try {
if (retriever != null) {
retriever.release();
Logger.d(TAG, "decode release path = " + path);
}

调用以上代码后，执行文件被持有命令
C:\Users\liera>adb shell lsof /camera/media/DVR20250514170442.mp4
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
om.voyah.vshare 9751 system 6r REG 253,400 78633319 1996 /camera/media/DVR20250514170442.mp4
发现文件fd被持有不会被释放，导致即使删除本地文件后，空间也不会释放，最终磁盘耗尽
