Re: [x265] [Bug]reconstruction yuv picture diff with HM decoder out
Hi, We've checked out for hash mismatch for all our hash clips with --rd 2. Can you share the source that caused a mismatch? That will help us identify the issue.

We are investigating the hash mismatch in rd 2 clip with our clips; would be good if you can share the source. 2. [Proprose] The x265 codec encodes video con-tent using a fixed quantization step, thus leading to a variable bitrate stream which may not be suitable for the many multi-media applications where a constant bandwidth is required. Therefore, maybe adaptive quantization step may be better. Adaptive Quantization is already implemented. You may use --aq-mode 1 (enabled by default in the medium preset).
