this should not exist on browser, right?

Hello,

I tried your sample for reactjs and custom some function like scale and crop a .mp4 video. Tested on my Macbook pro 2015 and use same input video, same command. But I got very different render speed when use browser and command line.

On Chrome browser:

frame= 68 fps=3.3 q=28.0 size= 0kB time=00:00:02.78 bitrate= 0.1kbits/s speed=0.135x

On command line:

frame= 554 fps= 52 q=28.0 size= 2560kB time=00:00:23.24 bitrate= 902.3kbits/ speed=2.26x

What should I do know to get higher render speed on browser? Thank you!

hello, I am trying to use this repo on my windows 10 machine, run yarn start with no error, but when I begin to access the website and click the button to begin, I get this error in the console:

[info] download ffmpeg-core script (~25 MB) from https://unpkg.com/@ffmpeg/[email protected]/dist/ffmpeg-core.js
getCreateFFmpegCore.js:22          GET https://unpkg.com/@ffmpeg/[email protected]/dist/ffmpeg-core.js net::ERR_BLOCKED_BY_RESPONSE.NotSameOriginAfterDefaultedToSameOriginByCoep 200

The initial problem faced running this app is an inability to successfully fetch from unpkg

However, disabling the cross origin leads to the SharedArayBuffer problem as described in installation. Does this mean the ffmpeg core needs to be loaded from same origin?

  const ffmpeg = createFFmpeg({
    corePath: "node_modules/@ffmpeg/core/dist/ffmpeg-core.js",

Doing so creates a problem that I originally faced trying this out in codesandbox

Hi,
can anyone help me understand why I get the error "Error: bad memory" after clicking on "start" button?

Uncaught (in promise) Error: bad memory at d296b078-c3e3-4526-99c1-2b484cf33c5d:23 at Object.load (createFFmpeg.js:64) at async doTranscode (App.js:13)

Thank you,
a.

Hey
I'm trying to convert Blob data from RecordRTC from webm to mp4. The script seems to be working and initialized, but React/NextJS throws a SharedArrayBuffer. Searching for that term gives me some answers about some vulnerability in SAB, but I don't understand what's up and down. It says there's a way to re-enable it though?
Is it a bug in ffmpegwasm or is there something deeper to it? As I'm creating a ReactJS website, I should be able to follow your example of your 'react-app' no?

Thanks

Was getting this issue playing around with the main repo and used this test one to verify I wasn't doing anything wrong. I cloned this repo, yarn, yarn start and clicked "start" in chrome and got these errors:

739f13dd-9e2d-4084-84d6-e533dfdc9ec9:1 worker.js onmessage() captured an uncaught exception: NetworkError: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'https://unpkg.com/@ffmpeg/[email protected]/ffmpeg-core.js' failed to load.
threadPrintErr @ 739f13dd-9e2d-4084-84d6-e533dfdc9ec9:1

package.json is using the updated "@ffmpeg/ffmpeg": "^0.8.1",

Hello - this is a super exciting project. Thanks for the React template. I'm having issues with trying this on Next.js and I suspect that would happen with this template as well.

ReferenceError: SharedArrayBuffer is not defined

From what I have read, this was a Firefox bug that is now happening in Chrome as well? Is there any resolution for this yet?

Thanks!

ffmpeg-core.js is loading and never executes..

its happening from. 30 minutes

i restarted several times but issue is same
