Hi all,

I've packaged Rygel, a upnp media server and renderer, to use as the
media renderer in the upnp demo. However I'm seeing a segfault at launch
and as it's getting late here I'm wondering if someone in a strategic
timezone can help debug while I cycle home and sleep.

The (ugly) recipes are in the josh/demo branch of the meta-demo
repository.

rygel --gst-debug-level=5

shows plenty of output, but nothing that jumps out to a gstreamer newb
like me. AFAICT I have all of the plugins required but it's possible we
need to add more.

If not I'll pick it up again in the morning.

Thanks,
Joshua

Dongxiao,

Can you take a look at this since you have worked with the gstreamer?

Thanks
Sau!

It seems I didn't push all of my changes, just trying to replicate them
here and push.

so Josh, have you pushed all of your changes now? That way Dongxiao can follow
up with it here.

Thanks
Kevin

I did a sloppy job pushing my changes when leaving the office but think
I have replicated most/all of the in the josh/demo branch.

I also took a look through the rygel code to see what gstreamer elements
are explicitly being used, I've created a list and tried to ensure as
many as possible of them are in the IMAGE_INSTALL list for
poky-image-rygel, adding them to the RDEPENDS for rygel doesn't appear
to have included them in the image I just created...

Full list of names of pipeline elements I found in the rygel code
follows:

decodebin2, videorate, videoscale, ffmpegcolorspace, ffenc_wmv1,
twolame, lame, mp3parse, ffenc_wmav2, convert-sink-pad,
ffenc_mpeg2video, audio-src-pad, audio-sink-pad, audio-enc-sink-pad,
sink, mpegtsmux, audioconvert, audioresample, audiorate, capsfilter,
audiotestsrc, videotestsrc, ffmux_asf

Cheers,
Joshua

Thanks
Sau!

Have all of above elements already enabled in your branch, or is it still
in progress to follow up?

Is it a separate issue from segfault or related in your gut-feeling?

Thanks

The image I just built with my latest changes in josh/demo worked!?!
Rygel did not segfault :-)

If you have time Dongxiao (or anyone else) I'd appreciate if you could
double-check my changes (my install_append in rygel to create a .config
isn't working, so you'll need to do that manually and run
rygel-preferences to disable the tracker plugin).
If you could test using Rygel as a renderer for some content served by
the mediatomb image, that would be much appreciated. You'll want
gupnp-av-cp as provided by gupnp-tools to control the renderer and
content server.

Thanks,

They have now.

Definitely related, rygel launches without segfault now. It doesn't
explicitly specify which elements are required at build time and for at
least some of them doesn't handle them not being there very well at all.

It is my udnerstanding that we plan to run both the renderer and the gupnp-av-cp on each "player". That is an ARM BeagleBoard and a PowerPC *unknown* board. Each will have a suitable display. Is this your understanding/intention?

Also it'd be great if we have a detail list for demo steps. Is it included in the

For testing the images, you can use all x86 hardware. I'd prefer we not use QEMU as it is likely to complicate the networking, which is rather integral to this demo.

Also it'd be great if we have a detail list for demo steps. Is it included in the
demo branch?

No documented steps yet, just build the live images in the demo layers and boot on hardware. If you run into issues, please share them here and we'll help work through them.

I just built out the poky-image-rygel image with your meta-demo layer, and run

rygel --gst-debug-level=5

I still saw it "segmentation fault" in the last...

I am looking into it.

Thanks,

Hi Josh,

Today I took a glance at the rygel crash issue in poky. Though I didn't get the root cause, I found when configure Tracker plugin into rygel, the segmentation fault will happen. Since we have already configured the media-export plugin, and tracker plugin plays the same role, I think we can simply disable tracker plugin (by configure time or change by rygel-preferences) for demo usage.

Yes, I thought I mentioned disabling the tracker plugin in an earlier
mail? I'll prepare a patch to the recipe to disable that so we don't
have to remember to do that by hand.

The image I just built with my latest changes in josh/demo
worked!?! Rygel did not segfault :-)

If you have time Dongxiao (or anyone else) I'd appreciate if you
could double-check my changes (my install_append in rygel to
create a .config isn't working, so you'll need to do that
manually and run rygel-preferences to disable the tracker
plugin). If you could test using Rygel as a renderer for some
content served by the mediatomb image, that would be much
appreciated. You'll want gupnp-av-cp as provided by gupnp-tools
to control the renderer and content server.

Thanks,
Joshua

I will try your branch, however I didn't find josh/demo in
poky-contrib. Is it reside in other place?

It should be here:

ssh://git@.../meta-demo.git

Tom

Got it, thanks!

Hi Josh,

Today I took a glance at the rygel crash issue in poky. Though I
didn't get the root cause, I found when configure Tracker plugin into
rygel, the segmentation fault will happen. Since we have already
configured the media-export plugin, and tracker plugin plays the same
role, I think we can simply disable tracker plugin (by configure time
or change by rygel-preferences) for demo usage.

Yes, I thought I mentioned disabling the tracker plugin in an earlier
mail? I'll prepare a patch to the recipe to disable that so we don't
have to remember to do that by hand.

Ah, oops. I didn't read your previous mail carefully...
But luckily it didn't cost too much time. :-)

Thanks,
Dongxiao

Cheers,
Joshua

Thanks,

I just built out the poky-image-rygel image with your meta-demo
layer, and run

rygel --gst-debug-level=5

I still saw it "segmentation fault" in the last...

I am looking into it.

Thanks,
Dongxiao

Dongxiao,

Can you take a look at this since you have worked with the
gstreamer?

I did a sloppy job pushing my changes when leaving the office
but think I have replicated most/all of the in the josh/demo
branch.

I also took a look through the rygel code to see what gstreamer
elements are explicitly being used, I've created a list and
tried to ensure as many as possible of them are in the
IMAGE_INSTALL list for poky-image-rygel, adding them to the
RDEPENDS for rygel doesn't appear to have included them in the
image I just created...

Full list of names of pipeline elements I found in the rygel
code follows:

decodebin2, videorate, videoscale, ffmpegcolorspace,
ffenc_wmv1, twolame, lame, mp3parse, ffenc_wmav2,
convert-sink-pad, ffenc_mpeg2video, audio-src-pad,
audio-sink-pad, audio-enc-sink-pad, sink, mpegtsmux,
audioconvert, audioresample, audiorate, capsfilter,
audiotestsrc, videotestsrc, ffmux_asf
