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<\/a>.<\/p>\n\n\n\n

Quick method :<\/h3>\n\n\n\n

An easier method is to use directly the m3u8 file available by filtering “m3u8”<\/em> in the developer Filter box.<\/p>\n\n\n\n

http:\/\/c.brightcove.com\/services\/mobile\/streaming\/index\/rendition.m3u8?assetId=5300522320001&amp;amp;pubId=618566855001&amp;amp;videoId=5300467502001<\/pre>\n\n\n\n
Replace the m3u8 url in the following ffmpeg command :<\/p>\n\n\n\n
ffmpeg -i url -c copy -bsf:a aac_adtstoasc 11.mp4<\/pre>\n\n\n\n

Let’s take for example an episode of “LES RECETTES POMPETTES” http:\/\/noovo.ca\/videos\/les-recettes-pompettes\/alex-nevsky<\/a> 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<\/a><\/p>\n\n\n\n
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.<\/p>\n\n\n\n
http:\/\/v10-a.akamaihd.net\/hls\/618566855001\/201701\/5300522320001\/618566855001_5300522320001_s-4.ts?pubId=618566855001&amp;videoId=5300467502001<\/pre>\n\n\n\n
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.<\/p>\n\n\n\n
With a small bash file we can loop trough the list of files and download them :<\/p>\n\n\n\n
#!bin\/sh\n#Download transport stream files from server\nserver=http:\/\/v10-a.akamaihd.net\/hls\/618566855001\/201701\/5300522320001\/618566855001_5300522320001_s-\nextension=.ts\nmax=144\nfor i in `seq 1 $max` do wget $server$i$extension\ndone<\/pre>\n\n\n\n
Last step and not the least is to concatenate all the files to output them into a single transport stream of 21 minutes. For that task we can use ffmpeg concatenate<\/em> function (you can get ffmepg by using sudo apt-get ffmpeg <\/em><\/strong>command ) :<\/p>\n\n\n\n
ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.ts<\/pre>\n\n\n\n
or inline loop the current folder .ts files using :<\/p>\n\n\n\n
ffmpeg -f concat -safe 0 -i (for f in .\/*.ts; do echo file '$PWD\/$f'; done) -c copy output.ts<\/pre>\n\n\n\n
The -safe 0 above is not required if the paths are relative.<\/p>\n\n\n\n
The -i mylist.txt is a file text that contains the list of input files to concatenate it should be with the following format :<\/p>\n\n\n\n
# this is a comment\nfile '\/path\/to\/file1'\nfile '\/path\/to\/file2'\nfile '\/path\/to\/file3'<\/pre>\n\n\n\n
Finally the output.ts will be the name of your final file you should specify the output type .ts or another format .mkv<\/p>\n\n\n\n
