| [04:31:17] | dekarl: | jya, so instead of fixing something it broke something? Again? Oh my |
| [04:33:18] | dekarl: | or are they confirming that the patch is needed and should be backported? |
| [04:35:28] | dekarl: | need to look into it later |
| [04:47:00] | jya: | dekarl: it’s on the user list, “UPNP Media Server No Longer Working†|
| [04:47:24] | jya: | they are saying that the latest upgrade broke it |
| [04:47:50] | jya: | first message was written on May 10th, saying it was working the week earlier |
| [04:48:08] | jya: | there hasn’t been much modification to the fixes/0.27 tree in that time |
| [04:48:58] | jya: | it’s a bit hard to follow on http://www.mythtv.org/pipermail/mythtv-users/ . . . /thread.html |
| [04:49:10] | jya: | because the email client he was using was obviously breaking the thread. |
| [04:49:19] | jya: | in gmail, the whole conversation appears as one thread |
| [04:49:32] | jya: | that’s the first message: http://www.mythtv.org/pipermail/mythtv-users/ . . . /363786.html |
| [04:50:56] | dekarl: | just going through all mails that mention UPNP |
| [04:53:38] | dekarl: | Only change to libupnp on fixes in that time was my backport https://github.com/MythTV/mythtv/commit/e50af . . . 4de4b7e270dc to unbreak it after :( |
| [04:53:47] | dekarl: | looks like it didn't really unbreak it |
| [04:55:37] | gary_buhrmaster: | dekarl: It would be *so* nice if users would learn how to do git bisect to actual confirm/refute patch issues. I will go back to sharpening my stone knives and keeping warm with bearskins now. |
| [04:58:16] | dekarl: | gary_buhrmaster: hey, at least one did post a version number that is newer then my backport |
| [05:01:26] | gary_buhrmaster: | dekarl: Note (for the record), I believe that upnp is so fragile (not just the MythTV implementation) that I am always surprised it works at all between any two devices. The 'net has many stories of interoperability issues. |
| [05:06:20] | jya: | dekarl: yes, John Pilkington said it was working for him (feb build)… once he upgraded, didn’t work |
| [05:06:43] | jya: | we do backport things too quickly …. keep introducing regression in fixes, that’s no good |

| [05:31:52] | gary_buhrmaster: | jya: I will claim (assert) that the (rapid) backporting is a reflection of long release cycles, which is a reflection on the amount of dev resources for full releases (including the QA and user acceptance test cycle). Such is life with a small project with limited resources. I can only offer (limited) moral support. |
| [05:31:58] | dekarl: | jya, meh. its a fix for a fix that is in master only... |
| [05:32:39] | dekarl: | need to add a column to my backport candidates "move along, does not apply to fixes" |
| [05:34:04] | jya: | dekarl: i’m referring to the stuff in fixes/0.27, it’s not just in master |
| [05:36:33] | dekarl: | jya I was reffering to my latest plunder... the commits "chain" from oct 23th, dec 23th, jan 31st ending with my commit applies to master only. It seems I broke UPNP wWhen I backported only the last of that chain |
| [05:36:50] | jya: | i see |
| [05:37:01] | jya: | can’t just reverse that one? |
| [05:37:06] | dekarl: | already done |
| [05:37:07] | jya: | or apply the whole chain i guess |
| [05:37:32] | dekarl: | there's more changes around that code. nothing I can grasp in half an hour :/ |
| [05:41:54] | dekarl: | interesting ways to work around .startsWith('X')... https://github.com/MythTV/mythtv/commit/fa285 . . . ec960b06d682 |
| [05:42:37] | jya: | thats likely faster I would think |
| [05:44:32] | dekarl: | ^- was just a random commit around that chain of fixes for UPNP / Service API |
| [05:44:57] | jya: | well, if the string was null, it would have crashed |
| [05:47:20] | dekarl: | correct, so it does fix something. Maybe thats something for cppcheck "make the code easier to read" department |
| [05:52:38] | jya: | :) |
| [05:53:15] | jya: | why is it what should be a simple task, end up taking me a whole day |
| [05:53:34] | jya: | here I just wanted to test the nouveau driver… only to realise I have errors, not even nouveau devs have seen before |
| [05:53:56] | jya: | and now I’ve wiped out my entire dev box and reinstall 14.04 from scratch |
| [05:56:04] | jya: | weird, I had a very fancy synaptic after upgrading to 14.04… and now after a clean install, it’s back to 1998 ugly |

| [08:05:24] | paul-h: | jya: my vdpau problems appear to be caused by the version of xorg-server I was using 1.15.0 is bad upgrading to 1.15.1 fixed it |
| [08:05:32] | paul-h: | It broke two of my FE's one using vdpau the other using vaapi |
| [08:06:04] | jya: | using nouveau of nvidia drivers? |
| [08:06:11] | jya: | s/of/or |
| [08:06:23] | paul-h: | nvidia drivers |
| [08:06:30] | stuarta: | morning all |
| [08:06:51] | jya: | did you upgrade mythtv at the same time as xorg-server or did myth introduced the regression? |
| [08:07:03] | paul-h: | morning stuarta |
| [08:07:26] | jya: | ‘morning |
| [08:08:26] | paul-h: | jya: It was probably broke a few weeks before your changes and I just never noticed since I dont use the FE on my dev box all that often |
| [08:08:41] | jya: | paul-h: just attempting to determine if the mythtv vdpau code did introduce a problem that wasn’t there before |
| [08:10:04] | paul-h: | I tried my fork which didn't have your changes and the problem was still there so I think it driver related nothing to do with your changes |
| [08:10:10] | ** jya off to dinner, bbl ** | |

