[FFmpeg-devel] [PATCH v7 1/2] lavc/svt_hevc: add libsvt hevc encoder wrapper.

[Sun, Jing A]

I just searched my inbox again but failed to find that email of question you mentioned.
Could you please elaborate your request? What is the preservation for and how is it expected to work?

Regards,
SUN, Jing

base on patch by Huang, Zhengxu from https://github.com/intel/SVT-HEVC

V4: - Fix the build error with new API in PR#52
    - Fix the encoding hang issue by API change in PR#52
    - Fix the last frame dropping issue
    - Fix the invalid parameter causing segmentation fault issue
    - Add the support to svt hevc and av1 plugins coexistance
    - Add the VMAF optimized mode to "-tune"
    - Add the "-hdr" parameter

Apologies if i missed your reply but i think my question was not answered

Is there any way to preserve the color matrix/primary/transfer properties during encoding?

Thank you
