xfxfCarlFK: can you kill melt on all devices?21:27
xfxfI just killed it on Plenary PC, robbing resources21:27
xfxftumbleweed: the stop/start all.the things script appears to have a typo for the monitoring stuff, says hdmi2usmbond21:28
xfxftumbleweed: issues with PC in Plenary, voctocore isn't starting properly21:30
tumbleweedxfxf: I'll visit21:32
tumbleweedyeah, I noticed that too (re typo)21:33
tumbleweedalso, plenary obviously doesn't have an opsis21:33
*** nrossi has joined #timvideos21:34
xfxfmithro: we can't move podiums due to lights, can you swap the opsis's21:39
xfxf why are we doing streaming encoding on the mixing machine??22:25
xfxfthis is why CPU is depleted22:25
xfxfCarlFK, tumbleweed22:25
xfxfThis might be stuffing up recordings.22:26
xfxfwe usually do it on another machine, i.e. the podium one, or a  server in another room22:28
thaytanohai22:32
thaytanxfxf, what's your encoding format?22:33
jeathaytan: this is our script https://raw.githubusercontent.com/xfxf/video-scripts/master/michael/youtube-live.sh22:33
jeathaytan: I don't know enough about it to tweak parameters, but happy to take suggestions22:34
jeaxfxf: streaming is now running from a laptop here for the plenary22:34
xfxfjea - awesome, ta. Is it maxing CPU?22:34
jeaxfxf: actually no, it died22:34
jealet me see if i can get it back22:35
xfxfbe careful22:35
xfxfit might cause that ingest to break if we are hitting all cpu22:35
xfxfI'm happy to can streaming now and play in break22:35
jeai am only running commands on this laptop, not on the mix box22:35
xfxfIs this one of the opsis's laptops?22:35
xfxfOr a spare?22:35
xfxfIf the latter go for it22:36
jeathe monitoring laptop, so spare22:37
thaytanxfxf, jea: well can probably control max cpu usage with the threads= property on x264enc. It'll spawn 1 thread per CPU core by default, so can max out the CPU if it's near encoding limits22:37
thaytanbut also we could experiment with using vaapiencode where it's available and do encoding on the GPU22:37
xfxfthe caveat here is this is untested, so I want to avoid playing with machines that are currently recording22:37
xfxfLet's test on a room that isn't live at the moment before we go ahead with anything22:37

xfxfI'd leave Plenary alone TBh22:37
xfxfWe have 5 other rooms to screw with for the next hour and a bit22:38
jeayes, that is fine22:39
xfxfthx22:39
jeathaytan: that sounds alright. i've put in the threads parameter, and it certainly helps with CPU. would you be able to let me know what things to try out please?22:41
xfxfjea: as part of your test, validate the saved files on the local machine.  the biggest thing I'm paranoid about is CPU depletion causing video not to be written out properly22:42
jeaInterestingly when I run the stream from another laptop, pipeline0 will give EOS after a short time22:42
thaytanjea, run it how? view it for playback?22:52
thaytanis it timing out?22:52
thaytanwhich version of GStreamer are you using?22:55
thaytan(gst-inspect-1.0 --gst-version)22:55
thaytanand does your distro have gstreamer1.0-vaapi ?22:56
jeathaytan: GStreamer Core Library version 1.8.222:57
thaytanOK cool22:57
jeatrying to find the vaapi bit now22:57
thaytanjea, apt-cache search vaapi22:59
jeathaytan: yep, it is available. we are running Ubuntu 16.04.1, but minimal set of packages (can install more if needed)23:00
jeasetting the thread limit has helped a lot23:00
thaytanOK, there's an option there for testing then23:00
jeacool, that would great to try23:01
thaytanjea, to try it, just install gstreamer1.0-vaapi, check you have vaapih264enc (gst-inspect-1.0 vaapih264enc) then replace x264enc with vaapih264enc in the pipeline23:12
thaytanwith slightly different encoder params23:12
thaytanlike vaapih264enc bitrate=2000 keyframe-period=60 max-bframes=0 at least23:13
thaytanlooking at aud=true atm. I'm not sure if vaapi does access unit delimiters by default23:13
thaytanhmm, I think it doesn't do AUD23:21
