SDK version is 1.7.0

kjkh commented 6 years ago

Hi @xuqifu,

Can you check that you have the audioconvert element installed? gst-inspect-1.0 | grep audioconvert

We have not tested with GStreamer 1.9.1, but the release notes mark the 1.9 series as unstable. If it's convenient to upgrade to a more stable version, 1.10.4 for example, it may resolve the issue as well as future problems.

xuqifu commented 6 years ago

hi @kjkh print"audioconvert: audioconvert: Audio converter" when run cmd gst-inspect-1.0 | grep audioconvert on ubuntu for installed platform

xuqifu commented 6 years ago

hi @kjkh i have upgrade GStreamer version to 1.10.4, but appear same error

there's same problem: https://github.com/alexa/avs-device-sdk/643

kclchan commented 6 years ago

Hi @xuqifu, please note that your issue is not exactly the same as #643 because in that issue, it failed because of createAudioSinkElementFailed, while you are failing createConverterElementFailed.

Since converter is the first element created in the pipeline, I suspect the issue lies in your gstreamer installation/configuration.

Could you try this command: gst-launch-1.0 -m audiotestsrc ! autoaudiosink And see if you can hear a test tone?

Hi @xuqifu,

Could you do the below command to double check the version of gstreamer:

gst-device-monitor-1.0 --version

Unfortunately, this seems to be a gstreamer related issue and I do not know how to debug further except to suggest trying to reinstall gstreamer again...

Thanks, Kenneth

xuqifu commented 6 years ago

hi @kclchan I'm trying this command: gst-launch-1.0 -m audiotestsrc ! autoaudiosink And hear a test tone

celinval commented 6 years ago

Hi @xuqifu,

Can you please test the following test instead:

gst-launch-1.0 audiotestsrc ! audioconvert ! autoaudiosink

Thanks

xuqifu commented 6 years ago

hi@celinval

I'm trying following command: gst-launch-1.0 audiotestsrc ! audioconvert ! autoaudiosink device mic make a long sound and print following log: Setting pipeline to PAUSED ... Pipeline is PREROLLING ... Redistribute latency... Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstPulseSinkClock

Thanks

celinval commented 6 years ago

Sorry, @xuqifu,

I forgot the '-m' in the command above. It should be

gst-launch-1.0 -m audiotestsrc ! audioconvert ! autoaudiosink

Can you also please double check that you are using the same gstreamer installation for your tests and to build the sdk? For that, please run:

gst-launch-1.0 --version
type gst-launch-1.0
ldconfig -p | grep gstbase

Are those the same libraries that you are using the build the sdk?

@preth-2018

try following command: gst-inspect-1.0 or you can listening a long sound that try following :
gst-launch-1.0 -m audiotestsrc ! audioconvert ! autoaudiosink

hidori commented 6 years ago

@preth-2018 .asoundrc is configuration file of ALSA. (ALSA is a one of the auduio input/output subsystem of linux)

I think the following issue is causes by invalid audio configuration.

2018-07-31 06:52:49.847 [ 1] 9 MediaPlayer:createCalled
2018-07-31 06:52:50.186 [ 1] E MediaPlayer:setupPipelineFailed:reason=createConverterElementFailed

2018-07-31 06:52:50.194 [ 1] 9 MediaPlayer:~MediaPlayerCalled

SampleApp is running with root privilege. So, You should configure root's ALSA properly. (/root/.asoundrc file)

The sample .asoundrc is

pcm.!default {
  type asym
    playback.pcm {
      type plug
      slave.pcm "hw:1,0"
    }
    capture.pcm {
      type plug
      slave.pcm "hw:0,0"
    }
}

"hw:x,y" of the above, x is card number and y is device number.

You can know the card number and the device number by aplay -l and arecord -l commands.

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]
  Subdevices: 7/7
  Subdevice #0: subdevice #0
  Subdevice #1: subdevice #1
  Subdevice #2: subdevice #2
  Subdevice #3: subdevice #3
  Subdevice #4: subdevice #4
  Subdevice #5: subdevice #5
  Subdevice #6: subdevice #6
card 1: ALSA [bcm2835 ALSA], device 1: bcm2835 ALSA [bcm2835 IEC958/HDMI]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: CD04 [CD04], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Although the above is a story with raspbian, I think that also with arm-linux.

@preth-2018 may be you need to reinstall gst

preth-2018 commented 6 years ago

@xuqifu I found a solution from here(https://github.com/mavlink/qgroundcontrol/issues/4303) and now able to hear a long beep sound. Some plugins were not installed in linux i guess.

list=$(apt-cache --names-only search ^gstreamer1.0-* | awk '{ print $1 }' | grep -v gstreamer1.0-hybris) sudo apt-get install $list

But when running Sample App the issue is still there.

@xuqifu

Did you do the above check's mentioned in ubuntu or emulator? I'm doing these in ubuntu. In emulator I don't have the gst-inspect-1.0.

xuqifu commented 6 years ago

@preth-2018 ubuntu and arm platform I have install gstreamer and gst-inspect-1.0 path at gstreamer/usr/bin

preth-2018 commented 6 years ago

@xuqifu For arm did you cross-compile only the gstremer or all the plugins as well? I used the android binaries available from the site https://gstreamer.freedesktop.org/pkg/android/1.8.0 and merged to my include and lib folders.gst-inspect-1.0 is not there. I only have the libraries like libgstaudioconvert.a. Is that enough in board?

xuqifu commented 6 years ago

you are from china? if so , we can add wechat with each other

preth-2018 commented 6 years ago

@xuqifu I'm Sorry, I'm not from china. Thank you for your quick response.It's very helpful.

xuqifu commented 6 years ago

@preth-2018 I have cross-compile gstremer and all plugins on arm-linux platform by ./configure , so gst-inspect-1.0 exist.

preth-2018 commented 6 years ago

@xuqifu Okay. Thank You. I will also try that then.

Hi @xuqifu, Did your error got resolved? I am also trying to run on ARM platform itself. I am facing similar error. Can you guide me on this.

shenhuaz commented 5 years ago

Hi @avp24 , I meet the same error with you, have you solve this problem?

Thanks!

avp24 commented 5 years ago

@shenhuaz for me this problem got solved by adding environment variables for location of all gstreamer libs.

ankitsablok89 commented 2 years ago

I met the same error but on Apple M1 MAC. Has anyone been able to solve this problem for M1 MAC?
