【问题描述】:
在我的应用程序中,通过传递所选视频的文件路径,在不同 Activity 的 VideoView 中显示来自 sdcard 文件夹的视频或来自 Video intent 的新拍摄视频。
现在的问题是,
我已经在我的 2 台设备 LG Optimus Black and LG Optimus Me and it works 上测试了这个应用程序,就像魅力没有问题没有强制关闭。
现在当我在Samsung Fascinate 2.1 the video view shows the message "Can't Play Video" 测试这个应用程序时,无论我选择现有视频还是拍摄新视频。
请记住,该应用在上述 2 种设备上运行良好。
在 ShowVideo 活动中,我有上传视频的按钮,当我收到“无法播放视频”消息时,我能够从同一路径获取视频并上传它,并且可以在服务器上检查该视频侧面但视频视图没有播放该视频。
So, the Video Path of the SDCard is not the problem thats for sure.
also the Video are of .3gp or .mp4 format only so the format is also supported by android
.
我的问题是:
1) 何时出现“无法播放视频”消息? 2)解决方案是什么? 3) 我的申请中可能出现哪些错误?
这是我收到该消息时的 logcat 输出,但没有看到任何错误/异常。

如果你发现有什么不好描述的,请在下面评论。
附加细节(从 cmets 移出):
- 它们只有 1 分钟,而我在三星上测试并失败的最后一个只有 20 秒。目前,大小大多以 MB 为单位,不超过 20 MB。
- 该视频是从同一设备拍摄的,拍摄该视频后,我立即尝试在我的活动中以同样的方式显示其他已存储的视频也很好...实际上在上传该视频后,我可以看到该视频并且还可以下载
【问题讨论】:

我发现应用this answer 使我能够获得可播放格式的视频。 Here is what I did.

@Suragch 这是一个非常棒的答案,我已经赞成,但在问题的情况下,用户正在拍摄视频并播放它,那么如何在播放之前或保存时通过代码执行 ffmpeg 内容。选择的答案仍然是上述问题的赢家,因为除非您使用自己的媒体框架来捕捉和播放视频,否则没有解决方案。
