Batch file loop for retrying to record a stream

[sebastian]

Hi guys,

I'd like to record unattendendly an m3u8 stream. During my last tries the stream went offline during its broadcast, but than went online again after a few minutes.

So I'd like to record it via a batch file loop, so that I don't have to restart it again:

@echo off
:start
ffmpeg -i http://streamlocation.m3u8 -c copy filename.ts
timeout 120
goto :start

This should work, but the batch file is missing an option to generate a new filename (maybe filename.ts added with a sequence number) each time the loop starts again. Anyone with an idea?

Best
Sebastian
