Summary0002766: audio codecs available but not supported, resulting in rendering avi, mpeg4, xvid4 and others not possible
Descriptiongeneral example:
want to render in avi format (avi DV)

not possible as audio codec pcm_s16le is not supported (but available on my system)

similar result with other formats (e.g. mpeg4, xvid4 etc. but other audio codecs are not supported then)

see attached picture
Steps To Reproduceclick render
select format (e.g. avi)

attention: I am running on a different machine old ubuntu 10.04 with kdenlive 0.9 (before: 0.7.8 / 0.8 / 0.8.2.1)
without such an issue.

to see that many people have the same problem, please google as follows: "Nicht unterst├╝tzter Audio-Codec: pcm_s16le"

There may be several reasons for this problem.
The first step is to run the Config Wizard from Kdenlive Settings menu, which will trigger the detection of available codecs.

If that does not work, there are 2 steps to check.


1) check that your FFmpeg / Libav install supports the wanted codec. For example to check for pcm_s16* codec, in a terminal:

ffmpeg -codecs | grep pcm_s16

(replace ffmpeg with avconv if using libav) Will output something like:
DEA..S pcm_s16le PCM signed 16-bit little-endian

Make sure you have the 'E' as second letter which means it supports encoding.


2) Check that your MLT installation gets the correct info from ffmpeg. In a terminal, run:

melt color:red -consumer avformat: acodec=list

That will output the list of available audio codecs (replace acodec with vcodec to see video codecs).

______________________________________________________________

If step 1 fails (ffmpeg not reporting your codec) you either miss some libraries or your version of FFmpeg / libav is broken (I have seen problems in Ubuntu with libav not correctly reporting its codecs despite they are installed).
I just committed a fix in Kdenlive that will enable user to bypass the codec detection and try to encode anyways.

If step 1 is ok but step 2 fails, you probably need to upgrade MLT to a newer version.
