    I used to use a program in Windows called Videoredo. Basically it's a simple, easy to use video editor that can cut out adverts in DVB MPEG streams that I record on my Hauppauge card.

    I didn't think I'd find an equivalent in Linux, but today I stumbled upon Avidemux. And as the title of this thread says: It's exactly what I was looking for! :)

    It's very simple to use and can convert to AVI straight after i've finished editing the video

    The only problem is that the video and audio are out of sync. I think this is due to the raw nature of recording DVB streams - the output file doesn't strictly follow MPEG2 standards.

    Anyways, I now need to find a program that can fix my raw MPEG files so the audio and video do sync. I was looking at ProjectX earlier, but it needs compiling from Java source and the instructions are in German! I'll have to find something else

    Yes, and I tried Kino but it didn't like my MPEG streams.

    Anyway, it turns out that I had the appropriate software all along, I just didn't know it!

    Mencoder can encode my MPEG files and make them conform to standards. After encoding they should work properly in Avidemux.

    I was Googling around and came across this helpful resource. It says the command line option to encode my videos is:

    Code:
    $ mencoder -forceidx -lavdopts er=4 -vc ffmpeg12 -of mpeg \
             -oac copy -ovc copy \
             original_ps.mpeg -o cleaned_ps.mpeg
    But is that supposed to be 3 separate commands? Or should I enter it all on the same line / command?

    Thanks

    The memcoder stream fix didn't really do a thorough enough job.

    I copied the DVB recording over to my Windows comp with VideoReDo installed, and ran the MPEG fix on that. Then I copied the file back to my Linux box and it ran perfectly under Avidemux.

    So I can now conclude that all I need is a decent MPEG 'fixer' for Linux.

    As it stands, VideoReDo is the only Windows only program that I am still dependant on. Unfortunately it won't run under WINE - or I can't get it to anyway. I wonder when Wine Doors will finally get released?

    W00t!

    I found instructions for compiling ProjectX in Java - from the most unlikely source. Got my Linux Magazine in the mail (the one with the free Mandy 07 DVD) and it had an artical about Kmediafactory. ProjectX was mentioned with brief instructions.

    The good news is that ProjectX sorts out my DVB streams perfectly. So now I have lost my dependency on Windows (not that i've been using it, aside from my MCSE) :)

    [ot] Unfortunately the Mandriva DVD is not live. I wanted to try it out but I have completely run out of HDD space :( [/ot]

    Look into Mandriva One, it's 2007 live.
