2017.3 Zynq UltraScale+ MPSoC VCU: Multistream decoder > 4 FULL HD instance fails with memory allocation errors in Linux

描述

In the 2017.3 Zynq UltraScale+ MPSoC Video Codec Unit (VCU), device memory consumption at various software levels (gstreamer, OMX and control software) is higher than the theoretical values.

This results in memory allocation failure if there are more than 4 instances of the Decoder.

解决方案

To resolve this issue, limit the multistream count to 4 1080p30 or increase the CMA size accordingly to support 8 streams.
