Yes I was wrong.
Opus needs a bigger buffer than mp3, increasing the size fixed it.
It works, sound is perfect from a https too.
Only remain a problem: after 10 seconds of playing, op_read_float() does not
give output.
I must study deep
Hello Lars.
Many thanks to spent your time for us.
But after lot of test and re-test, my conclusion is:
op_open_memory() is buggy.
It looses the pointer assigned to the input-buffer of bytes.
And when using op_read() it points to nil in place of buffer-in.
Voila.
(But maybe I m wrong...).

@ Lars:
The library used for op_memory_open and op_seek is libopusfile.so:
https://github.com/xiph/opusfile
Translation into fpc-Pascal of the header:
https://github.com/fredvs/uos/blob/master/src/uos_opusfile.pas
And Opusfile.so depends on libopus.so :

Nice tip !

This does not work:

PipeBufferSize, err);

Huh, IMO, the translation is ok.

Hello Fred,
I didn't understand the software structure / problem behind the C->
