Codec\AudioCodec

A string-backed enum naming the audio encoder for MediaEncoder::addAudio(). The backing value is the FFmpeg encoder name (or "copy"), so the choice is an output decision that lives on the addAudio() call — not on the stream.

Cases

Case	Backing value	Notes
AAC	aac	FFmpeg’s native AAC encoder (always available).
MP3	libmp3lame	Requires FFmpeg built --enable-libmp3lame.
Opus	libopus	Requires --enable-libopus.
FLAC	flac	Lossless; native encoder.
Copy	copy	Stream-copy / remux — no re-encode.

If the chosen encoder isn’t built into the running FFmpeg, save() throws EncoderNotFoundException.

Example

use FFmpeg\Codec\AudioCodec;

AudioCodec::AAC->value;   // "aac"
$encoder->addAudio($stream, AudioCodec::Copy);   // remux, no re-encode
