/GstPipeline:pipeline0/GstAlsaSrc:alsasrc0: Dropped 1760 samples. This is most likely downstream can't keep up and is consuming samples too slowly.

Hi All,

I am trying to receive audio using udpsrc from remote android phone.

My receiving end is raspberry pi board. And my command is as below:

"

gst-launch-1.0 -v --gst-debug-level=4 udpsrc port=5003 ! audio/x-raw,
layout=interleaved, rate=8000, format=S16LE, channels=2, endianness=4321,
width=16, depth=16, signed=true ! audioconvert ! autoaudiosink

"

I am facing issue sometimes - error line is:
"WARNING: from element /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0: Can't record audio fast enough Additional debug info: gstaudiobasesrc.c(863): gst_audio_base_src_create (): /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0: Dropped 1760 samples. This is most likely  downstream can't keep up and is consuming samples too slowly"

Q 1. How to avoid this error.?
 I tried using sync=false parameter But this creates delay and samples get misses.

Please help me out...?

Q.2  I am running the command in debugging  --gst-debug-level=4.  But it takes 7 seconds to start pipeline. How to reduce this time..?

Thanks,

Shrikant

Hi,

You are showing us the receiver pipeline, but the error you mention is
on the sender pipeline, or at least some other pipeline with alsasrc in
it.

Write it into a file with GST_DEBUG_FILE=/home/rpi/dbg.log  or

  gst-launch-1.0 ... 2>dbg.log

But the raspberry pi is not a beefy machine, so once you enable too
much debug logging it will be very slow. Better only enable logging for
specific debug categories to cut down on the volume.

Cheers
