Hi everyone,


I  am working on imx8Mm-evk, using sumo version of Freescale-BSP and trying to play a video VP9 file with Gstreamer.


When I play only the video with the below Gstreamer pipelines, video plays correctly:


gst-launch-1.0 -v filesrc location=vp9.webm ! matroskademux ! queue ! vpudec ! waylandsink async=false enable-last-sample=false qos=false sync=true


But when I want to play video with audio(below), then the screen gets black and the Gstreamer pipeline is not stopped.


gst-launch-1.0 -v filesrc location=vp9.webm ! matroskademux name=demux demux. ! queue ! vpudec ! waylandsink demux. ! queue max-size-buffers=0 max-size-time=0 ! beepdec ! alsasink


Could anyone help me and let me know what is the correct pipeline?
