M1 Mac 下无法正确生成内嵌视频

[meetyan]

你好，在 M1 Pro 的 Mac 电脑下，按以下代码，能生成视频没报错。但里面通过 FFVideo 引入的视频是空白的，有什么办法可以解决呢？

同样的代码，在 windows 和 intel mac 都正常。

依赖版本：

• ffcreator - 6.3.3
• ffmpeg - 4.4.1
• node - 16.13.0

const { FFScene, FFCreator, FFVideo, FFText } = require('ffcreator')
const path = require('path')

const width = 540 * 2
const height = 960 * 2

const cacheDir = path.join(__dirname, './cache/')
const outputDir = path.join(__dirname, './output/')
const outputFilePath = outputDir + `output.mp4`

const creator = new FFCreator({
  cacheDir, // 缓存目录
  outputDir, // 输出目录
  width, // 影片宽
  height, // 影片高
  fps: 30, // fps
  threads: 20, // 多线程(伪造)并行渲染
  defaultOutputOptions: null, // ffmpeg输出选项配置
})

const scene = new FFScene()
scene.setBgColor('#000000') // 设置背景色
scene.setDuration(20) // 设置停留时长

const newText = new FFText({
  text: '这是一个标题',
  x: width / 2,
  y: 400,
  color: '#ffffff',
})
newText.setColor('#ffffff')
scene.addChild(newText)

const video = new FFVideo({
  path: path.join(__dirname, './videos/output.mp4'),
  width,
  height: 600,
  x: width / 2,
  y: height / 2,
})

video.setAudio(false)
video.setLoop(true)
scene.addChild(video)

creator.addChild(scene)
scene.start()
creator.start()
creator.output(outputFilePath)

creator.on('complete', res => console.log(res))
creator.on('error', err => console.log(err))
creator.on('progress', e => {
  console.log(`FFCreator progress: ${(e.percent * 100) >> 0}% - output`)
})

Please upload your project

When I generate the video.js from the examples project it doesn't display the video but the sound from the video is there.

When I launch the example ( Number 8 ). This is the log:
