| [13:02:02] | markspieth: | re #12902 QOpenGLContext can try to moveToThread but that may not work |
| [13:02:02] | ** MythLogBot http://code.mythtv.org/trac/ticket/12902 ** | |
| [13:02:24] | markspieth: | have similar issue for android which I havent had time to resolve yet. |
| [13:02:51] | markspieth: | It sound like form the doco that you may need a dispatcher thread not a standard thread. |
| [13:03:21] | markspieth: | Ive been using 5.7.1 (pre) |
| [13:03:30] | markspieth: | in my tests but no good so far |
| [13:04:04] | markspieth: | also dont know how sharedContexts are related either |
| [13:05:29] | markspieth: | may need multiple contexts one per thread or provide some sort of locking/resource management to thread slice it |
| [13:05:59] | markspieth: | I dont think this is of much help though |
| [13:28:21] | stuarta: | interesting observations |

| [14:46:56] | stuarta: | markspieth: i'm more interested in why the code feels it needs todo the makeCurrent() in the first place |
| [14:52:28] | stuarta: | more specifically, given that nobody has reported issues with the primary deinterlacing method in this respect, why is the backup deinterlacer code doing what it does |

| [15:12:54] | stuarta: | i mean, we have a VideoOutputNull class, wtf is that for? /dev/null for video? |
| [15:14:47] | stuarta: | initial commit history is from 2003, so it's pretty old |
| [15:19:44] | stuarta: | i also note the oddity that there is a mythrender for D3D9, OpenGL & VDPAU, but not VAAPI |
| [15:22:42] | stuarta: | i suspect that's due to use of opengl with vaapi, /me continues thinking out loud |

| [15:29:33] | jheizer: | layers upon layers with many options |
| [15:30:45] | stuarta: | i seriously despair sometimes when i look at this code, how exactly is anybody supposed to try to understand it, in order to fix bugs / improve it?? |
| [15:32:01] | stuarta: | maybe it's time to drop some more of these calls around the code and see what happens https://code.mythtv.org/cgit/mythtv/tree/myth . . . api.cpp#n134 |
| [15:32:54] | jheizer: | lol |
| [15:33:10] | stuarta: | if (!gCoreContext->IsUIThread()) dont_bloody_call_makeCurrent |
| [15:33:18] | jheizer: | trying to figure out if my pi builder has had a successful build since I swap them |
| [15:33:19] | stuarta: | and see wtf breaks |
| [15:33:21] | jheizer: | since it just failed again |
| [15:33:32] | stuarta: | the compiler is ICE'ing |
| [15:33:52] | stuarta: | well failing, and it's on tvplay, so i'm wondering if that's too big... |
| [15:34:51] | jheizer: | free mem now, but swap is full so it might have filed then and caused it |
| [15:34:57] | stuarta: | heh |
| [15:34:58] | jheizer: | *filled |
| [15:38:08] | jheizer: | stopped a service I'm not using anymore and freed 20% of total ram so see if that helps. |
| [15:42:10] | stuarta: | it's running a build now, so lets see how that goes |
