The n8.1 pin's hwcontext_v4l2request.c deliberately blanks the transfer-formats list for AV_PIX_FMT_YUV420P10 sw_format (the mapping target for V4L2_PIX_FMT_NV15), so `ffmpeg -hwaccel v4l2request -vf hwdownload,format=p010le` on a Hi10P / Main10 input failed at filter-init with -22 EINVAL — even though kernel-side decode succeeded. 0002-nv15-to-p010-unpack.patch adds an inline NV15→P010 unpack (5 bytes per 4 samples, little-endian → high-10-of-16) inside v4l2request_transfer_data_from, exposes AV_PIX_FMT_P010 in transfer_get_formats for that sw_format, and rejects non-P010 destinations explicitly with ENOSYS instead of silently corrupting output via av_frame_copy on NV15-packed bytes. Verified on fresnel (RK3399, linux-fresnel-fourier 7.0-14): - 5-frame smoke test from issue #21 → exit 0, 13.8MB output - 20-frame mid-fixture decode → bit-exact HW==SW sha256 7d9b66d48d8f17b2281da1881c663ecc31722bb218aba1ae23bf28d07aa66b08 - 8-bit baseline (bbb_60s_720p.h264.mp4) still bit-exact HW==SW (no regression in the existing NV12 path) - Cross-device repro of original EINVAL on unpatched ampere (RK3588) pkgrel=4, confirming the bug is upstream-FFmpeg-side, not RK3399-specific Patch is upstream-able to Kwiboo's v4l2-request-n8.1 branch. Closes #21.

# FFmpeg + V4L2-Request hwaccel (stateless video decode on Rockchip,
|
|
# Allwinner, etc) for the Fourier umbrella. Tracks Kwiboo's long-running
|
|
# rebase of Jernej Škrabec's v4l2-request patchset onto ffmpeg release
|
|
# tags. Pins the branch tip to a known commit for reproducible CI builds;
|
|
# bump _commit when upstream picks up a fix we want.
|
|
#
|
|
# Why this fork instead of AUR ffmpeg-v4l2-request-git:
|
|
# - AUR is pinned to 6.1.1 with epoch=2, which is OLDER than Arch's
|
|
# stock 2:8.1-3 → installing it downgrades system ffmpeg.
|
|
# - AUR pulls X11/AMF/CUDA/FireWire/AviSynth/OpenMPT/Bluray — irrelevant
|
|
# for a Wayland + ARM + video-decode fleet.
|
|
# - AUR uses #branch=..., no commit pin. CI artifacts are non-reproducible.
|
|
#
|
|
# Encoders (libx264/libx265/libvpx/libdav1d) kept per Fourier fleet policy.
|
|
# X11, AMF, CUDA, FireWire, AviSynth, OpenMPT, Bluray, OpenMAX, JPEG-XL,
|
|
# Theora, XVid, rsvg, soxr, ssh, vidstab, modplug, SDL2, Vulkan, JACK, GSM,
|
|
# Speex dropped — not needed on the Fourier fleet. (No SDL2 means no
|
|
# `ffplay` binary; mpv covers interactive playback.)
