Pardon me not following the bug report layout, but I believe this is more of a general bug than a specific one. If need be, I will still provide files should you require them.

I was downloading the Instagram Livestream of a user earlier and later I noticed that the download duration was wrong and therefore the missing approximation was wrong too.

However, the temporary video file came out to be 18:01 in length while the temporary audio was 18:00. I came to realize these lengths are false because the video cuts out earlier than the length because footage is missing. The merged video's duration is true to length at 17:50. However, the log said the download duration was 17:26, but that's not the case here with the merged segments.

Furthermore, I used the method to get the missing segments by using #121 successfully and restored 10 seconds. This brought the original result of PyInstaLive's livestream recording from 17:50 to 18:00 which was more in-line with the temporary file. Additionally, this result is much closer to the logged airtime of 18:05.

This is the case for not only this recording but plenty of others as I came to find out.

This happens when the stream enters the "interrupted" e.g. the livestreamer loses internet connection temporarily or minimizes Instagram app. During these moments no video is being streamed but the total airing time does not account for this and simply measures the elapsed time between the start of the stream and the current time.
