Kurento 6.4.0（適用於Chrome）的自定義過濾器崩潰版本49.0.2623.75（64位）

Question

我正在使用Kurento 6.4.0和自定義過濾器。我正在嘗試一個修改版的羣組調用示例，它可以在Firefox瀏覽器上正常工作，但在與Chrome瀏覽器版本49.0.2623.75（64位）連接時，KMS會崩潰。

以下是從日誌文件中的錯誤：

是否有與瀏覽器版本的任何問題，或者是有什麼錯我的KMS過濾器，這是造成這個崩潰？

Answer 1

看來，問題是你的VADCustomFilterImpl它試圖UNREF的東西，可能是已經發布的析構函數。

編輯：

如果要存儲的未來進程緩衝區，你應該叫gst_buffer_ref同時存儲和gst_buffer_unref當你爲了釋放完成。
