ksanthosh82 commented 4 years ago

Hi, When I installed all dependencies and tried extracting the videos, I am facing below errors

<class 'TypeError'> 'NoneType' object is not subscriptable ....

Kind of tried skipping such none types but getting below error

Downloading using ffmpeg ffmpeg error: [hls @ 0x3876a80] Error when loading first segment

Can you please assist here?

Sadly I don't have access to the course on impartus, so I can't debug this myself. Read through this comment (and the entire issue too) and send the stored file here.
