| tumbleweed | xfxf: I'll visit | 21:32 |
| tumbleweed | yeah, I noticed that too (re typo) | 21:33 |
| tumbleweed | also, plenary obviously doesn't have an opsis | 21:33 |
| *** nrossi has joined #timvideos | 21:34 | |
| xfxf | mithro: we can't move podiums due to lights, can you swap the opsis's | 21:39 |
| xfxf | why are we doing streaming encoding on the mixing machine?? | 22:25 |
| xfxf | this is why CPU is depleted | 22:25 |
| xfxf | CarlFK, tumbleweed | 22:25 |
| xfxf | This might be stuffing up recordings. | 22:26 |
| xfxf | we usually do it on another machine, i.e. the podium one, or a server in another room | 22:28 |
| thaytan | ohai | 22:32 |
| thaytan | xfxf, what's your encoding format? | 22:33 |
| jea | thaytan: this is our script https://raw.githubusercontent.com/xfxf/video-scripts/master/michael/youtube-live.sh | 22:33 |
| jea | thaytan: I don't know enough about it to tweak parameters, but happy to take suggestions | 22:34 |
| jea | xfxf: streaming is now running from a laptop here for the plenary | 22:34 |
| xfxf | jea - awesome, ta. Is it maxing CPU? | 22:34 |
| jea | xfxf: actually no, it died | 22:34 |
| jea | let me see if i can get it back | 22:35 |
| xfxf | be careful | 22:35 |
| xfxf | it might cause that ingest to break if we are hitting all cpu | 22:35 |
| xfxf | I'm happy to can streaming now and play in break | 22:35 |
| jea | i am only running commands on this laptop, not on the mix box | 22:35 |
| xfxf | Is this one of the opsis's laptops? | 22:35 |
| xfxf | Or a spare? | 22:35 |
| xfxf | If the latter go for it | 22:36 |
| jea | the monitoring laptop, so spare | 22:37 |
| thaytan | xfxf, 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 limits | 22:37 |
| thaytan | but also we could experiment with using vaapiencode where it's available and do encoding on the GPU | 22:37 |
| xfxf | the caveat here is this is untested, so I want to avoid playing with machines that are currently recording | 22:37 |
| xfxf | Let's test on a room that isn't live at the moment before we go ahead with anything | 22:37 |

| xfxf | I'd leave Plenary alone TBh | 22:37 |
| xfxf | We have 5 other rooms to screw with for the next hour and a bit | 22:38 |
| jea | yes, that is fine | 22:39 |
| xfxf | thx | 22:39 |
| jea | thaytan: 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 |
| xfxf | jea: 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 properly | 22:42 |
| jea | Interestingly when I run the stream from another laptop, pipeline0 will give EOS after a short time | 22:42 |
| thaytan | jea, run it how? view it for playback? | 22:52 |
| thaytan | is it timing out? | 22:52 |
| thaytan | which version of GStreamer are you using? | 22:55 |
| thaytan | (gst-inspect-1.0 --gst-version) | 22:55 |
| thaytan | and does your distro have gstreamer1.0-vaapi ? | 22:56 |
| jea | thaytan: GStreamer Core Library version 1.8.2 | 22:57 |
| thaytan | OK cool | 22:57 |
| jea | trying to find the vaapi bit now | 22:57 |
| thaytan | jea, apt-cache search vaapi | 22:59 |
| jea | thaytan: yep, it is available. we are running Ubuntu 16.04.1, but minimal set of packages (can install more if needed) | 23:00 |
| jea | setting the thread limit has helped a lot | 23:00 |
| thaytan | OK, there's an option there for testing then | 23:00 |
| jea | cool, that would great to try | 23:01 |
| thaytan | jea, to try it, just install gstreamer1.0-vaapi, check you have vaapih264enc (gst-inspect-1.0 vaapih264enc) then replace x264enc with vaapih264enc in the pipeline | 23:12 |
| thaytan | with slightly different encoder params | 23:12 |
| thaytan | like vaapih264enc bitrate=2000 keyframe-period=60 max-bframes=0 at least | 23:13 |
| thaytan | looking at aud=true atm. I'm not sure if vaapi does access unit delimiters by default | 23:13 |
| thaytan | hmm, I think it doesn't do AUD | 23:21 |
