[SOLVED]Kdenlive will not create mpeg4 files on Mageia 7

Postby banjo » Jul 13th, '20, 15:35

I am running an up-to-date Mageia 7 system, and I cannot get kdenlive to create mpeg4 files. Kdenlive reports that the CODEC H.264 is not available.

The CODEC is, in fact installed as shown by rpm

Code: Select all
$ rpm -qa | grep x264

To add to the confusion, ffmpeg is also incapable of creating mpeg4 files. I created a short test video and rendered it as Test.webm. Then I tried to convert it to mp4 using ffmpeg

Code: Select all
$ ffmpeg -i Test.webm Test.mp4

It indicates that the encoder is disabled, which you can see in the output above, "--disable-decoder=aac" seems like an accurate assessment.

So I looked for an encoder in ffmpeg that I might be able to use.

Ffmpeg tells me that it is aware of the codec h264 with two encoders. They both give me the same error, for example:

To create even more confusion, blender is able to create mp4 files with no problem, apparently using the same H.264 codec.

I don't understand how the CODECs hang together in the system.

Any help on resolving this issue would be appreciated.

You seem to be mixing up things. H264 is video compression, AAC is audio compression. ffmpeg is clearly telling you that AAC is disabled.

Please show the output of
Code: Select all
rpm -qa|grep -iE "ffmpeg|avcodec|avformat|aac"|sort
urpmq --list-media active --list-url

AFAICT you have neither the tainted version for ffmpeg and its dependencies installed, and you're also missing the actual AAC encoder, which is lib64vo-aacenc0

Try the following as root:
Code: Select all
urpmi lib64vo-aacenc0
urpmi --auto-update

The latter should update all installed packages to their tainted versions.

That did not fix the issues. Kdenlive still reports that MP4 is missing libx264. Ffmpeg errs out in the same way.

It looks like from the ffmpeg configuration comment that the aac encoder was disabled in the build. Is there a different version in the tainted repos?

Yes.

The bug report describes what I am seeing with kdenlive. It appears that the tainted version of ffmpeg fixed the issue for them.

I opened the MCC and saw only one ffmpeg, which is installed. I do have the tainted repos enabled. How do I get access to the tainted version.. reference the full name of the package mentioned in the report, ffmpeg-4.1.6-1.mga7.tainted.x86_64?

Have a look here=> https://bugs.mageia.org/show_bug.cgi?id=26917

the advisory committed to svn for ffmpeg mistakenly excluded ffmpeg-4.1.6-1.mga7.tainted.
the packaging error has now been corrected.

Please wait a day or so for your locallest mirror to update, then you should be advised of an available update.

Thanks for the info. I will give it a few days, and if the updates fix the issue I will come back and mark the thread solved.

The updates for ffmpeg just showed up. I installed them. Everything works now.

Thanks for all the help.
