问题描述
鉴于从图库中拍摄的视频(设备支持的任意长度的视频)，我如何将第一帧提取为EncodedImage?谢谢

推荐答案
现在唯一的方法是通过本机代码.从历史上看，某些平台不支持抓取视频帧，并且在过去的7年中我们没有对此进行重新讨论.您可以对此提交RFE，但由于媒体很痛苦，现在我不确定何时开始实施RFE.
Right now the only way to do that is through native code. Historically some platforms didn't support grabbing a video frame and we didn't revisit that over the past 7 years. You can file an RFE on this but right now I'm not sure when we'll get around to implementing it as media is painful.
