mithroaps-sids: did you get anywhere with dvswitch?04:49
*** tija has quit IRC04:56
aps-sidsmithro: morning. I boot up in CarlFK's Vagrant Box and dont know what to do next.04:57
CarlFKdo you see the dvswitch gui?04:57
CarlFK  looks about like that04:58
tpbTitle: DVswitch (at
aps-sidsCarlFK: yes and btw I have to enter password vagrant, its not logging in automatically04:59
CarlFKhmm.. it's been a while.. but that surprises me04:59
CarlFKlets hope that is the only thing that is odd05:00
CarlFKin the lower row of thumbs, is there a bouncing ball?05:00
aps-sidsCarlFK: in dvsmon I see errors, some packages missing. I'm manually installing them now05:01
CarlFKswell.  this was spozed to be a nice static thing05:02
CarlFKill run it over here and see what happens05:03
*** tija has joined #timvideos05:07
tpbTitle: large meeting (at
mithroaps-sids: I would have just suggested doing an "apt-get install dvswitch" and then trying the commands on the above URL05:09
aps-sidsWhat can I say? Carl loves vagrant ;)05:10

shenkiwho wants to review some vhdl and verilog?05:14
aps-sidsshenki: I'm just curious to see how that code looks ;)05:18
tpbTitle: Commits · shenki/HDMI2USB · GitHub (at
shenkiaps-sids: the top 4 commits05:22
shenkimithro: do you want to take a look? if they're good, we'll merge into master on the main repo05:22
aps-sidsNot sure if Verilog code or Very Long code :P05:24
mithroshenki: Do you know if there is a way to make the debug signals get automagically wired together? Otherwise I think it seems pretty good?05:26
shenkimithro: what do you mena?05:27
mithroIE, it would be nice is a "module"/"subsystem" could just instantiate a bunch of debug counters and then they would get automagically published via the debug system up the UART05:28
shenkiright. you'd have to create some kind of preprocessor system do that05:30
shenkihave a python script that scrapes all the _debug signals and collects them05:30
shenkior similar05:30
mithroshenki: there is a horrible thing called "verilogperl" which I think we probably want to stay away from :P05:31
shenkiyep. good call :)05:32
shenkia guy i worked with at my last job who did fpga contracting for us had a cool system of makefiles and python that he would use to generate filters05:33
shenkiso you could design the filters in python, and then spit out the vhdl with all the coeffs and stuff05:33
shenkias well as your testbenches05:33
mithroshenki: I think FeltonChris has something like what with MyHDL05:41
shenkikinda. this is more about describing the filters at a high level, and then generating all of the boilerplate and vhdl afterwards05:43
shenkiwhereas myhdl is more about describing the vhdl that you want generated05:43
shenkia subtle difference ;)05:43
aps-sidsCarlFK: there is some dpkg problem, I even tried destroying and re-creating the box05:51
mithroaps-sids: want to give my approach a try?06:00
aps-sidsmithro: yeah, doing that already06:00
aps-sidsmithro: this reads input from firewire source, I don't have that06:12
*** Niharika1 has joined #timvideos06:27

mithroaps-sids: there is a dvsource-file I think?06:32
aps-sidsmithro: I'm using CarlFK 's dvsmon now, and trying to get over the errors,  "ERROR: bind: Cannot assign requested address"06:33
aps-sidslooking where address is given06:33

