HLS/m3u8视频相关操作入门（ffmpeg）

本文主要是介绍HLS/m3u8视频相关操作入门（ffmpeg），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

mp4转ts

ffmpeg -i inputfile   -codec copy -bsf h264_mp4toannexb outputfile

ts转MP4

ffmpeg -i inputfile  -acodec copy -vcodec copy -bsf aac_adtstoasc  outputfile

hls(m3u8)下载并转mp4

ffmpeg -i https://xxx.xxx.xxx/xxx.m3u8 -c copy -absf aac_adtstoasc output.mp4

ts（多个ts文件）转mp4

ffmpeg -y -f concat -i mp4list.txt -c copy asddaas.mp4

其中，mp4list.txt文件内容格式如下：

mp4list.txt文件内容： 
file “1.ts” 
file “2.ts” 
file “3.ts”

下载hls中的多个ts片段

#获取所有ts片段的url
def getAllUrl(url):url_list = []html = requests.get(url)file_url = html.text.split('\n')for url in file_url:if len(url) > 0 and url[0] != '#':url_list.append(url)return url_listurl = 'https://xxx.xxx.xxx/xxx.m3u8'
file_path = './' 
file_url = getAllUrl(url):  
base_url = '/'.join(url.split('/')[0:-1])
for u in file_url:url = base_url + '/' + uprint('url', url)if os.path.exists(file_path + '/' + u):continuewith open(file_path + '/' + u, 'wb') as f:f.write(requests.get(url).content)f.close()

多个ts片段合并

[shell]

for i in `ls *.ts`; do cat $i >> output.ts; done

[python]

import subprocess
read_file = ["1.ts","2.ts","3.ts"]
for i in read_file:str_c = 'cat ' +i+  ' >> ' + outputfile.strip()print(str_c)subprocess.getstatusoutput(str_c)
