This is a small linux audio playback example using FFmpeg and alsa.

This project use cmake to compil, make sure you have FFmpeg/libav and libasound installed. Default c++ version is c++17 but I think th other version would work fine.

cmake .
make
build/decode_and_play {path_to_audio_file}

Decoder

• PcmReader: read pcm data from the file and pass data to player.
• FFmpegDecoder: decode audio file and output pcm data to player.

Player

• PcmDumper: Dump pcm data from the decoder to file.
• AlsaPlayer: Play pcm data using alsa interface.

• wav
• mp3
• m4a
• aiff
