"cannot connect to jack server"...?

[reality1234]

I am trying to convert some .avi-files to VCD, but it´s going very well with the latest version of ffmpegx(h). I´ve done this several times before, but it´s not working anymore.

Here´s the message I get when I start encoding:

Encoding started on Sun May 16 16:52:56 CEST 2004

....

What´s going on?

Output #0, rawvideo, to '/Volumes/Data/.mpv':

Seems like you didn't give a valid name for the output file.

I did name it right, but something very strange is going on with the naming. I just gave the output file the default name "movie" - but in the transcript (see below) it ends up being called "m.mpv"...

...so I don´t think the naming itself is the problem.

ffmpegx starts outputting to the file "m.mpv", but when I try to preview it I just get a black square.

I´ve also tried re-installing both ffmpegx and the engines files, and I´ve tried several different .avi-files - but nothing works.

I´m lost...

...one more thing: I cancelled the processing of the "m.mpv"-file after about 25% was completed. The resulting file is 1.6MB, though claiming to contain 35 minutes of video (I used the default VCD-preset)...that can´t be right?

Is there any way I can get hold of older versions of ffmpegx?

And what does that "jack server"-thing mean?

Thanks for your help!

Something seem wrong in your OSX install. Try "VCD" preset instead of "fast VCD".

And what does that "jack server"-thing mean?

http://www.jackosx.com/about.html, but it is not installed by ffmpegX.

[reality1234]

But why is ffmpegx calling upon the jack server?

Or is it?

...and why aren´t my VCDs being encoded properly (as you can see from the transcript, ffmpegx can´t find either duration or bitrate from the input file etc.)?

Hope you can help.

Or is it?

It is not.

can´t find either duration or bitrate from the input file etc.)?

That warning is harmless.

Hope you can help.

I would suggest to start a fresh OSX in another disk and install ffmpegX there. Then open your AVI file and choose VCD preset, hit encode, and wait for completion.
