内存泄漏：JavaScript-使用可转移对象将数组缓冲区传递给Web Worker

发布于 2025-02-04 02:33:14 字数 526 浏览 2 评论 0原文

因此，我将视频缓冲区（float32array缓冲区）传递到工作线程作为可转移对象，它发生在视频的每个帧（含义，连续的视频帧都传递给工作人员）。我进行了内存分析，并且工作人员线程保留了对象，似乎垃圾收集器没有启动。如何处理这种情况？我认为没有人可以在JavaScript中明确调用GC。

这是我如何将视频缓冲区传递给工作线程的代码片段：

this.worker.postMessage({
          command: 'SetVideoBuffer',
          data: {
            videoFrame: videoFrame
          }
        },
          [videoFrame.buffer]);

另外，我尝试将缓冲区设置为“ null”，这无济于事。

知道如何解决这个问题，这是镀铬的吗？请帮忙。

谢谢你！

So, I am passing video buffer(Float32Array buffer) to worker thread as a transferable object, it happens for each frame of the video(meaning, continuously video frames are being passed to worker). I did memory profiling, and worker thread is retaining the object, it seems garbage collector doesn't kick in. How to handle this case? I don't think one can invoke GC explicitly in JavaScript.

Here is the code snippet how I am passing video buffer to worker thread:

this.worker.postMessage({
          command: 'SetVideoBuffer',
          data: {
            videoFrame: videoFrame
          }
        },
          [videoFrame.buffer]);

Also, I tried setting the buffer at worker side to 'null', it didn't help.

Any idea how to resolve this, is this chrome thing? Please help.

Thank you!
