@anon54163 To closer inspect (thus avoiding the described "importing random keys" trust of the terminal print) you can inspect the PKGBUILD. By doing so you will observe that the B4322F04D67658D8 key is in fact listed as the "validpgpkeys" and has been at least since the initial commit in 2018. Therefor they match.

For the current commit: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=ffmpeg-compat-57

and the initital commit from 2018 https://aur.archlinux.org/cgit/aur.git/commit/?h=ffmpeg-compat-57&id=8e7873f50cd9658457e67f5e0df79e5f7b0b4158

There is an error when validating ffmpeg-3.4.2.tar.xz. The PGP signature cannot be verified. I know I can import the key myself, but I'm not too comfortable importing random keys. This should ultimately not be necessary, like with other AUR packages.

I got the error regarding the x265 package, but I noticed I was trying to install ffmpeg-compat-57 from a different repo (chaotic-aur) instead of installing it from the AUR. Hope this helps someone.

@E3LDDfrK I'm not sure exactly why that error pops up, but rebuilding ffmpeg-compat-57 solves the problem. looking at the pkgbuild and deps, ffmpeg- doesn't explicitly require libx265.so=176-64, I think that's some leftover fluff from a previous release of this package.

@fabiocorbo Added an upstream patch to fix the compiler errors you mentioned.

ALso got this error:

installing x265 (3.2-1) breaks dependency 'libx265.so=176-64' required by ffmpeg-compat-57

The solution was just uninstall ffmpeg-compat-57 and reinstall it.

But any idea what I did wrong originally? I almost always installed packages with an AUR helper called pikaur. Never had the error before.

@fabiocorbo

Those are not errors. Those are warnings. If you had to interrupt the progress, that means it is building just fine, those are just warnings to let you know about things that could-and-should be addressed, but are not detrimental to the build/run of the package.

If the message says "warning:" You can ignore it unless it causes problems with the program running.

If the message says "error:" and the build process stops, You need to fix a problem before the program will build.

Hi, I'm trying to compile ffmpeg-compat57 both from pamac and from terminal, but I get errors like theese: CC libavdevice/alldevices.o In file included from ./libavutil/common.h:464, from ./libavutil/avutil.h:296, from ./libavutil/log.h:25, from libavdevice/avdevice.h:48, from libavdevice/alldevices.c:23: ./libavutil/mem.h:341:1: warning: ‘alloc_size’ attribute ignored on a function returning ‘int’ [-Wattributes] 341 | av_alloc_size(2, 3) int av_reallocp_array(void ptr, size_t nmemb, size_t size); | ^~~~~~~~~~~~~ CC libavdevice/alsa.o In file included from ./libavutil/common.h:464, from ./libavutil/avutil.h:296, from ./libavutil/log.h:25, from libavdevice/avdevice.h:48, from libavdevice/alsa.c:32: ./libavutil/mem.h:341:1: warning: ‘alloc_size’ attribute ignored on a function returning ‘int’ [-Wattributes] 341 | av_alloc_size(2, 3) int av_reallocp_array(void ptr, size_t nmemb, size_t size); | ^~~~~~~~~~~~~ CC libavdevice/alsa_dec.o In file included from ./libavutil/common.h:464, from ./libavutil/avutil.h:296, from ./libavutil/log.h:25, from ./libavutil/timer.h:49, from ./libavutil/internal.h:42, from libavdevice/alsa_dec.c:50: ./libavutil/mem.h:341:1: warning: ‘alloc_size’ attribute ignored on a function returning ‘int’ [-Wattributes] 341 | av_alloc_size(2, 3) int av_reallocp_array(void ptr, size_t nmemb, size_t size); | ^~~~~~~~~~~~~ CC libavdevice/alsa_enc.o In file included from ./libavutil/common.h:464, from ./libavutil/avutil.h:296, from ./libavutil/log.h:25, from ./libavutil/timer.h:49, from ./libavutil/internal.h:42, from libavdevice/alsa_enc.c:42: ./libavutil/mem.h:341:1: warning: ‘alloc_size’ attribute ignored on a function returning ‘int’ [-Wattributes] 341 | av_alloc_size(2, 3) int av_reallocp_array(void ptr, size_t nmemb, size_t size); | ^~~~~~~~~~~~~ CC libavdevice/avdevice.o In file included from ./libavutil/common.h:464, from ./libavutil/avutil.h:296, from ./libavutil/avassert.h:31, from libavdevice/avdevice.c:19: ./libavutil/mem.h:341:1: warning: ‘alloc_size’ attribute ignored on a function returning ‘int’ [-Wattributes] 341 | av_alloc_size(2, 3) int av_reallocp_array(void *ptr, size_t nmemb, size_t size); | ^~~~~~~~~~~~~ I had to interrumpt the process because it keeps going on like this.

@Ketchup901: First, you need to remove the old package by running sudo pacman -R ffmpeg-compat-57, run an update (sudo pacman -Syu) and go back to the directory which you cloned this repository (assuming you used git) and run makepkg -fsi. This should rebuild the package properly.

Prevents update of libvpx:

:: installing libvpx (1.8.0-1) breaks dependency 'libvpx.so=5-64' required by ffmpeg-compat-57

@Plailect do a clean build (makepkg -f)
