snd_pcm_hw_params( ) 从设备配置空间选择一个配置,让函数 snd_pcm_prepare() 准备好 PCM 设备,以便写入 PCM 数据。snd_pcm_writei() 用来把交错的音频数据写入到音频设备。 初始化 PCM 设备的例程如下: 初始化 PCM 设备的例程 /* open a PCM device */ intopen_device(structmad_headerconst*header) {...
printf("Write error: %s\n", snd_strerror(err)); return-1; } } 这里用到了http://www.alsa-project.org/关于 ALSA 文档中的例子函数xrun_recovery( )。详细例子请参见http://www.alsa-project.org/alsa-doc/alsa-lib/_2test_2pcm_8c-example.html。使用此函数的目的是避免出现由于网络原因,声卡不...
