如何在 HEVC 中提取每个宏块或切片的 QP？

Question

How can I get QP value per macroblock or slice from a encoded frame (encode by hevc hardware encoder)? I have tried some hevc bitstream parser like hevcexbrowser https://github.com/virinext/hevcesbrowser but it doesn't have access to CTU or parse slice body.

Answer 1

You can decode the bitstream using an open-source decoder, then modify that decoder to dump the information you need during its parsing. I'd recommend Hevc test Model (HM)
