Hi ,

@asdasdqqq :

It is a batch file ( used under Windows ) .
Open a text editor paste the lines and save as blabla.bat .
Note : in the same directory where is stored ffmpeg .

1) keep the windows open

@echo on
ffmpeg ...
pause
:fin

you could also have
2) close the windows automatically

@echo off
ffmpeg ...
:end

Cheers .

I think he is asking how to assemble all of the .ts file segments if he downloads all of them independently of ffmpeg.

One way to do that is download the m3u8 file, and then the key file from the url found at the beginning of such m3u8 file. Then download all of the .ts segments by whatever method.

Then put the m3u8 file, the key file, and all of the .ts files into a folder. Edit the m3u8 file so the key reference is not a url, but instead just the key's filename.

The run ffmpeg with the edited m3u8 filename as the input, rather than the url.

Hi ,

As he tolds :
> when i use this code in ffmpeg ...

I have ansered , thinking
_ he knews how to use ffmpeg
_ using ffmpeg , no more instructions ( for assembling ) are needed . It's the best !!!

Just waiting the end of the process .
And convert to .mp4 eventually .

Cheers .

@ponens, please help me with this problem. I know this topic is from 2014 but is actual for me
I downloaded all ts files, index.m3u8 file and hq.m3u8 file but I don't find... the key file.
In the hq.m3u8 file is not an address to a key file but: #EXT-X-KEY:METHOD=AES-128,URI="key:content=SV-00007652"

The index.m3u8 file content:
==========
#EXTM3U
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1562656,RESOLUTION=720x576,CODECS=" avc1.64001e,mp4a.40.2"
hq.m3u8
==========

The hq.m3u8 file content:
==========
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:11
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-KEY:METHOD=AES-128,URI="key:content=SV-00007652"
#EXTINF:10,
hq-0.ts
#EXTINF:10,
hq-1.ts
#EXTINF:10,
hq-2.ts
#EXTINF:10,
hq-3.ts
#EXTINF:10,
---------------
hq-136.ts
#EXTINF:0.75,
hq-137.ts
#EXT-X-ENDLIST
=============

You'll have to explain more about the environment in which you obtained the m3u8 file. Usually when the URI= is not a url, but instead some "xxx:" reference, then the host hls player is getting the key from some local source that the hls player has implemented and understands. This sort of implementation is very common with mobile app hls players, and also some flash based hls players.