| [14:19:23] | dekarl-work: | sphery: can't we generate a full pixel preview at the end of recording/etc and the scale that down to whatever size is currently being asked for? |
| [14:20:50] | dekarl-work: | pulling a picture from the recording each and every time a different resolution is asked for sounds expensive |
| [14:21:14] | sphery: | we used to do a single "standard" sized one at end of recording and scale that one |
| [14:22:02] | sphery: | but then people were disappointed with the quality and said creating new ones doesn't take many resources, so just create them at the desired resolution instead of scaling |
| [14:22:56] | sphery: | we could do it that way, but people will complain no matter which approach |
| [14:24:15] | dekarl-work: | using a standard size of "original size" should satisfy both camps |
| [14:24:56] | sphery: | oh, they'll still complain that "I don't need them, so why are you wasting my storage space" |
| [14:26:03] | sphery: | (for every 4GB recording, you've wasted between 10 and 100kB of my hard drive space because I don't need previews!) |
| [14:26:04] | dekarl-work: | ahh, I'll just wait for you file tracking database refactor. Then rename then pictures to "dot.recordingbasename" and add the hidden attribute for the other os ;) |
| [14:26:18] | sphery: | hehe |
| [14:26:32] | jya: | stuartm: while debugging why the vdpau code fails with the nouveau driver, i stumble upon the MythUI painter drawimage. |
| [14:26:46] | sphery: | but if someone wants to change it to start with a full-res preview and just scale those, we can |
| [14:27:24] | jya: | that code is broken, it attempts to draw into a surface that just doesn’t exists… the nvidia driver handle a call to draw bitmap with an invalid surface fine, but nouveau fail |
| [14:27:52] | jya: | could remove the call to drawimage entirely really.. but is it used ? |
| [14:29:00] | jya: | removing the call completely doesn’t make a difference really |
| [14:30:10] | jya: | or I could go back to the way the 0.22 code worked. It created a default surface taht it used to blend things in, and blend out when painter was deleted |
| [14:31:39] | jya: | my guess is that it slightly increases the memory usage and at some stage having less surface created was a good thing. |
| [14:34:07] | sphery: | dekarl-work: FWIW, though, I'd expect that a large majority of the resources used by mythpreviewgen are for process startup/mythcontext setup/... versus the actual pixmap creation |
| [14:36:03] | sphery: | we're not yet at the point where adding another daemon makes sense, but may be easier/worthwhile if I get around to doing a mythtvd MythTV daemon runner app (to start up whatever daemons are required) |
| [14:37:31] | sphery: | but even if mythpreviewgen were just called to scale the image, it would likely still overwhelm these systems |
| [14:38:18] | sphery: | and we don't want to send a full-res (1920x1080 or 1280x720) preview for each of the 1000+ recordings on the Recorded Programs page and have the browser scale it |
| [14:38:46] | dekarl-work: | ahh, we need to pregenerate "mipmap" style images |
| [14:38:51] | sphery: | so many of these users would still probably have to either enable paging or disable previews |
| [14:39:06] | dekarl-work: | then just pull the correct resolution from the file and send it to the browser :) |
| [14:39:34] | dekarl-work: | adding lazy loading of images to mythweb wouldn't be the worst contribution either. |
| [14:39:51] | dekarl-work: | But I'm not going to beat this dead horse |
| [14:40:22] | sphery: | hehe, or just pre-generate all the possible resolutions--and we'll limit it to only those with proper aspect and force applications that squish previews to wait for doing it wrong |
| [14:41:59] | sphery: | we could probably get away with only having about 16 of the 1x1 previews and share them for all the shows--most users probably won't notice if the color is off by a bit :) |
| [14:44:03] | dekarl-work: | I'm not sure if the lower levels of the mipmap pyramid can be shared between textures. But I like the idea |
| [14:44:15] | sphery: | I suppose the backend could have a GetScaledPreview call and do the scaling itself (we don't need a separate process if it's not playing back video), but this all sounds like a lot of work for people who have chosen underpowered systems because, "I don't need to do anything fancy!" |
| [14:45:50] | dekarl-work: | we could share much of the code with the pregeneration of compressed textures of the images for the OpenGL renderer |
| [14:46:24] | sphery: | (by which I mean I'll let those who choose underpowered systems pay for the decision with their own effort working on making a "show me all 3000 of my recordings on a single web page with a properly-sized pixmap for each one" possible with an underspec'ed system) |
| [14:47:02] | sphery: | especially when they can just enable paging (who really wants to see all 3000 shows on a single page, anyway?) or disable pixmaps with the current code |
| [14:48:29] | sphery: | that said, probably the easiest change would be to add javascript to load images on demand as the user scrolls, like Bing Images does |
| [14:49:02] | dekarl-work: | [16:39] <dekarl-work> adding lazy loading of images to mythweb wouldn't be the worst contribution either. |
| [14:49:08] | dekarl-work: | ;) |
