[gst-embedded] gst-ffmpeg cross compile problem

[代坤娟]

Hi,
   i have some problem when i try to cross compile gst-ffmpeg for my arm
board, pls help me.


  i configure gst-ffmpeg as follows:


./configure CC=arm-none-linux-gnueabi-gcc --build=i686-linux
--host=arm-none-linux-gnueabi --prefix=/usr/local/gstreamer
CFLAGS=-I/usr/local/gstreamer/include/ LDFLAGS=-L/usr/local/gstreamer/lib


PKG_CONFIG_PATH=/usr/local/gstreamer/lib/pkgconfig
LD_LIBRARY_PATH=/usr/local/gstreamer/lib

but i get the error saying :


Configuring included FFmpeg instance with args --prefix=/usr/local/gstreamer
--disable-ffserver --disable-ffplay        --enable-postproc --enable-gpl
--enable-static --enable-shared     --disable-encoder=flac
--disable-decoder=cavs --disable-protocols --disable-devices
 --disable-network --disable-hwaccels --enable-cross-compile
--target-os=linux-gnueabi --arch=arm --cross-prefix=arm-none-linux-gnueabi-
--disable-ffmpeg
Unknown OS 'linux-gnueabi'.

If you think configure made a mistake, make sure you are using the latest
version from SVN.  If the latest version fails, report the problem to the
ffmpeg-user at mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.err" produced by configure as this will help
solving the problem.
config.status: error: Failed to configure embedded FFmpeg tree


how should i configure  gst-ffmpeg , pls help me, thanks!


in addition, i want to know if i want to play video on my arm board, what
videosink i can use? when i use autovideosink , the message it displays as
follows:


[root at Real6410 /]# gst-launch filesrc
location=/usr/local/gstreamer/demo/S.avi !
 decodebin ! ffmpegcolorspace ! videoscale ! autovideosink
Setting pipeline to PAUSED ...
