1、为wireshark软件添加工具
将改脚本放到安装路径下
脚本内容
-- Dump RTP h.264 payload to raw h.264 file (*.264)
-- According to RFC3984 to dissector H264 payload of RTP to NALU, and write it
-- to from<sourceIp_sourcePort>to<dstIp_dstPort>.264 file. By now, we support single NALU,
-- STAP-A and FU-A format RTP payload for H.264.
-- You can access this feature by menu "Tools->Export H264 to file [HQX's plugins]"
-- Author: Huang Qiangxiong (qiangxiong.huang@gmail.com)
-- change log:
-- 2012-03-13
-- Just can play
-- 2012-04-28
-- Add local to local function, and add [local bit = require("bit")] to prevent
-- bit recleared in previous file.
-- 2013-07-11
-- Add sort RTP and drop uncompleted frame option.
-- 2013-07-19
-- Do nothing when tap is triggered other than button event.
-- Add check for first or last packs lost of one frame.
-- 2014-10-23
-- Fixed bug about print a frame.nalu_type error.
-- 2014-11-07
-- Add support for Lua 5.2(>1.10.1) and 5.1(<=1.10.1).
-- Change range:string() to range:raw().
-- Change h264_f.value to h264_f.range:bytes() because of wireshark lua bug.
-- 2015-06-03
-- Fixed bug that if ipv6 address is using the file will not generated.(we replace ':' to '.')

end找到安装路径下的这个文件，添加上
2、通过wireshark打开你要处理的包文件，过滤h264相关的包
3、使用该工具，会在对应的下载目录中，生成.264文件
4.该文件可以通过工具，播放视频
5，抓包文件有多个视频段，可以通过过滤条件分隔数据包，再分离视频
过滤时间写法
frame.time >= "May 27, 2019 15:23:57.0" && frame.time < "May 27, 2019 15:23:58.0"
通过文件->导出特定分组，将这段时间的包，导成一个独立的数据包，在进行分析
在网上找到了另一个脚本，功能类似，使用方法相同
