| CarlFK | mithro - I am about to try to hook the hdmi2usb to dvswitch... if any success, then use it in production in 8 hours | 13:52 |
| mithro | CarlFK, how? | 13:52 |
| CarlFK | with that ffmpeg pipe | 13:52 |
| CarlFK | unless you have any other ideas | 13:53 |
| CarlFK | ill try them too | 13:53 |
| CarlFK | dod you mention gstreamer ? | 13:53 |
| mithro | CarlFK, micolous_ needs to finish writing it first :P | 14:01 |
| mithro | CarlFK, what firmware are you using? | 14:01 |
| mithro | https://github.com/jahanzeb/HDMI2USB_prebuild | 14:02 |
| tpb | Title: jahanzeb/HDMI2USB_prebuild · GitHub (at github.com) | 14:02 |
| CarlFK | um.. good Q | 14:02 |
| CarlFK | the one in the main git repo | 14:02 |
| mithro | that is old | 14:02 |
| mithro | in the middle of re-organising the repositories | 14:02 |
| CarlFK | then get it updated... please | 14:02 |
| mithro | probably be a week or two before it all settles down | 14:03 |
| mithro | be back in 20 minutes - walking home | 14:03 |
| CarlFK | k | 14:03 |
| *** mithro has quit IRC | 14:07 | |
| *** mithro has joined #timvideos | 14:24 | |
| mithro | CarlFK, back | 14:24 |
| mithro | CarlFK, elena is working on a case for the prototype boards | 14:24 |
| CarlFK | oh oh.. please tell me you will use usbB connectors | 14:25 |
| CarlFK | I have had a few of the little usb connectors fail on me.. | 14:25 |
| CarlFK | i think the outer housing of the jack (device side) gets worked open so it doesn't hold the plug in snuggly | 14:26 |
| CarlFK | reminds me of the small firewire connectors, only those things are shipped lose | 14:27 |
| mithro | CarlFK, case | 14:31 |
| CarlFK | case has holes for connectors, right ? | 14:32 |
| mithro | sure, but there is always going to be a microusb connector inside the case | 14:32 |
| CarlFK | why can't it be the larger connector ? | 14:33 |
| mithro | because we are not desoldering the microusb connector from the board | 14:35 |
| mithro | ----> the prototype boards | 14:35 |
| CarlFK | oh... this is a case for the whole atlys board | 14:35 |
| CarlFK | right | 14:35 |
| CarlFK | yeah - never mind that | 14:36 |
| mithro | CarlFK, yes | 14:39 |
| mithro | so you don't destroy it while waiting for the real board | 14:39 |
| CarlFK | yeah - I wonder if I should screw the board into the plastic case the board is shipped in | 14:42 |
| CarlFK | and add some velcro ties to keep the hdmi cables from yanking the connectors around too much | 14:43 |
| mithro | CarlFK, any luck or should I go to bed? | 14:54 |
| CarlFK | oh hell.. got distracted | 14:58 |
| CarlFK | give me 10 min here | 14:58 |
| CarlFK | can you give me the URLs to the 2 files I need? | 14:59 |
| CarlFK | so I can do this: # wget -N https://github.com/jahanzeb/HDMI2USB/raw/master/release/R2/pre-build/hdmi2usb.bit | 15:03 |
| tpb | <http://ln-s.net/-L:l> (at github.com) | 15:03 |
| mithro | They are in the https://github.com/jahanzeb/HDMI2USB_prebuild repository , which only has the files you need now | 15:06 |
| tpb | Title: jahanzeb/HDMI2USB_prebuild · GitHub (at github.com) | 15:06 |
| CarlFK | wget -N https://github.com/jahanzeb/HDMI2USB_prebuild/raw/master/hdmi2usb.bit | 15:08 |
| CarlFK | wget -N https://github.com/jahanzeb/HDMI2USB_prebuild/raw/master/hdmi2usb.hex | 15:08 |
| CarlFK | those, right? | 15:08 |
| tpb | <http://ln-s.net/-U$c> (at github.com) | 15:08 |
| tpb | <http://ln-s.net/-U$d> (at github.com) | 15:08 |
| mithro | yes | 15:11 |
