Hallo!
./make does compile the 3 externals, but fail for the plugins : Dans le fichier inclus à partir de plugins/FileReadGst.cpp:20: plugins/FileReadGst.h:26:32: erreur: gst/app/gstappsink.h : Aucun fichier ou répertoire de ce type plugins/FileReadGst.h:27:34: erreur: gst/app/gstappbuffer.h : Aucun fichier ou répertoire de ce type
and then i've got lot's of error...
(it mean that some include from plugins/FileReadGst.cpp:20: can't be find (gst/app/gstappsink.h and gst/app/gstappbuffer.h).
i don't have the app folder in /usr/include/gstreamer-0.10/gst. this is certainly because i don't have the gstreamer-plugins-bad headers. i have gstreamer-plugins-bad, but i don't have any gstreamer-plugins-bad-dev package. where should i get it?
Yes thats the problem why I haven't released the external yet. You will need the gstreamer-plugins-bad headers and there is no dev package - so you have to download directly the gstreamer source for gstreamer-plugins-bad: http://gstreamer.freedesktop.org/src/
ok. i downloaded the http://gstreamer.freedesktop.org/src/gst-plugins-bad/gst-plugins-bad-0.10.5.... file (as it's the same version that is curently installed on my computer) then : sudo cp -r /home/nusmuk/Desktop/gst-plugins-bad-0.10.5/gst-libs/gst/* /usr/include/gstreamer-0.10/gst/
i now have this only error :
nusmuk@nusmuk:~/pd/videoIO/src$ make g++ -c -Wall -O2 -fPIC -ffast-math -mmmx -I/usr/include/gstreamer-0.10/ -I/usr/include/glib-2.0/ -I/usr/lib/glib-2.0/include/ -I/usr/include/libxml2 plugins/FileReadGst.cpp plugins/FileReadGst.cpp: In member function «virtual int FileReadGst::processFrameData()": plugins/FileReadGst.cpp:198: erreur: «gst_app_sink_pull_preroll" was not declared in this scope make: *** [FileReadGst] Erreur 1
did i miss something?
moreover, i don't understand GLIB_INCLUDE1 and GLIB_INCLUDE2. should they be like : GLIB_INCLUDE1=/usr/include/glib-2.0/gobject/ GLIB_INCLUDE2=/usr/include/glib-2.0/glib/ ?
I have it like this: GLIB_INCLUDE1=/usr/include/glib-2.0 GLIB_INCLUDE2=/usr/lib/glib-2.0/include/ on ubuntu 7.10
ok
for now, this objects crash when i open the helpfile because : No VideoIO Plugin found! Be sure that they are in the right path (/usr/lib/videoIO) !
Yes, that's clear because you have no plugin ...
this "dazzle" device i'm using have 2 input : TV and analog input.
using mplayer i get the analog input with : mplayer -tv driver=v4l2:device=/dev/video0:input=1:width=640:height=480 tv://
while tv input is the same but with input=0
does pix_device_read can select the input 1? (i can't see something like this in the help)
Hm, I haven't tested it ... you can specify the video device during open, but I don't know if this will help you. However, you can change the following propoerties in the gstreamer element (see [1]) - if it's in there you can just add the property.
ok, thanks. i'll have to digg.

I also just realized that we only implemented v4l - but you can change the "v4lsrc" to "v4l2src" in DeviceReadGst.cpp line 321. You can also set additional properties (as in [1]) like done in line 324 in that file.
If this works for you (v4l2) then I will add it also to the videoIO external ...
