Hi all,
Can anybody tell me that the codecs of gstreamer like mad. are
running in DSP or application processor?

The first time you run OpenEmbedded, it will build its own cross-compiler. You should not use scratchbox with OE. See the "getting started" guide at www.openembedded.org. You might be interested in the Angstrom distribution demo image for the beagleboard. Here is the link: http://www.angstrom-distribution.org/beagleboard-demo-image-available Regards, Bjørn Forsman |

Hi Bjorn,
i m am confused with one thing only. I will run g streamer on
beagle board which is having target processor othet than x86. So if i need
to compile g streamer library i need to compile it with the help of cross
compiler. With this i need to cross compile other dependencied also like
glib , liboil, xml etc...
If i follow open embedded link without using scratchbox
application, i can not see anywhere cross compiler options. So to follow
open embedded i must have to install scratchbox tool first thenonly i can
cross compile gstreamer and other dependency.
i was using red hat enterprice linux edition to install
scartchbox2 and gstreamer. But it is ahving older releases of packages. So i
have installed my system with fedora 11 and then i will use all steps
mentioned in open embedded link and also try to install sbox2.
Please correct me if i am wrong at anywhere.
Thanks in Advance,
Tejas.

I'm under the impression that a lot of BeagleBoard owners use
OpenEmbedded (OE) to build gstreamer.
Have you tried OE? (It will compile all of gstreamer's dependencies too.)

Hi, This is the first public release of gst-dsp; a native GStreamer plug-in to access Texas Instruments' DSP algorithms for OMAP3 platforms. The code came originally from a series of TI projects: tiopenmax[1], and libbridge[2]. gst-dsp replaces these two layers and talks directly to the DSP bridge driver. The main advantages are code simplification (5k vs 50k), and better performance (at least 4 times less CPU usage). However, not all of the codecs have been implemented, only MPEG-4 and H.263 video encoders and decoders, the JPEG encoder, and H.264 is partially supported. Currently it's used in the Nokia N900. In order to make it easier for people to try it out, I created a demo image for the beagleboard with all the required components: GStreamer, gst-dsp, DSP public binaries, and a kernel with DSS2 and DSP bridge driver. The linux kernel (DSS2 + dspbridge) is at the v2.6.32-felipec1 tag in: http://gitorious.org/~felipec/linux-omap/felipec The DSP algorithms are public, and come from tiopenmax: https://gforge.ti.com/gf/download/frsrelease/170/1399/tiopenmax-0.3.5.tar.gz Here's the demo rootfs with the kernel image and instructions: http://people.freedesktop.org/~felipec/beagle-2.6.32-rc3/ And here's the video showing it on action for both playback and recording: http://www.youtube.com/watch?v=SN-Nw_yDQUs The main repository is hosted on github: http://github.com/felipec/gst-dsp And there's also one specific for maemo: http://maemo.gitorious.org/maemo-multimedia/gst-dsp This code wouldn't have been possible without all the contributions and specially thanks to TI for making their code open source. Here's the shortlog for 0.6.0: Andriy Shevchenko (1): base: fix a crash on send codec data Felipe Contreras (180): Initial commit Register dsp node Add README Fix and update copyrights Add

Hi all,
I am new to Gstreamer. When the user application makes a call to
the core function like. gst_element_factory_make() then how the
corresponding plugin get loaded..? And how the media stream passes
between the elements?

Hi Felipe,
it's really nice to have your reply back. i have confusion.
If i follow "http://gstreamer.freedesktop.org/wiki/HowToCompileForEmbedded"
link to cross compile gstreamer for my beagle board, there is no CC option
is given to cross compile it. i have already cross tool chain available at
following path on my system.
/root/CodeSourcery/Sourcery_G++/bin/arm-none-linux-gnueabi-gcc/root/CodeSourcery/Sourcery_G++/bin/arm-none-linux-gnueabi-gcc
Can you suggest me in briefly how can i compile gstreamer for
beagle board.
Thanks In Advance,
Tejas.

I also use GStreamer on the beagleboard, it's very easy to cross-compile:
http://gstreamer.freedesktop.org/wiki/HowToCompileForEmbedded
And I use scratchbox, but there are other alternatives:

Hello Felipe,
I am giving following command to configure gstreamer.
1. gsteamer version is 0.10.21
./configure --prefix=/opt/gstreamer_beagle/

By this command i can configure it successfully. But when i give
make command it gives me error like following.

