Subject: [PATCH] fix(transcode): conditionally fix VAAPI filter order for HEVC
(tested on Haswel) l Places 'format=nv12' before 'hwupload' in the VAAPI
video filter chain only when the input codec is HEVC and hardware decoding is
disabled. This resolves filtergraph/driver issues observed on Intel Haswell
GPUs when transcoding HEVC->H.264 VAAPI via software decode, ensuring the
encoder receives the expected NV12 surface. Retains default filter logic for
other codecs. Addresses issues discussed in GitHub issue #18103
