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

[Favor T. <ta...@gm...>]

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@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@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@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@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@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 ~~~~~~~

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.

hi.

stefan: I dont use x server. thanks for you reminded me. I know why
the xv output error is occurred. cause I dont get x-server support on
my console image.  I should use TIDmaiVideoSink, is that right?

Luther: I follow your instructions, I think I am not far away from
success. But I need more help.
when I play a video file like below, I got errors from mmcblk0 error.
I don't know why?
it just show a small rectangle with a TI brand mark on the right top
of it, except that, It didnt' show any thing.
instead, it  hanged by the error.

any suggestions?
thanks

[Favor T. <ta...@gm...>]

hi. Brijesh

I want to tell you the result of the dsplink test today, and I would
like you give me some proposals.
1)  I changed the bootargs, added the mem=88M.

I have see "New beagleboard demo image, now with 100% more DSP " at
google groups mailing list.
   https://groups.google.com/group/beagleboard/browse_thread/thread/a88dccbb7acc06c?pli=1

I set the loadmodule.sh file as follow:
modprobe cmemk phys_start=0x85800000 phys_end=0x86800000
pools=20x4096,8x131072,4x829440,1x5250000,1x1429440,1x256000
# insert DSP/BIOS Link driver
modprobe dsplinkk
# make /dev/dsplink
rm -f /dev/dsplink
mknod /dev/dsplink c `awk "\\$2==\"dsplink\" {print \\$1}" /proc/devices` 0
# insert Local Power Manager driver
modprobe lpm_omap3530
# insert sdma module
modprobe sdmak

2) load modules ok
root@beagleboard:~# ./loadmodule.sh
ioremap_nocache(0x85800000, 16777216)=0xc8000000
allocated heap buffer 0xc8000000 of size 0x522000
cmem initialized 6 pools between 0x85800000 and 0x86800000
DSPLINK Module (1.60) created on Date: Apr  8 2009 Time: 10:39:08

3) the first time, I use this command for playing mp4 video. this
time, an error is happened without any video display, but I could hear
its sound. with the same command, the second time, it can play this
mp4 video as normal, but with some "mmcblk0: error -84 transferring
data" errors.
except for that, it didn't play to its end of the video, and be hanged
after many(maybe fewer than 60 seconds) seconds.  the video playing
don't  go on, and stop at any point. I am confused why is this
happened.
I have read that thread, but still didn't know how to deal with this.

it seems that the gst-ti plugin and its TI codec combos is not robust
enough, is it? maybe I am wrong, please correct me.

test result: I can see the video display and the sound as well. but
only can play few seconds, and hang.
except for that, an "end_request: I/O error" shows out.

4) I test another video with the same command, this time it can't play
anything at all, instead, CMEMK Error is happened. it seems it is the
cmem modprobe and mem of bootargs problem, but the previous test show
that I can use these arguments to play video, even though, few seconds
(20~35s). any ideas, why?

first remove this element and report a bug against ti, they mispackages it.

I don't see any error. it seems to work as far as gstreamer is concerned.

Do you run a xserver? does it support xvideo? (get yourself xvinfo from
x11-tools).

Could you try to rerun those commands but using
/usr/share/ti-codec-engine as workdir ?
There was a bug in gstreamer that required that, it is said it was
corrected but maybe your version still has it.

dsnk
