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
