5.2 Seek过程：需要关闭socket重新建立连接。
1. 发送GET请求，需要包含Range域信息，如Range: bytes=(int64_t)pos \，表示数据从pos开始。 2. 得到响应信息并解析
http_seek( stream_t *stream, off_t pos ) { HTTP_header_t *http_hdr = NULL; int fd; if( stream==NULL ) return 0; if( stream->fd>0 ) closesocket(stream->fd); // need to reconnect to seek in http-stream fd = http_send_request( stream->streaming_ctrl->url, pos ); if( fd<0 ) return 0; http_hdr = http_read_response( fd ); if( http_hdr==NULL ) return 0; if( mp_msg_test(MSGT_NETWORK,MSGL_V) ) http_debug_hdr( http_hdr ); switch( http_hdr->status_code ) { case 200: case 206: // OK mp_msg(MSGT_NETWORK,MSGL_V,\[%s]\\n\http_get_field(http_hdr, \ mp_msg(MSGT_NETWORK,MSGL_V,\[%s]\\n\http_get_field(http_hdr, \ if( http_hdr->body_size>0 ) { if( streaming_bufferize( stream->streaming_ctrl, http_hdr->body, http_hdr->body_size )<0 ) { http_free( http_hdr ); return -1; } } break;
default: mp_msg(MSGT_NETWORK,MSGL_ERR,MSGTR_MPDEMUX_NW_ErrServerReturned, http_hdr->status_code, http_hdr->reason_phrase ); closesocket( fd ); fd = -1; } stream->fd = fd; if( http_hdr ) { http_free( http_hdr ); stream->streaming_ctrl->data = NULL; } stream->pos=pos; return 1; }
HTTP seek交互过程： C ? S GET请求 GET
