分享关于海康摄像头rtsp视频流传输的问题
手里有一个海康摄像头产生的rtsp视频流，如果想在ubuntu下通过FFmpeg程序让该视频流进行传输，并且能在远程ip上能实时播放，是什么个流程？大神们指点下迷津

终于找到设置tcp的方式了。
FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(rtspPath);
grabber.setOption("rtsp_transport", "tcp");
grabber.start();leeking888 2017-08-23

我使用javacv的FFmpegFrameGrabber获取海康的rtsp实时流也是有这个问题，不知道有没有人如何设置FFmpegFrameGrabber的为tcp的协议。我感觉会不会是grab()处理的太慢，后面的流太大了无法处理导致把前面的数据覆盖而造成的呢？
以下是错误的代码：

我现在有时也会出现这个问题，也没有完全解决 不过你尝试着把buffer调调整大一些试试，我之前动过FileMaxSize这里出现 你的情况，不过当我调整到100后 解码出现的频率低了很多

楼主，你好，我现在把ffmpeg移植到arm板子上，也出现了解码264文件出错，请教你是怎么解决的？
我看了你和那位大佬的交流信息，发现关于那个好像是加上TCP获取就可以了，但是我用TCP获取之后还是会出现解码错误，另外录制下来的视频明显缺帧

谢谢大哥的一路支持 今天晚上19.22分 总算把视频流在vlc上面播放出来了 我觉得在格式注意的前提下和电脑也有关系，换了三台电脑 在最后一台上实现了 ，真心谢谢

你上面的http://localhost:9999/teststat.html少了2个斜杠，我上传的conf里没有添加teststatus的，你需要的话在末尾加上<Stream teststat.html>
Format status
</Stream>
ffserver conf的格式一定要写对，否则可能会出现莫名其妙的问题。ffserver安装很简单，你下个源码包，解压后先进到解压目录,先./configure, 然后make就好了.或则你直接用我编译好的http://download.csdn.net/detail/qprevf/9694322

大哥 谢了这么耐心的教导
这个配置文件 我原封不动的写了 但是问题依旧vlc一打开就停了，
（1）关于这个ffsever.conf配置文件的放置和书写有什么讲究么？
（2）我尝试着 在
ffserver -f /etc/ffserver.confhttp:localhost:9999/teststat.htmlqprevf 2016-11-25

你的ffserver,conf就用我给你的，不要改。看你上面log是ffserver挂掉了。我这边用虚拟机测了下，没问题呀

环境是这样的 我是台式机，在win10下安装了VMware虚拟机 虚拟机里面安装了ubuntu14.04
台式机通过无线网卡链接到小米路由器
海康威视摄像头通过网线链接在路由器上
理论上 台式机和摄像头在同一局域网下
通过 win10 下的vlc 和虚拟机下的vlc均可以在输入视频流的时候查看到摄像头的视频流

这是你的ffmpeg没法连上摄像头， 能告知你的网络环境吗？你的Ubuntu是在虚拟机的环境下，然后摄像头跟电脑在一个局域网？

谢谢您的耐心，昨天回复您时候，马虎打错了vlc的输入，
按照您的方法再修改了下，不知道是不是打开的方式不对，提示的错误还在，特把操作过程贴出来，还请帮我看下指出其中的不当之处
