python_rtmpstream_4">一、关于 python_rtmpstream

python_rtmpstream 基于ffmpeg api函数实现推送rtmp流，实现了音视频同步。

• github ： https://github.com/lipku/python_rtmpstream

---

二、安装

1、下载代码

git clone https://github.com/lipku/python_rtmpstream.git
cd python_rtmpstream
git submodule update --init

---

2、安装依赖库

pip install wheel
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge
conda install ffmpeg 
或者 apt install libavcodec-dev libavformat-dev libswscale-dev

---

3、修改 python/CMakeLists.txt 文件, 根据python和ffmpeg安装路径修改如下部分(这一步一定要做，很多错误都是这里没改引起的)

set(PYTHON_EXECUTABLE /opt/anaconda3/envs/python37/bin/python)  #python bin dirinclude_directories("/opt/anaconda3/envs/python37/include") #ffmpeg include dir
find_library(AVCODEC_LIBRARY avcodec /opt/anaconda3/envs/python37/lib) #ffmpeg lib dir
find_library(AVFORMAT_LIBRARY avformat /opt/anaconda3/envs/python37/lib)
find_library(AVUTIL_LIBRARY avutil /opt/anaconda3/envs/python37/lib)
find_library(SWSCALE_LIBRARY swscale /opt/anaconda3/envs/python37/lib)

---

如果是 python3.10 以下，不能用相对路径，需要将如下部分改成绝对路径

include_directories("../streamer")pybind11_add_module( ../streamer/streamer.cpp) 

---

4、安装python库

cd python
pip install .

---

三、运行测试程序

python test_stream.py
