Phoronix IRC Log: 2009-10-19
Kano: hi michaellarabel
Kano: hi redeeman
Kano: michaellarabel: are you interested in hybrid iso images
Kano: i worte a script that can convert any isolinux image to hybrid
Kano: just gfxboot will not work
Kano: redeeman: for usb stick + cd
Kano: would work for pts too
Kano: simple test it to use qemu -hda image.iso
Kano: instead of -cdrom image.iso
Kano: to try the menu
Kano: if you prefer a syslinux version, similar to the ubuntu gui tool, just cli
Kano: that script even supports win vista + 7
Kano: as i found it really stupid to boot win to create such a stick
Kano: the diskpart way works of course, but it not that easy for beginners. ok, ultra iso has got a gui for that too, but as syslinux can simply chainload it, there is a much easier way
Kano: i even tested a variant of my update-isolinux script on 7, it booted the installed but did not found the files. well 7 has got problems to see files from iso9660/udf formated usb sticks anyway
Kano: so hybrid iso would be possible if ms would manage to show files on those usb sticks
bkero: 7 can't even mount an iso :/
Kano: well you can BURN it now, but i guess only full speed which results usally in bad quality
bkero: Ooo fancy
Kano: i did never use that
redeeman: i always burn at full speed
redeeman: works fine
Kano: i only use 8x speed
Kano: also old dvds tend to get unreadable over the time. i am testing md5sum on those which i want to keep. will make a backup if possible if only readable in drives with better error correction
Kano: you get higher errors rates the faster you burn usually
superdump: does anyone here have any constructive comments on laptop choice
superdump: if the lenovo x200s had an nvidia gpu, it would be perfect for me i think
superdump: but it doesn't
superdump: and the t400 has a radeon hd 3470
superdump: i'm wondering how well that will work in linux
Ivanovic: you can at least use the open source driver which is great for 2d stuff
Ivanovic: though i don't know how will the energy saving stuff works
superdump: i don't _really_ need an awesome gpu but i'm a little concerned if i need to do some GL development while i'm away from home that i wouldn't have anything to test on
Ivanovic: why don't you get one with intel gpu since those are well supported and even have 3d working (though not fast, but working)
Ivanovic: depending on the distribution you use fglrx might "just work" for you
Ivanovic: that is on my desktop system i got no problem with fglrx when installing it via portage (gentoo amd64)
Ivanovic: with fglrx you should have working >= opengl 2.0
Ivanovic: anyway, i should head off to bed now, n8
superdump: i'd probably use ubuntu/xubuntu
Ivanovic: in those regards you would be quite lucky when using an ati card since this is even some "supported distribution"
Ivanovic: so it *should* somehow work
superdump: michaellarabel: i saw some reviews of the hd3470 on phoronix a while ago i think - do you have any idea of the state now?
michaellarabel: superdump: Hey, with fglrx or open-source stack?
superdump: i don't mind
superdump: whatever works best
superdump: the point is to have something that has reasonable GL performance in case i need to do any dev work with it
superdump: looks at michaellarabel
michaellarabel: superdump: HD 3470 should work out fine with Catalyst. It should work fine under open-source too by Ubuntu 10.04 unless you're using the edgers repos now.
superdump: how is the open source stack coming along with respect to 3D?
superdump: in terms of feature-completeness and performance
Ivanovic: superdump: just today i tried world of goo using my hd3850, git libdrm, git mesa and kernel 2.6.32-rc5
Ivanovic: worked nicely
Ivanovic: though starting jack keane resulted in a hardfreeze
michaellarabel: feature-completeness is nearing R500 comparability. Performance is slow like all in comparison to Catalyst, except for 2D
superdump: and are there any rumours about ati/amd dropping support for any more gpus in the near future?
superdump: actually, how is that handled in distros for gpus for which support was dropped?
superdump: are they detected and old catalysts installed instead?
Ivanovic: you just use the open source drivers
Ivanovic: since to be able to use catalyst for those cards you have to rely on some older xorg-server, too
superdump: ah, of course
michaellarabel: superdump: R600 hardware still should be supported for at least another year or more I would say
superdump: by which time the state of the open source stuff should be better i guess
superdump: i thought lots of laptops were shipping with 9400Ms and the GTXXXM chips but it seems not
superdump: acer do some
superdump: but acer's website is horrible to navigate
LordHavoc: michaellarabel: http://ghdigital.com/~havoc/dppics/310.html - screenshot of darkplaces engine svn running e1m1 (Quake1), same engine behind Nexuiz, I redid the e1m1 lights file today :)
LordHavoc: michaellarabel: amazing how over a weekend me and eihrul whipped up shadowmapping that looks great and runs so much faster than xreal
LordHavoc: michaellarabel: a future nexuiz version will use shadowmapping by default because it's actually faster in benchmarks than the stencil
michaellarabel: LordHavoc: Nice, any other info?
LordHavoc: not much, been crunching on other features
superdump: hmm, i think the dell studio line up looks nice spec-wise for the money
michaellarabel: superdump: Anything new in FFmpeg world?
superdump: hmm, well, i should be getting funding for a merge of ffmpeg-mt into trunk
superdump: i published the he aac v1 (SBR) code i've written so far (which is the majority of it) but it needs finishing off and cleaning up
superdump: errrm, not too sure what else has been going on to be honest as i've been quite busy with other things (travelling, sorting out a new job)
superdump: at least, nothing major immediately springs to mind
superdump: work is still ongoing on libavfilter (filter library)
superdump: more arm optimisations
superdump: oh, proper channel layout support for aac and vorbis now
superdump: maybe head over to #ffmpeg-devel and ask as i haven't been as attentive recently
michaellarabel: superdump: Do you know anything about Blu-ray and ffmpeg yet?
superdump: there was a commit to allow demuxing of combined true hd/ac-3 tracks as two separate streams
superdump: some work on subtitle support
superdump: and lpcm
superdump: i don't think i've ever personally tried to decode any blu ray content using anything though
superdump: no one said they wanted the blu ray drive last time
superdump: but there's a steady stream of interest and fixes
superdump: my guess is that it works to some extent right now (the streams, not menus and whatever)
