I installed this and a number of other packages "standalone" ( (as in I
don't have ccrma in my yum repos as it introduces an incompatible version of
jack -- I'm using a stock kernel w/ realtime settings enabled via
permissions for jack/alsa/etc). I just do "yum install
http://ccrma.stanford.edu/planetccrma/mirror/fedora/linux/planetccrma/12/x86_64/xjadeo-0.4.7-1.svn200.fc12.ccrma.x86_64.rpm"
and install whatever other ccrma rpms needed when it can't resolve from the
stock fedora/updates/rpmfusion repos...

With that caveat in place, I just wanted to let you know that I've "tested"
f12 x86_64 xjadeo as "works for me," though I have a question about audio
output.

I actually used qjadeo, the package includes this GUI front-end to xjadeo
and adds it to applications->sound&video menu. IMHO when using qjadeo, the
syncing option should be set to "continuous" as the default option results
in jerky video until you figure this out. It's pretty cool and I'm happy to
have found out about it through this list (thanks Peiman for bringing it
up).

And finding xjinfo is fortuitous, as I was looking for a multiformat video
file information extraction tool -- this one fits the bill perfectly as it
uses XML, which I can snarfle back into groovy (jvm lang) scripts for use in
my java-based web-app. xjinfo outputs info like:

>   <audio>Audio: wmav2, 32000 Hz, 2 channels, s16, 32 kb/s</audio>

  <video>Video: wmv2, yuv420p, 640x480, 1016 kb/s</video>

  <video>Video: vp6f, yuv420p, 200x110, 190 kb/s</video>

  <audio>Audio: mp3, 44100 Hz, 1 channels, s16, 64 kb/s</audio>


Question: I guess xjadeo does what its description says, however, what
happens to the audio in the video? I see no audio outputs created in
qjackctl or patchage, and I didn't notice options for enabling audio output
from the video.

Description: Xjadeo is a very simple video player that gets sync from jack.
