# Instructions
|
||
|
|
#
|
||
|
|
# First, install ffmpeg and youtube-dl
|
||
|
|
#
|
||
|
|
# https://ffmpeg.org/download.html
|
||
|
|
# https://ytdl-org.github.io/youtube-dl/download.html
|
||
|
|
#
|
||
|
|
# To capture a stream at https://yoururl and save to a dated, named TS file:
|
||
|
|
#
|
||
|
|
# bash capture.sh https://yoururl streamfilename
|
||
|
|
#
|
||
|
|
# Will create file streamfile_STARTDATE.ts and streamfilename.txt containing stream metadata.
|
||
|
|
#
|
||
|
|
# To capture stream and convert to an MKV file after:
|
||
|
|
#
|
||
|
|
# bash capture.sh https://streamurl streamfilename "convert"
|
||
|
|
#
|
||
|
|
# Will create TS file and streamfile_STARTDATE_to_FINISHDATE.mkv after capture complete.
|
||
|
|
#
|
||
|
|
# Note: Since this is capturing from a M3U8 stream you may end up retrieving more of earlier
|
||
|
|
# parts of the stream than the metadata will indicate. This will depend on the service
|
||
|
|
# you are capturing from.
