cdarlint / HLS_dvr.sh
Created Apr 27, 2017 — forked from John07/HLS_dvr.sh
A small script to make recording http live streams (HLS, those streams that work on iOS devices) nicer on a Mac. Script records the stream for a defined period of time and sends the user notifications if anything goes wrong and once it's done.

# required: ffmpeg (e.g. from homebrew), terminal-notifier from https://github.com/alloy/terminal-notifier
# you can schedule this with launchd to run e.g. weekly
# Specify in seconds how long the script should record (default here is 1 hour).
seconds=3600
# Date format for the recording file name
DATE=`date "+%d-%m-%y_%H-%M"`
# start ffmpeg recording
