First of all you should really upgrade to version 0.7.7.1 (version 0.7.3 is deprecated, there have been a lot of bug fixes since it's release).

On ubuntu 9.10 simply open a terminal and type : sudo add-apt-repository ppa:sunab/ppa

Then update the repos and upgrade (sudo apt-get update ; sudo apt-get upgrade).

It should update Kdenlive and MLT. Then check to see if the problem is still there.



Concerning your issue with Realmedi encoding, could you give the steps in details to reproduce ? For instance what exact codec settings you used.

Shalom and many thanks.
I did update to Kdenlive
Version 0.7.7.1
Using KDE 4.3.5 (KDE 4.3.5).
Thanks for the advice. I noticed great progress in the development of this program's. Two years ago it was just a demo and constantly breaks.
After the upgrade, I was able to rendering all formats except h264 and realmedia/ Flash and Theora did not work before.
H264 is not available. Realmedia - the same problem.
My steps:
open kdenlive
add slideshow
rendering clip to any rm format "vcodec=rv20 acodec=ac3 minrate=0 b=12000k ab=384k ar=48000 s=720x576 g=8"
End is the same/
it looks working fine< but i cant open rm file

So you says h264 and RM profiles aren't available in the render window ?

Well, first of all, are the codecs listed in the "available codecs" in the Kdenlive config wizard ? (You can get to the config wizard from one of the menus) They might be available for decoding but not encoding...

You should also check typing these three commands "ffmpeg -i", "ffmpeg -formats" and "ffmpeg -codecs" in a console. That will give all info about ffmpeg.


Finally try opening a realmedia file with ffplay (ffplay [patch to the file]) and with melt (melt is a video player using the mlt framework.

Can you render any working rm by kdenlive?

I tested and either rv20 encoding fails or ffmpeg can't read it. I only get the audio.

I tried with rv10, and it's the same results, but i downloaded a sample rv10 file and it is read allright.

Apparently it's a problem with ffmpeg encoding of realmedia codecs, you should probably seek answer from the ffmpeg team directly.

Shalom.
I got same success.
If I force progressive and DO NOT export audio it provide playable RM file/
BUT IF I EXPORT AUDIO REALPLAYER indicate general error with this file.
It seems like we got problems with audio settings.
