8-channel raw audio file playback

[Weipeng He]

Hi all,

I am trying to play an 8-channel raw audio file with gst-launch.
However, with the following commands, I didn't make it work:

  gst-launch-1.0 filesrc location=file !
audio/x-raw,format=S16BE,rate=8000,channels=8 ! audioconvert ! autoaudiosink

OR (play the first channel)

  gst-launch-1.0 filesrc location=file !
audio/x-raw,format=S16BE,rate=8000,channels=8 ! deinterleave name=d
d.src_0 ! queue ! audioconvert ! autoaudiosink

The error message is:

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc0: Internal
data flow error.
Additional debug info:
gstbasesrc.c(2948): gst_base_src_loop ():
/GstPipeline:pipeline0/GstFileSrc:filesrc0:
streaming task paused, reason not-negotiated (-4)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...

It seems that it works totally fine with one or two channels. But with
more than two channels the error will occur. Is it because I didn't set
the channel positions? How can I set them?

I appreciate your help.

Best,
Weipeng

Use audioparse to properly frame and align your stream.
