| aps-sids | CarlFK: that was not related to dvswitch, just found it interesting :) | 04:38 |
| CarlFK | aps-sids: I have no context.. so... let me know if you need anything ;) | 04:42 |
| aps-sids | sure. I'm suddenly working on C after months of Python :P | 04:43 |

| shenki | aps-sids: can you feel your beard growing already? | 04:44 |
| aps-sids | shenki: I'm a Sikh (religion). We don't trim hair ;) | 04:44 |
| aps-sids | So, I already have a full grown beard | 04:45 |
| shenki | aps-sids: sure, but perhaps it will get longer? :) I was just being silly | 04:45 |

| shenki | :D | 04:45 |
| shenki | aps-sids: what is the c you're hacking on? | 04:46 |
| aps-sids | shenki: porting gst-plugin-dvswitch to 1.0 | 04:46 |
| shenki | cool. have the apis changed much? | 04:47 |
| aps-sids | shenki: Don't know if we can call it "much", but they are quite different | 04:49 |
| shenki | okay | 04:49 |

| mithro | aps-sids: shenki is a C person | 07:39 |
| mithro | aps-sids: I also know a bit of C | 07:39 |
| aps-sids | mithro: I have a doubt here. See this variable "parent_class" here -- https://github.com/aps-sids/gst-plugins-dvswitch/blob/master/src/gstdvswitchsrc.c#L258 | 07:40 |
| tpb | Title: gst-plugins-dvswitch/src/gstdvswitchsrc.c at master · aps-sids/gst-plugins-dvswitch · GitHub (at github.com) | 07:40 |
| aps-sids | I believe its coming from the header file | 07:40 |
| aps-sids | But when I have ported some part of this file, I get this error: 'parent_class' undeclared | 07:41 |
| mithro | does it come from https://github.com/aps-sids/gst-plugins-dvswitch/blob/master/src/gstdvswitchsrc.h#L146 ? | 07:41 |
| tpb | Title: gst-plugins-dvswitch/src/gstdvswitchsrc.h at master · aps-sids/gst-plugins-dvswitch · GitHub (at github.com) | 07:41 |
| aps-sids | mithro: does that mean the class is not initialized properly? | 07:42 |
| aps-sids | s/initialized/instantiated | 07:42 |
| aps-sids | mithro: yes, I think so | 07:42 |
| aps-sids | its coming from gstdvswitchsrc.h | 07:43 |
| mithro | I don't quite know what G_OBJECT_CLASS does | 07:43 |
| mithro | #define G_OBJECT_CLASS(class) (G_TYPE_CHECK_CLASS_CAST ((class), G_TYPE_OBJECT, GObjectClass)) | 07:44 |

| aps-sids | mithro: these are the initial changes I did https://github.com/aps-sids/gst-plugins-dvswitch/commit/471b9ba7f2d90ed282bcdc5988f2b7f8baf7078a | 07:46 |

| mithro | oh, wait that is your branch :P | 07:48 |
| aps-sids | yeah :P | 07:48 |
| aps-sids | there are more API changes there, I think I need to do those first | 07:49 |
| * shenki reads scrollback | 07:52 | |
| mithro | how can I replicate your compile error? | 07:54 |
| aps-sids | git clone | 07:54 |
| aps-sids | ./autogen.sh | 07:54 |
| aps-sids | make | 07:54 |
| aps-sids | in the porting-to-1.0 branch, of course | 07:55 |
| mithro | aps-sids: on your branch? | 07:55 |
| aps-sids | yes | 07:55 |
| mithro | what are you using to compile on it? | 07:57 |
| *** tija has joined #timvideos | 07:58 | |
| aps-sids | mithro: not sure what you mean. I just do make and get this -- http://paste.ubuntu.com/7802291/ | 08:00 |
| tpb | Title: Ubuntu Pastebin (at paste.ubuntu.com) | 08:00 |
| mithro | my guess at the moment is that when you replaced GST_BOILERPLATE_FULL it left parent_class not in the right place | 08:02 |
| shenki | urgh. gobject != c | 08:07 |
| shenki | :) | 08:07 |
| aps-sids | mithro: found the solution. We need to add "#define gst_dvswitch_src_parent_class parent_class" before G_DEFINE_TYPE_WITH_CODE (in place of GST_BOILERPLATE_FULL) | 08:07 |
| shenki | the way that the source sink is declared is different to the source one | 08:08 |
| shenki | err, the way that the sink class is declared is different to the source one | 08:08 |
| mithro | aps-sids: how did you figure that out? | 08:12 |
| mithro | aps-sids: this is definitely a question that slomo / thaytan is best to answer | 08:15 |
| aps-sids | mithro: I'm reading docs for writing plugins in 0.10 and 1.0 simultaneously :D | 08:16 |
| aps-sids | and also looking through already ported library plugins | 08:16 |
| mithro | yeah | 08:16 |
| mithro | I found https://bugs.webkit.org/show_bug.cgi?id=69630 which seems to do the same | 08:16 |

| shenki | tija: why is the frame rate so low? | 10:47 |
| tija | 100% encoding quality plus I have not added my changed image buffer | 10:48 |
| tija | check the encoded frame size | 10:48 |
| shenki | you should do a blog post with some screenshots ;) | 10:51 |
| shenki | :) | 10:51 |
| shenki | 1.47MB | 10:51 |
| shenki | is that larger than the input? | 10:51 |
| tija | shenki/mithro: Have you done endurance testing of HDMI2USB? When I was testing it sometimes the guvcplayer would give this error " Could not grab image (select timeout): Resource temporarily unavailable" and when I restarted the player things started to work. This error is not reproducible easily | 10:52 |
| shenki | tija: you made the same mistake with verilog as you did with the c files | 10:52 |
| shenki | tija: for the comments | 10:52 |
| shenki | tija: here's a new rule: before you push a commit, you should make sure it builds ;) | 10:53 |
| shenki | tija: hrm, i haven't seen that error | 10:53 |
| tija | shenki: I have a better rule: Before coding add license :P | 10:53 |
| tija | shenki: Image size is highly depended on the kind of image being streamed. | 10:57 |

| aps-sids | CarlFK: cool, you can help with testing gst-dvswitch plugin? | 13:18 |

| aps-sids | CarlFK: Internet is really sloppy here and I don't know exactly how to use dvswitch :( You can take your time, no worries. I'll work on some other components till then. | 13:25 |
| CarlFK | aps-sids: do you have vagrant installed? | 13:26 |

| aps-sids | vagrant up, it downloaded the box and installed it | 14:04 |
| aps-sids | I'm really sorry, I need to leave right now. Just put in the steps, I'll do them later. | 14:05 |
| CarlFK | hmm.. gui or text login? | 14:05 |
| aps-sids | text login | 14:05 |
| aps-sids | whats user and pass? | 14:05 |
| CarlFK | vagrant up should have been the steps. it should have brought up a gui and logged you in... I'll run it here and verify | 14:06 |
| aps-sids | its still downloading some files I guess | 14:06 |
| aps-sids | the updates and all | 14:06 |
| aps-sids | I need to leave now. Will do it later | 14:07 |
