Date: Mon, 31 Mar 2025 19:49:32 +0200
Subject: [PATCH 08/12] avcodec/x86/h26x/h265dsp: Remove unused functions
The ff_h2656_put_{uni_,}8tap_hv{32,64,128}_8_avx2
and ff_h2656_put_{uni_,}4tap_hv{64,128}_8_avx2
functions were unused and have been removed.
This saved 3712B of .text here.
(ff_h2656_put_{uni_,}4tap_hv32_8_avx2 are now only
called from exactly one callsite (in
ff_hevc_put_{uni_,}epel_hv32_8_avx2) and could be inlined.)

Date: Mon, 31 Mar 2025 21:27:29 +0200
Subject: [PATCH 11/12] avcodec/vdpau: Only include mpegvideodec.h when used
mpegvideodec.h includes mpegvideodata.h which in turn contains
a "static const uint8_t *const ff_mpeg1_dc_scale_table =
ff_mpeg12_dc_scale_table[0]"; yet if mpegvideo is disabled,
ff_mpeg12_dc_scale_table is not available, yet a non-optimizing
compiler (like GCC with -O0) may emit ff_mpeg1_dc_scale_table
and therefore a reference to ff_mpeg12_dc_scale_table nevertheless.
Fix this by only including mpegvideodec.h if it is needed.
