使用 N卡配合FFmpeg进行视频编码有着并发数的限制,https://developer.nvidia.com/video-encode-decode-gpu-support-matrix#Encoder,可以看到,GeForce 系列各种显卡大部分限制为 3 路并发。这个限制貌似并不是硬件能力的限制,而是Nvidia为了让更多的人购买高端系列的显卡而做的手脚。
有同志已经制作了补丁,可以打破这一限制,https://github.com/keylase/nvidia-patch 。使用这个补丁后,我自己在公司服务器上使用,现在同时进行19路编解码,连续两周,还很稳定。

从哪里查看gpu解码的fps数据呢?

还有
假设:1080ti h264 的解码为200fps,然后它有一个解码核心,那么是不是可以理解为:解码fps为25的视频,它能带动8路视频?

如果超过了8路视频,代码是报错还是说继续解码,但是延迟会增加?
