因此，我使用 FFMPEG 在视频上应用多个覆盖，在 Windows 上，它对于各种大小和数量的覆盖始终能正常工作，但在 MAC 或 Linux 上，它会因重新初始化过滤器而产生错误。
假设我有一个 190MB 的视频和大约 182 个覆盖 PNG，它们将使用 filter_complex 进行覆盖。
for (let i = 0; i < pngPaths.length; i++) {
const start = Number(transcriptions[i].start).toFixed(2);
const end = Number(transcriptions[i].end).toFixed(2);
const overlayX = '0';
const overlayY = `0`;
filterComplex += `[${
i + 1
}:v] overlay=${overlayX}:${overlayY}:enable='between(t,${start},${end})'`;
if (i < pngPaths.length - 1) {
filterComplex += '[vout];[vout]';
}
}
我正在使用上述函数创建一个 filter_complex。
然后像这样运行 FFMPEG 命令：
const outputPath =
path.join(__dirname, '..') +
`/projects/${project.originalVideoFile}-output.mp4`;
this.appGateway.sendProgress(JSON.stringify(userId), 'progress', 0);
return new Promise((resolve, reject) => {
const ffmpegCommand = ffmpeg();
// Add video input
ffmpegCommand.input(videoPath);
// Add PNG inputs
for (const pngPath of pngPaths) {
ffmpegCommand.input(pngPath);
}
if (project?.user?.subscription?.plan?.id === 1) {
ffmpegCommand.input('watermark.png');
}
ffmpegCommand
.complexFilter(filterComplex)
.outputOptions('-c:v', 'libx264')
.output(outputPath)
.on('progress', (progress) => {
this.appGateway.sendProgress(
JSON.stringify(userId),
'progress',
Math.round(progress.percent),
);
})
.on('end', async () => {
“你可以忽略插座发射”
这在 Windows 上有效。但在 OSX 或 Linux 上处理时，会出现以下错误：
