[BUG] 部分视频获取流失败，仅输出音频轨（未登录，Win11 25H2）

[sadgea]

问题描述

部分 B 站视频在播放时只有声音，没有画面。按 Tab 键查看输入信息，完全没有任何视频条目，只有音频。

可以正常播放的视频示例：BV1aMEj62EdA
无法播放的视频示例：BV1f34y1r7y8

环境信息

• 插件版本：最新
• PotPlayer 版本：260630
• 操作系统：Windows 11 25H2
• B 站账号状态：未登录

复现步骤

1. 打开 BV1aMEj62EdA，画面声音正常，Tab 信息显示有视频轨。
2. 打开 BV1f34y1r7y8，插件界面依次闪过 480P HEVC → 480P AVC → ... → 360P流畅AV1，最后只剩 AAC 纯音频流，无画面，Tab 信息中无视频条目。

关键对比分析（AI分析）

两份完整日志见下方折叠块。

1. 最终获取到的流地址

• 正常视频（BV1aMEj62EdA）
  url: https://xy58x49x253x148xy.mcdn.bilivideo.cn:8082/v1/resource/.../38979504395-1-100022.m4s
  同时 PotPlayer 实际能播放画面，说明该 url 被正确识别为视频轨并传递给了播放器。

• 异常视频（BV1f34y1r7y8）
  url: https://cn-hnzz-cm-01-02.bilivideo.com/upgcxcode/.../517058166-1-100022.m4s
  日志中同样只输出了一条 url，格式与正常视频类似（-1-100022.m4s 通常为 DASH 视频轨），但插件最终没有将任何视频流交给 PotPlayer（Tab 信息无视频条目）。

推测：异常视频的这条视频轨地址可能因为 CDN、签名或返回的数据结构差异，在插件内部被判定为无效或被过滤，导致播放列表里只有音频轨。

2. CDN 与参数差异

项目	正常视频 (BV1aMEj62EdA)	异常视频 (BV1f34y1r7y8)
CDN 域名	mcdn.bilivideo.cn	cn-hnzz-cm-01-02.bilivideo.com
og 参数	og=ali	og=hw
mcdnid	50056342	无此参数
其他参数	traceid, sign 等	无 traceid

异常视频分配到了不同的 CDN 节点，且返回的链接缺少部分参数，这可能导致插件在解析时认为该视频流不可用。

3. 插件行为

两份日志都只输出了一个 url，没有同时输出独立的音频轨地址，且正常视频的日志也未输出音频轨。这表明插件的日志打印逻辑可能只输出了第一个匹配到的流，而实际传递给 PotPlayer 的流列表是内部生成的。异常视频的情况极有可能是插件在生成播放列表时，决定丢弃了这条视频流，只保留了音频流。

把potplayer换成老版本应该可以
