Yes, I wrote a small program which can download the single segment files of a m3u8 video and calls ffmpeg to concat them to a video file. If I'll get further problems, I'll give yt-dlp a try. Thank you toby for that suggestion.

i assume you are using curl to get the m3u8 to get the urls and number of
fragments and then curl to get the fragments?

sounds like you are doing in fpc what yt-dlp is doing but in python

would you be up to posting the code you have written in fpc?  it would be interesting to test it



this is what yt-dlp is doing (from cli but same with sysutils.executeprocess in fpc)

No, I use class 'TFPHttpClient' to download each file.

I am sorry, no, for two reasons. 1st this program was a quick hack and is no recommendation to publish it. 2nd the program uses several common libraries, which I don't have the rights to publish them.

But if you are deeply interested, I could extract for you 1 procedure (which downloads 1 URL from type *.m3u8 into a small textfile and then extracts all needed segments into an array) and send it by PM to you.

But as said, that procedure would not compile (because of missing libraries) and all comments are in German.

Why don't you show us that routine? Do you want us to reinvent the wheel?
