KmPg2 is a user friendly MPEG2 encoding wizard that enables the user to easily create high quality DVD compatible MPEG2 streams from any input video file.

Creating high quality MPEG2 streams involves a lot more than simply feeding the input video to mpeg2enc/transcode/mencoder/etc. The input video needs to be carefully prepared by pulling it through a chain of stream processing tools like low-pass filters, color correction filters, static and dynamic chroma and luma noise filters, scalers, and so on. This processing chain needs to be tuned in such a way that all irrelevant data (like noise) is removed before the video enters the encoder. KmPg2 uses the video processing / encoding tools from the MJPEGTools project to achieve this.

KmPg2 features a 'profiler' that enables the user to interactively create custom pre-processing pipelines that are optimised for a specific type of video material. These preprocessing pipelines (profiles) can be stored and used with the actual encoding wizard. For example, you could create a profile that is designed especially for restoring a single aging VHS tape, or you could create a profile tuned for your digital camcorder and re-use it for every new recording that needs to be encoded.

 Kmpg2 Not Run

 by Malo on: Jul 7 2007
Score 50%

I've got Archlinux.. I've installed all dependecies and the program starts. But when i choose the file to convertert, an alert says that my ffmpeg version can not decode Ac3 format who is necessary to DVD.. Why this?
I go to the shell and type:

ffmpeg -formats

And I can find in the output

ffmpeg -formats | grep ac3

DE ac3 raw ac3
DEA ac3

My version of ffmpeg is compiled from svn I think (but it's in the arch repository).. Maybe this is the problem?

Also I compiled ffmpeg with liba52 support
but kmpg2 keeps saying that cannot continue because cannot write AC3 sound.

What config params. should be used at ffmpeg compilation time ?

It seems there is a bug that prevent kmpg2 to recognize ac3 in ffmpeg. Got the same with Mandriva 2008.
I found a way out. In YUVdecoder.sh, in the TestAudioEncoding, you must change the value -ab 384 in -ab 384000 and reinstall kmpg2 to pass the ac3 test. FFmpeg cant encode ac3 with a value like 384 b/s, only with value like 384 kb/s.

But i get an error encoding video (**ERROR: [mpeg2enc] Could not read YUV4MPEG2 header: system error (failed read/write)!). Don't know if this is another bug or a sequel of my change in YUVdecoder.sh

My error came from a different version of Y4mscaler and mjpegtools. i recompiled Y4mscaler with the new header and all went fine. so, all is working fine now.
And good new, the "cheat" -ab 384000 works fine. so enjoy this great tool.

Forget to tell that you have to change also the Audiobtirate in YUVMultiplexer.sh to 384000 in order encoding to work.

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
