| [03:49:45] | peterbennett: | gigem: I don't know what freetype2 is and why it is needed. It gets disabled when I build for Linux . Your patch seems fine, I seem to have messed up the handling of freetype2 with the ffmpeg refresh. |

| [08:53:48] | stuarta: | well i can safely say that fedora arm isn't working very well for me right now |
| [08:54:01] | stuarta: | it's taken over 12hours to not complete running some updates |
| [08:54:11] | stuarta: | mainly due to dnf spinning, rather than rpm taking it's time |

| [15:07:42] | peterbennett: | stuarta: Don't buy it, I can send you a pdf |
| [15:10:50] | peterbennett: | stuarta: I have a bunch of Raspberry Pi Multimedia documentation in pdf including that book, if you are interested. |
| [15:11:18] | kwizart: | stuarta, dnf is fast on fedora-arm with me, but there is a need to have a fast sdcard |
| [15:12:53] | kwizart: | FYI, I plan to test mythfrontend on trimslice at some point, there is a vdpau backend support (upstream with linux 4.16) |
| [15:13:15] | kwizart: | and a re-enginered gpu (wip) |
| [15:14:56] | stuarta: | kwizart: i'm using class10 sd card's for all the different distro's i'm trying, and fedora is by far the slowest |
| [15:17:06] | kwizart: | stuarta, which spin have you tried, I think I've found that some partition was not sector aligned, I don't know if it's fixed in recent spins |
| [15:18:20] | kwizart: | stuarta, only tried with the pi ? I think it also miss few critial component upstream. a cpufreq driver among other |
| [15:20:15] | stuarta: | the cpufreq driver does make some sense, despite dnf spinning for 12hrs, the cpu was cool, like it's running at minimum |
| [15:21:38] | kwizart: | yep, but 12hours for a task is still huge, I'm not sure I've reproduce on my spin which is a regular desktop spin with xfce |
| [15:22:09] | stuarta: | it's just f27 workstation, iirc pulled from the fedora arm page |
| [15:22:20] | stuarta: | not the aarch64 variant |
| [15:22:29] | stuarta: | fyi, trimslice is eol |
| [15:23:04] | kwizart: | sure, however I'm a lucky owner of one of them along with ac100 (same tegra2 SOC) |
| [15:23:37] | stuarta: | lucky you |
| [15:25:03] | stuarta: | i may try re-blasting the sd card with a new install of fedora |
| [15:28:23] | stuarta: | quite frankly it can't get any worse :( |
| [15:45:31] | peterbennett: | stuarta: In my experience, the thing to watch out for is swapping in the raspberry pi, since it has only 1 GB memory |
| [15:46:14] | stuarta: | been keeping an eye on that |
| [15:46:30] | peterbennett: | Once it starts swapping everything will take 100 times longer, it is completely unusable. |

| [16:01:09] | warpme: | hi guys! |
| [16:03:32] | warpme: | peterbennett: I'm trying to bisect #13223 vdpau playback issue using ffplay. Interestng is that ffplay from ffmpeg3.2.3 also fails – while myth based on ffmpeg3.2.3 plays ok (IIRC before resync to 3.4.1 myth was on 3.2.3 right?) |
| [16:03:32] | ** MythLogBot http://code.mythtv.org/trac/ticket/13223 ** | |
| [16:03:57] | warpme: | bisect – i mean ffmpeg bisect |
| [16:05:46] | peterbennett: | warpme: I believe that ffplay does not support vdpau. It only has one screen output type that is based on OpenGL. Since vdpau decoding cannot be combined with other screen output, it does not work. |
| [16:07:58] | warpme: | peterbennett: ok I see. Have You any idea what I can use as player to bisect ffmpeg then? |
| [16:09:32] | warpme: | btw: is myth using hwaccell api from ffmpeg or rather old depreciated standalone vdpau decoder? |
| [16:10:56] | peterbennett: | I am not sure. Ptrobably older. |
| [16:12:47] | peterbennett: | I was looking for a player myself to try it on. But it looks like mplayer uses an older ffpmeg. i did install latest master of VLC but I am not sure which ffmpeg that uses. |
| [16:13:53] | warpme: | ough – if older standalone vdpau decoder – then ffmpeg guys saying me "you should expect all king of problems when you are using depreciated standalone vdpau decoder". damn.... |
| [16:14:20] | stuarta: | they seem to want you to use nvdec now |
| [16:14:26] | stuarta: | nvdec / nvenc |
| [16:15:46] | warpme: | yes. i see this. after ffmpeg3.4.2 there is no vdpau at all... |
| [16:16:55] | warpme: | it looks like 3.4.2 is last possible ffmpeg for us. Any newer will need switch myth player to nvdec.... |
| [16:18:48] | warpme: | regarding player to do bisecting: indeed we need player wich also uses standalone vdpau and can be build with external ffmpeg. ough |
| [16:20:28] | warpme: | I'll probably end with mplayer – I have old infrastructure to build it with external ffmpeg. geez so many work just to hunt one playback issue |
| [16:23:35] | warpme: | but maybe there is more basic Q: is this playback issue an issue of ffmpeg or maybe rather our integration of ffmpeg into mythtv? |
| [16:24:45] | stuarta: | heh, well, we do need to rework our handling of hwaccell |
| [16:24:58] | stuarta: | currently we completely ignore the framework ffmpeg provide and do our own thing |
| [16:37:27] | peterbennett: | warpme: I wish I knew the answer. |
| [16:38:39] | peterbennett: | Also, mplayer may use a different call method that works differently |
| [16:40:19] | peterbennett: | warpme: Maybe best is to find what is different about those files that won't play, then maybe we can search for an answer |
| [16:45:48] | warpme: | peterbennett: indded delta in input was also my idea to find root casue. then i was thinking ffmpeg guys maybe will hint me...but when they told me "if you are using depreciated standalone vdpau decoder – then forget about our attention/help" – then i started to think that even if i will find delta in inputs – translating this to code will again need ffmpeg guys help – but they will not help. so bisecting seems to be only route |
| [16:54:40] | warpme: | first thing i think will be to try mplayer with external 3.2.3 and 3.4.1 ffmpegs and see – can we catch issue. if yes – then we are in home. if not (i mean mplayer will play ok on both) then too bad as this will mean bisecting different ver of ffmpeg in myth.... |
| [16:58:11] | warpme: | peterbennett: btw: proably you saw my comment to #13223: fall-back gives me black screen with fe hang when fe falls-back to software decode. |
| [17:01:11] | stuarta: | warpme: that with the opengl painter? |
| [17:07:21] | warpme: | yes |
| [17:07:48] | warpme: | it is set to auto – but looking on log it is opengl |
| [17:08:30] | warpme: | glprovider is nvidial blob (340.106) |
| [17:09:26] | stuarta: | does the black screen persist when forcing qt painter? (i suspect this will also force non hwaccel) |
| [17:16:28] | warpme: | with qt painer it fall-back ok. |
| [17:16:54] | warpme: | so issue is with opengl fall-back |
| [17:23:02] | stuarta: | hmmm, make -j8 goes pretty quickly on this new machine |
