在nwjs中找到了一样的报错，https://github.com/nwjs/nw.js/issues/6834 目前怀疑可能是ffmpeg.dll 没有打包到nw的问题
http://docs.nwjs.io/en/latest/For%20Developers/Enable%20Proprietary%20Codecs/
目前从https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases 下载了0.39.2-linux-x64.zip 替换掉 dist/lib下的libffmpeg.so 文件，上面功能就正常了

good, 现在最新的好像用的是nw.js 0.38.0 版本，符合的只有 https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases/tag/0.38.4 下载了替换掉就可以查看视频了
