Automate things using yt-dlp, mp4decrypt and ffmpeg

[Jelov]

Hello, rookie here,

I manually download the .mpd file using yt-dlp, best-video.mp4, and best-audio.m4a
Then I decrypt them using mp4decrypt
Lastly, I join them using ffmpeg

Is there any way to do all these things automatically?
So that when I put the .mpd url and decryption key the remaining steps get completed automatically and produce the final output video.

See https://forum.videohelp.com/threads/407216-Decryption-The-Dungeon-of-Despair especially the second post for examples. A few other users here are posing scripts too. Look at them and adapt to your own needs

If you insist on using yt-dlp then I'm not sure, but N_m3u8DL-RE does all that (when using the needed parameters)

Okay I'm ready to adapt to new things. Kindly tell me the procedure I will try that out.

Thank you so much brother N_m3u8DL-RE has saved me a lot of effort. Really appreciate

I did compose this python script yonks ago. It's fairly generic: but it automatically does what you do. You run it. It asks for mpd. It'll download bestvideo & bestaudio using yt-dlp (of course, it does not select if best audio has AD, etc.), it'll ask for KEY#. Then it decrypts. It asks what name do you want to give file (yes, you can include spaces). then it'll place the decrypted file in a folder called Completed within the same folder that your python file resides:

####version (20230205-1)  do checks for dupe filename and illegal characters
####version (20230129-1)  replace aria2c with -N 6
####version (20221117-1)
#### remove y/n option to remove crap (it auto removes it now)
#### use shutil for moving crap to ./Throwaway and for removing ./Throwaway and its contents
#### allow you to call final file name to include spaces
#### at the end, it will now delete the Throwaway folder

thanks for the script
instead of using "mp4decrypt and ffmpeg" can u switch it to "mkvmerge and shaka-packager"
