H.264 over RTP - Identify SPS and PPS Frames

為{幸葍}努か 提交于 2019-12-02 16:00:39
I have a raw H.264 Stream from an IP Camera packed in RTP frames. I want to get raw H.264 data into a file so I can convert it with ffmpeg . So when I want to write the data into my raw H.264 file I found out it has to look like this: 00 00 01 [SPS] 00 00 01 [PPS] 00 00 01 [NALByte] [PAYLOAD RTP Frame 1] // Payload always without the first 2 Bytes -> NAL [PAYLOAD RTP Frame 2] [... until PAYLOAD Frame with Mark Bit received] // From here its a new Video Frame 00 00 01 [NAL BYTE] [PAYLOAD RTP Frame 1] .... So I get the SPS and the PPS from the Session Description Protocol out of my preceding

IP地址是指互联网协议地址(英语:Internet Protocol Address,又译为网际协议地址),是IP Address的缩写。IP地址是IP协议提供的一种统一的地址格式,它为互联网上的每一个网络和每一台主机分配一个逻辑地址,以此来屏蔽物理地址的差异。 IP地址的长度为32位(共有2^32个IP地址),分为4段,每段8位,用十进制数字表示,每段数字范围为0~255,段与段之间用句点隔开。 IP地址格式: IP地址的长度为32位(共有2^32个IP地址),分为4段,每段8位 用十进制数字表示,每段数字范围为0~255,段与段之间用句点隔开。 // 0.0.0.0 ~ 255.255.255.255 根据规则:每段相同,范围都在 0 ~ 255 0~255 对应的正则表达式为 (2(5[0-5]|[0-4]\d))|[0-1]?\d{1,2} java: import java.util.regex.Matcher; import java.util.regex.Pattern; public class RegexMatches { public static void main(String args[]) { String str = ""; String pattern = "((2(5[0-5]|[0-4]\\d))|[0-1]?\\d{1,2})(\\.((2(5

使用Gstreamer处理RTSP视频流

Gstreamer组件 2.1 Element 2.2 Pad 2.3 Bin和Pipeline 3. gstreamer tools 3.1 gst-inspect-1.0 3.2 gst-launch-1.0 4. 参考链接 RTSP视频流处理方法 这里使用Gstreamer + OpenCV来处理RTSP视频流,因此对Gstreamer进行调查。 1. Gstreamer整体框架 Gstreamer是一个用于开发流式多媒体应用的开源框架,采用了基于插件(plugin)和管道(pipeline)的体系结构,框架中的所有的功能模块都被实现成可以插拔的组件(component), 并且能够很方便地安装到任意一个管道上。由于所有插件都通过管道机制进行统一的数据交换,因此很容易利用已有的各种插件“组装”出一个功能完善的多媒体应用程序。 Nvidia为Gstreamer开发了许多plugin,这些plugin能够利用Nvidia硬件进行加速。Nvidia的deepstream就是基于gstreamer开发的。 下图是对基于Gstreamer框架的应用的简单分层: 1.1 Media Applications

How to use gst-rtsp-server with own pipeline?

眉间皱痕 提交于 2019-12-02 05:45:16
I am writing gstreamer application and need to transfer output audio/video stream over rtsp. But in gst-rtsp-server examples I have founded factory creation only by gst-launch syntax: factory = gst_rtsp_media_factory_new (); gst_rtsp_media_factory_set_launch (factory, "( appsrc name=mysrc ! videoconvert ! x264enc ! rtph264pay name=pay0 pt=96 )"); Is it possible to connect gst-rtsp-server elements to my pipe? You have to subclass rtsp-media-factory and override default_create_element that will return your pipeline as GstElement 来源: https://stackoverflow.com/questions/22993373/how-to-use-gst

ffmpeg returns “method SETUP failed: 404 Not Found” [duplicate]

