Getting playbin plugin works on Gstreamer-0.11.1

[Angel Guzman Maeso]

Hi everyone,

My fist message on this list. 

I am trying to compile Gstreamer-0.11.1 with gst-plugins-base-0.11.1 on Ubuntu Oneiric 11.10 for use Python (PyGi and GTK 3) with playbin plugin.

I know that the old playbin was removed and playbin2 was promoted to playbin.

http://lists.freedesktop.org/archives/gstreamer-devel/2011-August/032588.html

For install Gstreamer 0.11.1 I did:

sudo apt-get install bison flex
wget http://gstreamer.freedesktop.org/src/gstreamer/gstreamer-0.11.1.tar.gz
tar -xvzf gstreamer-*.tar.gz
cd gstreamer-*
./configure --prefix=/usr
sudo make all
sudo make install

Then I try to install gst-plugins-base-0.11.1

wget http://gstreamer.freedesktop.org/src/gst-plugins-base/gst-plugins-base-0.11.1.tar.gz
tar -xvzf gst-plugins-base-*.tar.gz
cd gst-plugins-base-*
./autogen.sh
./configure --prefix=/usr
sudo make all
sudo make install

With 0.10 I get:

$ gst-inspect-0.10 | grep playbin

playback:  playbin: Player Bin

playback:  playbin2: Player Bin 2

But 0.11 ouput nothing

$ gst-inspect-0.11 | grep playbin

it seems that libgstplaybin.so is not generated on 0.11.1:

$ ls /usr/lib/gstreamer-0.10/ | grep play
libgstplaybin.so
libgstreplaygain.so

$ ls /usr/lib/gstreamer-0.11/ | grep play
libgstplayback.la
libgstplayback.so

This works:

$gst-launch-0.10 playbin2 uri=file:///home/user/somefile.ogv

This doesn't work, because the plugin playbin doesn't exist:

$ gst-launch-0.11 playbin uri=file:///home/user/somefile.ogv
ERROR: pipeline could not be constructed: no element "playbin".

On girrepository-1.0 it seems generate the same .typelib files
ls /usr/lib/girepository-1.0/ | grep Gst
Gst-0.10.typelib
Gst-0.11.typelib
GstApp-0.10.typelib

GstTag-0.10.typelib
GstTag-0.11.typelib
GstVideo-0.10.typelib
GstVideo-0.11.typelib

So, what I am doing wrong on 0.11.1 for playbin?

Regards,
Angel

Any response? Please, could someone help me?

On configure file generated shows only this plugins. No mention to playbin or playbin2 (only playback)

GST_PLUGINS_ALL =  adder app audioconvert audiorate audiotestsrc encoding videoconvert gdp playback audioresample subparse tcp typefind videotestsrc videorate videoscale volume

GST_PLUGINS_BASE_CFLAGS = -I$(top_srcdir)/gst-libs -I$(top_builddir)/gst-libs

GST_PLUGINS_DIR = /usr/local/lib/gstreamer-0.11

GST_PLUGINS_NONPORTED = 

GST_PLUGINS_SELECTED =  adder app audioconvert audiorate audiotestsrc encoding videoconvert gdp playback audioresample subparse tcp typefind videotestsrc videorate videoscale volume

On GST_PLUGINS_DIR location, only appears this:

$ ls /usr/local/lib/gstreamer-0.11/libgst

libgstcoreelements.la  libgstcoreelements.so  libgstcoreindexers.la  libgstcoreindexers.so

But for 0.10 I only found this:

$ ls /usr/local/lib/gstreamer-0.10/libgst

libgstpython.la  libgstpython.so

Using the code examples, playbin-text.c fails too:

  App *app = &s_app;

  GstBus *bus;

  GstCaps *subcaps;

  gst_init (&argc, &argv);

  /* create a mainloop to get messages */

  app->loop = g_main_loop_new (NULL, TRUE);

  app->playbin = gst_element_factory_make ("playbin2", NULL);

  g_assert (app->playbin);

did you set GST_PLUGIN_PATH to point to /usr/local/lib/gstreamer-0.11/ ?

Don't. I set /usr as prefix on configure file:

./configure --prefix=/usr

But for some reason the configure generate a bad path for makefiles. But, on that path still is missing the playbin plugin, so, where is generated?
