it's so old, it's just a mistake.
although to tell which codecs are supported is a mistake, cause it depends on your libquicktime installation.
the compressed headers is still true.

Actually, straight from your website:
pdp_yqt : a quicktime movie reader.
Alike pdp_qt, but with less functionnalities, this object reads Quicktime movies. It supports files coded with the following codecs : jpeg, yuv2, divx, dv, yuv2. The files shouldn't have compressed headers neither.
ciao! d.

Hi Yves,
descriptions may be a bit out of date, but when I made them I copied them directly from your website text! ;-) I'll make sure to update them.
best, d.

err, excuse me, what is there more about pidip here than there : http://ydegoyon.free.fr/pidip.html ??
except the erroneous :
pdp_yqt a quicktime movie reader with less functionnalities pdp_qt but with less functionnalities codecs : jpeg, yuv2, divx, dv, yuv2
pdp_yqt can read the sound when pdp_qt export it to a table, they are different yes, but none is "less" than the other.

Hi,
I would like to start with pdp and pidip. Is there any manual or list objects?
Documentation is scarce, almost non-existent in fact besides the sometimes-helpful helpfiles that come with the objects. Here's a list, which I've included in the FLOSS Manual for PD that I'm working on.
Good luck! d.

PDP
This is a list of all pdp objects and abstractions with a minimal description. Take a look at the patches in the doc/ directory for more info. (Messy doc & test patches can be found in the test/ directory.)
general purpose pdp modules:
pdp_del a packet delay line pdp_reg a packet register pdp_snap takes a snapshot of a packet stream pdp_trigger similar to pd's trigger object pdp_route routes a packet to a specific outlet pdp_loop a packet loop sampler (packet array) pdp_description output a symbol describing the packet type pdp_convert convert between packet types
image inputs/outputs:
pdp_xv displays images using the xvideo extension pdp_glx displays images using opengl pdp_v4l reads images from a video4linux device pdp_qt reads quicktime movies
