#18 Can't find pipe

[Anonymous]

I installed the mpeg2enc and ppmtoy4m files
inside /usr/local/bin

However, when I try and use them inside
MediaPipe it says "Error while opening Pipeline.
Pipe not found." Then the program crashes.

I have attached my MediaPipe config file incase
that helps.

I don't see the attached MediaPipe config file, could you
repost it?

"Pipe Not Found" is when the pipeline file requires a
pipe that you do not have loaded/installed. I
understand that this pipeline file involves the
MPEGEncoder pipe - do you see it in MediaPipe when
you open the application (i.e. does it load in the pipe
list?)

Hmm. I thought I uploaded it.

enterprise.1x18.cfg

Yes. It is listed in the left column. There is both an
MPEG Encoder and a Decoder, but the encoder is
dimmed.

The configuration file loads with no problem on my
side...

Can you verify that you have the following pipes in your
pipe list?

"QuickTime Decoder"
"Crop & Scale"
"Change Frame Rate"
"MPEG Encoder"

And if you have those four, could you build a pipeline
manually with them (in the same order listed), save the
pipeline and send me the file?

I choose a Quicktime movie in DV format. its a little
under 9GB in size.

As soon as I click start, the progress menu drops
down, stays for about 1/2 a sec, then the program
crashes.

The Crop&Scale has been identified as a trouble
maker. Could you try the same pipeline without the
Crop&Scale pipe to see if you still experience crashes?

Done. Still crashes.

What exactly does the 'Quicktime Decoder' do to a
Quicktime DV file?

Are there some command line things you would like
me to do? Perhaps run this in gdb or get a core file?

The QuickTime decoder should be capable of
decoding any video that the QuickTime Player can
open...

From your screenshot, I notice that you are still using
0.7.5... did you try with MediaPipe 0.7.6?

Downloaded newest version. I followed the quick setup
in the readme file. I did exactly what it said. Once I
clicked start, the progress plane appeared for about 1/2
second, then went away. It created a new file 1 frame
long composed of the upper-left 1/4 corner of the
original movie.

Anything else you'd like me to try?

Could you take the first minute of your DV clip, copy
paste it in anoter clip, save-as (make sure it's self
contained).

Then try that 1 sec clip to see if you experience the
same problems, and if so, please send me that clip (it
it seems to large for sourceforge, email me and I'll let
you upload directly to my machine)

Thanks =)

Allright. Email me: drmac@cs.utexas.edu
with the account info and I will upload it.
