Play Raw OPUS.

[elshnkhll]

Thanks for GREAT work and countless hours invested into this unique project.

I am receiving raw OPUS packets (~120 byte) on a port of ESP32 every 20ms. Packets are not wrapped (no MP3 or OGG). First byte (TOC) is F4 = 11110100, meaning they are in CELT mode, stereo and 1 frame per packet, 48000 sample rate. Is it feasible to adapt your code to play this kind of stream?

Thanks in advance.
With wishes of success.

I don't know that exactly. Do you have an example of such a file?

It is not a file. I am getting UDP packets delivered to a port of ESP32. Similar to RTSP, but without any headers. Here is a payload example extracted from the event.data of a single event:

@elshnkhll did you figure this out?
