使用test_gpu_decode_multi_processes.py脚本测试并发解码,最多只支持10路4K流
测试环境:
Linux服务器,4090显卡
input_video_path:从一个流媒体拉取的一条实时流(4K, 25fps, 2M码率)(流媒体的输出能力足够,与bmf程序在同一个服务器上)
num_processes:设置为10的时候,可以正常持续运行,设置为12的时候会随机有2~4路挂掉(timestamp=EOF)

input_video_path:换成720P的实时流时,num_processes设置为12路可以正常持续运行

测试过程中显存以及gpu使用率都充足

所以解码是在哪里有什么限制吗?感谢~

试试本地文件呢 最多可以支持多少路 这个感觉可能还是带宽的问题,不仅仅是网络带宽 内存显存交换也有性能瓶颈
