- *
- * This avdevice encoder allows to play audio to an ALSA (Advanced Linux
- * Sound Architecture) device.
- *
- * The filename parameter is the name of an ALSA PCM device capable of
- * capture, for example "default" or "plughw:1"; see the ALSA documentation
- * for naming conventions. The empty string is equivalent to "default".
- *
- * The playback period is set to the lower value available for the device,
- * which gives a low latency suitable for real-time playback.
