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

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

Second test~~~~~~~

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.
