## 为避免与3d数字人混淆，原项目metahuman-stream改名为livetalking，原有链接地址继续可用
## News
- 2024.12.8 完善多并发，显存不随并发数增加
## Features
1. 支持多种数字人模型: ernerf、musetalk、wav2lip
2. 支持声音克隆
3. 支持数字人说话被打断
4. 支持全身视频拼接
5. 支持rtmp和webrtc
6. 支持视频编排：不说话时播放自定义视频
7. 支持多并发
## 1. Installation
Tested on Ubuntu 20.04, Python3.10, Pytorch 1.12 and CUDA 11.3
### 1.1 Install dependency
```bash
conda create -n nerfstream python=3.10
conda activate nerfstream
conda install pytorch==1.12.1 torchvision==0.13.1 cudatoolkit=11.3 -c pytorch
pip install -r requirements.txt
#如果不训练ernerf模型，不需要安装下面的库
pip install "git+https://github.com/facebookresearch/pytorch3d.git"
pip install tensorflow-gpu==2.8.0
pip install --upgrade "protobuf<=3.20.1"
```
如果cuda为其他版本，上<https://pytorch.org/get-started/previous-versions/>安装相应版本的pytorch
安装常见问题[FAQ](https://livetalking-doc.readthedocs.io/en/latest/faq.html)
linux cuda环境搭建可以参考这篇文章 https://zhuanlan.zhihu.com/p/674972886
## 2. Quick Start
默认采用ernerf模型，webrtc推流到srs
### 2.1 运行srs
```bash
export CANDIDATE='<服务器外网ip>' #如果srs与浏览器访问在同一层级内网，不需要执行这步
docker run --rm --env CANDIDATE=$CANDIDATE \
-p 1935:1935 -p 8080:8080 -p 1985:1985 -p 8000:8000/udp \
registry.cn-hangzhou.aliyuncs.com/ossrs/srs:5 \
objs/srs -c conf/rtc.conf
```
### 2.2 启动数字人：
```python
python app.py
```
如果访问不了huggingface，在运行前
```
export HF_ENDPOINT=https://hf-mirror.com
```
用浏览器打开http://serverip:8010/rtcpushapi.html, 在文本框输入任意文字，提交。数字人播报该段文字
备注：服务端需要开放端口 tcp:8000,8010,1985; udp:8000
## 3. More Usage
使用说明: <https://livetalking-doc.readthedocs.io/>
## 4. Docker Run
不需要前面的安装，直接运行。
```
docker run --gpus all -it --network=host --rm registry.cn-beijing.aliyuncs.com/codewithgpu2/lipku-metahuman-stream:vjo1Y6NJ3N
```
代码在/root/metahuman-stream，先git pull拉一下最新代码，然后执行命令同第2、3步
提供如下镜像
- autodl镜像: <https://www.codewithgpu.com/i/lipku/metahuman-stream/base>
[autodl教程](autodl/README.md)
- ucloud镜像: <https://www.compshare.cn/images-detail?ImageID=compshareImage-14pa8x8ucwr9&ImageType=Community&ytag=cs_lipku_image>
可以开放任意端口，不需要单独运行srs服务.
## 5. 性能分析
1. 帧率
在Tesla T4显卡上测试整体fps为18左右，如果去掉音视频编码推流，帧率在20左右。用4090显卡可以达到40多帧/秒。
2. 延时
整体延时3s左右
（1）tts延时1.7s左右，目前用的edgetts，需要将每句话转完后一次性输入，可以优化tts改成流式输入
（2）wav2vec延时0.4s，需要缓存18帧音频做计算
（3）srs转发延时，设置srs服务器减少缓冲延时。具体配置可看 https://ossrs.net/lts/zh-cn/docs/v5/doc/low-latency
## 6. TODO
- [x] 添加chatgpt实现数字人对话
- [x] 声音克隆
- [x] 数字人静音时用一段视频代替
- [x] MuseTalk
- [x] Wav2Lip
- [ ] TalkingGaussian
