问题描述

我目前解压，解码，编辑和重新编码的视频在Android上使用Media codeC和MediaExtractor在Android上。在这个过程中，我想给用户的进展的一些信息。我已经计数多少帧是如何提取，德codeD和连接codeD。为了计算一百分比和向用户展示的过程多远是，我需要的原始流中的帧的总数。但是，我无法找到在MediaExtractor的方法。

I am currently extracting, decoding, editing and re-encoding a video on Android using MediaCodec and MediaExtractor on Android. In the course of this process I would like to give users some information on the progress. I am already counting how many frames were extracted, decoded and encoded. In order to compute a percentage and to show users how far the process is, I would need the total number of frames in the original stream. However, I am unable to find a method in the MediaExtractor.

有谁知道我怎样才能得到一个视频帧的总数之前，我开始解压？

Does anybody know how I can get the total number of frames in a video before I start extracting?

推荐答案

您可以使用影片总长度和当前帧时间戳显示进度

you can use total video duration and current frame timestamp to show the progress

有关总帧数没有API可在MediaExtractor

no API for total frames is available in MediaExtractor
