Mirror of arch/ffmpeg-v4l2-request-fourier into the Debian tree.
Same source pin (Kwiboo v4l2-request-n8.1 @ b57fbbe), same 2
patches (libudev-bypass-fallback + nv15-to-p010-unpack), same
configure flag policy (drop X11/AMF/CUDA/Bluray/Vulkan/SDL2/etc.
per Fourier fleet focus).
Output: single .deb at /usr/bin/ffmpeg + /usr/bin/ffprobe +
/usr/lib/aarch64-linux-gnu/libav*.so.61. Conflicts/Replaces
the stock Debian ffmpeg + per-lib packages; takes epoch 2
(matches Debian's existing ffmpeg epoch).
Provides 'ffmpeg -hwaccel v4l2request' + '-hwaccel drm' routes
that drive rkvdec / hantro / cedrus / rpi-hevc-dec /
daedalus_v4l2 stateless decoders through libavcodec's hwdevice
DRM path, bypassing libva. Required by mpv-fourier and
firefox-fourier as their backing FFmpeg; also the kdirect
bit-exact reference for libva-v4l2-request-fourier validation.
NOT strictly required for the VAAPI-only path on
daedalus-v4l2 hosts (stock Debian ffmpeg + libva-v4l2-request-
fourier covers that). Install only when going firefox-fourier
or kdirect.
