@anhuihbo 您好！提取码是：ta36（详见“”代码发布 | OpenASIC Code Release”板块中的帖子“ H.264 Video Encoder Demo [PYNQ]）”

目前正在研讀, 看起來是很標準的作法.

I'm getting some errors while doing the simulaion. The parameter 'bs_byte_cnt' isn't matching between f265 and h265 How can it be corrected I've attached the screenshot..Please tell 模拟时出现一些错误。 f265和h265之间的参数'bs_byte_cnt'不匹配 如何纠正 我已附上屏幕截图。.请告诉

H265ENC V2.0 Feature Improvement h265enc v2.0 a. Update the I/P prediction algorithms, and the hardware pipeline to improve the coding efficiency b. Fix the bugs in the previous version c. Check the RTL V2.0 by nLint, and fix the errors and warnings d. Meet the 400MHz synthesized by Design Complier，and fix critical path，warning e. IP Core V2.0 has been validated by the FPGA PreI – Intra mode decision a. Support CTU-level Rate control，based on the CABAC bit number to change the QP adaptively PosI – Intra partition decision a. Prediction for the partition decision is based on the original pixels b. The RD cost for the partition decision is based on the SATD and simplified rate estimation IME – Integer motion estimation a. Configurable IME parameters by the ime_cfg.dat, such as the search range, search center , and search shape b. Extend the search range to ±64 c. By the H-V SRAMs, the search direction of novel IME can be the slope d. By the Bit Truncation, the pixels bit depth is truncated into 4 bit from 8bit with only less than 1dB PSNR loss, but with great improvement on the area and power FME – Fractional motion estimation a. Support the SKIP and MERGE decision by the RD cost similar to the FME decision b. Fix the bugs in the interpolation REC – Reconstruction loop a． Support Intra CTU in Inter Frame by the costs from PosI and FME to decide I/P of current CTU b． Support the SKIP CU, where the prediction samples will be the reconstruction samples c． Rearrange the DCT RTL and fix the bugs DBSAO – Deblocking filter & sample adaptive offset a. Update the DB filter order and remove the transpose memory to reduce memory usage b. Support the SAO EO mode CABAC – Entropy coding a. Update the RTL and fix the bugs b. Support SKIP、MERGE、Intra CTU in Inter Frame and so on c. Remove the ROM in the previous version

请问，demo的内核没有正常启动，是uboot没有设置正确么？

Update to bs2hevc_v1.1 add command line options. type "-help" for more information

关于硬件开源，真的是太难得了。这些代码不止有研究学习的价值，善于利用，也有巨大的商业价值。范老师真的让人能感受到一个学者的风采。真的希望范老师的开源项目能够真正成为产学研合作的样板。希望一些有社会责任的企业，可以和实验室形成真正的合作。

这些视频有可用的英语字幕吗？我想学习，但我听不懂。请回复。谢谢！

introduction和user guide两个文档确实不能下载
