Hallo!
I encoded mjpeg avis with mencoder (lavc) for playing them in Gem. The strange thing is, that when I play those avis in e.g. vlc or mplayer they look really good ... when I play them in Gem with pix_video the quality is much more worse ... (you can see that the jpeg compression is really bad ...)
Does anyone have an idea what the problem could be ? Do players like vlc, mplayer, ... use additional filters to give better results ?
Thanks for any hints, LG Georg

it turned out that the problem was a badly configured X-server (set to a depthof 16bit!) Gem defaults to 24bit-depth; if it fails to get 24bits, it will fall back to 8bit, which usually is _bad_ quality!
the other players obviously could make better use of the 16bit depth, that is why they looked better.
so for all of you, who experience bad image quality: read carefully what Gem says on the console! there might be a hint, saying "Only using 8 color bits"; make sure that you set the default colour depth to 24bit (or higher)

Hi All,
I'm working on installing the Pure Data Repository Project for the
purposes of showing an Intro to Computer Music Class some of the
advanced capabilities of PD. I'm sure I would have no difficulties
installing the executable and the lib for a command-line version of
PD (I believe it's running on the Linux machine for the advanced
class), but I'm afraid everything we're doing so far has been with
the clickable application on a Mac. I don't want to throw the
Terminal into the mix for the last of 3 classes that deal with PD --
I think it will just turn them off to it. Has anyone used the
project with Hans's Mac builds, RC-6, for example? I'm not sure how
the pointers/aliases work within the apps - nor where I should copy
the executable and the lib to. For once, I'm more sure of how to
install something for Linux than I am for OS X. Bizarre.
Many thanks for help.

If you mean the extended Pure Data help files+documentation, I think it's already included in HC's installers. If it's not that, can you give a link to what you mean?

No, It's not the documentation. There's a description of the project
and links to the files from the following link.
http://www-crca.ucsd.edu/~msp/pdrp/latest/doc/
I've installed everything as per instructions on the page above, in /
usr/local/bin and /usr/local/lib -- and altered the local-settings.sh
file to point to the executable in the app itself -- /Applications/PD/
Pd-0.38.4-RC-4/Content/Macos/Pd.
This works to open the app, but the problem I've had with the Mac app
is that it doesn't remember the sound settings. Also, the above
project is designed to supply sound settings, channels, etc. to match
the needs of the pieces individually and automatically set your I/O
to match. This is the part that doesn't work. Everytime the app
opens, it opens with defaults -- sometimes the patches themselves
open, sometimes they do not.

Somehow I missed this the first time around... I hope to find a better mechanism in the future (letting patches declare their path and audio setup needs) but for now there's no better solution than to make a ".command" file corresponding to each patch. An example might look like:
/Applications/Pd.app/Contents/Resources/bin/pd -path [....]
