Maybe it is easier if you just use the pre-build plugins that are part of the package.

Follow section 7.1 (Using the pre-built Plugins) of the release notes document:

- Copy all the content of fsl_codecs/libs to ../rootfs/home in the i.MX27 file system
- Boot Linux on the i.MX27
- Set the following variables on the i.MX27ADS Linux:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/codec:/home/parser
export GST_PLUGIN_PATH=$GST_PLUGIN_PATH:/home/plugin

After doing this, gst-inspect | grep mfw should list 6 elements.

Which BSP version are you using? I suggest you to use the latest MX27 BSP (20071219) and the latest Gstreamer package for MX27 ( http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=IMX27_CODECS&nodeId=02XPgQ82172973ZrDR&fpsp=1&tab=Design_Tools_Tab )

Then click on MX27_FULL_VPU_SW_LINUX_REL3_BSP. It was posted last week.

You can also download the MX27_TEST_STREAMS file from this website.

mfw_vpudecoder is capable of decoding H264 and MPEG4. I don't see any demuxer in your list (such as mfw_avidemuxer). Remember that I mentioned that gst-inspect | grep mfw should return 6 elements. 

Use the following command line for playing an AVI file (with H264 video and MP3 audio):

gst-launch filesrc location=test.avi ! mfw_avidemuxer name=demux demux. !
mfw_vpudecoder codec-type=std_avc ! mfw_v4lsink demux. ! queue maxsize-
buffers=0 ! mad ! alsasink


MP4(MPEG4+MP3):

gst-launch filesrc location=test.mp4 ! mfw_mp4demuxer name=demux
demux. ! mfw_vpudecoder codec-type=std_mpeg4 ! mfw_v4lsink demux. !
queue max-size-buffers=0 ! mad ! alsasink

This is part of the Release Notes and I have mentioned that for you a couple of times. Have you read it?

You should enter a service request in Freescale's website: http://www.freescale.com/support

Fabio Estevam

Can you post your complete Gstreamer pipeline and the error message?

Also, what video format are you trying to decode?
