### Region

Vietnam

### Example URLs

https://pops.vn/video/doraemon-s9-tap-417-hat-dau-ac-quy-bi-day-6013831da0c3120034d08bf6

### Provide a description that is worded well enough to be understood

Accessible in Vietnam only. Video consists of several ts segments but no m3u8 files that I can see.

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [X] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
