[FFmpeg-devel] [PATCH] avcodec/cuviddec: Add handling HDR10+ sidedata on cuviddec.

[김윤주]

Does native decoder refer to hevc (hevcdec.c)? 
I tried using hevc and in environments with low CPU performance, hevc_cuvid
was much faster. 
So, I used hevc_cuvid for decoding but encountered an issue where HDR10+
sidedata did not exist. 
That's why I wrote this patch. 

I thought that the original content's sidedata should be preserved even
after decoding regardless of which decoder is used. 
And I thought hevc_cuvid was the only way to get Nvidia hwaccel support. 
If I'm mistaken about anything, please let me know. 

Also, is it correct to respond to your comments like this? 
It seems quite different from the format you sent. 

Apologies, as I'm still relatively new to the FFmpeg community and have a
lot to learn. 
Any additional guidance would be greatly appreciated.

Why? Can't you just use the native decoder with nvdec hwaccel?
