Error and bulky, broken video #24

Getting this sometimes https://i.gyazo.com/35db5fd6f38b0a76931915b9df23f949.png When it happens the video file is huge and skips. Restarting mid-stream doesn't seem to help. Not a coder so don't expect much from me.

Can confirm. I will work on a fix.

Darkness4 commented 7 months ago

Fix will be pushed shortly.

The bug is caused by FC2 not sending timestamp. Expected:

Got:

https://us-west-1-media-worker1075.live.fc2.com/a/stream/v3/48843568/32/data/118607.ts

In the past, I put a simple skip (if timestamp not found, timestamp = now) and then looked for the next url to download. However, as fc2 doesn't send a timestamp at all, this doesn't work since it isn't able to find the next url. This causes my HLS downloader to download all the fragments again, which explains the size of the file (since fc2 sends 10 URLs per request, the file size has been multiplied by 10).

Whoops, I forgot to fix some logs. Wait for 1.6.3.
