我已经尝试过未加密的破折号流在exoplayer2中的任何问题下都能正常工作..
但是我不知道如何解密流以及在没有加密的情况下完美无瑕。
我还没有尝试过使用exoplayer解密代码来建议这样做。
我已经使用ffmpeg和mp4box
intercept.mp4->是原始的源视频文件
//-视频和音频分离和解析速度脚本
ffmpeg -i intercept.mp4 -s 320x180 -c:v libx264 -b:v 500k -g 90 -an INVI_320x180_500k.mp4 &
ffmpeg -i intercept.mp4 -c:a aac -b:a 128k -vn INAU_128k.mp4 &

http://localhost:8085/test23/output e .mpd->加密的网址
http://localhost:8085/test23/output u .mpd->未加密的网址
未经加密的url与exoplayer代码完美结合,即使2小时视频也没有寻道时间
andriod的代码

需要建议解密片段并直接播放。
