Expected behaviour

All videos download successfully.

Actual behaviour

The four videos above all failed at around 95% complete when using ffmpeg command-line tool. In the error log, it shows this warning message: "Application provided duration: {a huge number around 4294910296000} is invalid" and then the ffmpeg video conversion failed. This same issue was reported recently with a different video which now seems to download fine: https://github.com/Tyrrrz/YoutubeDownloader/issues/397

This same issue was reported recently with a different video which now seems to download fine: #397

This issue is not related to that one. #397 is about invalid subtitle language codes, while this one seems to be about mismatching track durations.

Crazy time debugging this, but it looks like the Chinese subtitles are broken. The last entry includes text content that is valid SRT, but contains incorrect length.

I assume these subtitles were added to the YouTube video by importing from an SRT file but something went wrong in the process.
