Pipeline syntax error | unable to find the root cause

[Rohan0993]

Hi all,
I am unable to make this pipeline work.

*gst-launch-1.0 filesrc=/path/to/fle/Tornado.wav ! wavparse !
autoaudioconvert ! audio/x-raw,channels=1,depth=16,width=16,rate=44100 !
rtpL16pay ! udpsink host=xxx.xxx.xxx.xxx port=yyyy*

I am trying to take a wave file from a local location and throw it on the ip
xxx.xxx.xxx.xxx (my system ip) and port yyyy.

I am getting syntax erroras:

*WARNING: erroneous pipeline: syntax error*

I have checked with *gst-inspect-1.0 *for *filesrc, wavparse,
autoaudioconvert, and udpsink. *All are installed (apparently).

What might have gone wrong? any suggestion on how to go ahead?

Add a decoder element after wavparse.

This should be: filesrc location=/path/to/fle/Tornado.wav

Use audioconvert instead. Maybe also add an audioresample if needed (in
front of the audioconvert, not after it, because you may need to work
in non-native endianness because of the payloader).

> audio/x-raw,channels=1,depth=16,width=16,rate=44100 !

depth and width are expressed in the "format" now, so replace
depth=16,width=16 with something like format=S16BE or S16LE (rtpL16pay
needs big-endian, so use BE here, or just don't specify the format at
all, it will figure it out automatically).

Cheers
