SpiceRecordChannel class handles an audio recording stream. The audio stream should start when “record-start” is emitted and should be stopped when “record-stop” is received.
The audio is sent to the guest by calling spice_record_send_data()
with the recorded PCM data.
Note: You may be interested to let the SpiceAudio class play and record audio channels for your application.
void spice_record_send_data (SpiceRecordChannel *channel,gpointer data,gsize bytes,guint32 time);
Send recorded PCM data to the guest.
struct SpiceRecordChannel;
The SpiceRecordChannel struct is opaque and should not be accessed directly.
struct SpiceRecordChannelClass {

void (*record_start)(SpiceRecordChannel *channel,
gint format, gint channels, gint freq);
void (*record_data)(SpiceRecordChannel *channel, gpointer *data, gint size);
