[FFmpeg-devel] [PATCH 1/6] lavc/aarch64: new optimization for 8-bit hevc_pel_bi_pixels

[Logan.Lyu]

Hi Michael,

Thank you for reply.

I can't reproduce the error you mentioned...

I can apply patches to the ffmpeg master branch normally using 'git 
apply xxx.patch/.eml' or 'git am xxx.patch/.eml'.

By the way, I create these patches by /'git format-patch -s -o "../" 
--add-header "X-Unsent: 1" --suffix .eml --to ffmpeg-devel at ffmpeg.org -6 
--filename-max-length=100' /to generate .eml file.  And /'git 
format-patch  -4 --filename-max-length=100' /to generate .patch file as 
attachment to prevent encoding format problems in email files. These 
command should be OK, right?

Can you try these patches again? If the error still occurs, please tell 
me how it occurred then I will fixed it.
