Hi,
I have been using rtpdump
with an AES67 compatible Dante device:
https://www.aelius.com/njh/posts/0002
The error Line {RIFF???WAVEfmt }
indicates that you are trying to send a WAV file. The rtpsend
command uses its own special text based file format - as output by rtpdump -F ascii
. And rtpplay
uses the rtpdump -F dump
file format. The dump file formats contain timing and RTP packet information, not just the raw audio samples / payload.
Unfortunately the official rtptools website is offline at the moment (see #135) but there is a copy of the page documenting the file format here:
http://www.cs.cmu.edu/~./libra-demo/rtptools-1.17/rtptools.html
You would need some kind of tool to convert the WAV file into RTP packets before it could be sent by rtpplay / rtpsend.
Maybe your Omnia One will be more tolerant than my Dante device, but I suspect that you may run into trouble with getting the AES67 device to accept RTP packets generated by rtpplay
because of clocking problems. You will have to make sure that your system clock is synced to the Omnia's clock (using PTPv2) and that the RTP media clock matches.
I really wish there was more Open Source tooling available for AES67. I keep meaning to spend some time on it... what is you end-goal?
