HLS视频相关操作入门（ffmpeg）

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_list
 
file_path = './' 
file_url = getAllUrl(url):  
base_url = '/'.join(url.split('/')[0:-1])
for u in file_url:
        url = base_url + '/' + u
        print('url', url)
        if os.path.exists(file_path + '/' + u):
            continue

        with 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)
