Adds Kwiboo / Langdale's 2024-08 patches (0001-meson + 0002-vo-hwdec-drmprime)
so AV_HWDEVICE_TYPE_V4L2REQUEST flows through mpv's drmprime VO hwdec and
`--hwdec=v4l2request` engages against the dmabuf-wayland VO instead of failing
with "Could not create device". The matcher previously filtered on
AV_HWDEVICE_TYPE_DRM and rejected v4l2request even when libavcodec's hwaccel
returned a valid PRIME descriptor.
PKGBUILD: pkgrel 9 → 10, source[] picks up both new patches, prepare() applies
them before the existing 0001-vo_dmabuf_wayland cache-sync workaround,
meson build flag -Dv4l2request=enabled added so the new option compiles in.
Stacks on top of iter1 (713a856): the dma_buf cache-sync workaround stays
load-bearing for the existing vaapi_dmabuf and drmprime_dmabuf import paths;
this iter only adds the wiring for the drmprime VO's hwdec selector.

Subject: [PATCH 1/2] meson: add detection logic for v4l2request support
|
|
|
|
We will probably adjust this to look for a specific libavutil version after
|
|
v4l2request support is merged upstream, but this check is fine for now.
