@skainswo:matrix.orgSamuel Ainsworthyeah, that's fair00:51:08
@skainswo:matrix.orgSamuel Ainsworthwould be nice to get all packages aligned on how to do this in a consistent manner00:51:30
@tpw_rules:matrix.orgtpw_rulesyeah i've used that before, but the fact that it GCs old stuff spooks me a little. like i said i don't update much and not just because of build times, so being forced to upgrade or have to suffer the compile anyway in the future i don't like00:51:47
@skainswo:matrix.orgSamuel AinsworthI haven't encountered missing things due to GC myself, but I can understand the concern00:52:23
@tpw_rules:matrix.orgtpw_rulesisn't that the deal with cachix? it will only keep around the latest builds? i figured with how hongry these derivations are that time would come quickly00:52:46
@tpw_rules:matrix.orgtpw_rulesbut if it's been going for many months now and it hasn't had to GC anything i will reconsider my stance00:53:19
@skainswo:matrix.orgSamuel Ainsworth Domen Kožar has graciously offered the group some nice headroom. o/w ur right we would burn through the cache like every day 00:53:52
@skainswo:matrix.orgSamuel Ainsworthdef show cachix some love if you can!00:54:32
@tpw_rules:matrix.orgtpw_rulesi've said it before but it's still true, thanks very much for leading this. i know the road is bumpy but the value is immense00:55:00
@skainswo:matrix.orgSamuel Ainsworth Thank you so much tpw_rules ! I really appreciate that. It can be grueling at times, so I'm really happy to hear your words of encouragement 00:56:05
@skainswo:matrix.orgSamuel Ainsworthglad that our work is valuable to you as well!00:56:21
@hexa:lossy.networkhexa (UTC+1)sank a few hours into setting up stable-diffusion02:20:37
@hexa:lossy.networkhexa (UTC+1)no dice with rocm on my 5700 XT (NAVI 10)02:20:48
@hexa:lossy.networkhexa (UTC+1)I hate gpus02:20:56
@tpw_rules:matrix.orgtpw_rulesimo it's more software's fault03:00:01
@tpw_rules:matrix.orgtpw_rulesthe gpu still isn't doing anything harder than lots of matrix mults03:00:18
@me:linj.techlinj joined the room.03:58:08
@me:linj.techlinj nvcodec is one of gstreamer's bad plugins and can use nvidia gpu to decode videos. currently I need to do this LD_LIBRARY_PATH=/run/opengl-driver/lib clapper a.mkv to use nvcodec (clapper is a video player based on gstreamer). What is the proper fix for this? addOpenGLRunpath or something else? 04:02:19
@skainswo:matrix.orgSamuel AinsworthYeah that sounds like an addOpenGLRunpath issue04:03:43
@skainswo:matrix.orgSamuel AinsworthIf clapper is packaged in nixpkgs I'd open an issue asking the maintainers to add it04:04:53

should addOpenGLRunpath be added to a leaf app or gst_all_1.gst-plugins-bad?
04:05:45
@skainswo:matrix.orgSamuel AinsworthHmm that depends on how gstreamer plugins work. I'm not familiar with them specifically04:06:34
@skainswo:matrix.orgSamuel AinsworthBut I would suggest adding it to the plugin if at all possible04:06:47
@me:linj.techlinjthanks, I'll ask some gnome guys04:07:15
@skainswo:matrix.orgSamuel AinsworthThere's also an auto patch hook to do it for you! That makes it pretty easy04:08:34

could you provide a link?
04:09:22
@skainswo:matrix.orgSamuel AinsworthNot on my computer rn but I can try to find it later04:09:42
@skainswo:matrix.orgSamuel AinsworthI think it's called something like autoaddopenglrunpathhook04:10:07
@skainswo:matrix.orgSamuel AinsworthOr something like that04:10:11

fair, I hate the rocm support situation and the nvidia driver situation
