debian/ffmpeg-v4l2-request-fourier: new package

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.

+ffmpeg-v4l2-request-fourier (2:8.1+rfourier+gb57fbbe-1) bookworm trixie; urgency=medium
+
+  * Initial Debian packaging for the Kwiboo FFmpeg fork with V4L2
+    Request API hwaccel patches.
+  * Mirror of arch/ffmpeg-v4l2-request-fourier (same pin b57fbbe,
+    same configure flags, same 2 patches: libudev-bypass-fallback +
+    nv15-to-p010-unpack).
+  * Drop-in replacement for Debian's stock ffmpeg + libav*; takes
+    epoch 2 to win the apt version comparison.
+  * Required by mpv-fourier and firefox-fourier; not strictly
+    required for the VAAPI-only path on daedalus-v4l2 hosts (stock
+    libva + Debian ffmpeg works there).

+Description: FFmpeg with V4L2 Request API hwaccel (Kwiboo fork)
+ FFmpeg 8.1 patched with the V4L2 Request API stateless video decoder
+ hwaccel — Kwiboo's long-running rebase of Jernej Škrabec's
+ v4l2-request patchset onto FFmpeg release tags.
+ .
+ Provides 'ffmpeg -hwaccel v4l2request' / '-hwaccel drm' routes that
+ drive rkvdec / hantro / cedrus / rpi-hevc-dec / daedalus_v4l2
+ stateless decoders directly through libavcodec's hwdevice DRM path,
+ bypassing libva. Used by mpv-fourier and firefox-fourier as their
+ backing FFmpeg, and as the kdirect bit-exact reference in
+ libva-v4l2-request-fourier validation.
+ .
+ Drops X11/AMF/CUDA/Bluray/JACK/Vulkan/SDL2/Theora/XVid/Speex/JPEG-XL
+ per Fourier fleet policy (Wayland + ARM + video-decode focus). No
+ 'ffplay' binary; mpv-fourier covers interactive playback.
