I'm working on VVDN imx6 board I had successfully installed gstreamer on it. After this command:

gst-launch-0.10 audiotestsrc ! audioconvert ! autoaudiosink

I got error:

root@imx6slzbha:~# gst-launch-0.10 audiotestsrc ! audioconvert ! autoaudiosink Setting pipeline to PAUSED ...

ERROR: Pipeline doesn't want to pause.

ERROR: from element /GstAlsaSink:autoaudiosink0-actual-sink-alsa: Could not ope.

Additional debug info: /home/user/vvdn_sdk/stct_iog1/source/yocto/build/tmp/work/cortexa9hf-vfp-neon-m:

Playback open error on device 'default': No such file or directory Setting pipeline to NULL ...

  • Check pipeline support enabled or disabled in kernel config. – Kanji Viroja Oct 25 '16 at 06:15
  • but how can i check whether pipeline support is enabled or not on imx6 board? if you have any idea then please let me know. – Amruta Oct 25 '16 at 06:37
  • use bitbake menuconfig command for that. – Kanji Viroja Oct 25 '16 at 07:23
  • Thnx @Kanji Viroja for your replay.... – Amruta Oct 25 '16 at 08:43
  • I don't have bitbake menuconfig option but i have other three options. 1)bitbake gnu-config 2)bitbake wmiconfig 3)bitbake fontconfig, so first i will try these option and after successful build , flash that image on board and then try to execute same command ... If have any problem then i'll let you know...thnx ones again. – Amruta Oct 25 '16 at 08:50
  • hello Kanji, I had try that solution but it's not working for me....after this try i got same error. If you have any other solution then please let me know. – Amruta Oct 27 '16 at 06:36
  • There should be a ".config" file in your kernel build directory, that is the kernel config, open that and check for CONFIG_SND_SOC* options. – Devarsh Thakkar Oct 27 '16 at 14:35
  • "Additional debug info: /home/user/vvdn_sdk/stct_iog1/source/yocto/build/tmp/work/cortexa9hf-vfp-neon-m:" Could you please post the output of this logs here ? Additionally for debugging runs as follows 1. export GST_DEBUG=5 2.gst-launch-0.10 audiotestsrc ! audioconvert ! autoaudiosink and check for error messages, you may also post it here so that anyone can see what the issue is – Devarsh Thakkar Oct 27 '16 at 14:36
  • Can you please share a log file? – Kanji Viroja Oct 28 '16 at 05:09
  • Hello Devarsh Thakkar, i tried that debugging and got same error. And also try to search for CONFIG_SND_SOC* in config file but i got these three PACKAGECONFIG_pn-qemu-native = "sdl" PACKAGECONFIG_pn-nativesdk-qemu = "sdl" PACKAGECONFIG_append_pn-gstreamer1.0-plugins-good = "vpx wavpack jack libv4l2" packages in local.conf file. I did not get any result related to CONFIG_SND_SOC*. – Amruta Nov 07 '16 at 04:54
  • /home/user/vvdn_sdk/stct_iog1/source/yocto/build/tmp/work/cortexa9hf-vfp-neon-mx6-poky-linux-gnueabi at this location I have several folders like cairo, gpu-viv-bin-mx6q, gst-plugins-base, libdrm, libfslcodec, libfslparser, libglu, libsdl, mesa, xserver-xorg and each folder contains it's own data...so which log file you want? – Amruta Nov 07 '16 at 05:32
