GstAdapter issue

Hi,

I am able to compile and install my plugin successfully. But when I do gst-inspect, I get the following error.

I have included #include <gst/base/gstadapter.h> . any idea?

[…@ramana] gst-inspect aacparse

(gst-inspect-0.10:2546): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstmpegaacparse.so': /usr/lib/gstreamer-0.10/libgstmpegaacparse.so: undefined symbol: gst_adapter_peek

No such element or plugin 'aacparse'

Thanks

Ramana

Re: GstAdapter issue

Hi,
you have to link your plugin against gstbase library to support gstadapter.
You can use `pkg-config --libs gstreamer-base-0.10` to ease the work.

Re: GstAdapter issue

Hi,

I am just confused where to use this ("pkg-config --libs gstreamer-base-0.10") as makefile file is generated by automake.

Should I edit my Makefile.am?

Makefile.am
-----------
# plugindir is set in configure

plugin_LTLIBRARIES = libgstmpegaacparse.la

# for the next set of variables, rename the prefix if you renamed the .la

# sources used to compile this plug-in
libgstmpegaacparse_la_SOURCES = gstmpegaacparse.c parse_aac.c

# flags used to compile this plugin
# we use the GST_LIBS flags because we might be using plug-in libs libgstmpegaacparse_la_CFLAGS = $(GST_BASE_CFLAGS) $(GST_LIBS_CFLAGS) -O2 libgstmpegaacparse_la_LIBADD = $(GST_PLUGINS_BASE_LIBS) $(GST_BASE_LIBS) $(GST_LIBS) libgstmpegaacparse_la_LDFLAGS = $(GST_PLUGIN_LDFLAGS) # headers we need but don't want installed noinst_HEADERS = gstmpegaacparse.h parse_aac.h

Re: GstAdapter issue

Im' not very friend with autotools, but they should do the work for you
through PKG_CHECK_MODULES calls in gst-check.m4 (this calls pkg-config
--libs)
you can refer to gst-plugins-good build for example, if you look at the
content of the common/m4/gst-check.m4 file, you will find

AC_DEFUN([AG_GST_CHECK_GST_BASE],
[
AG_GST_CHECK_MODULES(GST_BASE, gstreamer-base-[$1], [$2],
[GStreamer Base Libraries], [$3])
])

I guess something like this is missing into your own build files to
include link on gstreamer-base-0.10
