puppeteer-recorder：流被破坏后无法调用write

我使用puppeteer-recorder，代码是：

await record({
    browser:    browser, 
    page: page, 
    output: '8output.webm',
    fps: 8,
    frames: 8 * 10, 
    prepare: function (browser, page) {}, 
    render: function (browser, page, frame) {} 
});

但运行错误：

Error [ERR_STREAM_DESTROYED]: Cannot call write after a stream was destroyed
at doWrite (_stream_writable.js:413:19)
at writeOrBuffer (_stream_writable.js:401:5)
at Socket.Writable.write (_stream_writable.js:301:11)
at /data/pupp_test/node_modules/puppeteer-recorder/index.js:72:12
at new Promise (<anonymous>)
at write (/data/pupp_test/node_modules/puppeteer-recorder/index.js:71:3)

at processTicksAndRejections (internal/process/task_queues.js:82:5)
at async /data/pupp_test/test2.js:22:5

我的ffmpeg配置为“ --enable-libvpx --enable-libvorbis”

  ffmpeg version 4.2.2 Copyright (c) 2000-2019 the FFmpeg developers

如何解决错误（流被破坏后无法调用写操作）？

解决了。

重新安装libvpx。请参阅https://trac.ffmpeg.org/wiki/CompilationGuide/Centos

git clone --depth 1 https://chromium.googlesource.com/webm/libvpx.git
cd libvpx
./configure --disable-examples --disable-unit-tests --enable-vp9-highbitdepth --as=yasm
make
make install
