Migrating from 0.11.x to 0.12+

[Quantumatum]

Hello, I'm a JS beginner and your work here has been super helpful in getting things up and running for me. I would very much like to migrate from 0.11.x to 0.12+ (official ffmpegwasm checklist here: https://ffmpegwasm.netlify.app/docs/migration) but I'm really struggling due to 'ReferenceError: Cannot access 'FFmpeg' before initialization', despite closely following the migration checklist and hours of trial and error. I'm not sure why I'm struggling so much as it appears very simple..

Do you have any plans to update this repository for 0.12+?

Thanks so much!

Hi again @Aniny21, for some reason I am facing an issue with v12 that I did not have with v11. So, my extension injects download buttons under reddit videos, and uses ffmpegwasm to create the video file before it's downloaded. I am struggling with the following exception, which is triggered during ffmpeg.load():

DOMException: Failed to construct 'Worker': Script at 'https://www.redditstatic.com/814.ffmpeg.js' cannot be accessed from origin 'https://reddit.com'. At i.load (chrome-extension://ljejfmmefhnpbpdhkhbbajpihfhnbdnm/lib/ffmpeg/umd/ffmpeg.js:1:2918)

I have written a more in-depth help request on the ffmpegwasm github repository, if you would like some more details: ffmpegwasm/ffmpeg.wasm#750

Do you know how I could fix this?

Many thanks

@QuantumForced
This problem is probably caused by ffmpeg.js trying to read files with relative paths.

I would like to fix this problem right now, but I have an urgent matter that may take some time to fix.

I will contact you again after the fix.
Sorry for the inconvenience.

Hi @Aniny21, thank you for your prompt reply and for offering to find a fix - I hope you find a solution to your urgent issue first.

Once you are ready to investigate, feel free to use this code I have prepared from my project:
https://github.com/QuantumForced/gc-ext-red-dl

It will inject a 'download' button next to all video submissions ( only on https://old.reddit.com/ ), you can also access the options page to enter a old.reddit url and see that in that case, the download is successful.

If you need anything else, please let me know!

Thanks again
