| CarlFK | melt -profile hdv_720_30p /home/videoteam/Videos/veyepar/lca/lca2017/mlt/Lightweight_inventory_management_with_Pallet_Jack.mlt force_aspect_ratio=@64/45 -consumer avformat:/home/videoteam/Videos/veyepar/lca/lca2017/webm/Lightweight_inventory_management_with_Pallet_Jack.webm progress=1 threads=0 ab=256k vb=2000k quality=good deadline=good deinterlace=1 deinterlace_method=yadif | 01:06 |
| tumbleweed | 30p sounds wrong :) | 01:06 |
| xfxf | ^ that | 01:07 |
| CarlFK | Hmm | 01:07 |
| xfxf | also hdv seems wrong too, and you don't need to deinterlace, it's already progressive | 01:07 |
| tumbleweed | is xfxf freaked aout about that, yet? | 01:07 |
| tumbleweed | ls /usr/local/Shotcut/Shotcut.app/share/mlt/profiles/ | 01:08 |
| tumbleweed | hdv_720_25p ? | 01:09 |
| tumbleweed | that seems to be what we recorded | 01:10 |
| xfxf | all the existing files have been using the hdv_720_30p preview :/ | 01:10 |
| xfxf | but whatever | 01:10 |
| tumbleweed | that's the bit to (not) freak about | 01:10 |
| xfxf | things are in sync, most people aren't going to notice/care | 01:11 |
| tumbleweed | it means end cuts are early which is why CarlFK is looking at this | 01:11 |
| xfxf | ooohh | 01:11 |
| xfxf | oh, wait, wat | 01:11 |
| xfxf | this might explain why i ketp sticking some videos back into the encode queue because they didn't finish at the proper time | 01:11 |
| xfxf | but everything i approved seemed to end correctly | 01:11 |
| tumbleweed | ok | 01:12 |
| xfxf | i'm double checking now | 01:12 |
| tumbleweed | may still be worth re-doing, if there's horrible frame rate conversion | 01:12 |
| tumbleweed | we have the CPU horsepower, I think | 01:12 |
| tumbleweed | I think I haven't hit this before, because wouter wrote us a completely separate encoding script (lol, sadface) | 01:13 |
| CarlFK | I am pretty sure wouters hack re-encoded the mp4 that veyepar/melt created. | 01:13 |
| tumbleweed | lol | 01:14 |
| xfxf | just checked 3 talks, all end at the right time | 01:14 |
| CarlFK | he just wanted to adust the audio levels. | 01:14 |
| xfxf | oh | 01:14 |
| xfxf | i remember what I usually do | 01:14 |
| xfxf | i extended your enc script to read in a second set of upload_formats | 01:14 |
| xfxf | and added a new state | 01:14 |
| tumbleweed | CarlFK: well, we also produce webms, not mp4s | 01:14 |
| xfxf | so i used whatever melt webm stuff was already there | 01:14 |
| xfxf | let me see if I can find my older veyepar install | 01:15 |
| CarlFK | Current Frame: 17473, percentage: 75 | 01:16 |
| CarlFK | that is makeing a webm and going about 1 frame every 2 seconds. | 01:16 |
| CarlFK | Current Frame: 17483, percentage: 75 | 01:16 |
| tumbleweed | CarlFK: what machine? that's crazy slow | 01:17 |
| CarlFK | 30 seconds for 10 frames | 01:17 |
| CarlFK | enc6 (bigbox right?) | 01:17 |
| tumbleweed | yeah | 01:17 |
| CarlFK | it only uses 1 core. but still... | 01:17 |
| CarlFK | melt -profile hdv_720_30p /home/videoteam/Videos/veyepar/lca/lca2017/mlt/Lightweight_inventory_management_with_Pallet_Jack.mlt force_aspect_ratio=@64/45 -consumer avformat:/home/videoteam/Videos/veyepar/lca/lca2017/webm/Lightweight_inventory_management_with_Pallet_Jack.webm progress=1 threads=0 ab=256k vb=2000k quality=good deadline=good deinterlace=1 deinterlace_method=yadif | 01:17 |
| tumbleweed | whatever it's doing seems single threaded | 01:18 |
| tumbleweed | no need to deinterlace | 01:18 |
