Initial chromium-fourier shape on the chromium-builder@boltzmann LXD container we provisioned today. Approach is the 7Ji-style "tarball + system tools" pattern (no gclient/CIPD, the linux-arm64 dependency binaries don't exist anyway) but stripped of the MPP/X11/panfork specifics — chromium-fourier targets mainline kernel + Wayland + panfrost/panthor + V4L2 stateless on /dev/video0, not the vendor stack 7Ji's chromium-mpp targets. PKGBUILD highlights: - pkgver=147.0.7727.116 (current Chrome stable as of 2026-04-25) - gn args: use_v4l2_codec=true, use_v4lplugin=true, use_linux_v4l2_only=true, use_vaapi=true. The first three are the magic that unlocks V4L2VDA on Linux non-ChromeOS without source patches; if they're sufficient on their own, the chromeos-pipeline-bypass patch stays a no-op. - ffmpeg_branding="Chrome" + proprietary_codecs=true for H.264. - enable_widevine=false, enable_nacl=false to keep the tree small. - Currently development-shaped: prepare()/build() operate on a pre-extracted /build/chromium/src rather than makepkg-fetched source. Will switch to canonical source=(...tarball.xz) shape once the patches stabilise. patches/chromeos-pipeline-bypass.patch is a placeholder; the actual patch (if any) gets developed once we see what 7Ji's gn args do or don't unlock for us.

Subject: media/gpu: skip chromeos VideoDecoderPipeline on non-ChromeOS Linux
|
|
|
|
Placeholder. The patch will be developed against the actual chromium
|
|
147.0.7727.116 source tree on chromium-builder@boltzmann once the
|
|
tarball is extracted and we can read the exact code paths in:
|
|
|
|
- media/gpu/chromeos/video_decoder_pipeline.cc (PickDecoderOutputFormat,
|
|
Initialize, ImageProcessor setup)
|
|
- media/gpu/vaapi/vaapi_video_decoder.cc (ApplyResolutionChangeWithScreenSizes,
|
|
line ~1219 where "failed Initialize()ing the frame pool" fires)
|
|
|
|
The 7Ji-style gn args (`use_v4l2_codec=true use_v4lplugin=true
|
|
use_linux_v4l2_only=true`) MAY be sufficient by themselves to route
|
|
decode through the legacy V4L2VDA path entirely, bypassing the
|
|
chromeos pipeline without source patches. First build will tell us;
|
|
this file is the placeholder for the patch we'll need if it isn't.
|
|
|
|
# Empty no-op patch. patch -p1 < this won't change anything.
