我已经学会了如何通过“开放网络流”GUI 使用 VLC 下载视频，并且我已经这样做了数十次。我曾经不得不添加一个 http-referrer，但除此之外，我从来没有遇到过这个方法的太多麻烦。
现在我想下载这个视频，只有在登录该网站后才能访问。我确实有观看视频的适当凭据，请放心。我只想剪辑一个我喜欢的短场景 – 正如我倾向于做的那样。
自然，vlc 只会抛出 403 错误。
访问错误：HTTP 403错误
http 错误：本地流 1 错误：取消 (0x8)

考虑到此密码保护、必要的 cookie 和其他标头，我已设法通过curl 请求下载播放列表（
*.tscurl 'https://video-course.coolsite.com/video.m3u8' \
-H 'authority: video-course.coolsite.com' \
-H 'accept: */*' \
-H 'accept-language: en-US,en;q=0.9,de;q=0.8' \
-H 'cache-control: no-cache' \
-H 'cookie: CloudFront-Key-Pair-Id=ABCDEF; cf_clearance=LONGSTRINGCONTINUES; FUP_vid=12345; etc.' \
-H 'dnt: 1' \
-H 'origin: https://www.coolsite.com' \
-H 'pragma: no-cache' \
-H 'referer: https://www.coolsite.com/' \
-H 'sec-ch-ua: "Chromium";v="118", etc.' \
-H 'sec-ch-ua-mobile: ?0' \
-H 'sec-ch-ua-platform: "Linux"' \
-H 'sec-fetch-dest: empty' \
-H 'sec-fetch-mode: cors' \
-H 'sec-fetch-site: same-site' \
-H 'user-agent: Mozilla/5.0 etc.' \
--compressed
但是我不知道如何将那组参数翻译成vlc。我已经通过 GUI 以及
vlccvlc:cookie='…':set-cookie='…':http-cookie='…'这就是我得到的：
cvlc 'https://video-course.coolsite.com/video.m3u8' \
:???='video-course.coolsite.com' (authority) \
:???='*/*' (accept) \
:???='en-US,en;q=0.9,de;q=0.8' (accept-language) \
:???='no-cache' (cache-control) \

:???='cors' (sec-fetch-mode) \

研究
我最终通过curl下载了
*.m3u8*.ts$ cat segment1_0_av.ts segment2_0_av.ts segment3_0_av.ts > all.ts
$ ffmpeg -i all.ts -acodec copy -vcodec copy all.mp4
虽然我无法告诉 GUI 加载多个本地文件并将其保存到单个文件，但 CLI 端的 VLC 也可以根据 此文档页面 执行此操作。我还没试过那个。
