| Oksanaa | What's the way to capture a screenshot when gstreamer is involved? Usual ways do not cut it, because it's gstreamer. I have an awareness of gst-launch, but no idea about finding appropriate src. | 07:54 |
|---|---|---|
| Oksanaa | Aka, taking screenshot of camera's frozen view-finder since the camera didn't manage to save the photo to file. And asking the person to sit for a photo, a second time is... awkward. | 07:55 |
| Oksanaa | Like, I got a nice picture of viewfinder's corners with ximagesrc or something, but on purely black background. There viewfinder's rendering of photograph remains an elusive src. | 08:02 |
| Oksanaa | Is photograph-ing the display with another camera really the only solution? I have not much battery left. | 08:05 |
| Maxdamantus | I just take screenshots using `scrot` inside my debian chroot. | 08:08 |
| Maxdamantus | You should also be able to use scrot/import over a X11 over ssh. | 08:09 |
| Maxdamantus | so should be able to `ssh -X` from maemo to another machine and run scrot/import there. | 08:10 |
| Maxdamantus | http://maxdamantus.eu.org/maemosshscrot.png | 08:12 |
| Oksanaa | Ssh -X, done. Import, exists. What to do with it? | 08:13 |
| Maxdamantus | I think you just run `import foo.png` | 08:13 |
| Maxdamantus | and it will save the image as `foo.png` in the current directory (on the host you've sshed to) | 08:14 |
| Maxdamantus | Looking at that picture of mine .. why do I put up with this horrible font rendering? | 08:14 |
| * Maxdamantus doesn't usually see things that terrible on his main display. | 08:14 | |
| Maxdamantus | Oh, in your case you'd probably do something like `sleep 2 && import foo.png`, then switch to the camera-ui window before the sleep exits. | 08:16 |
| Oksanaa | Yes :-) Which app to use to preview png? | 08:16 |
| Oksanaa | Heard about sleep from https://wiki.maemo.org/Phone_control#Take_a_picture_with_front_camera | 08:17 |
| Maxdamantus | I use scrot (on both maemo and other systems) | 08:17 |
| Maxdamantus | er, sxiv* | 08:17 |
| Maxdamantus | but the image should just end up on the host you ran `import` on, not on maemo. | 08:18 |
| Oksanaa | Sxiv... Not installed. What's the one on KDE Debian? Gsomething | 08:18 |
| Maxdamantus | so you'd just use whatever you normally use to look at PNGs. | 08:18 |
| Maxdamantus | Presumably if you have a web browser installed you could just use that. | 08:18 |
| Oksanaa | Don't want to mess up firefox session of tabs. | 08:19 |
| Oksanaa | Let's see how konqueror works out for previewing a png. | 08:20 |
| Maxdamantus | you might also try `showimage`, if that's installed. | 08:20 |
| Maxdamantus | I think that comes with sdl-image, but iirc it's not there on Debian. | 08:21 |
| Oksanaa | Okay, minimalistic capture done. No idea how to get rid of viewfinder overlays. And probably 800x480 resolution. .. | 08:21 |
| *** sunshavi has quit IRC | 08:22 | |
| Oksanaa | Would still appreciate gst-launch capture from frozen view-finder. But not much battery left. | 08:22 |
| Maxdamantus | I suspect the 800×480 problem will only be solved by taking a memory dump and trying to extract the image from that. | 08:22 |
| Oksanaa | Probably. No idea if a gstreamer sink, src or bin offers high resolution picture. It may well be that view-finder remembers only screen-res. | 08:23 |
| Maxdamantus | You should probably at least make sure to get that memory dump before it runs out of battery. | 08:24 |
| Maxdamantus | something like `gcore foo.bin` once you've attached to camera-ui using `gdb --pid 1234` | 08:25 |
| Maxdamantus | but it might be tricky to get the image out of it, if it's possible at all. | 08:25 |

| Oksanaa | Yo, good idea for next time. This time, I am just glad that screenshot was made. Gdb should be run on N900, and gcore can be run on a different computer? | 09:54 |
