OpenAL如何播放单个buffer

[ibingow]

找到的所有例子都是播放一个文件，弄队列啊循环啊什么的。其实我的要求很简单，就是是把一帧的音频解出来后丢给al，al直接去放那个数据就行。应该怎么操作？感觉很少几行代码就行
还有，openal播放一个buffer时会不会阻塞住线程？

while(1) { alGetSourcei(s_Wavfile.source, AL_BUFFERS_PROCESSED, &s_Wavfile.val);//val值为排队的buffer个数 if(s_Wavfile.val > 0) break; j++; } while(s_Wavfile.val--) { alSourceUnqueueBuffers(s_Wavfile.source, 1, &s_Wavfile.buffer); alBufferData(s_Wavfile.buffer, s_Wavfile.format, out, frame_shift * 2 * 2, s_Wavfile.frequency); alSourceQueueBuffers(s_Wavfile.source, 1, &s_Wavfile.buffer); } alGetSourcei(s_Wavfile.source, AL_SOURCE_STATE, &s_Wavfile.val); if(s_Wavfile.val != AL_PLAYING) { Write_Log(LOG_TYPE_ERROR, "state not playing...\n"); alSourcePlay(s_Wavfile.source); } out是你的一帧数据流
