IGEPv2 with TI DSP codecs and GStreamer

IGEPv2 with TI DSP codecs and GStreamer

[Andrea]

Hi Enric,
I'm working on two IGEPv2 boards we bought through the university of
Urbino (italy). We were able to run the DSP TI codecs on a BeagleBoard
sample with the 2.6.29 kernel from openembedded. But we still have
some problems with the IGEP boards.

What are the differences between your patched kernel and the one
mentioned above (recipes/linux/linux-omap_2.6.29.bb)?
Which DSS patches have been applied?
Should gstreamer and the DSP TI codecs work as far as you know? Is
there some guide to make it all work or are you still working on it?

The boot parameters we're using are as following:
bootargs-base=console=ttyS2,115200n8 console=tty0
omapfb.mode=dvi:dvi:800x600MR-24@60 mem=99M omapfb.vram=0:3M,1:3M,2:3M
omapfb.debug=y

We have patched the ti-dmai to support the IGEP board and we are
currently using a gstreamer pipe like this:
gst-launch filesrc location=/home/root/bak/video/luce.flv !
ffdemux_flv name=d d.video_00 ! TIViddec2 ! TIDmaiVideoSink
It works, but the video playback is very chunky and instable.

Hi,

you could try the gst-dsp stuff too. I didnt look at the repos, but I think
it isnt in oe yet. trx google search for gst-dsp beagleboard.

Bye Henning

Gst-dsp requires dsp-bridge which we don't (want to) support in OE. It 
is mimicing the gstreamer-ti design, for which we do have working, 
supported recipes in OE.

Hi Andrea,

We are waiting if our patches for the IGEP v2 board are published on
the development branch of Open Embedded to be able better support.
Meanwhile, please ask your questions to

  http://www.myigep.com/forum

Actually, we are working with DSP TI codecs without problems but not
using Open Embedded infrastructure (or the same version as Open
Embedded uses). We intend within a short period of time
work on this.

Regards,

   Enric

I have them queued on a local branch together with some fixed I need to 
test before pushing them out.
You might have noticed the patchwork status of your patches has been 
updated :)

Could you add support for IGEPv2 in dmai?
I patched /recipes/ti/ti-dmai/touchbook-support.patch, but I don't
think is the right place!

I had the same diff locally :) I've also alerted upstream about it and 
both touchbook and igep should be in soon.
