#ffmpeg and ffprobe android command line tools
FFMPEG(4.1.3 官网2019-07-05最新版本)
- ffmpeg日志回调接口
- ffmpeg增加监听百分比进度(需要获取转码后视频的总时间 具体看demo)
ffmpeg需要单例运行
如:转码mp4 CPU利用率80%以上 其它视频不低于60%间波动 (冬天暖手宝)
FFPROBE
- ffprobe 只实现了返回 json 回调
- ffprobe线程和ffmpeg线程独立运行
注意编解码器
如果编码器全开放 库文件就太大了
解码器全部放开了 但是编码器只有aac 和 libx264 所以大部分手机基本都支持了
--disable-encoders
--enable-encoder=aac
--enable-encoder=libx264
--enable-encoder=png
--enable-encoder=mjpeg
如果对编码器有特殊需求的可以重新编译库文件
重新裁剪编码器解决问题

implementation 'com.yyl.ffmpeg:ffmpeg_cmd:4.1.3'
目前支持的库 armeabi-v7a arm64-v8a 也可以参考build_android.sh脚本定制
ndk {
abiFilters "armeabi-v7a","arm64-v8a"
}
java Code
//ffprobe -v error -print_format json -select_streams v:0 -show_entries stream=width,height,index inputFile
String cmd = "ffprobe -v quiet -print_format json -show_format -i " +inputFile;
String json = FFmpegUtils.getInstance().execffprobe(cmd);
String cmd = "ffmpeg -h"
int code = FFmpegUtils.getInstance().execffmpeg(cmd,callback);
