在第一节我们可以看到,payload指针在数据传递过程中需要频繁的移动,这个过程是由函数pbuf_header();实现的。 AI检测代码解析 //header_size_increment>0,payload前移,数据传递下层 //header_size_increment<0,payload后移,数据传递上层 pbuf_header(struct pbuf *p, s16_t header_size_increment) { return pbuf_h...
case PBUF_IP:/* add room for IP layer header *//* 如果为ip层申请pbuf,那么有效数据的偏移位置为PBUF_ip_HLEN + PBUF_LINK_HLEN */offset= PBUF_LINK_HLEN + PBUF_IP_HLEN; case PBUF_LINK:/* add room for link layer header *//* 如果是链路层申请pbuf内存,那么有效数据的偏移位置为PBUF_LINK_...

Once modified the pbuf_header function in order to avoid the unlucky sequence of instruction that "fake" the cache controller (just add a dummy read operation before the return statement) we never got the error anymore. Translate 0 Kudos Copy link Reply Altera_Forum Honored Contributor II ...
packet.m_headerType = RTMP_PACKET_SIZE_LARGE;: 设置数据包头类型为大包。 packet.m_packetType = RTMP_PACKET_TYPE_CHUNK_SIZE;: 设置数据包类型为块大小设置。 packet.m_nTimeStamp = 0;: 时间戳设置为0。 packet.m_nInfoField2 = 0;: 通常用来指定接收方的信息字段,这里设为0。
