Hi,
My customer test the HEVC encoder (C66x_h265venc_01_00_00_44_ELF) on single C6678 chip. The detail test parameter please refer to attached encparam.txt. (1080p30 with 1Mbps,qpMax 40,qpMin20). If the test clip has big block movement or the background has gradual changing color, the quality is not good. Please refer to attached encode result enc1920x1080Hpayload_108.265.
Would you kindly check this and suggest how to improve the quality by configuration (Guarantee 30fps)?
Best Regards.
Marvin
