你好！我这边编译了项目，运行了示例程序的yolo检测，结果如下：
1
这里用的是默认的MP4文件，硬解速度只比软解快一点，差别不大；我改成了本地的RTSP视频流后结果如下：
2
这里我只解码了100帧就退出了，如图所示硬解速度比软解还慢一点，我这边用的是NVIDIA GeForce 3090的显卡，请问一下这个结果正常吗？或者能不能给出个参考数据？

正常，代码里面其实应该把推理结果获取一下，保证推理也算在内才是对的。这个忘记改了。
硬件解码的效率你可以观察cpu的占用率和多路视频才能发现其牛逼之处

多路视频是批量解码，还是单独一个程序一个程序的独立解码

批量解码，开多个解码器

批量解码，开多个解码器

是多线程的开多个解码器，还是for循环那种多个解码器？

多路视频有案例吗？可以分享一下吗@shouxieai
