kandi X-RAY | ffmpeg.wasm Summary
There are two components inside ffmpeg.wasm:. @ffmpeg/core contains WebAssembly code which is transpiled from original FFmpeg C code with minor modifications, but overall it still following the same licenses as FFmpeg and its external libraries (as each external libraries might have its own license). @ffmpeg/ffmpeg contains kind of a wrapper to handle the complexity of loading core and calling low-level APIs. It is a small code base and under MIT license.

QUESTION
I've built a React 17.0.2 application which has a dependency using "SharedArrayBuffer" (ffmpeg.wasm). This requires these Response Headers as per the docs:
...ANSWER
Answered 2022-Mar-14 at 16:36The CORS filter only handles the Access-Control-*
headers and does not do anything about Cross-Origin-*
headers.
If you wish to set Cross-Origin-*
headers, you will either have to manage that yourself, or submit a pull-request to the Tomcat project.
QUESTION
I was having the SharedArrayBuffer error as described in this other issue and to fix I added the cross origin isolation as suggested (also suggested here) by adding the headers

To make your application work again, you'll have to either copy and self-host those sources from your own origin, or bundle them as part of your application.

fixed the issue.
This is probably due to the fact that ffmpeg
needed the Vue instance to be already mounted in the DOM (in the way it works).
created()
is usually used for AJAX calls or things not so related to the Vue instance, and it being shown with the Composition API in their example gave me the idea of trying the mounted()
hook.
