mmal_component_create_core: could not find component 'vc.ril.camera'

[Abu-Abdullah]

Hi,

I'm getting this error:
mmal_component_create_core: could not find component 'vc.ril.camera'

env:
ubuntu_mate 16.04
RPI 3

command:
./test-launch "( rpicamsrc bitrate=1000000 ! rtph264pay config-interval=1 name=pay0 pt=96 )"

[thaytan]

I think this means you haven't enabled the camera in /boot/config.txt or else it's not connected correctly. Does it work in raspivid?

[Abu-Abdullah]

yes, it is working normally

[Abu-Abdullah]

i tried on Raspian (latest image) as well the following:
./test-launch "( rpicamsrc bitrate=1000000 ! rtph264pay config-interval=1 name=pay0 pt=96 )"

and it throws:
(lt-test-launch:1044): GStreamer-CRITICAL **: gst_structure_fixate_field_nearest_int: assertion 'gst_structure_has_field (structure, field_name)' failed

(lt-test-launch:1044): GStreamer-CRITICAL **: gst_structure_fixate_field_nearest_fraction: assertion 'gst_structure_has_field (structure, field_name)' failed

** (lt-test-launch:1044): WARNING **: Unknown profile string in rpicamsrc caps: constrained-baseline

I can fix the fixation warnings to do something more sensible in that case, but what it's really complaining about is that you haven't put any caps filter in to tell rpicamsrc which width/height you want it to configure the camera for.

Try something like rpicamsrc bitrate=1000000 ! video/x-h264,width=800,height=600 ! rtph264pay config-interval=1 name=pay0 pt=96

[Abu-Abdullah]

ok now the messages disappear but still im still not able to play the stream.

mplayer (on windows) gives me something like:
rtsp: read error.
librtsp: server responds: 'P�RTSP/1.0 503 Service Unavailable'
STREAM_LIVE555, URL: rtsp://192.168.1.5:8554/test
Failed to get a SDP description from URL "rtsp://192.168.1.5:8554/test": 503 Service Unavailable

VLC gives me:
access_realrtsp warning: Cseq mismatch, got 1, assumed 0
access_realrtsp warning: only real/helix rtsp servers supported for now
core error: open of `rtsp://192.168.1.5:8554/test' failed

[thaytan]

Try running test-launch with GST_DEBUG=3 and see if it spits out any errors / warnings when you try and connect.

In case it helps, I use a pipeline like this for streaming:

rpicamsrc bitrate=750000 intra-refresh-type=both drc=medium ! video/x-h264,profile=baseline,width=640,height=480 ! h264parse config-interval=1 ! rtph264pay name=pay0 pt=96

[Abu-Abdullah]

much appreciated, your pipeline worked with me on raspian. few comments:

• it is only working on raspian, ubuntu mate still has the same issue i.e. i got this message:
  mmal: mmal_component_create_core: could not find component 'vc.ril.camera'

camera is enabled and i can see it.

• in raspian, stream is only limited to one request/player i.e. if i start mplayer and vlc at the same time i got the following:
  mmal: mmal_vc_component_enable: failed to enable component: ENOSPC

I don't know what that is. It sounds like the camera setup is broken
outside of rpicamsrc in Ubuntu MATE, but I don't know why:

camera is enabled and i can see it.

That's surprising - because gst-rpicamsrc is a ported version of
raspivid. Perhaps they modified something and modified raspivid accordingly.

You need to modify test-launch (or use your own small app) and be sure
to set gst_rtsp_media_factory_set_shared (factory, TRUE); (see some of
the other files in the examples dir that do that)

thanks for your support. at least i have a working code in raspian. i will check how to modify test-launch

great support. much appreciated

[Abu-Abdullah]

maybe the issue with ubuntu mate is related to the same as of #28
mmal: mmal_component_create_core: could not find component 'vc.ril.camera'

I got same problem in same environment (Rpi3, Ubuntu 16.04, Gstreamer 1.12).
Did you solve the problem ? @Abu-Abdullah

On my Rpi3, raspivid work correctly. Also the Gstreamer works well with USB web cam.
Only rpicamsrc does'nt work.

I did ldd to libgstrpicamsrc.so and got the message as bellow.

$ldd libgstrpicamsrc.so | grep mmal
        libmmal_core.so => /opt/vc/lib/libmmal_core.so (0x76c4c000)
        libmmal_util.so => /opt/vc/lib/libmmal_util.so (0x76c2b000)

It seems libmmal_core.so and libmmal_util.so are correct but libmmal_vc_client.so is not linked.
The file libmmal_vc_client.so is exist in the path correctly.

So, I added LDFLAGS="-Wl,-O1 -Wl,--hash-style=gnu" befor autogen as the link https://lists.yoctoproject.org/pipermail/yocto/2014-June/019933.html. Also, I tried to add LDFLAGS='-Wl,--no-as-needed'.
But anyway, output .so file seems same and doesn't work.

[thaytan]

what's the output from make V=1 ? Is something pulling in -Wl,--as-needed ?

[ghost]

Did that lead to anything? Having exactly the same problem

Build and install fine
