• - major change, use lwip netconn instead of socket API to reduce RAM footprint

  o flac works, opus and pcm are untested and not working
  - improve on resyncing issues
  - add wifi logger component submodule
  - optimize stack sizes

• setting client latency from Android app works now, reduce latency buffer size, only start flac decoder if necessary

• - completely drop ADF but copy necessary parts

  o copy component audio_board from ADF and create custom component from it
    o copy component audio_hal from ADF and create custom component from it
    o copy component audio_sal from ADF and create custom component from it
    o copy component esp_peripherals from ADF and create custom component from it
  - add fLaC support through xiph's original repository as a git module

• - rename a view things

  - run player_task on core 1 with max priority
  - create/destroy chunk queue as required automatically
  - use mutex to access snapcast config and communicate this change by queue with size 1
  - increase buffers for WIFI and LWIP in sdkconfig for NO_SPIRAM config
  - add some more debug output

• - clean up code

  - add pre commit using GNU style
  - remove some minor issues regarding the use of global variables and such

• - add sdkconfig for NO_SPIRAM and SPIRAM situation

  - detect snapcast configuration and init everything accordingly, e.g sample rate, chunk duration, ...
    o calculate apll predefines in dependence of sample rate
    o communicate these settings to interested parties
  - remove typos

• - merge with original master from jorgen

  - minimize RAM usage of all components
  - use both IRAM and DRAM in player component so we can buffer up to 1s on modules without SPI RAM
  - support fragemented pcm chunks so we can use all available RAM if there isn't a big enough block available but still enough HEAP
  - reinclude all components from jorgen's master branch
  - add custom i2s driver to get a precise timing of initial sync
  - change wrong usage of esp_timer for latency measurement of snapcast protocol
  - add player component

• - change buffer sizes of medians

  - change syncing to be more predictable using I2S_EVENT_TX_DONE
    o also increase DMA length so i2s won't eat up so much processing time
    o ensure at least one chunk is in DMA buffer

• - prefer SPIRAM for LWIP

  - try to improve synced playback using APLL adjustments
  - reduce diffBuf size to 1, bigger values seem to be problematic if packet loss is happening, maybe we need to detect this and clear diffBuf
  - do early time syncs on boot to fill diffBuf
  - playing with pipline ringbuf sizes and I2S DMA buffer sizes

• - add eclipse project configuration

  - use espressif ADF, remove external opus rep
    o uses audio pipelines now
  - change code to use flac decoder
  - remove mersus code
  - add first try of audio synchronization
    o needed to sync timeofday to server on reception of server settings to avoid overflows in timeval calculations (int32_t on esp32 SDK)
    o still a lot of TODO's in the code, but it's almost in sync, although there is quite some chunk skipping which I am currently working on
