A streaming digital human based on the Ernerf model, realize audio video synchronous dialogue. It can basically achieve commercial effects.
基于ernerf模型的流式数字人,实现音视频同步对话。基本可以达到商用效果

Installation

Tested on Ubuntu 18.04, Pytorch 1.12 and CUDA 11.3.

Install dependency

pip install pytorch==1.12.1 torchvision==0.13.1 cudatoolkit=11.3 -c pytorch
pip install -r requirements.txt
pip install "git+https://github.com/facebookresearch/pytorch3d.git"
pip install tensorflow-gpu==2.8.0

linux cuda环境搭建可以参考这篇文章 https://zhuanlan.zhihu.com/p/674972886

安装rtmpstream库
参照 https://github.com/lipku/python_rtmpstream

Run

运行rtmpserver (srs)

docker run --rm -it -p 1935:1935 -p 1985:1985 -p 8080:8080 registry.cn-hangzhou.aliyuncs.com/ossrs/srs:5

启动:

python app.py

如果访问不了huggingface,在运行前

export HF_ENDPOINT=https://hf-mirror.com

运行成功后,用vlc访问rtmp://serverip/live/livestream

网页端数字人播报输入文字

安装并启动nginx

apt install nginx
nginx

修改echo.html中websocket和视频播放地址,将serverip替换成实际服务器ip
然后将echo.html和mpegts-1.7.3.min.js拷到/var/www/html下

启动数字人

python app.py

用浏览器打开http://serverip/echo.html,在文本框输入任意文字,提交。数字人播报该段文字

Data flow

数字人模型文件

可以替换成自己训练的模型(https://github.com/Fictionarry/ER-NeRF)

TODO

  • 添加chatgpt实现数字人对话
  • 声音克隆
  • 数字人静音时用一段视频代替
