问题 I have a question about the RTSP Stream. How can I display a RTSP Stream from a netwok camera in qml? the settings: Qt5.10 Camera: LunaIP L-DA-5203-V2 OS: Windows 7 Things I have tested: QML: Camera, MediaPlayer, VideoOutput Until now I didn't found any things how I can solve it in QML? 回答1: There are 2 ways, which worked for me: 1.) In my form.ui.qml I'm using the MediaPlayer and the VideoOutput components MediaPlayer { id: videoPlayer source: "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k

libEasyPlayer RTSP windows播放器SDK API接口设计说明

帅比萌擦擦* 提交于 2020-02-14 03:45:15
概述 libEasyPlayer实现对RTSP直播流进行实时采集和解码显示,稳定,高效,低延时;解码可采用intel硬件解码和软件解码两种方式,能实时进行录像和快照抓图,OSD叠加等功能。 API接口函数定义  int EasyPlayer_Init(); 函数说明: 播放器初始化,播放器使用之前调用; 参数说明:  void EasyPlayer_Release(); 函数说明: 播放器资源释放,播放器不再使用以后调用; 参数说明: int EasyPlayer_OpenStream(const char *url, HWND hWnd, RENDER_FORMAT renderFormat, int rtpovertcp, const char *username, const char *password, MediaSourceCallBack callback, void *userPtr, bool bHardDecode); 函数说明: 播放器开始进行流播放;返回值为当前播放的通道ID,该ID在停止推流时需要用到; 参数说明: Url:[IN] 字符串类型,表示当前要播放的流地址,Eg: rtsp://127.0.0.1:554/stream.sdp HWnd: [IN] 窗口句柄类型,表示为当前播放器将显示的窗口的句柄; renderFormat:[IN]

如何设计一款跨平台低延迟的RTMP/RTSP直播播放器

流过昼夜 提交于 2020-02-08 12:54:13
开发背景 2015年,当我们试图在市面上找一款专供直播播放使用的低延迟播放器,来配合测试我们的RTMP推送模块使用时,居然发现没有一款好用的,市面上的,如VLC或Vitamio,说白了都是基于FFMPEG,在点播这块支持格式很多,也非常优异,但是直播这块,特别是RTMP,延迟要几秒钟,对如纯音频、纯视频播放,快速启播、网络异常状态处理、集成复杂度等各方面,支持非常差,而且因为功能强大,bug很多,除了行业内资深的开发者能驾驭,好多开发者甚至连编译整体环境,都要耗费很大的精力。 我们的直播播放器,始于Windows平台,Android和iOS同步开发,基于上述开源播放器的各种缺点,我们考虑全自研框架,确保整体设计跨平台,再保障播放流程度的前提下,尽可能的做到毫秒级延迟,接口设计三个平台统一化,确保多平台集成复杂度降到最低。 整体方案架构 RTMP或RTSP直播播放器,目标很明确,从RTMP服务器(自建服务器或CDN)或RTSP服务器(或NVR/IPC/编码器等)拉取流数据,完成数据解析、解码、音视频数据同步、绘制。 具体对应下图 “接收端” 部分: ​ 初期模块设计目标 自有框架,易于扩展,自适应算法让延迟更低、解码绘制效率更高; 支持各种异常网络状态处理,如断网重连、网络抖动等控制; 有Event状态回调,确保开发者可以了解到播放端整体的状态,从纯黑盒不可控

摄像头RTSP流硬解码

1. 问题分析 项目中,之前用的是OpenCV对摄像头的RTSP流进行解码。随着时间的推移以及业务摄像头的增加,发现十路流CPU就已经100%啦,很明显解码所占CPU资源较多,导致整个系统处理效率不高,解码成为系统的瓶颈,需要赶紧马上上硬解码才行。 查找资料并验证发现:OpenCV中VideoReader_GPU可以方便地利用GPU读取视频文件加速解码过程,但OpenCV中VideoReader_GPU无法读取rtsp视频流数据。 CUVID中CuvideoSource不支持rtsp视频流数据,不能由rtsp地址创建 VideoSource 。 硬解码跟计算机显卡有关,赶紧安装cuda_9.0.176_win10 .exe,然后找相关GUP加速相关厂商提供的加速解决方案Demo( C:\ProgramData\NVIDIA Corporation\CUDA Samples\v9.0\3_Imaging\cudaDecodeD3D9 ) cudaDecodeD3D9 Demo CUVID中CuvideoSource不支持rtsp视频流数据,不能由rtsp地址创建VideoSource , 利用其他方式解析RTSP流 硬解码基本架构流程 2.硬解码rtsp视频流 基本思路:跳过VideoSource模块,利用其他方式(FFmpeg)解析,我结合。 基本步骤: 1.

Displaying RTSP on website

问题 I have a RTSP link to a camera which I want to display on a web page. Since the video tag does not support RTSP, and google chrome does not support VLC and QuickTime plugins anymore, what is currently the best way to display this camera using the RTSP link? 回答1: If latency is not a great consideration you can use ffmpeg to generate a HLS playlist and serve it to clients via an HTTP server - see this. Otherwise you would need solution that would output a live fragmented MP4 stream. 回答2: You

How to directly use Twilio TURN server for Android (Server, Client)

馋奶兔 提交于 2020-01-24 21:31:05
问题 I have libstreaming RTSP server on Android device (open some port and wait for client p2p connection). I'm able to connect to the server via local network. For outside p2p connection I have to use STUN / TURN. I read a lot about Twilio. They wrote about TURN server: NETWORK TRAVERSAL, but didn't actually provide clear example of how to use it. They have some ready solutions I don't need. Is it possible to use Twilio directly as TURN server for video streaming, without any additional

问题 Does anyone have any code or can point me in the right direction for integrating live555 into an iPhone app. I know that you can build the live555 C++ library for iOS but am not sure about the actual integration of this at a code level. A link to a tutorial or some code would be wonderful :) Thanks. 回答1: Download live555 here Unpack it somevhere (in my case /Volumes/OSX/live) find config.iphoneos an open it using text editor change LINK_OPTS to LINK_OPTS = -L. -arch armv7 --sysroot=$(SDK) -L$