| bencoh | you can use gdbserver on n900 and gdb on a remote computer | 09:55 |
| Oksanaa | Thank you. Should figure out what's the problem with camera that it freezes at times. Sometimes, two cameras are visible in window-switcher at the same time. | 09:56 |
| *** cyteen has joined #maemo | 10:01 | |
| *** Pali has joined #maemo | 10:13 | |
| Maxdamantus | gcore is a command in gdb to save a core dump. | 10:36 |
| Maxdamantus | The simple thing to do is to just run gdb locally and in that local session run gcore so you can inspect it later. | 10:38 |

| Enrico_Menotti | Hi. I thought I could start learning some things about Hildon. After a bit of googling, I decided to begin with the GTK+ libraries. So I'm trying to compile them on Devuan. I'm reading here: https://developer.gnome.org/gtk3/stable/gtk-building.html. I'm encountering many issues, solved a bunch of them, but now I'm stuck at a certain point. Let me report what I'm doing so far. | 21:53 |
| Sicelo009N | you'll have to read up on what Android_808 and freemangordon are doing ... there's a thread on tmo | 21:55 |
| Enrico_Menotti | Yes, I know they're doing something. Since I don't know the basics yet, I thought I could try first on the laptop, without thinking about the N900 for now. | 21:56 |
| Enrico_Menotti | (Although I don't know which thread exactly you refer to.) | 21:56 |
| Sicelo009N | you'll probably want to start with gtk2 if your aim is Hildon | 21:57 |
| Enrico_Menotti | Maybe http://talk.maemo.org/showthread.php?t=96800? | 21:58 |
| Sicelo009N | yes | 21:59 |
| Sicelo009N | or maybe no need for GTK2 :-) | 21:59 |
| Enrico_Menotti | Ok. So I admit I'm still orienting in this topic. What is the difference between gtk+ and gtk2? | 22:00 |
| Sicelo009N | none .. gtk2 and gtk3 are just different versions of gtk(+) | 22:02 |
| Enrico_Menotti | Ok. I started by cloning this: https://git.gnome.org/browse/gtk+. On the page about gtk building that I linked above, they say to run ./configure. So the first problem is that this script does not exist. Instead, I found autogen.sh, which seems to create configure and execute it. Then a make successfully starts the build. | 22:05 |
| *** xy2_ has joined #maemo | 22:06 | |
| Enrico_Menotti | Now the newest versions of gtk+ require libraries which seem not to be available on Devuan Jessie, at least not in the required version. So I checked out a previous branch, gtk-3-14. This allows the build process to go fairly ahead. | 22:08 |
| Sicelo009N | i guess that's where you need fmg/android_808 | 22:09 |
| Enrico_Menotti | What do you propose to do? Asking here is not the right way? Should I post on that thread? (Yes, I didn't read all the thread yet, but my present knowledge is so small that I couldn't understand many things.) | 22:10 |
| Sicelo009N | i'm sure they can help you here when they are online | 22:11 |
| Enrico_Menotti | Ok, so I'd report some more details, ok? | 22:12 |
| Enrico_Menotti | (I see freemangordon online - maybe he will read later.) | 22:13 |
| Enrico_Menotti | I got the following error from the linker: | 22:14 |
| Enrico_Menotti | /bin/sed: can't read /usr/local/lib/libgobject-2.0.la: No such file or directory | 22:14 |
| Enrico_Menotti | This seems to be triggered by the linking process of libgdk-3.la. | 22:15 |
| Enrico_Menotti | So after some googling I found this: https://bugzilla.gnome.org/show_bug.cgi?id=679409 and this: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=732668. | 22:15 |
| povbot | Bug 679409: was not found. | 22:15 |
| Enrico_Menotti | (Also https://mail.gnome.org/archives/commits-list/2012-July/msg02309.html.) | 22:17 |
| Enrico_Menotti | If I got it right, gtk+ has a behaviour (linking against .la files) which seems to be deprecated (based on the Debian bug report above.) | 22:20 |
| Enrico_Menotti | That's it. Any suggestion is well accepted. :) | 22:22 |
