视频不存在 #60

Closed xiaren2 closed 2 years ago

xiaren2 commented 2 years ago

3.4正常，3.5，3.6提示视频不存在，但是Camera1文件夹我根本就没动，卸载重新安装3.4，又能正常使用。

xiaren2 commented 2 years ago

安卓9，miui12

w2016561536 commented 2 years ago

有提示未授权吗，很长的一串

w2016561536 commented 2 years ago

请问问题解决了吗 三日后无回复默认已解决，将关闭issue

xiaren2 commented 2 years ago

打开vcam，提示"vcam:不存在替换视频"，没有很长的未授权啥的字符串。使用的vcam3.8

w2016561536 commented 2 years ago

是edxp吗

如果是全局模式的话，可能是因为其他应用程序没有权限读取相册，在私有目录下也未发现视频，但不影响正常使用。

xiaren2 commented 2 years ago

lsp，不是全局，只针对某些应用生效。反正自从3.4，体积缩小以后就不能用了。打开vcam会有那个提示，打来作用的app，也会有那个提示。3.4就正常。

w2016561536 commented 2 years ago

这个功能是3.5加进去的 检查一下目标应用在系统设置里的权限？

如果已经授权读取本地目录，那么请发一下xposed日志

模块日志就这么点。运行环境android 12，安装了存储空间隔离。

同样一个视频文件，更新到3.8之后，放在相机目录camera1下面能正常使用。禁止存储权限之后放在/Android/data/com.tencent.mm/file/camera1/virtual.mp4就无法使用了。

首先，请注意大小写，然后文件夹叫files，不是file（谷歌规定的） 日志里体现的错误将在下个版本修复

我使用了存储空间隔离这个软件隔离了微信。vcam认为微信使用了存储权限，跑去DCIM/Camera1下寻找virtual.mp4。而不是我在/Android/data/微信目录的files/Camera1下去寻找。 因为在实际应用场景中很有可能针对复数的app指定不同的视频。我个人建议app的主界面给用户两个选择 1：使用/DCIM/Camera1/virtual.mp4 2：使用/Android/data/[app包名]/files/Camera1/virtual.mp4

或者更极端一点的vcam采用自己存储目录，hook了app之后，在vcam存储目录下建立被hookapp包名的子目录，在子目录下放置需要的virtual.mp4和bmp文件。 缺点就是复数app使用同一个视频文件，会有重复文件占用空间。优点就是针对各个app hook的管理方便，无需判断其他app存储权限之类的

就是因为每一个应用独立设置太麻烦，所以才使用相册目录，因为读取相册权限还是比较低的。 但是VCAM创建的私有目录不行，除非软件向用户申请，否则不允许跨应用读取私有目录(安卓11) 至于你说的存储重定向，给重定向的目录底下搞个DCIM目录试下?

Atomos-X commented 2 years ago

唔，尝试了一下。因为使用存储空间隔离之后，默认软件就获得了访问存储空间权限。 实际上是存储空间隔离有选项开启软件访问相册的功能，不过我针对Tencent全家桶全部禁止访问了，单独开启授权/DCIM/Camera1/文件夹就可以。但是还是未解决复数app使用不同virtual.mp4的场景。如果切换使用的话需要不停的进目录改修改文件名和杀进程。

还有部分软件譬如telegram x，禁止文件和媒体权限在saved message下聊天框点击使用相机功能直接没反应，必须授权之后才能使用该功能，但是授权之后都在app包的files/Camera1下面就无法调用，强制去找了/DCIM/Camera1/virtual.mp4。

如果创建私有目录不可行的话，在/DCIM/Camera1下使用对应软件包名的视频文件：com.tencent.mm.mp4表示微信使用，org.thunderdog.challegram.mp4表示telegram x使用，这种方式是否可行？但又会存在一个问题，复数app使用同一个视频就需要两份一模一样的视频文件。不知道创建软链接能不能解决。

目前最方便的方法独立每个应用的视频就是ban掉存储权限 软链接这个不现实，sdacrd目录下貌似不可以，而且不是谁都有权限的。 之后可能会加一个手动切换。
