【分享】MPSoC EV H.265编解码性能


MPSoC EV 系列支持H.265编解码。在规格中,1080p编解码都可以达到8路1080p30,总体相当于1080p240。使用2018.3 VCU TRD 实际测试,性能更好。按如下测试,编码每路的帧率达到达到45,总体相当于1080p350;解码总体相当于1080p390。编码时,每路的CPU负载在15%左右。解码时,每路的CPU负载在1%左右。
测试与单板负载、视频流特点相关,结果可能有稍微差别。

编码命令
ctrlsw_encoder -cfg vcu_hevc1k_latency_a1.cfg

解码命令
ctrlsw_decoder -hevc -noyuv -in vcu_hevc1k_latency_a1.265
