This series contains fixes and improvements for the hantro H264 decoder. Patch 1-6 fixes issues and limitations observed when preparing support for field encoded content. Patch 7 introduce new DPB entry flags that is used to signal how a reference frame is referenced. This information is needed to correctly build a reference list for field encoded content. Patch 8 adds bits to handle field encoded content, this is a rough patch and should be reworked with proper code style and formatting. Please get back with feedback on how to improve this. The following samples from [1] are now playable with patch 1-8 - H264_1080i-25-interlace_Kaesescheibchen.mkv - H264_10_1080i_50_AC3-Astra19.2_ProSieben_HD.ts - big_buck_bunny_1080p_H264_AAC_25fps_7200K.mp4 - h264_tivo_sample.ts The rest of the patches refactors G1 H264 code to more closely match the code generated by my rockchip-vpu-regtool at [2] and then adds support for H264 decoding on RK3399/RK3328 using the VPU2 block. This code is early work and needs proper code style and formatting, I just wanted to share the early work and get some initial feedback.
