streamlit学习-如何播放HLS视频
- 一.效果
- 二.直播环境搭建(仅供演示)
- 1.生成m3u8
- 2.搭建http服务器(支持跨域)
- 3.验证hls(VLC播放 http://localhost:8000/playlist.m3u8)
- 三.streamlit demo
本文演示了streamlit如何实现hls直播[streamlit中嵌入html]
一.效果
二.直播环境搭建(仅供演示)
1.生成m3u8
ffmpeg.exe -i abc.mp4 -c:v libx264 -an -vbsf h264_mp4toannexb -f hls playlist.m3u8
2.搭建http服务器(支持跨域)
import os
import sys
import http.server
import socketserver
class HTTPRequestHandler(http.server.SimpleHTTPRequestHandler):def end_headers(self):self.send_header('Access-Control-Allow-Origin', '*')self.send_header('Access-Control-Allow-Methods', 'GET,POST')self.send_header('Access-Control-Allow-Headers', 'x-requested-with,content-type')http.server.SimpleHTTPRequestHandler.end_headers(self)
def server(port):httpd = socketserver.TCPServer(('', port), HTTPRequestHandler)return httpd
srv=server(8000)
srv.serve_forever()
3.验证hls(VLC播放 http://localhost:8000/playlist.m3u8)
三.streamlit demo
import streamlit as st #1.31.1
import os
import sys
import time
import streamlit.components.v1 as componentsdef main():# 设置标题,图标等st.set_page_config(layout="centered",page_title="HLS播放",page_icon=":shark:")st.write("演示HLS播放")html_content='''
