我有旧版本的 Adob​​e Acrobat Reader，并且不想更新。但是，当我使用该程序打开 pdf 时，大约 10 秒后，程序崩溃（与打开哪个 pdf 无关）。当我的计算机未连接到互联网时，不会发生这种情况。

我尝试添加 Windows Defender FW 规则来阻止与目录中所有 .exe 文件关联的所有入站和出站流量C:\Program Files (x86)\Adobe。但这仍然行不通。

唯一有效的方法是阻止所有不符合规则的出站流量。

当 Reader 的所有 exe 都被防火墙阻止时，它如何设法连接互联网？

与此相关的问题：为什么 Windows Firewall Defender 无法在我的 Internet Explorer 上运行？

我正在尝试进行以下转换：

ffmpeg -i video.mp4 -map 0 -c copy -c:v libx265 -crf 30 -vf "scale=-1:\'min(720,ih)\'" -c:a libopus -b:a 44k -map_metadata 0 -loglevel error -hide_banner video.mkv

除了特定的视频外，这很好用。我得到以下输出：

[libx265 @ 00000000005a2940] Cannot open libx265 encoder.

当我用谷歌搜索第一个错误文本时，找不到一个结果，ffmpeg "Color Primaries must be unknown"

这是详细的输出：

我不是视频编码方面的专家，所以我真的不知道这一切意味着什么。可能与源文件有关。如何解决这个问题？提前致谢！
