export videos without sound

[Manuel Sanchez]

I'm trying export my videos to a mp4, but since I've upgraded to ubuntu 14.10 I can't at all. I've tried to export to a diferents formats, but without any succes. Can you help me?

Ubuntu 14.10. Architecture 32 bits.
Openshot version 1.4.3

[Manuel Sanchez (sanchezcano-manuel)]

No sound in the exportation, image is good.

[Olivier Girard (eolinwen)]

LIke you are on Ubuntu I suspect still a issue with the fork of ffmpeg
present on this distribution Libav which dont have the support for
proprietairy codecs like mp4, acc, mp3, 3gp,...
You have a faq which can help you for resolve this issue.

I confirm this bug also for Ubuntu 14.10. Architecture 64 bits.
The faq given by Olivier don't help as it's an old one and the Medibuntu repository is no more available.
It seams that the installation of libavformat-extra package solves the problem, but this package is no more available in ubuntu 14.10.

[Olivier Girard (eolinwen)]

HI Nizar,
Effectively, Medibuntu repository is dead lately. I'm going to modified it.
Anyway, It was not this one in my mind which I was thinking. Use the Sven
PPA for getting the only and true version of ffmpeg.

[Jon Arnold (jonarnoldsemail)]

That PPA doesn't have ffmpeg packaged for Utopic Unicorn (14.10).

[Jon Arnold (jonarnoldsemail)]

[Olivier Girard (eolinwen)]

After your remark, I've checked and that's right. You have now two
possibilities : either you wait this version either you cheat a bit.
Click on the arrow "technical details about this ppa:
You have two lines that you could add in your sources list (see the ubuntu
doc for that):

deb http://ppa.launchpad.net/jon-severinsson/ffmpeg/ubuntu
YOUR_UBUNTU_VERSION_HERE main
deb-src http://ppa.launchpad.net/jon-severinsson/ffmpeg/ubuntu
YOUR_UBUNTU_VERSION_HERE main

replace YOUR_UBUNTU_VERSION_HERE main by TRUSTY main

Save, update your repositories and install ffmpeg. That should work
and help you to use ffmpeg and all software which are using it like
Openshot for sample.

[Jon Arnold (jonarnoldsemail)]

Actually, it doesn't seem to be any problem with FFMPEG.

I found a solution to the problem here: https://askubuntu.com/questions/541635/no-audio-in-rendered-video-files/548279

It appears to be a bug in the mlt package. I downloaded the linked packages from Debian and it works now.

[Olivier Girard (eolinwen)]

Great news. It was the second possibility even I was focused on FFmpeg.

Although I've followed all your suggestion I still couldn't solve the
problem. It looks like they are not good for my architecture ubuntu 14.10.

[Olivier Girard (eolinwen)]

If you take a look at previous comment, Jon have solved this bug updating his MLT version but he was on Debian.
For you that you are on Ubuntu, follow this FAQ : https://answers.launchpad.net/openshot/+faq/1861
Good luck.

[paolo gagini (pax2you)]

My software:
OpenShot 1.4.3
ubuntu 14.10 arch 64 bit

Same problem.
No solution for now

[Olivier Girard (eolinwen)]

Did you have update your version of MLT i.e today the 0.9.3 .?
The solution is here but perhaps you must check if you don't all old
packages of a previous version before.

[Reinis Zumbergs (reinis-zumbergs)]

I can confirm that for me installing the above mentioned MLT packages solves the issue.

Shouldn't we un-duplicate the #1391109, because this approach doesn't seem to apply for the OP (Manuel Sanchez) here?

[Olivier Girard (eolinwen)]

No because the result is the same and the solution too.

[Letatcest (ksoeteman)]

I have not been able to resolve the problem with the above solutions unfortunately. Not with newer packages.

Although the problem does not occur when I used a seperate .ogg audio file, only when the audio is 'in' the video file itself.

I have 2 error messages, this one starting openshot:

No LADSPA plugins were found!

Check your LADSPA_PATH environment variable.

And this one after rendering a video with audio in the video file:

[ogg @ 0x7ff438003880] Application provided invalid, non monotonically increasing dts to muxer in stream 1: 300224 >= -9223372036854775808

Try to use this faq qor the second error message :
https://answers.launchpad.net/openshot/+faq/2645
----

That looks ok, however I did install updated version as described in this post:
http://ubuntuforums.org/showthread.php?t=2249218&page=3&p=13185295#post13185295

libmlt, was the problem for me and ppa mentioned in both did fix the problem.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Ganesh (ganeshprasadh)]

Just posting the solution grabbed from Ubuntu forum. It works instantly.

1 - open a terminal and type: sudo add-apt-repository ppa:sunab/kdenlive-release
2 - sudo apt-get update
3 - sudo apt-get install libmlt6
4 - sudo apt-get install libmlt++3

Thanks.

[Guilherme Augusto de Almeida Filó Maia (guilhermefilo)]

Updating libmlt fixes the bug indeed.
I manually downloaded the packages from Debian packages and installed them using dpkg.

[Tim K (kelletim)]

This bug affects me as well. Pretty horrible.

lame install
libmlt++3 install
libmlt-data install
libmlt6 install
libmp3lame0:amd64 install
libtwolame0 install
openshot install
openshot-doc install
twolame install
ubuntu-restricted-extras install

[David Anderson (davea42)]

libmlt libmlt++3 in Ubuntu 16.04 are still 6.0.0.0-2 .
So openshot still won't generate sound in an output video.
Debian current is 6.4.x.x for some x.x.
Openshot 2.3.4.

While nothing in openshot says what the grayed-out square/circle/slash
related to sound
in the attached property screenshot mean it is perhaps a hint
openshot won't write some sound?

[David Anderson (davea42)]

With 16.04 x86_64 , Ganesh's suggestion is no help. The ppa has libmlt 6.0.0.0-2 too.

[David Anderson (davea42)]

The suggestions about libmlt libmlt++3 and getting same from current
debian (current there is libmlt++3_6.4.1-5_amd64.deb libmlt6_6.4.1-5_amd64.deb)
won't install on x86_64 16.04 without getting several other things.
There are conflicts. Ugh.
