如何在Android中使用ffmpeg文件从URI播放音频文件

Question

HI all,

I am working on playing audio from URI using ffmpeg shared library in android.

I configured android-ndk and added ffmpeg shared library to project and able to compile the project using cygwin.

In ffmpeg library i see ffmpeg.c file, i donot know how i can use this file to implement audio player in my activity.

Please help me on this issue.

Thank you in advance

Answer 1

First, Use ffmpeg to open the URI and read frames and decode to raw PCM data, you can take a look at ffplay.c about the decoding part.

Next, using the Android AudioTrack class to play the raw PCM data, there is a tutorial: fun with audiotrack

Good luck!
