0"  statement which  is always present when checking how  ffmpeg is
called form nuvexport. So I meesed with the scripts from nuvexprt and
the SIGFPE went away, but the audio from the mp4 output is out of
sync....

I've pulled the ffmpeg source from atrpms and it installed,&nbsp; But I
cann't find where it installed to so I can configure and build it.&nbsp;
What was the configuration used to build it?

&nbsp;&gt; Chris,
  <br>
&nbsp;&gt;
  <br>
&nbsp;&gt; I'm currently struggling as well with the myth2ipod script.
  <br>
&nbsp;&gt; I took the source-rpm of ffmpeg from atrpms and recompiled ffmpeg
to
  <br>
&nbsp;&gt; assure the aac (codec) is enabled.
  <br>
&nbsp;&gt;
  <br>
&nbsp;&gt; I found that I can convert mpeg2 videos to mp4 (ipod) when
starting
  <br>
&nbsp;&gt; ffmpeg mnually.
  <br>
&nbsp;&gt; (In the meantime, Axel (atrpms) was very helpful and updated the
ffmpeg
  <br>
&nbsp;&gt; package on atrpms with the using the source).
  <br>
&nbsp;&gt;
  <br>
&nbsp;&gt; I tried to nail down my problem when starting "nuvexport -debug".
  <br>
&nbsp;&gt; (nuvexport is called form myth2ipod).
  <br>
&nbsp;&gt; In the debug mode nuvexport provides a list commands executed, so
you
  <br>
&nbsp;&gt; just do the conversion step by step, using two shells.
  <br>
&nbsp;&gt; In my case the error was caused by a SIGFPE (floating point
error),
  <br>
&nbsp;&gt; casued by ffmpeg.....
  <br>
&nbsp;&gt;
  <br>
&nbsp;&gt; I'll investigate a bit further to check if this has to do with
the fifos
  <br>
&nbsp;&gt; created by nuvexport.
  <br>
&nbsp;&gt;
  <br>
&nbsp;&gt; I'm not sure how to get a hold of people coding nuvexport, but
I'll also
  <br>
&nbsp;&gt; post this behavior on the ffmpeg-devel list, because on the end
ffmgeg
  <br>
&nbsp;&gt; falls over the FPE issue...

&nbsp;&gt;&gt; I have a Myth 20 system on a Fedora Core 4 I installed from
the ATRPMS
  <br>
&nbsp;&gt;&gt; following Jerod's guide.
  <br>
&nbsp;&gt;&gt; I've been trying to get myth2ipod to install and run. I've
installed
  <br>
&nbsp;&gt;&gt; myth2ipod but when I execute it the log file says that ffmpeg
exited
  <br>
&nbsp;&gt;&gt; early.
  <br>
&nbsp;&gt;&gt; I suspect I don't have ffmpeg built right. How do I build
ffmpeg with
  <br>
&nbsp;&gt;&gt; the right properties enabled starting from a yum installed
machine.
  <br>
&nbsp;&gt;&gt; I've read Jerod's spec file posted in Dec. but I don't know
what to do
  <br>
&nbsp;&gt;&gt; with this. Any detailed install instructions would be greatly
  <br>
&nbsp;&gt;&gt; appreciated.
  <br>
&nbsp;&gt;&gt;
