Hi

I tried to combine both audio and video using a single gstreamer pipeline .But I am getting a warning as shown below
GST_ARGUS: PowerService: requested_clock_Hz=25804800
GST_ARGUS: Setup Complete, Starting captures for 0 seconds
GST_ARGUS: Starting repeat capture requests.
CONSUMER: Producer has connected; continuing.
WARNING: from element /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0: Can’t record audio fast enough
Additional debug info:
gstaudiobasesrc.c(849): gst_audio_base_src_create (): /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0:
Dropped 1210 samples. This is most likely because downstream can’t keep up and is consuming samples too slowly.

The pipeline used is
gst-launch-1.0 -e nvarguscamerasrc ! ‘video/x-raw(memory:NVMM), width=(int)3840, height=(int)1920, format=(string)NV12,framerate=(fraction)16/1’ ! queue ! omxh264enc profile=8 bitrate=10000000 ! mux. alsasrc ! audio/x-raw,width=16,depth=16,rate=44100,channel=1 ! queue ! audioconvert ! audioresample ! voaacenc ! aacparse ! flvmux name=mux ! filesink location=test.mp4 sync=false

please help…
thanks in advance…

Hi,
Audio encoding is on CPU and please execute sudo jetson_clocks to run at max clocks. And you may use nvv4l2h264enc and enable

  maxperf-enable      : Enable or Disable Max Performance mode
                        flags: readable, writable, changeable only in NULL or READY state
                        Boolean. Default: false
