| @tonysss:matrix.org | Hi | 11:05:49 |
| @tonysss:matrix.org | I'm having video playback issues in Firefox | 11:06:07 |
| @tonysss:matrix.org | Such as slowdown, frame skipping and out of sync | 11:06:19 |
| @tonysss:matrix.org | Even outside of YouTube | 11:06:25 |
| @tonysss:matrix.org | I tried installing ffmpeg-libs and free packages while uninstalling openh264 but didn't fix yet | 11:06:56 |
 K900 | Uhhh what ffmpeg-libs | 11:07:07 |
| K900 | This is a NixOS room | 11:07:09 |
| K900 | We don't have ffmpeg-libs | 11:07:15 |
| @tonysss:matrix.org | Yeah I have Nobara | 11:07:27 |
| @tonysss:matrix.org | Sorry perhaps | 11:07:30 |
| K900 | Yeah wrong room then | 11:07:36 |
| K900 | This is Nix as in NixOS | 11:07:39 |
| K900 | Not Nix as in *nix | 11:07:42 |
| @tonysss:matrix.org left the room. | 11:07:45 |
| K900 | Might want to ask the Nobara folks | 11:07:50 |
| K900 | Aaaaand they're gone | 11:08:02 |
| nyanbinary 🏳️⚧️ | Should JSGC_DISABLE_POISONING=1 be enabled in the wrapper maybe for perf (I mean this only matters for nightly really tbf) | 19:59:02 |
| nyanbinary 🏳️⚧️ | Also did not know Firefox had a --extended-corpus option for PGO | 19:59:22 |
| nyanbinary 🏳️⚧️ | --set-default should be fine since users can override it anyways :p | 22:38:09 |
| nyanbinary 🏳️⚧️ | o nvm Mozilla just never updated their documentation saying this is off by default now for optimizied Nightly builds lol | 23:04:12 |

| nyanbinary 🏳️⚧️ | hexa By the way is there a reason buildMozillaMach doesn't pass --enable-rust-simd like Mozilla does for their official builds of Firefox? | 02:16:41 |
 hexa | me sleep | 02:17:06 |
| hexa | and check back next week | 02:17:11 |
| nyanbinary 🏳️⚧️ | alright | 02:18:03 |
| nyanbinary 🏳️⚧️ | So you don't go out searching this is where Mozilla defines it:
https://github.com/mozilla-firefox/firefox/blob/main/build/mozconfig.rust
Then mozconfig.rust gets called by mozconfig.common here:
https://github.com/mozilla-firefox/firefox/blob/main/build/mozconfig.common | 02:18:41 |
| nyanbinary 🏳️⚧️ | https://github.com/NixOS/nixpkgs/blob/master/pkgs/build-support/build-mozilla-mach/default.nix Nixpkgs buildMozillaMach doesn't pass --enable-rust-simd here... | 02:19:13 |
