是否有编解码器或编解码器包？ -- audio 领域 和 video 领域 android 相关 的问题

I have a video without any problem in Windows (with K-Lite Codec Pack, but probably it is not important).

I copied it into my smartphone with OS Adroid 5.0.2, and I indeed need some codec/codecs for playing it back, because I got a message that is not possible to playing it back.

I know that there are media players with embedded codecs but it is not a solution for me - I want playing it back with my favorite media player.

Converting it to another (supported) format is not acceptable, too.

Is there a codec for it? Here is MediaInfo output for it:

If you use an Android device with Google Play Services, Google has a document which requires what the device MUST have:

Current Android Compatibility Definition Document - 5.3 Video Decoding

As you have an Android 5.0 device this document would apply:

Android 5.0 CDD - 5.1.3 Video Codecs

Note that your video file is an AVI container format which isn't listed so it would be up to the manufacturer to support that format or any additional codecs.

As to why can't you just add a codec see this StackOverflow post:

Adding video codec to Android

The short version is that codecs are in ROM and you can't write to ROM unless you are creating your own Custom ROM.

TL;DR: No, you can't add codecs. Use a third party player which supports your format or convert your video to a supported format (both of which you've rejected).
