StreamCopy Alfred Workflow
Takes a valid video URL from the clipboard (mp4, hls, etc.), plays the video using MPV and writes a video file to disk.
-Uses applescriipting to run commands with iTerm2
-Provides popup user interface to select video quality
-Writes to folder ~/Movies
Requirements:
youtube-dl, ffmpeg, mpv, iTerm2 (installed with homebrew)
Issues:
The workflow creates a pipe between ffmpeg and mpv. Closing the window before the download has finished will result in a broken pipe i.e. when streaming from an hls playlist. This results in ffmpeg not writing the trailer for the mp4 file correctly. The file still plays in apps like IINA or MPV but Quicktime player does not recognize the format. Nor does Quicklook.
Solution 1: re-encode the video file with ffmpeg. Then Quicktime and Quicklook will have no issues playing file
Solution 2: Use ffmpeg built in streaming protocol zmq to stream to server on localhost then play with ffplay. Basic command for this looks somethting like:
ffmpeg -re -i input.m3u8 -c:v libx264 -c:a aac -f tee -map 0:v -map 0:a "output.mp4|[f=mpegts]zmq:tcp://127.0.0.1:5555"
then
ffplay zmq:tcp://127.0.0.1:5555
To Do: Incorporate above strategy into project as alternative method.

Thanks for the info. That makes a lot of sense.

Is there a way to allow Alfred to search for hidden folders with the file search menu? I would like to include ~/.config within the search result so I don't have to type it in directly. I tried adding ~/.config to the list of search folders but it didn't work. Thanks.

download this workflow from http://www.packal.org/workflow/record-iina
This is version 2.0 of previously named "StreamCopy" workflow
Updated commands to send encoding media file to iina-cli as stdin. Also now uses IINA's own youtube-dl binary.
This workflow takes a valid video URL from the clipboard, plays it in IINA, and writes the video file to disk.
Provides a dialog for the user to select video quality (the user enters the youtube-dl format code which get sent back into the script)
Writes to folder ~/Movies (modify the script to save anywhere you please)
Uses applescript to run commands with iTerm2.
Requirements: IINA.app, iTerm2 (installed with homebrew)
Issues: The workflow creates a pipe between ffmpeg and mpv. Closing the window before the download has finished will result in a broken pipe i.e. when streaming an hls playlist. This results in ffmpeg not writing the trailer for the mp4 file correctly. The file will still plays in apps like IINA or MPV with no issue. However, Quicktime player will not recognize the file. Nor will Quicklook.
Solution 1: I have resorted to re-encoding these files with ffmpeg. Then Quicktime and Quicklook will have no issues playing file
Solution 2: Use ffmpeg's built in streaming protocol zmq to stream to a server on localhost then play the file with ffplay.
Basic command for this looks somethting like:
ffmpeg -re -i input.m3u8 -c:v libx264 -c:a aac -f tee -map 0:v -map 0:a "output.mp4|[f=mpegts]zmq:tcp://127.0.0.1:5555"
then
ffplay zmq:tcp://127.0.0.1:5555
Caveat: Neither IINA nor MPV seem to use the zmq protocol so using this method, one is stuck with using ffplay
