SharedArrayBuffer is not defined & SyntheticBaseEvent
3 juin 2024, par Dain Parkthank you for your help with my problem.


I am using FFmpeg.wasm on Next.js to compress videos when users upload them. I then send the videos to a server and save them on AWS S3. For the client side, I'm using Next.js.


To solve the error "SharedArrayBuffer is not defined", I added the following code to next.config.mjs :


/** @type {import('next').NextConfig} */
const nextConfig = {
 reactStrictMode: false,
 async headers() {
 return [
 {
 source: '/(.*)',
 headers: [
 {
 key: 'Cross-Origin-Opener-Policy',
 value: 'same-origin',
 },
 {
 key: 'Cross-Origin-Embedder-Policy',
 value: 'require-corp',
 },
 ],
 },
 ];
 },
};
export default nextConfig;


Here is the code I'm using for video compression :


import { createFFmpeg, fetchFile } from '@ffmpeg/ffmpeg';
const ffmpeg = createFFmpeg({ log: true });

export const compressVideo = async (file: File): Promise<blob> => {
 if (!ffmpeg.isLoaded()) {
 await ffmpeg.load();
 }

 // Write the file to FFmpeg's filesystem
 ffmpeg.FS('writeFile', 'input.mp4', await fetchFile(file));

 // Run the ffmpeg command to compress the video
 await ffmpeg.run('-i', 'input.mp4', '-vf', 'scale=1280:720', '-b:v', '1M', '-c:v', 'libx264', '-preset', 'fast', '-crf', '28', 'output.mp4');

 // Read the output file from FFmpeg's filesystem
 const data = ffmpeg.FS('readFile', 'output.mp4');

 // Convert the output to a Blob
 const compressedVideo = new Blob([data.buffer], { type: 'video/mp4' });

 return compressedVideo;
};

</blob>

This works well, but after that, I got this error : SyntheticBaseEvent on the video tag.


Can anyone help me resolve this issue ?

libx264 encoder error in ffmpeg android build
26 décembre 2013, par kerim yucelRight now, I have a ffmeg build script which recognizes libx264 and compiles succesfully. I have also compiled x264 and obtained libx264.a library. Both ffmpeg and libx264 are built from source. I can build ffmpeg without libx264 succesfully as well. Below you may find my script which tries to build ffmpeg with libx264.

build_oneAbove script doesn't give me libx264.a in ffmpeg output builds.Several other scenarios are as follows.
If I enable x264 encoder, I get undefined reference errors to some variables in x264.c (in libavcodec).
If I enable shared in ffmpeg configure, I get an error which says it can't cd to my prefix directory (no permission issues by the way).I am using latest releases of ffmpeg and x264 (cloned the git today) and ndk 7. Ubuntu runs on VM, installed on Windows 7. For further details about my adventure of ffmpeg/x264 porting to Android, you may refer here.
What should I do to use libx264 with ffmpeg ? I kept on trying this script with different configurations, removed all ffmpeg x264 folders and reinstalled them, but to no avail.
Thanks a lot in advance.

Below is my x264 build script. It builds fine, gives me the static library and the headers.export ARM_ROOT=/home/mehmet/Android_NDK_r7b
