flowblade renders without audio #32

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
I was rendering some video clips with new audio, but after the rendering 
progress was finished my movie file had no audio track.

I am using Ubuntu 12.04 and the current flowblade version and I tried different 
rendering profiles, but in all cases the problem occured.

A snapshot of my environment is attached.

Okay, unfortunately I have not been able to reproduce this, so at this point 
I'm taking no action on this Issue. I'm running Ubuntu 12.04 here myself. Some 
further points:

1. I'm leaving this open to see if there are other cases of this bug.
2. Hopefully future versions of MLT  will fix this.
3. I will add a "Write environment Data to File" button so that users can 
provide more information on their runtime environments more easily.

Tried to render attached file. No sound. Also many presets cause a crash in 
Ubuntu 13.10 amd64.

f=mp4
s=1920x1080
hq=1
acodec=mp2
ab=192k
ar=48000
vcodec=mpeg4
minrate=0
b=3000k

I have got the same problem, there is no sound after I render a video. Is it 
because of my settings? You find them in attachment.

I tested this on my system, and I'm unable to reproduce the problem.

By the way, are you using the latest version of Flowblade (0.16) and a 
reasonably new MLT like 0.9.2? For example Ubuntu carries an older version of 
Flowblade than 0.12 that was the release that carries the Fixed Dec 2. 2013 
patch for issues on mp4 rendering.

I updated Flowblade to 0.16 on Ubuntu 14.10 and have still the same problem. 
What's that mlt and do I have to update that manually too? How do I do that?

GoogleCodeExporter commented 8 years ago 
Ok, Flowblade 0.16 and Ubuntu 14.10 are new enough so that no audio rendering 
related problems should be caused by this.

Some things that you can do to try fix or diagnose this problem:

1. Does installing extra codecs with terminal command 'sudo apt-get install 
libavcodec-extra-56' help?

2. Start Flowblade with terminal command 'flowblade', do the rendering that 
causes the missing audio bug to happen and post the full output from terminal 
here.

Ok, I installed libacodec-extra-56 but still no luck.

Here's the output from the terminal:

Ok, it seems this is a MLT issue that has been fixed. Info here:

http://forums.debian.net/viewtopic.php?f=6&t=117482
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=760773

To get your system working you unfortunately have to wait until fixed package 
is available on Ubuntu or manually compile and install repository MLT from 
source.

Thank you very much for the help. With this information and a little help from 
google I found a working solution: The bug is fixed in Ubuntu 15.4. You can get 
the package from the repository and install it like this:

cd $(mktemp -d)
wget 
https://launchpad.net/ubuntu/+archive/primary/+files/libmlt%2B%2B3_0.9.2%2Bgit20
141027-1_amd64.deb
wget 
https://launchpad.net/ubuntu/+archive/primary/+files/libmlt6_0.9.2%2Bgit20141027
-1_amd64.deb
sudo dpkg -Oi *deb
