Just be careful removing all leading digits if you have songs in your library by 3 Dog Night, 9 Inch Nails, or other artists who have chosen names starting with a number. Smilie

Also to add to Don's reply...

Just an observation.

Do we take it that the leading 5 digits only and NOT the whole filenames themselves determine the positional play.
if so what will happen if two or more end up with an identical 5 digit number from your random number generator?
If you have 9999 music files then this is a possibility...

What I understood from Rudic's post is that no matter what comes after alpha field. When it detects alphanumeric expressions, it will skip out the rest.

I am noob on nginx, as many other fields as an old guy Smilie
As far as I know, Nginx+rtmp reads those videos from directory but always with the same list order in hls mode. I could not have found a solution to shuffle playlist with nginx. With your help, I will rotate the list by changing pre-numbers so list will change.
Also nginx is better than ffmpeg's hls mode with low cpu and ram usage. That's why I prefer this way.


Thank you
