR). I tried other profile but with the same result.

What am I doing wrong?

L.E. - Rendering crashed and some error log

Rendering of /home/fujitsu/kdenlive/untitled.mp4 crashed

and some error message that say the computer does not have enough memory.

I'm having the same problem. This thread hasn't moved in 5 days, have people given up on this?

I suddenly have this "WILD TIMESTAMP" issue too. And I note it happend after an update of avconv package. I have solved it by running a dailybuild version of kdenlive. The daily build versions come with their own ffmpeg so you don't have compatability issues with avconv

I've tried the last few daily builds, but they all fail to launch,

What flavour of OS are you on.
Is it 32 bit or 64 bit?
Which daily build file did you down load?

I'm on Mint 17.1. I've tried a few of the daily build from last week for both the LTS and the latest Ubuntu version.

Any ideas on this?

Ubuntu flavoured distributions make about 90% of the trouble posts here. I observed the Ubuntu workflow like this:

Most of the ubuntuish OS users...
1. Try and kick the versions from the standard repos
2. Try ffmpeg and stuff from a less restricted repo (multiverse?)
3. Try the sunap ppa (see https://kdenlive.org/download-development)
4. Try daily builds (https://kdenlive.org/download-development)
5. Switch to another linux distribution (myself having an excellent experience with Archlinux since 2011 and good experience with openSuse in the years before) Caution: Archlinux is in rolling release transition from KDE4 to KDE Framework 5 - kdenlive is usable, but for some reason the menu bar is currently missing.

Most of the users stop somewhere around step 3 or 4, some proceed to step 5.

You mentioned the daily builds would not start. This could be because you did not download the correct build for the bitness of your system.

Is your mint a 32 bit or 64 bit install?

Which of these flavours did you use:
kdenlive-fedora17-x86_64-YYYYMMDD.tar.bz2
kdenlive-ubuntu12.04-x86_64-YYYYMMDD.tar.bz2
kdenlive-ubuntu14.04-x86-YYYYMMDD.tar.bz2 (no 64 in the name )

Capslock: I've tried steps 1 to 4. I'm not switching distros.

I've tried both kdenlive-ubuntu12.04-x86_64-YYYYMMDD.tar.bz2 and kdenlive-ubuntu14.04-x86-YYYYMMDD.tar.bz2 (no 64 in the name ). Still no luck.

Yeah, I have seen that in the other thread. Damn that there is something going completely wrong on your system, while it is running like a charm and without crashes or render problems here... But I can accept you do not want to switch your distro.