This should not happen. Can you run the with
GST_DEBUG="*:4" gst-inspect 2>debug.log ....

Dear Mike:
I have see the code briefly.
my configure is :
./configure --prefix=/home/felix/gstreamer --disable-aalib --disable-annodex --disable-cairo --disable-cdio --disable-check --disable-dv1394 --disable-esd --disable-examples --disable-failing-tests --disable-flac --disable-gconf --disable-gconftool --disable-gtk-doc --disable-hal --disable-ladspa --disable-libcaca --disable-libdv --disable-nls --disable-oss --disable-shout2 --disable-speex --disable-static --disable-sunaudio --disable-tests --disable-valgrind --disable-x --disable-xshm --enable-jpeg --enable-libpng --enable-shared --without-check ERROR_CFLAGS=\"\" PKG_CONFIG_PATH=/home/felix/gstreamer/lib/pkgconfig PKG_CONFIG_LIBDIR=/home/felix/gstreamer/lib/pkgconfig --enable-gst-debug --enable-debug CC=/home/felix/IntelCE-1.1120/i686-linux-elf/bin/i686-cm-linux-gcc CFLAGS="-I/home/felix/gstreamer/include -I/home/felix/gstreamer/include -I/home/felix/IntelCE-1.1120/i686-linux-elf/include -pg" LDFLAGS="-L/home/felix/gstreamer/lib -L/home/felix/gstreamer/lib -pg"
I find the when the program run to the following instruction the SIGSEGV will appears.
/gst-plugins-good-0.10.14/gst/rtsp/gstrtspsrc.c:line 2118, stream->udpsink[0] = gst_element_make_from_uri (GST_URI_SINK, uri, NULL);
I trace it into gst_element_ake_from_uri and it stop at
/gstreamer-0.10.22/gst/gsturi.c:line 606, if ((ret = gst_element_factory_create (GST_ELEMENT_FACTORY (walk->data), elementname)) != NULL) {
I trace it into gst_element_factory_create and it stop at
/gstreamer-0.10.22/gst/gstelementfactory:line 405, GST_ELEMENT_CAST (g_object_new (factory->type, NULL));
I just run g_object_new (factory->type, NULL) and SIGSEGV appears. The factor->type seems to be valid. Do you have any comment?

You should look at where it crashed in a debugger, and see what the cause was. It could be a bug in a plugin that has since been fixed, or perhaps you've found a new bug. Alternatively, there could be an issue with how you've built gstreamer or dependencies. There's no way for us to know from what you've mentioned.

Dear All:
I have ported gst-plugins-good-0.10.14 on the Intel CE3100 platform. The linux version is 2.6.23.
I can ust gst-inspect to see rtspsrc. However, when I run "gst-launch rtspsrc location=rtsp://192.168.11.167/sd.ts ! fakesink".
The console print Caught SIGSEGV accessing address 0x26
Spinning. Please run 'gdb gst-launch 1220' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.
I didn't chane any problem and I just configured it and make them. What mistake did I make?

That, and I wanted an excuse to teach myself about NEON ;-) So I don't know if you want to integrate this patch as-is, which is why I didn't create an issue in bugzilla yet. I guess my next side- project is to learn a bit more about liboil / orc. > and then some comments on the patch itself: > - Don't use __atribute__(weak), it's not portable.

But I admit that my configure- foo is weak, so there is certainly a better way to do this. > - The start of a buffer might not be 16 byte aligned or what alignment > is required by VFP.

So I guess it could be made a bit faster by handling alignment a little better. As-is, it is a night and day difference and the gstaudioconvert related functions only show up a couple pages down in oprofile output. Now it is liba52 that needs some optimization ;-) > In general this patch is a good idea though, something like this > really > needs to go into audioconvert at critical places for other > architectures > too. > > FYI, David Schleef has partially converted audioconvert to use orc[0]. > Together with the orc VFP backend this would obsolete your patch I > guess. > > [0] http://cgit.freedesktop.org/~ds/gst-plugins-base/log/?h=orc > <signature.asc><ATT00001.txt><ATT00002.txt> [RC] ok, I'll check out his patch.. that is almost certainly the better long term approach. I just didn't know what was the current state of ORC for NEON/VFP.. BR, -R |
