samsagaz_WTH)!) 10USD cameras!?!? wow01:43
samsagaz_canon xc20 and xc30 are not available in argentina02:08
CarlFKsamsagaz_: $10 used.02:20
samsagaz_ah ok impossible here then :/02:21
CarlFKI expected complete garbage, mainly wanted it for testing in my living room.  turns out it is good enough for doing real work02:21
samsagaz_i see02:22
samsagaz_which are the specs that i need to search for the camera?02:22
samsagaz_some recommendations?02:22
CarlFKassuming you want to engage our little community here and share our stuff...02:23
CarlFK720p hdmi - that is what we are currently using.02:24
samsagaz_ok02:24
CarlFKI 1/2 want to say we should have this documented, but really "it depends"02:25
tumbleweedI find SDI more reliable than HDMI, but you don't get it on cheap cameras02:25
CarlFKyeah, I am digging the sdi too. but I wouldn't even bother putting it on this list02:26
tumbleweedyeah02:27
tumbleweedsamsagaz_: you looked at hiring? the audio equipment can easily cost more to hire than cameras02:27
samsagaz_i just want to prepare a document to show to the pyar (python argentina) board with the alternatives02:28
samsagaz_wow Panasonic Ag-ux180 5715USD in argentina02:29
samsagaz_lol02:29
samsagaz_i see what we get so crap quality we was using 250USD cameras :)02:33
tumbleweedI'd say the quality of the cameras is less important than audio and screen capture02:38
tumbleweedI'm sure someone could make pretty decent conference video with a high end webcam and good lighting, given good audio and video capture02:39
CarlFK[m]+1'02:41
CarlFK[m]also it may be way easier to setup than an expensive/fragile camera, larger tripod, power, audio and video cables attached to it02:43
CarlFK[m]you will have to deal with audio some other way, but I did it with usb dongles for a few year02:43
samsagaz_sure the problem that we have is the audio in the last events...03:11
samsagaz_really bad quality03:11
samsagaz_how you solve the audio problem? i see that HDMI2USB are just used for video03:13
samsagaz_how recommend to record the audio?03:13
tumbleweedthe easiest is to get audio from the mixing desk into the camera03:15
tumbleweedbut that needs a mid-to-high end camera with XLR inputs03:15
tumbleweedand a mixing desk with sub-mixes (ideally)03:16
tumbleweedthen you capture from the camera with a blackmagic card (or something), and your audio will be in sync with the video03:17
tumbleweedanother way is to capture the audio directly with a USB audio interface. Then you need to tweak delay a bit, to get things into sync03:17
samsagaz_yes, the sync will be a pain03:17
tumbleweedit's actually not that bad03:17
tumbleweedonce you've figured out what delay to use03:17
tumbleweedvoctomix makes both of these approaches pretty easy03:18
samsagaz_will search about victomix thanks guys.03:19
tumbleweedthat's the live video mixing system we all use03:20
samsagaz_nice03:21

tpbTitle: GitHub - CarlFK/voctomix-outcasts (at github.com)03:48
CarlFK[m]good audio starts with having good audio for the attendees03:49
CarlFK[m]so so audio is ok for attendees, but the same so so audio on a recording bothers people03:50
samsagaz_ thanks guys for all your support03:54
CarlFK[m]samsagaz_ do you run linux?03:58
samsagaz_yes arch in my laptop03:58
samsagaz_but i like fedora too03:59
samsagaz_the gui dont work on arch04:01

CarlFK[m]do you have a box you can install debian or ubunto desktop on?04:39
CarlFK[m]a low end i3 cpu should be fine04:39

CarlFK[m]then you can get it working on any os04:40

shornehow are you debugging with openocd and hdmi2usb-litex-firmware then?13:35
*** sb0 has joined #timvideos14:07
_florent_shorne:  if you want to try, here is the patch adapted to litex (for the gateware part), this is untested and you will have to fix the verilog paths at the end of core.py15:12
