1. Download the json-info with youtube-dl
2. The file will have a list of fragments that looks like:
"fragments": [{"path": "sq/4037/lmt/0000000000000000", "duration": 1.0},
3. Adding the missing fragments starting from 0 to the first number in the list. The /lmt/... part is unnecessary. It should look like this:
"fragments": [{"path": "sq/0", "duration": 1.0}, {"path": "sq/1", "duration": 1.0},...
4. Feed the new json file into youtube-dl
Obviously you can automate the json editing process.
