您好,为啥我的qsv解码播放 比cpu解码播放 画面延迟高些 是因为qsv有缓冲区吗
你好,首先很感谢UP主,上传该份源码,对我刚开始接触windows视频开发有很大作用,感谢。
其次,在对比HWcodec中qsv硬件编码和X264软件编码,在码率、帧率、视频画面一样的情况下进行二者之间的比较,qsv相对于x264在CPU占用率(%10)变化不大甚至更高,GPU占用6%。
在OBS软件上面对比X264和qsv硬件编码,qsv的cpu占用明显降低。
OBS X264:画面静态:6.6% ,画面动态:19%
OBS qsv:画面静态:2.2% GPU : 13% ,画面动态:2.7% GPU:17~22%
请问基于FFMEPG的qsv有办法做到与obs在CPU上面相同的效果?
