About VLC
默认 CD 格式： 44.1 kHz 2ch 16bit
UDP数据包 1400 X 3 + 456 实际载荷 1388 X3 + 444 = 4608 Bytes
4608 / 2 /2 = 1152 采样点
VLC 设置 –mtu 156 每包载荷 144 Byte， 1152 采样点 产生 4608 Byte 数据， 产生 32 包数据。
载荷 144 Bytes → 156 Bytes RTP Package → 164 Byts UDP → 184 bytes IP pkg → 198 Byte MAC pgkg 效率 72%
帧间隔 = 1152 / 44100 / 32 = 8.1632e-4 即 0.816 ms
