Parser variables corresponding to one alsa device.
ALSA separates audio capture and audio playback into two different devices that have to be opened separately. This class encapsulates the parser variables that pertain to one such direction.
| alsa_dev_par_parser_t::alsa_dev_par_parser_t | ( | snd_pcm_stream_t | stream_dir | ) |
Constructor inserts the parser variables into this sub-parser.
| stream_dir | capture or playback |
| MHAParser::string_t alsa_dev_par_parser_t::device |
Name of the device in the alsa world, like "hw:0.0", "default", etc.
| MHAParser::int_t alsa_dev_par_parser_t::nperiods |
Number of buffers of fragsize to hold in the alsa buffer.
Usually 2, the minimum possible.
| snd_pcm_stream_t alsa_dev_par_parser_t::stream_dir |
Remember the direction (capture/playback) of this device.
