How can I batch/sequentially download m3u8 files using ffmpeg?

问题

I'm currently downloading m38u playlists individually using the following on Mac:

ffmpeg -i <"URL with m3u8"> -codec copy output.ts

If I want to do multiple files, I currently do it from separate Terminal windows.

What I would like to do is, in a single instance, tell ffmpeg to e.g. take URLs from a .txt file and download them in sequence, with a sequential output name for each (fine for them to all go in same output folder).

Sample code from m3u8 file:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-ALLOW-CACHE:YES
#EXT-X-TARGETDURATION:9
#EXTINF:8.333333,
segment00000.ts
#EXTINF:8.333333,
segment00001.ts
#EXTINF:8.333333,
segment00002.ts
#EXTINF:5.000000,
segment00003.ts
#EXTINF:8.333333,
segment00004.ts
#EXTINF:8.333333,
segment00005.ts

I certainly have homebrew installed - I'm a novice, so unsure whether that means I'm actively 'using' it to manage packages

The file with the list of of m3u8 addresses is currently located at /Users/username/Downloads/m38u hold list.txt and looks like this:

https://streaming.imvbox.com/media/2825/1280x800/1280x800.m3u8
https://streaming.imvbox.com/media/2298/1280x800/1280x800.m3u8
https://streaming.imvbox.com/media/2822/1280x800/1280x800.m3u8
https://streaming.imvbox.com/media/2821/1280x800/1280x800.m3u8
https://streaming.imvbox.com/media/2820/1280x800/1280x800.m3u8
https://streaming.imvbox.com/media/2088/1280x800/1280x800.m3u8

But so far this file is simply a place to store the links - I haven't used it anything other than to copy the links from.

So, I would save the following in your HOME directory as grabAll:

#!/bin/bash

HoldList="/Users/username/Downloads/m38u hold list.txt"

index=0
while read line ; do
    echo ffmpeg -i $line -codec copy output-${index}.ts
    ((index=index+1))
done < "$HoldList"

Note: If you use TextEdit, make sure to click menu option Format->Make Plain Text

Then you can start Terminal and run:

bash grabAll

and see if it is generating the type of commands you want. It doesn't currently do anything, it just says on the screen what it would do. If it looks good, you just need to remove the word echo from the 3rd to last line and run it again.

Sample Output

ffmpeg -i https://streaming.imvbox.com/media/2825/1280x800/1280x800.m3u8 -codec copy output-0.ts
ffmpeg -i https://streaming.imvbox.com/media/2298/1280x800/1280x800.m3u8 -codec copy output-1.ts
ffmpeg -i https://streaming.imvbox.com/media/2822/1280x800/1280x800.m3u8 -codec copy output-2.ts
ffmpeg -i https://streaming.imvbox.com/media/2821/1280x800/1280x800.m3u8 -codec copy output-3.ts
ffmpeg -i https://streaming.imvbox.com/media/2820/1280x800/1280x800.m3u8 -codec copy output-4.ts
ffmpeg -i https://streaming.imvbox.com/media/2088/1280x800/1280x800.m3u8 -codec copy output-5.ts