| CarlFK | pretty sure the encoder is single threaded. threads=0 means "figure it out" | 01:18 |
| tumbleweed | yeah | 01:18 |
| tumbleweed | I seem to remember that the vp8 encoder is | 01:18 |
| tumbleweed | number of threads to use for encoding, can't be 0 [auto] with VP8 | 01:19 |
| tumbleweed | well there you go :P | 01:19 |
| xfxf | ok, just checked what i last used 6 months ago, it's the same | 01:19 |
| CarlFK | what does "can't be 0" mean if I use 0? | 01:19 |
| CarlFK | or should I just follow directions and not use 0 | 01:19 |
| tumbleweed | probably that it doesn't do any automatic guessing | 01:19 |
| xfxf | in veyepar.cfg | 01:19 |
| xfxf | upload_formats=mp4 | 01:19 |
| xfxf | second_upload_formats=webm | 01:19 |
| xfxf | dv_format=hdv_720_25p | 01:19 |
| tumbleweed | aha, we don't have that in our veyepar.cfg | 01:20 |
| CarlFK | I see a #commented out line: | 01:20 |
| CarlFK | cmds=["melt %s -profile dv_ntsc -consumer avformat:%s progress=1 acodec=libvorbis ab=128k ar=44100 vcodec=libvpx minrate=0 b=600k aspect=@4/3 maxrate=1800k g=120 qmax=42 qmin=10"% (mlt_pathname,out_pathname,)] | 01:20 |
| xfxf | that looks like it's for 4:3 DV | 01:20 |
| xfxf | tumbleweed: yeah, second_upload_formats was a hack I added for a second enc.py | 01:21 |
| CarlFK | should we pluck out the codec's and anything else... | 01:21 |
| tumbleweed | CarlFK: I'm fine with threads=0 meaning 1 thread, if we run 12 parallel encoders on bigbox | 01:22 |
| tumbleweed | but more practically, we probably want to bump it to 3 or something | 01:22 |
| tumbleweed | maybe 4 would be rounder | 01:23 |
| CarlFK | right now 1h or vid will take 30 hours to encode | 01:23 |
| tumbleweed | xfxf: we could rope r6mix into encoding... | 01:23 |
| tumbleweed | yeah, that sounds all wrong | 01:23 |
| tumbleweed | kill the deint, specify encoders, and we should be able to get performance up | 01:24 |
| xfxf | webm is definitely slower, the encoder is less optimised | 01:24 |
| tumbleweed | not that slow | 01:24 |
| CarlFK | xfxf: melt -verbose -progress -profile hdv_720_30p /home/videoteam/Videos/veyepar/lca/lca2017/mlt/Decoding_Satellites_with_SatNOGS.mlt -consumer avformat:/home/videoteam/Videos/veyepar/lca/lca2017/mp4/Decoding_Satellites_with_SatNOGS.mp4 threads=4 progressive=1 strict=-2 properties=x264-high ab=256k | 01:24 |
| xfxf | but it's like 4-5x slower, not 50000x slower | 01:24 |
| tumbleweed | hdv_720_30p is still not correct, surely | 01:24 |
| tumbleweed | 25p | 01:24 |
| tumbleweed | and you've got a ,mp4 in there | 01:25 |
| tumbleweed | that's a typo | 01:25 |
| tumbleweed | oh, no, dirt on my monitor :P | 01:25 |
| CarlFK | um.. wut.. right.. hang on... | 01:25 |
| CarlFK | oh right.. that was the messed up ending, not my webm test | 01:26 |
| CarlFK | my bad.. hold please.. | 01:26 |
| xfxf | np, i'll fiddle | 01:27 |
| tumbleweed | if either of you do veyepar.cfg fiddling, please tell me | 01:27 |
| xfxf | by fiddle i mean independent of veyepar | 01:28 |
| xfxf | i'll paste back a better set of params to feed melt | 01:28 |
| CarlFK | I added dv_format=hdv_720_25p to gw1 .../veyepar/dj/scripts/veyepar.cfg | 01:28 |
| CarlFK | Lightweight_inventory_management_with_Pallet_Jack.webm | 01:29 |
| CarlFK | ah, sh.writelines(log_text); self.run_cmd(cmd); sh.close() | 01:32 |
| CarlFK | that is why don | 01:32 |
| CarlFK | that is why don't see the line that is still running | 01:33 |
