Arch Linux User Repository

I've gotten the YGGverse fork running with ffmpeg support after a fairly substantial patch and using ffmpeg-the-third:

dreieck, added you as maintainer, feel free to add dependency.

xdg-utils needs to be added as optional dependency since xdg-open is in the shabeng-line of the .desktop file.

According @dreieck stated:

==> Starting package()...
install: cannot stat 'gossip.svg': No such file or directory

I suggest to modify the line 41 from:

install -Dm644 gossip.svg "$pkgdir/usr/share/icons/hicolor/scalable/apps/$pkgname.svg"

to:

install -Dm644 "$srcdir/$pkgname/logo/gossip.svg" "$pkgdir/usr/share/icons/hicolor/scalable/apps/$pkgname.svg"

Please install the executable as /usr/bin/gossip, not /usr/bin/gossip-git.

Similar with the logo SVG file and the .desktop file: Name it gossip.*, not gossip-git.*.

Thanks for maintaining!

Error in package():

==> Starting package()...
install: cannot stat 'gossip.svg': No such file or directory

(it must be logo/gossip.svg, not gossip.svg.)

Regards!

Can you please add ffmpeg-git to the conflicts array?:

Information:
Build fails for me with

• error[E0004]: non-exhaustive patterns: `sys::AVPixelFormat::AV_PIX_FMT_D3D12` not covered,
• error[E0004]: non-exhaustive patterns: `sys::AVCodecID::AV_CODEC_ID_LEAD` and `sys::AVCodecID::AV_CODEC_ID_QOA` not covered and
• error[E0004]: non-exhaustive patterns: `sys::AVPacketSideDataType::AV_PKT_DATA_IAMF_MIX_GAIN_PARAM`, `sys::AVPacketSideDataType::AV_PKT_DATA_IAMF_DEMIXING_INFO_PARAM`, `sys::AVPacketSideDataType::AV_PKT_DATA_IAMF_RECON_GAIN_INFO_PARAM` and 1 more not covered.

↗ Upstream issue report.

pkgver() currently generates .r2069.gfe45e990 -- there is the official version missing at the beginning.

Version should be parsed from gossip-lib/Cargo.toml, not Cargo.toml.

Regards and thanks for maintaining!

• gossip-git in the provides array should be replaced with gossip=${pkgver}.
• gossip-git in the conflicts array should be replaced with gossip.
• Please move the cargo related download stuff out of build() into prepare() so that build() can run offline on already downloaded sources.

Regards and thanks for maintaining!
