• How can some applications download and install ffmpeg just with one click ?

  26 septembre 2023, par Nacho B

  I have seen some applications that, as part of their setup process, offer a button to simply download and install ffmpg.

  


  How can this be possible without the user consciously installing it from the ffmpeg developers page or using a proper installer ?

  


  Can I simply store a finished build of ffmpeg to be downloaded and automatically copied to a specific location on the user's computer ?

  


  EDIT :

  


  I have found a related question with some answers, but none has been accepted (How to install ffmpeg and an app together on a Mac ?).

  


  It will be fine for me to just ask the user if they agree to download it. Then the app will download my ffmpeg build (stored in my website) to be copied in one specific directory to not interfere with other ffmpeg installations.

  


• Download live stream with changing chunklist/.m3u8 using ffmpeg or something similar

  23 juillet 2023, par Oliwer

  I've been trying to record a live stream from a website that change the .m3u8 link from time to time, sometimes it changes every minute and sometimes it changes 3 times in 10 sec. Is there a way to download the live stream in another way ? From my basic knowledge I have understood that they are using cloudflare for the stream.

  


  I know that it's possible to download since other people have been able to do it, but I am not able to find any information about it online.

  


  I've tried to find if there is a "master" file which could be able to give me access to the entire stream without any success.
I have been using -i "chunklist.m3u8" -c copy file.mkv
But every time it changes i have to type it all over with the new chunklist.m3u8

  


  Edit : When the change comes, a Website.com/json/liveApi_hls.asp followed by live-website.hscdn.com/pop_cast29/abc0122_P-00001_20230723223118/index.m3u8 ?%24NjW80dXNopqYmpuYn5qcmJmYm5qcusnWz82imZiYtaK1uKKezbueaEM%3D%24

  


  The change between the files are everything after .m3u8 ?
