The first 5 minutes is missing | A video from CatchPlay

[CrymanChen]

Folks,

I'm posting to ask that why the first 5 minutes is missing.

As always, it is free to watch, only login needed and geo-restricted (Taiwan, Province of China)
URL: https://www.catchplay.com/tw/watch/0c098e72-669a-43a5-933a-c037462ee571

As shown above, the whole duration is 51:38


[Attachment 68029 - Click to enlarge]
But when I downloaded, and decrypted, it became 46:37

I do not think it's the key's problem, because the decrypted video can be played normally. Only the duration is wrong.
That is a 5-minute or so gap.

And I have tried searching the init.mp4 file, tried to concatenate the init.mp4 and the remaining video using

type init.mp4 v_dec.mp4 > video_compiled.mp4

but no success.

And I'm wondering if there are any solution.
Thanks.

During the whole process, I only used ytdlp to download.
And I have to say that I haven't met this situation before.

I'm afraid that there's one more question to ask.
I tried to download the subtitles also using the ytdlp:

ytdlp --write-subs --skip-download "......" --output subtitle.zh_TW.vtt

But the output file is a mp4?
I've set the output file as a vtt file...

Jezz...
The audio file is only around 4MB with a duration of 5 min 1 sec...
w... why?

OK, maybe another tool is a good idea.
Thank you @andrewzhong

YT-DLP doesn't get you very far, N_m3u8DL-RE is by far the best downloader i've found. Good for you as well, the git is written in chinese.
