gst-ffmpeg: libgstffmpeg.so cannot be loaded?

Hi, gstreamer-devel:

    I compiled gst-ffmpeg-0.10.5 on my PC with commands listed below:

    ./configure --prefix=/usr --enable-libamr-nb --enable-libfaad --enable-nonfree
    make
    sudo make install

    PS: I installed libamrnb & faad and gst-ffmpeg found them in configure stage.

    After installation finished, I found libgstffmpeg.so cannot be loaded:

eric@eric-desktop:~$ gst-inspect|grep ffdec
(gst-inspect-0.10:23654): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstffmpeg.so': /usr/lib/gstreamer-0.10/libgstffmpeg.so: undefined symbol: Encoder_Interface_exit

    Any ideas? Is this a bug or something is wrong with my configure options? Thanks for any suggestions.

Hi, gstreamer-devel:

Anybody knows this? How do you use ffmpeg to decode amr or aac medias? Thanks in advance.

Re: gst-ffmpeg: libgstffmpeg.so cannot be loaded?

Missing symbol (Encoder_Interface_exit) is in libamrnb.so ...

If you are looking for amr or aac decoders, you can try :
amrnbdec --> gst-plugin-ugly
faad -> gst-plugin-bad

Re: gst-ffmpeg: libgstffmpeg.so cannot be loaded?

Hi, gstreamer-devel:

Thanks, Aurelien. How to fix this issue? I wanna use not only amrnb and aac decoders but also h263p/h264 and other decoders which only exist in ffmpeg. So I need gst-ffmpeg to work.

Compile gst-ffmpeg without using any external library (ie remove the
--enable-libamr-nb --enable-libfaad). These have their own gstreamer
plugin. The default build of gst-ffmpeg should work fine and provide you
with all of the codecs that are part of ffmpeg.
