I'm trying to record the contents of the screen using mediarecorder and mediaprojection api. When I'm trying to change the video to HD on my device the recording fails but it works fine with 640 x 480 resolution. So my question is how could I get the supported video resolutions on a particular device? Cheers Jon

推荐答案

如果您唯一感兴趣的是API 21+，则可以使用

If your only interest is in API 21+, you can use the getVideoCapabilities() method.

CamcorderProfile 类自API 8开始就存在没那么有用.

The CamcorderProfile class has been around since API 8, but isn't quite as useful.

如果其他所有方法均失败，请反复尝试，测试每个所需的分辨率并标记无效的分辨率.

If all else fails, use trial and error, testing each desired resolution and flagging the ones that don't work.
