[gst-embedded] how to let gstreamer and dsplink to work

[Favor Tang]

Hi. all

    These days I am working on dsplink/gstreamer, I just have  dsplink
worked, also, I have already compiled the gstreamer_ti plugin and
Ti-code-engine worked as well.

    I load dsplink module as below, I think it had been loaded successfully:

root at beagleboard:~#
/usr/share/ti-codec-engine/loadmodules-ti-codec-engine-apps.sh
You have 60324kB total memory for Linux
ioremap_nocache(0x85000000, 16777216)=0xc7000000
allocated heap buffer 0xc7000000 of size 0xea000
cmem initialized 7 pools between 0x85000000 and 0x86000000
DSPLINK Module (1.60) created on Date: Apr  8 2009 Time: 10:39:08

    I can do some dsplink test ( it works), I have the lpm modules
work  as well, for example:

root at beagleboard:/usr/share/dspsample# ./lpmON.x470uC
==== LPM ON Test ====
app: LPM_open
app: LPM_set(LPM_CTRL_REFCOUNTOVR)
app: LPM_on
app: LPM_close
==== All Done ====

root at beagleboard:/usr/share/dspsample# ./lpmOFF.x470uC
==== LPM OFF Test ====
app: LPM_open
app: LPM_set(LPM_CTRL_REFCOUNTOVR)
app: LPM_off
app: LPM_close
==== All Done ====

root at beagleboard:/usr/share/ti-dsplink# ./messagegpp message.out 10000
this works well with some normal messages output.

when I am uising gst-inspect command like below, I got these gst
elements. As we can see, I got gstreamer-ti plugin.

root at beagleboard:~/gstreamer_demo/omap3530# gst-inspect  | grep TI
(gst-inspect-0.10:1663): GStreamer-WARNING **: Failed to load plugin '/usr/lib/g

TICodecPlugin:  TIVidenc1: TI xDM 1.x Video Encoder
ffmpeg:  ffdec_vcr1: FFMPEG ATI VCR1 decoder

however, those all above work well, I still cannot get
gstreamer/dsplink worked together, how and why? any ideas?

First test ~~~~~~~

root at beagleboard:~/mediaFile# gst-launch filesrc
location=/home/root/mediaFile/3.m4v ! qtdemux name=demux
demux.video_00 ! TIViddec2 ! TIDmaiVideoSink
(gst-launch-0.10:1699): GStreamer-WARNING **: Failed to load plugin

Second test~~~~~~~

root at beagleboard:~/mediaFile# gst-launch -v filesrc
location=/home/root/mediaFile/3.m4v ! qtdemux name=demux
demux.video_00 ! TIViddec2 ! xvimagesink

(gst-launch-0.10:1714): GStreamer-WARNING **: Failed to load plugin

I didn’t get any video output on the screen. how should I do to test
if gstreamer/dsplink works? What about above tests errors?

thanks for your attention, any help is welcome.
