示例1: mixBuffer
size_t

{
std::lock_guard<std::recursive_mutex> lk(stateLock_);
const auto bindings = getReadBindings(call_id);

// No mixing
if (bindings->size() == 1)
return (*bindings->cbegin())->get(buffer, call_id);
buffer.reset();
buffer.setFormat(internalAudioFormat_);
size_t size = 0;
AudioBuffer mixBuffer(buffer);
for (const auto& rbuf : *bindings) {
// XXX: is it normal to only return the last positive size?
size = rbuf->get(mixBuffer, call_id);
if (size > 0)
buffer.mix(mixBuffer);
}
return size;