| CarlFK | tumbleweed: rsyncing? | 01:33 |
| CarlFK | I am going to go to green room and get food | 01:33 |

| micolous | tumbleweed: tasman A is losing sync again | 02:31 |
| tumbleweed | micolous: yays | 02:31 |
| tumbleweed | I see high WER | 02:32 |
| tumbleweed | new cable? | 02:32 |
| micolous | the av people here are on the phone | 02:32 |
| micolous | I assume with someone else in noc | 02:32 |
| micolous | It's come good again now | 02:33 |
| tumbleweed | WER is back to zero | 02:33 |
| micolous | It glitched out again for about a second | 02:36 |
| tumbleweed | dvisampler0: ph: 22 18 18 // charsync:111 [3 3 3] // WER:5199 0 0 // chansync:1 // res:1280x0 | 02:36 |
| tumbleweed | then back to 0 | 02:36 |
| tumbleweed | oh, high again | 02:36 |
| micolous | Yeah, it's stuck bad | 02:36 |
| tumbleweed | we need to change that cable, I think | 02:36 |
| micolous | I think tell AV to change cable | 02:36 |
| micolous | yeah | 02:36 |
| tumbleweed | our cable, not theirs | 02:36 |
| jea | i did `input0 on` earlier to fix the continuous problem | 02:36 |
| tumbleweed | but yeah | 02:37 |
| micolous | They're on the phone | 02:37 |
| micolous | Did they put in their own cable? | 02:37 |
| tumbleweed | I mean, this is our problem, not theirs | 02:37 |
| micolous | Speaker is persisting | 02:38 |
| micolous | As best they can | 02:38 |
| jea | i can't do input0 on continuously unfortunately | 02:38 |
| tumbleweed | is anyone in the noc doing anything about a new cable? | 02:38 |
| jea | the last time i did it, nothing fixed it | 02:39 |
| tumbleweed | not that I'm sure it'll help | 02:39 |
| tumbleweed | but Iv'eb ene threatening to replace it for a couple of days now | 02:39 |
| jea | i'm the only one in the noc at the moment. will a new cable actually work? | 02:39 |
| tumbleweed | it's worth a shot, if nothing else | 02:39 |
| tumbleweed | another opsis is another option | 02:39 |
| jea | yeah, it goes bad as soon as i do input0 on | 02:39 |
| jea | i don't like interrupting talks, but maybe i need to for this on | 02:39 |
| tumbleweed | I'm going to come and do a cable swap | 02:39 |
| jea | ok | 02:39 |
| jea | it just went back to normal | 02:40 |
| jea | without me changing anything | 02:40 |
| * tumbleweed has swapped the cable | 02:47 | |
| tumbleweed | I put the opsis from wellington 2 on top of the one we're currently using | 02:47 |
| tumbleweed | next thing to try is the other opsis | 02:47 |
| jea | ok, thanks for that | 02:49 |
| jea | cable seems to have fixed a lot of it already, so hopefully that will be enough | 02:50 |
| tumbleweed | that cable goes in the bin then | 02:50 |
| tumbleweed | or into tim's bag of "interesting" cables | 02:50 |
| jea | yeah, give it to tim | 02:52 |
| jea | i wonder if it was one of his new ones or not | 02:52 |
| jea | was it a white one? | 02:52 |
| tumbleweed | black | 02:52 |
| jea | ok | 02:52 |
| tumbleweed | the two in room X are white | 02:52 |
| CarlFK | there are black magic cables? | 02:52 |
| tumbleweed | CarlFK: yep, and red, and blue | 02:52 |
| jea | now i'm trying to remember if tim's unopened ones were black or white | 02:53 |
| tumbleweed | black 3ft I think | 02:53 |
| jea | tumbleweed: i've never heard of a bluemagic. where can i buy one? | 02:53 |
| tumbleweed | I think carl has one :) | 02:53 |
| jea | what outputs does it have? | 02:54 |
| tumbleweed | magical ones? | 02:54 |
| CarlFK | hdmi to rj45 | 02:54 |
