Android平台GB28181设备接入端PTZ对接详解

PTZCmd实现背景上一篇blog“Android平台GB28181设备接入模块之球机/云台控制探究”谈到，Android平台做国标GB28181设备接入端的时候，PTZ控制要不要处理？如果处理，难度大不大？首先说要不要处理：如果只是做执法记录仪相关，Android终端作为数据采集模块，...

Android平台GB28181接入端如何对接UVC摄像头？

我们在对接Android平台GB28181接入的时候，有公司提出这样的需求，除了采集执法记录仪摄像头自带的数据外，还想通过执法记录仪采集外接UVC摄像头。实际上，这块对我们来说有点炒冷饭了，不算新的诉求。大牛直播SDK在2016年对接RTMP推送的时候，就有提供过YUV数据接口，供外部比如UVC C...

如何实现Android平台GB28181设备对接Camera2数据

技术背景在写如何实现Android平台GB28181设备对接Camera2数据说明之前，我在前两年的blog就有针对camera2的RTMP直播推送模块做过技术分享：在Google 推出Android 5.0的时候, Android Camera API 版本升级到了API2(android.har...

Android平台GB28181设备接入端对接编码前后音视频源类型浅析

前言今天主要对Android平台GB28181设备接入模块支持的接入数据类型，做个简单的汇总：编码前数据（目前支持的有YV12/NV21/NV12/I420/RGB24/RGBA32/RGB565等数据类型），其中，Android平台前后摄像头数据，或者屏幕数据，或者Unity拿到的数...

Android平台RTMP推送模块如何对接NV21、YV12、RGB、YUV等编码前数据

前言我们在对接Android平台摄像头或者屏幕采集、编码打包推送场景的时候，随着采集设备的不同，出来的数据也是多样化的，比如NV21、YV12、RGB、YUV等，更有图像数据甚至是翻转或者倒置的，如果上层处理，效率低下，本篇文章主要介绍下常用的编码前数据接口。相关资料或版本测试，也可联...

Android平台RTMP推送端实现外部数据对接推送和录像

背景好多开发者在做Android平台RTMP推送对接的同时，除了编码前的数据外，还有些外部编码数据推送诉求，他们希望外部的编码音视频数据不止可以实现RTMP推送，还可以同时在推送端实时录制下来，本文以我们（官方）Android平台RTMP直播推送模块为例，介绍下外部数据对接流程和数据录...

Android对接实现内网无纸化会议|智慧教室|实时同屏功能

背景本文主要讲的是基于Android平台实现RTMP的技术方案设计，基础架构图如下：组网注意事项1. 组网：无线组网，需要好的AP模块才能撑得住大的并发流量，推送端到AP，最好是有线网链接；2. 服务器部署：SRS或NGINX，服务器可以和Windows平台的教师机部署在...

Android平台Camera2数据如何对接RTMP推流到服务器

1. Camera2架构在Google 推出Android 5.0的时候, Android Camera API 版本升级到了API2(android.hardware.camera2), 之前使用的API1(android.hardware.camera)就被标为 Deprecated 了。Cam...
