本项目实现了一个python库,基于ffmpeg api函数实现推送rtmp流,实现了音视频同步。
下载代码
$ git clone https://github.com/lipku/python_rtmpstream.git
$ cd python_rtmpstream
$ git submodule update --init
安装依赖库
$ pip install wheel
$ conda install ffmpeg
或者 apt install libavcodec-dev libavformat-dev libswscale-dev
修改python/CMakeLists.txt文件,根据python和ffmpeg安装路径修改如下部分
set(PYTHON_EXECUTABLE /opt/anaconda3/envs/python37/bin/python) #python bin dir
include_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)
安装python库
$ cd python
$ pip install .
运行测试程序
$ python test_stream.py
