Updates shouldn't appear in commit message. You can use "--annotate" of git send-email, then add your updates below "---" after sign-off. Thus the patch can be applied without updates. For example: https://patchwork.ffmpeg.org/project/ffmpeg/patch/20200909033956.27248-1-fei.w.w...@intel.com/ BTW, please indicate your patch version in the title. You should use '- -subject-prefix="PATCH v3"' in next time. > > In av1_spec.pdf page 38/669, there is a sentence below: > > if ( frame_type == KEY_FRAME && show_frame ) { > for ( i = 0; i < NUM_REF_FRAMES; i++) { > RefValid[ i ] = 0 > ...... > } > ...... > } > > This shows that the condition of invalidating current > DPB frames should be the coming frame_type is KEY_FRAME plus > show_frame is equal to 1.
