Encode an interleaved floating-point PCM frame into a Dolby access unit.
- Parameters
-
| interleaved | Interleaved float PCM samples for one complete frame. |
| output | Destination buffer for the encoded access unit. |
- Returns
- Encoded access-unit size in bytes, or -1 if input validation or encoding fails.
◆ initialize()

std::int64_t | bit_rate, |
|
|
int | channels ) |
|
inline |
Initialize the selected FFmpeg encoder for stereo or 5.1 PCM.
- Parameters
-
| codec_id | FFmpeg codec identifier for AC-3 or E-AC-3. |
| bit_rate | Target encoded bitrate in bits per second. |
| channels | Number of channels; only 2 and 6 are supported. |
- Returns
- True if the encoder context and frame buffers initialize successfully.
