Mirror of arch/mpv-fourier into the Debian tree. Same source
pin (mpv 0.41.0), same 3 patches:
- 0001-meson-add-detection-logic-for-v4l2request-support.patch
- 0002-vo-hwdec-drmprime-add-separate-hwdecs-for-v4l2reques.patch
(Kwiboo + Langdale wiring for AV_HWDEVICE_TYPE_V4L2REQUEST
through drmprime VO hwdec — '--hwdec=v4l2request' actually
engages on dmabuf-wayland)
- 0001-vo_dmabuf_wayland-explicit-cache-sync-on-import-fd.patch
(iter1 of dmabuf-modifier-triage — explicit DMA_BUF_IOCTL_SYNC
on import fds; KWin-on-RK3566 dark-green chroma readback
regression fix on ohm. Root cause is the vb2_dma_resv RFC
upstream still pending.)
Depends on ffmpeg-v4l2-request-fourier (>= 2:8.1+rfourier) —
AV_HWDEVICE_TYPE_V4L2REQUEST only exists in Kwiboo's FFmpeg
fork; stock Debian ffmpeg doesn't have it.
Conflicts/Replaces stock mpv + libmpv2/libmpv1 — drop-in
replacement. Takes epoch 1.

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.
