| thaytan | For a while now, Jaycar have had a bin here with 2m HDMI cables for $10 | 06:00 |
| thaytan | and ALDI were selling nice 8m ones recently. I've been using one of those for running 1080p from the mediacenter at the back of the room to the TV | 06:01 |
| xfxf | thaytan: turns out we need amp'ed cables, proving fun to locate | 06:05 |
| deeprave | CarlFK: | 06:07 |
| CarlFK | deeprave: ? | 06:08 |
| deeprave | CarlFK: just added carl/hu-conf-serial.py to the video-scripts repo. No longer uses flterm but uses pyserial (module needs to be installed obviously) | 06:08 |
| deeprave | as opposed to the flterm method, it actually works. uses a .1 sec delay between chars sent | 06:09 |
| CarlFK | neat | 06:09 |
| thaytan | xfxf: cables with an amplifier in? never seen those | 06:09 |
| xfxf | thaytan: neither had i | 06:14 |
| xfxf | CarlFK: deeprave's script also works with the Opsis's, the thing you had before doesn't | 06:14 |
| xfxf | herm, trying to compile that c file, missing gst.h, thought it'd be in libgstreamer1.0-dev | 06:15 |
| CarlFK | it is the $6 I linked above | 06:16 |
| thaytan | xfxf, gcc `pkg-config --cflags gstreamer-1.0` `pkg-config --libs gstreamer-1.0` -o netclock-client netclock-client.c oughtta do it | 06:17 |
| thaytan | what distances are you talking that you need an amp in the cable? | 06:19 |
| thaytan | that one is 1m long, which seems too short to make a difference | 06:19 |

| CarlFK | thaytan: we keep hearing things like "This hdmi splitter makes things much better when it works. but getting it to work requires way to much fiddling so it's out." | 06:27 |
| thaytan | CarlFK, we saw a bit of that sort of thing in Dublin for GStreamer conf | 06:27 |
| thaytan | the rooms had a HDMI transmitter/splitter to the projector and the ubicast streaming guys | 06:28 |
| xfxf | thaytan: still having issues compiling it, i was getting help but that person has been diverted | 06:28 |
| thaytan | and it'd work for some people and not others | 06:28 |

| thaytan | xfxf, we're getting into dinnertime here now - I'll bbl | 07:37 |
| xfxf | no worries | 07:38 |
| xfxf | MaZderMind is the developer, MaZderMind we may as well continue any discussion about this here so it's not confusing (thaytan is the gstreamer dev who has been helping me) | 07:38 |
| xfxf | this might be relevant: <@MaZderMind> i don't know how to set the base-time correct for remote sources. as i said earlier we have never tested remote sources | 07:38 |
| thaytan | xfxf, add 'gstreamer-net-1.0' as a pkg-config pkg to pull in | 07:39 |
| thaytan | sorry | 07:39 |
| thaytan | does voctomix depend on the base time? | 07:39 |
| thaytan | how does it normally distribute base time? | 07:39 |
| xfxf | MaZderMind: ^^ | 07:39 |
| thaytan | I guess it would have to to get precisely synched mixing | 07:40 |
| thaytan | independent of capture and transmission delays | 07:40 |
| xfxf | oh cool, the compile worked, thanks | 07:40 |
| thaytan | but if you're sending matroska, don't the timestamps of any incoming feed always start at 0? | 07:40 |
| mithro | thaytan: it's suppose to be mostly independent of time | 07:41 |
| thaytan | oh, matroska preserves the input timestamps | 07:42 |
| thaytan | so that'd work | 07:42 |
| xfxf | this is pretty much the only remaining issue preventing us from using vocto, btw | 07:42 |
| xfxf | so appreciate++ the help | 07:42 |

| thaytan | xfxf, I want you to check if you get clock synch (stats output + synchronised=(boolean)true) when talking to the vocto clock IP + port | 08:15 |
| xfxf | that is the vocto clock IP + port, and I can see the above | 08:16 |
| xfxf | in that pastebin | 08:16 |
| xfxf | synchronised starts off as false, but then is true | 08:16 |
| xfxf | oh, actually, you said in the python script before trying to sync clocks to wait a bit? i'll try that too, i forgot you mentioned that | 08:17 |
| thaytan | xfxf, I want to hear what MaZderMind has to say about Vocto's basetime requirements | 08:18 |
| xfxf | ok, np | 08:19 |
| thaytan | one easy thing vocto can do there is to always use a basetime of 0 everywhere | 08:20 |
| thaytan | that's easy to transmit a priori | 08:20 |

| xfxf | i rearranged the script so the sync_clock() is under the set_state(PLAYING), with a time.sleep(3) under it | 08:25 |
| xfxf | zero idea if this does what i want, but i'm getting video | 08:25 |
| xfxf | as you say i'm interested to see your discussion w/ MaZderMind | 08:25 |
| xfxf | i'm just guessing | 08:25 |
| thaytan | no, you have to set the clock before playing | 08:28 |
| thaytan | or else it has no effect and you're using the default clock, which should be the system clock | 08:29 |
| xfxf | okay, will revert that then | 08:29 |
| xfxf | a time.sleep() didn't make any difference alone btw | 08:29 |
| thaytan | once the pipeline gets to playing state (confirmed by the state-changed bus mesage), you can see which clock it chose with pipeline.get_clock() | 08:29 |

| mithro | _florent_: doesn't seem to have made any difference I can see | 08:35 |
| MaZderMind | I'm just now reading backlog here | 08:36 |
| MaZderMind | thaytan: Up until now we used voctomix just on one system, so all pipeliens running on the same systemclock | 08:37 |
| MaZderMind | thaytan: In the nettime-branch (see https://github.com/voc/voctomix/pull/51/files) I added a SystemClock to the core and really forced all pipelines to use this. I then added a NetTimeProvider which provides this clock onto the network. I then added code to the GUI to obtain this clock from the server and apply it to all pipeliens. | 08:43 |
