New :

You often want to save a video on your hard drive to be able to watch later on a travel when you don’t have access to internet. There is one way to do it on websites that uses HTTP Live Streaming HLS.

Update :

Quick method :

An easier method is to use directly the m3u8 file available by filtering “m3u8” in the developer Filter box.

Replace the m3u8 url in the following ffmpeg command :

ffmpeg -i url -c copy -bsf:a aac_adtstoasc 11.mp4

Let’s take for example an episode of “LES RECETTES POMPETTES” http://noovo.ca/videos/les-recettes-pompettes/alex-nevsky when using the developper option (F12) on the Network section we can quickly see that small 10 seconds transport stream video files are received from the streaming server http://v10-a.akamaihd.net/hls/618566855001/201701/5300522320001/618566855001_5300522320001_s-4.ts?pubId=618566855001&videoId=5300467502001

If we analyse the link we see the extension .ts, that is the 10 seconds transport stream. The file name ends with 4 that’s the 4th 10 second transport stream.

http://v10-a.akamaihd.net/hls/618566855001/201701/5300522320001/618566855001_5300522320001_s-4.ts?pubId=618566855001&videoId=5300467502001

If we look at the video duration on the website we see that it lasts 21 min we can than calculate the number of files to download 24*60/10 = 144 files.

With a small bash file we can loop trough the list of files and download them :

#!bin/sh
#Download transport stream files from server
server=http://v10-a.akamaihd.net/hls/618566855001/201701/5300522320001/618566855001_5300522320001_s-
extension=.ts
max=144
for i in `seq 1 $max` do wget $server$i$extension
done

Last step and not the least is to concatenate all the files to output them into a single transport stream of 21 minutes. For that task we can use ffmpeg concatenate function (you can get ffmepg by using sudo apt-get ffmpeg command ) :

ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.ts

or inline loop the current folder .ts files using :

ffmpeg -f concat -safe 0 -i (for f in ./*.ts; do echo file '$PWD/$f'; done) -c copy output.ts

The -safe 0 above is not required if the paths are relative.

The -i mylist.txt is a file text that contains the list of input files to concatenate it should be with the following format :

# this is a comment
file '/path/to/file1'
file '/path/to/file2'
file '/path/to/file3'

Finally the output.ts will be the name of your final file you should specify the output type .ts or another format .mkv