This question already has an answer here: Does FFMPEG support RTSP authentication? 7 answers We're using ffmpeg (build ffmpeg-20190628-098ab93-win32-static) to take a snapshot from camera RTSP streams on a Win 10 system. On some cameras, we're getting this error: [rtsp @ 06813ac0] method SETUP failed: 404 Not Found rtsp://username:password@example.com: Server returned 404 Not Found Here's an example command we use: ffmpeg -y -i rtsp://username:password@example.com -vframes 1 -pix_fmt yuvj420p -vf select='eq(pict_type\,I)' -q:v 1 _test.jpg However, VLC can load the same stream (we can't use VLC

Convert rtsp-stream into http stream

不羁岁月 提交于 2019-12-02 03:19:06
Often discussed but so far never working on windows with the current versions of vlc or ffmpeg. These are my stream's properties: How to do it with vlc or ffmpeg? I tried a lot. Way too much to list. I use this to convert a remote RTSP source to a local HLS streaming with ffmpeg and it works ok: ffmpeg -i "rtsp://yourRtspStreamSource" -hls_time 3 -hls_wrap 10 "yourOutputDir/streaming.m3u8" Also I use -t and -stimeout options to control the timeout of that proccess. More info about HLS ffmpeg in docs: https://ffmpeg.org/ffmpeg-formats.html#hls-1 来源: https://stackoverflow.com/questions/41836137

rtsp+rtmp多路流媒体播放

一、前言   之前博主有写过 一篇博文,讲的是使用videojs在谷歌浏览器网页上播放rtmp流媒体,具体可参考我之前的博客: https://www.cnblogs.com/FHC1994/p/9981440.html   最近又开始研究了一下网页播放流媒体,在这里我要主要补充一些播放rtmp、rtsp流媒体的其他方法 二、rtsp和rtmp流媒体 2.1 视频传输原理   从网络上接收视频时首先需要要解协议(RTSP/RTMP/HTTP),然后是解格式(MKV,RMVB),之后才是将视频(H264)和音频(AAC)格式数据分别解码为图像(RGB/YUV)和声音(PCM),再根据时间戳同步播放 2.2 RTSP和RTMP介绍      RTSP(Real Time Streaming Protocol),RFC2326,实时流传输协议,是TCP/IP协议体系中的一个应用层协议,由哥伦比亚大学、网景和RealNetworks公司提交的IETF RFC标准。该协议定义了一对多应用程序如何有效地通过IP网络传送多媒体数据。RTSP在体系结构上位于RTP和RTCP之上,它使用TCP或UDP完成数据传输。目前多数网络摄像机支持RTSP、ONVIF等通用的协议,而支持RTMP比较少   RTMP是Real Time Messaging Protocol(实时消息传输协议)的首字母缩写

EasyPlayer是一个RTSP专属的流媒体播放器,在GitHub上开源大部分源码其主要功能有播放、抓图、录制视频、实时静音/取消静音。 GDI和D3D两种视频渲染方式的区别 EasyPlayer-RTSP windows播放器支持D3D和GDI两种渲染方式。 D3D支持格式如下: DISPLAY_FORMAT_YV12 DISPLAY_FORMAT_YUY2 DISPLAY_FORMAT_UYVY DISPLAY_FORMAT_A8R8G8B8 DISPLAY_FORMAT_X8R8G8B8 DISPLAY_FORMAT_RGB565 DISPLAY_FORMAT_RGB555 GDI支持格式如下: DISPLAY_FORMAT_RGB24_GDI GDI渲染方式则是我们熟知的采用GDI进行图像绘制,其优势就是通用性强,只要是目前常用的windows操作系统基本上都支持;其劣势就是效率比较低下,也只支持RGB24一种色彩格式显示; D3D渲染方式则刚好相反,其优势就是效率比较高,支持多种色彩格式进行渲染;劣势就是通用性较差,windows系统必须要支持D3D才可以使用,需要一定的硬件支撑。 GDI渲染格式界面选择如下: D3D渲染格式界面选择如下: 从界面上可以看出GDI方式的OSD字幕叠加比D3D方式有明显的区别
