Detailed Description

Icecast/Shoutcast Audio Stream which splits the data into metadata and audio data. The Audio data is provided via the regular stream functions. The metadata is handled with the help of the MetaDataICY state machine and provided via a callback method.

This is basically just a URLStream with the metadata turned on.

◆ setPowerSave()

void setPowerSave ( bool  active)
inlinevirtual

if set to true, it activates the power save mode which comes at the cost of performance! - By default this is deactivated. ESP32 Only!

Implements AbstractURLStream.
