ffmpeg - playing, decoding, seeking, audio from command line -

-



there various way use audio, find several different audio players can following easily, command line:

  1. carry out standard audio function: play, pause, stop, seek(absolute), volume(absolute), mute.

  2. be able decode , raw data of audio input 1 can display waveform.

-- correct answers provide player, command line functions and/or how 1 can interact programmatically if necessary.

e.g.,

program: ffmpeg decode: pipe out using -i <filename> -f s16le -ac 1 - play: ffplay -nodisp send keys wmproc(keys don't work without window open , -nodisp closes window, wm keys) stop, pause, etc same. not have way absolutely seek or set volume.

other programs might vlc, etc.

the reason asking because provide several options program use user might have without having require shipping or downloading dlls(i.e., hard dependencies).

bonus points being able control pitch , speed.