aps-sidsmithro: okay, got it working. Now installing ported dvswitch plugin06:37
shenkitija: hey06:37
aps-sidsmithro: Carl's dvsmon and test scripts run with 0.10, I'd have to edit those06:49
shenkitija: are you happy for the version of your debug framework that i have on my branch be merged into the main repo?06:50
tpbTitle: Commits · shenki/HDMI2USB · GitHub (at
shenkiplease take a look06:50
aps-sidsmithro: I'm getting this error when trying to install ported dvswitch plugin. I don't have much experience with dpkg07:01
tpbTitle: Pastebin: 070ERMId | IRCCloud (at
aps-sidsmithro: I think something is wrong in configure or something07:02
*** Niharika1 has quit IRC07:02
shenkithe last answer has clues for the real fix07:06
mithroaps-sids: it looks like you need to fix a couple of references in debian/rules too07:24
mithroaps-sids: it's still referencing gstreamer0.1007:24
aps-sidsmithro: but make install should work right? its installing in correct place but element still not available in gst-inspect-1007:27
mithroaps-sids: gst-inspect-0.10 or gst-inspect-1.0 ?07:28
aps-sidsIts ported right, so 1.007:28
mithroaps-sids: is the file in the right location? Maybe it accidently installed to the 0.10 location?07:31
aps-sidsmithro: I checked that its in usr/lib/gstreamer-1.007:31
mithrogreat! Now I have no idea :P07:32
mithroaps-sids: do an strace of gst-inpect maybe and check what it is doing?07:33
aps-sidsmithro: I tried changing references in debian/control07:38
aps-sidsand now I get07:38
aps-sidsdpkg-source: error: source package has two conflicting values - gstreamer1.0-dvswitch and gstreamer0.10-dvswitch07:38
mithroaps-sids: "grep -R gstreamer0.10 debian/"07:39
aps-sidsgrep doesn't give me any occurence of 0.10 except one in changelog07:39
aps-sidsdoes that matter?07:39
mithroaps-sids: actually - It think it might07:40
aps-sidsit does07:40
mithroaps-sids: one way to make sure you update the ChangeLog is to make it used :P07:40
aps-sidsmithro: okay, this now07:41
aps-sidsdpkg-shlibdeps: error: no dependency information found for /usr/lib/ (used by debian/gstreamer1.0-dvswitch/usr/lib/gstreamer-1.0/

mithroAnyone want to review my pull request?07:41
shenkimithro: yep07:42
mithroand fix all my inevitable speling mistakes07:42
shenkigithub's silly UI doesn't let you review commit messages07:42
mithroshenki: yeah - I really wish they'd give their review interface a lot of love07:43
shenkimithro: done07:51
shenkimithro: looks good, all my comments are minor things07:51
mithroshenki: I can't figure out how to reply to your commit message comment07:56
shenkimithro: you have to enforce the first line thing. the git tools rely on it08:00
shenkisee how the commit message in the review wraps in the github web UI?08:00
shenkithat's only hte beginning of it08:00
* shenki steps down off his soap box08:03
mithroshenki: The only place I've found an issue is on github when sending a pull request08:07
aps-sidsmithro: doing "gst-inspect-1.0 /usr/lib/gstreamer-1.0/" shows me plugin info08:17

shenkimithro: when you send patches to mailing lists it gets awkward. it also breaks git log --oneline, as the messages don't fit on the screen, same with gitk08:59
mithroI have more than 80 character terminals. Gitk and git log both work fine.09:06

aps-sidsslomo: "gst-inspect-1.0 /usr/lib/gstreamer-1.0/" shows me plugin info but "gst-inspect-1.0 dvswitch" says No such element or plugin 'dvswitch' :(09:33
aps-sidscan you help with that?09:33
slomoaps-sids: check the debug logs what the problem is09:34
aps-sidsslomo: for some reason, it s looking for directory '/usr/lib/frei0r-1'09:37

aps-sidsslomo: do we have to update the registry cache or something? This plugin is installed using make install09:45
*** Niharika has quit IRC09:56
slomoaps-sids: it's doing that automatically10:00
slomoaps-sids: is gst-inspect-1.0 -b showing it as blacklisted?10:00
aps-sidsslomo: no10:00
slomoaps-sids: are other plugins in /usr/lib/gstreamer-1.0 and are they found?10:00
aps-sidsslomo: yes, there are and they are found10:01
aps-sidsslomo: not sure if they are found form their copy from some other place10:02
slomocheck for one of them10:04
slomogst-inspect shows the path at the top10:04
aps-sidsslomo: sorry, internet got disconnected. I think this is the problem. Every plugin is detected from /usr/lib/x86_64-linux-gnu/gstreamer-1.0/10:43
aps-sidshow do I make sure gstreamer looks in /usr/lib/gstreamer-1.0. symlink or anything?10:44
slomoaps-sids: for example, or set GST_PLUGIN_PATH to the other one or let dvswitch install the plugin in the right place10:48

aps-sidsmithro: Okay everything is installed. I run "dvswitch --host=localhost --port=2000" in Terminal-1 and I do "gst-launch-1.0 -v videotestsrc is-live=true ! videoconvert ! avenc_dvvideo ! avmux_dv ! dvswitchsink host=localhost port=2000" in Terminal-212:07
aps-sidsAnd some more cmds like that and I get this  --
aps-sidsSo, I guess plugin is ported?12:08

aps-sidsCarlFK: dvsource-v4l2-other needs to be ported as well, for your box and dvsmon to work properly19:30
