Q&A: How is VPU Latency on i.MX6
Q&A: How is VPU Latency on i.MX6
Q: What is latency figures for the VPU to decode
Device: i.MX6Q
OS: Linux
Resolution: 1920x1080(HD)
Frame rate: 30 FPS
Function: Overlay messages.
Input/Output: 8 bit / YUV 4:2:0 / NAL stream
Profile level: 4.1. Constrained Baseline. I and P frames support.
A:
It depend on the syntax in H.264, includes num_reorder_frames,max_dec_frame_buffering,num_ref_frames,MaxDpbSize,etc. for start latency: it cover vpu driver loading, allocate buffers, init, decoding the first frame less than 100ms on iMX6/Linux.