| mithro | but they are likely to change in the near future | 15:11 |
| mithro | so I wouldn't depend on them being stable | 15:12 |
| CarlFK | do you know where djtgcfg came from? | 15:13 |
| CarlFK | I have it in /usr/local/bin/djtgcfg - no idea how it got there | 15:13 |
| mithro | Yes | 15:13 |
| mithro | the Digilent tools | 15:13 |
| CarlFK | file name? | 15:13 |
| CarlFK | I have a bunch of tar/gz files and stuff | 15:14 |
| mithro | https://github.com/timvideos/HDMI2USB/wiki/Digilent-Atlys-Board:-Loading-Firmware | 15:14 |
| tpb | <http://ln-s.net/-H0v> (at github.com) | 15:14 |
| mithro | To use this method you must have the Adept 2.XX.XX Utilities installed and Adept 2.XX.XX Runtime installed. | 15:14 |
| CarlFK | you donfile name? | 15:14 |
| CarlFK | you dont know the file name do you :) | 15:14 |
| *** bananadine has quit IRC | 15:14 | |
| mithro | nope! | 15:15 |
| mithro | that page has links to them | 15:15 |
| CarlFK | I need to run this on another box - my dev laptop's eithernet jack is 1/2 broken, so it falls out | 15:15 |
| CarlFK | I bet it doesn't | 15:16 |
| CarlFK | I have a feeling it was one of the files behind a registration wall | 15:16 |
| mithro | hrm | 15:16 |
| mithro | I just clicked them | 15:17 |
| mithro | and it downloaded fine | 15:17 |
| mithro | diglient.adept.*.tar.gz | 15:17 |
| CarlFK | do you have a url I can wget ? | 15:17 |
| CarlFK | I have digilent.adept.runtime_2.10.2-x86_64.tar.gz digilent.adept.utilities_2.1.1-x86_64.tar.gz | 15:18 |
| mithro | yeah | 15:18 |
| mithro | install them | 15:18 |
| mithro | http://www.digilentinc.com/Data/Products/ADEPT2/digilent.adept.runtime_2.13.1-x86_64.tar.gz | 15:19 |
| tpb | <http://ln-s.net/-U$t> (at www.digilentinc.com) | 15:19 |
| mithro | Come on Carl, not really that hard to click a link or two :P | 15:19 |
| CarlFK | thats how I eneded up with 26 fiiles in my tv dir | 15:19 |
| CarlFK | ffmpeg -f video4linux2 -s vga -r 25 -i /dev/video0 -f s16le -ar 48000 -ac 2 -i /dev/zero -target pal-dv - | dvsource-file /dev/stdin | 15:28 |
| CarlFK | I should do -r 29.89 right ? | 15:28 |
| CarlFK | yeah... (replace 'pal-dv' by 'ntsc-dv' if wanted. Note that -r25 is wrong for ntsc, has to be something like -r30 or some such) | 15:29 |
| mithro | so | 15:30 |
| mithro | the input is only going to be 15fps | 15:30 |
| mithro | I have no idea how ffmpeg will deal with that... | 15:30 |
| mithro | To force the frame rate of the input file (valid for raw formats only) to 1 fps and the frame rate of the output file to 24 fps: | 15:31 |
| mithro | ffmpeg -r 1 -i input.m2v -r 24 output.avi | 15:31 |
| mithro | I wonder if -target pal-dv sets the correct framerate | 15:32 |
| CarlFK | [video4linux2 @ 0x1897300] The V4L2 driver changed the video from 640x480 to 1024x768 | 15:33 |
| CarlFK | [video4linux2 @ 0x1897300] The driver changed the time per frame from 100/2989 to 2/15 | 15:33 |
| CarlFK | and then locked up | 15:33 |
| CarlFK | top shows ffmpeg 90-95% cpu | 15:35 |
| CarlFK | and nothing is hitting dvswitch | 15:35 |
| mithro | CarlFK, so ffmpeg is probably stupid | 15:35 |
| mithro | CarlFK, and doesn't like the fact that the V4L2 driver didn't return data in for format requested | 15:35 |
| CarlFK | it was working with my laptops wecam /dev/video0. switched it to video1, nothing on dvswitch | 15:35 |
| mithro | CarlFK, can you kill ffmpeg and see if you get output with luvcview? | 15:36 |
| mithro | your laptop's webcam probably supports a wide variety of video/frame rates | 15:37 |
| CarlFK | luvcview -d /dev/video1 .. black screen | 15:38 |
| CarlFK | mplayer did give me the test patteren | 15:38 |
| mithro | but it's not anymore? | 15:39 |
| CarlFK | http://paste.ubuntu.com/5877815/ ioctl querycontrol error: Invalid argument Set Saturation up error | 15:39 |
| tpb | Title: Ubuntu Pastebin (at paste.ubuntu.com) | 15:39 |
| CarlFK | correct - mplayer won't play it either | 15:40 |
| CarlFK | v4l2: ioctl set format failed: Device or resource busy | 15:40 |
| mithro | CarlFK, power cycle the device and check that mplayer is giving you the test pattern | 15:42 |
| CarlFK | ill have to reload firmware, right ? | 15:42 |
| mithro | yes | 15:42 |
| mithro | we could program the flash with the firmware | 15:43 |
| mithro | then you wouldn't need to do that | 15:43 |
| mithro | but at the moment I'm not ready to make that call | 15:43 |
| CarlFK | v4l2: unable to open '/dev/video1': No such file or directory | 15:43 |
| CarlFK | I am guessing something locked up the v4l driver | 15:44 |
| CarlFK | carl@dc10:~/tv$ ls /dev/video* | 15:44 |
| CarlFK | /dev/video0 /dev/video1 | 15:44 |
| mithro | your power cycles the device and reflashed? | 15:44 |
| CarlFK | yes.. I think I ran mplayer too soon | 15:45 |
| CarlFK | luvcview gives me the test pattern | 15:45 |
| CarlFK | now mplayer works too | 15:46 |
| CarlFK | ffmpeg ... -s vga I wonder why that is there | 15:48 |
| CarlFK | I has test pattern in dvswitch! | 15:49 |
| CarlFK | aloaded | 15:49 |
| mithro | I think you just want to remove the paramters are the front | 15:49 |
| mithro | try | 15:49 |
| mithro | ffmpeg -f video4linux2 -i /dev/video0 -f s16le -ar 48000 -ac 2 -i /dev/zero -target pal-dv - | dvsource-file /dev/stdin | 15:49 |
| CarlFK | load average: 5.64, | 15:50 |
| CarlFK | could hardly type | 15:50 |
| mithro | can you paste the ffmpeg output somewhere? | 15:51 |
| mithro | scaling 1024x768 raw video to pal-dv should be pretty trivial.... | 15:52 |
| CarlFK | http://paste.ubuntu.com/5877858/ | 15:53 |
| tpb | Title: Ubuntu Pastebin (at paste.ubuntu.com) | 15:53 |
| mithro | what is consuming all your CPU? | 15:56 |
| mithro | ffmpeg? | 15:56 |
| CarlFK | my HD is .. "on" guessing swapping but top doesn't show kswapd or whatever | 15:56 |
| CarlFK | it seems to have settled down now | 15:57 |
| mithro | output from top? | 16:00 |
| CarlFK | where the hell is the "new paste" button? | 16:01 |
| mithro | "new paste" ? | 16:01 |
| CarlFK | http://paste.ubuntu.com/5877878/ | 16:02 |
| tpb | Title: Ubuntu Pastebin (at paste.ubuntu.com) | 16:02 |
| mithro | !? | 16:02 |
| mithro | 1852 carl 20 0 919m 130m 8512 S 52 3.6 608:30.12 compiz | 16:02 |
| CarlFK | im jsut whining. can't figure out how to quicky go from http://paste.ubuntu.com/5877878/ to a new empty | 16:02 |
| tpb | Title: Ubuntu Pastebin (at paste.ubuntu.com) | 16:02 |
| CarlFK | yeah - I always wonder about compiz | 16:02 |
| mithro | where is ffmpeg on that? | 16:02 |
| mithro | why are you even running compiz? | 16:03 |
| CarlFK | becuase ubuntu installed it i guess ;/ | 16:03 |
| mithro | it can be installed | 16:05 |
| mithro | but just disable visual effects in the appearance tab | 16:05 |
| mithro | so | 16:06 |
| mithro | it all good then? | 16:06 |
| CarlFK | I just hooked up a pie hoping to get something moving so I can see how much lag there is | 16:07 |
| CarlFK | in System Settings, Appearance doesn't have "visual effects" - I have seen that option somewhere... | 16:07 |
| CarlFK | i'll worry about that later | 16:08 |
| CarlFK | I have pi output in dvswitch | 16:09 |
| CarlFK | and swapping/maxed cpu.. getting top with ffmpeg now | 16:13 |
| CarlFK | once firefox comes back I'll paste it | 16:15 |
| mithro | check your memory usage | 16:15 |
| CarlFK | with free or ps or? | 16:16 |
| CarlFK | http://paste.ubuntu.com/5877922/ | 16:20 |
| tpb | Title: Ubuntu Pastebin (at paste.ubuntu.com) | 16:20 |
| CarlFK | if you need to get to bed I think I can take it from here | 16:20 |
| mithro | okay | 16:29 |
| mithro | no way ffmpeg should be using 45% of your memory | 16:29 |
| mithro | wow, looks like gstreamer can't produce dv files!? | 16:33 |
| CarlFK | years ago when I tried to use that ffmpeg command to hook a web cam to dvswitch, it got out of sync with reality prety quick - I am guessing it is feeing a buffer faster than it is reading from it | 16:33 |
| mithro | dvswitch is reading pal-dv right? | 16:34 |
| CarlFK | either pal or ntsc | 16:35 |
| CarlFK | it uses what ever the first source uses | 16:36 |
| mithro | add a -t to dvsource command line | 16:36 |
| mithro | what happens if you try to stream a nstc stream to a system which had pal connect first? | 16:36 |
| mithro | ffmpeg -f video4linux2 -i /dev/video0 -f s16le -ar 48000 -ac 2 -i /dev/zero -target pal-dv - | dvsource-file -t /dev/stdin | 16:37 |
| CarlFK | dvswitch throws a ! icon over the thumb.. and I think jsut adds/drops frames to sync it with whatever fps the first source uses | 16:38 |
| CarlFK | dvsource-file: invalid option -- 't' | 16:39 |
| CarlFK | Usage: dvsource-file [-h HOST] [-p PORT] [-l] FILE | 16:39 |
| mithro | your dvsource-file doesn't match trunk | 16:40 |
| mithro | you might give mencoder a go too | 16:40 |
| mithro | mencoder -vop scale=720:576 -oac pcm -ovc libdv | 16:40 |

| CarlFK | see ya | 16:43 |
| mithro | good luck I guess | 16:44 |

| CarlFK | "Rachel Dean" <xxxxxxxxxxxxx@xxxxxxxxx>, sent | 18:43 |
| parx | uhh, he didn't quite supply the items on your list | 18:46 |
| CarlFK | then he says | 18:48 |

| parx | ... | 18:50 |
| CarlFK | he just sent out an announcement mail.. it's better.... | 18:50 |
| parx | I got that | 18:50 |
| parx | Maybe if you add numbers to your vertical list it will help people to realize "Oh there are three items on this list. I have to provide three things." | 18:52 |
| CarlFK | maybe... | 18:52 |
| CarlFK | I am skeptical :) | 18:53 |

| CarlFK | iiie: did you see/hear/read I got the board to talk to dvswitch | 18:58 |
| CarlFK | yeah - but no recording in the 5th | 18:58 |
| CarlFK | so just for 4! | 18:58 |
| CarlFK | and AV is kinda provided ... well... equipment and some guy in another office | 18:59 |
| iiie | no, awesome transitional | 18:59 |
| iiie | hm, so they give us room audio? | 18:59 |
| CarlFK | yeah | 18:59 |
| CarlFK | I am not sure it makes my life any easier | 19:00 |
| iiie | Means that the volunteers have to deal with a little less | 19:00 |
| iiie | but yeah if it doesn't work there isn't anything to do... | 19:00 |
| CarlFK | I seem to remember "yeah, we have heard that hum before. can't hear it over the PA, so no one has bothered to fix it" | 19:01 |
| iiie | ... | 19:02 |
| * iiie wonders if gstream will let us post process audio with low, high, band and notch filters? | 19:02 | |
| CarlFK | so I end up running the mics into my mixer, then a cable back to their PA | 19:04 |
| iiie | he he he | 19:04 |
