ffmpeg error loading first segment; recording olympic videos from nbc and youtube


 
1 Attachment(s)
So i have been recording 1080p videos (saved fresh m3u8 links, so my downloads are usually in 15-minute segments, because I think the link expires, hence the HTTP 404 error) from youtube and nbc using ffmpeg.

This one error below is puzzling really, and I'm wondering is there is a solution at all......... Can somebody help?

--new to ffmpeg btw

"Invalid data" error is usually because the key i.d. strings have been tampered with in my experience, you havn't modified the .m3u8 files in any way have you?

There are 3 of them, all identical. The first is in the header but there are 2 others scattered throughout the segments. They must be preserved in the position they're found in or it won't authenticate.

No i haven't. I just followed your advice in another forum. Same process for all segments, until I encounter this error for a certain segment. It's annoying. I'm f*****g frustrated.

What if I just cut from a different part? Would it make sense?

Attachment contains the original m3u8 saved as text, as well as the edit. Error occurs at this point: range/5300078976-5303304687

You've lost the hlskey?id string at line 2596



your edit should start like this:



All HLS key i.d. strings must be preserved in order or it won't authenticate!

All HLS key string?
But I found only ONE place the key string, at the beginning of the .m3u8 file (line 5th) Otherwise the error message is same.

It's f...g annoying that I downloaded 2GB of data, and I can not use anything. :mad:
