### Provide a description that is worded well enough to be understood

Many government agencies use the cablecast.tv platform for streaming live and recorded video. The video is broken up into four-second .ts file chunks.

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] 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
