A streaming library for esp32, esp32-wrover, esp32-s2 and esp32-s3 with a separate VS1053 codec chip.
This library plays mp3, ogg, aac, aac+ and flac files and streams and uses ESP_VS1053_Library to communicate with the decoder.
Supports http, https (insecure mode) and chunked audio streams.
Visit eStreamPlayer32_VS1053 for PIO to see a PlatformIO project using this library.
Install ESP_VS1053_Library and this library in your Arduino library folder.
Take care to install the master branch of the VS1053 library or at least a version from commit ba1803f or later because the getChipVersion() call that is needed is not included in the latest release.
See #23
Use the latest Arduino ESP32 core version.

...Early version of the esp32 have issues with the external psram cache, resulting in reboots.
Workarounds are possible depending on the hardware revision.
No workarounds are possible for this revision other than not using the psram.
On revision V1.0 psram can be used with the following build flags:
-D BOARD_HAS_PSRAM
-mfix-esp32-psram-cache-issue
-mfix-esp32-psram-cache-strategy=memwOn revision V3.0 psram can be used with the following build flag:
-D BOARD_HAS_PSRAMSource: esp-idf api guide on external ram.
In PIO you can find out what hardware revision you have by running esptool.py flash_id in a terminal.
In Arduino IDE go to File->Preferences and find the Show verbose output during option. Check the box marked upload.
You can now see the hardware revision when you upload a sketch.
bool startDecoder(CS, DCS, DREQ)bool isChipConnected()bool connecttohost(url)bool connecttohost(url, offset)bool connecttohost(url, user, pwd)bool connecttohost(url, user, pwd, offset)void stopSong()void loop()This function has to called every couple of ms to feed the decoder with data.
For bitrates up to 320kbps somewhere between 5-25 ms is about right.
bool isRunning()uint8_t getVolume()void setVolume(uint8_t volume)Value should be between 0-100.
uint8_t rtone[4] = {toneha, tonehf, tonela, tonelf};
void setTone(rtone)Values for rtone:
toneha = <0..15> // Setting treble gain (0 off, 1.5dB steps)
tonehf = <0..15> // Setting treble frequency lower limit x 1000 Hz
tonela = <0..15> // Setting bass gain (0 = off, 1dB steps)
tonelf = <0..15> // Setting bass frequency lower limit x 10 Hzconst char* currentCodec()Returns STOPPED if no stream is running.
const char* lastUrl()The current stream url might differ from the request url if the request url points to a playlist.
size_t size()Returns 0 if the stream is a radio stream.
size_t position()Returns 0 if the stream is a radio stream.
const char *bufferStatus()Returns 0/0 if there is no buffer.
Otherwise returns something like 4096/65536 which means 4kB waiting in a 64kB buffer.
void bufferStatus(size_t &used, size_t &capacity)There is also a version that takes two size_t variables by reference.
Works the same as the const char * version.
A buffer will only be allocated if there is enough free psram.
void audio_showstation(const char* info)void audio_showstreamtitle(const char* info)void audio_eof_stream(const char* info)Returns the eof url.
Also called if a stream times out/errors.
Handy function for coding a playlist.
You can use connecttohost() inside this function to start the next item.
