Description

VODs on the Trovo.live site are not downloading due to a 403 Forbidden error. I have included a valid VOD URL in the log above, but I haven't had success with any VOD on the site.

It seems that the test case URL in the trovo.py extractor code (https://trovo.live/video/ltv-100095501_100095501_1609596043) is returning 404 and could also be updated.

The API URLs used in the extractor aren't working. No similar APIs seem to be called when loading a video in the browser. However most of the extracted data, apart from the comment list, is available in the non-JS webpage.
