tinycap 用法 与tinycap封装成类实现

在Linux 下 开发经常用到tinycap 抓取I2S数据

tinycap 抓取命令如下

-D 表示声卡

-d 表示通道一般为0

-c 表示数据通道

-r表示采样频率 -b 表示采用bit

tinycap /sdcard/test.pcm -D 1 -d 0 -c 8 -r 32000 -b 16 -n 10

tinycap 源码位于RKAndroid12/external/tinyalsa

查看tinyalsa/pcm_hw.c 发现它是使用了ALSA API实现，如果图个简单可以用那个去做写个简洁点的demo网上例子很多
