| mithro | CarlFK, back now | 01:30 |
| mithro | CarlFK, I think you meant https://github.com/timvideos/dvsource-v4l2-other | 01:31 |
| tpb | Title: timvideos/dvsource-v4l2-other · GitHub (at github.com) | 01:31 |
| mithro | CarlFK, send a pull request and I'll merge | 01:31 |
| CarlFK | mithro: im back too | 01:55 |
| CarlFK | pull requests coming up | 01:55 |
| CarlFK | mithro: I am trying to add audio to the test feed | 02:03 |
| mithro | CarlFK, I don't really want to add audio to the test feed | 02:03 |
| CarlFK | why not? | 02:03 |
| mithro | CarlFK, because the *real* source will never have audio | 02:04 |
| mithro | CarlFK, I would be happy for a dvsource-test source type thing | 02:04 |
| mithro | CarlFK, I'm already in progress to split dvsource-v4l2-other into a library and dvsource-v4l2-other and dvsource-gst | 02:04 |
| mithro | CarlFK, I assume you actually want a dvsource-fake ? | 02:07 |
| CarlFK | my first goal is to get rid of the red ! | 02:07 |
| CarlFK | a real dv cam does have audio | 02:07 |
| CarlFK | so I think the v4l needs to supply something, even if it is just silence | 02:08 |
| mithro | CarlFK, sorry went to lunch | 03:12 |
| mithro | CarlFK, back now, you still around? | 03:12 |
| CarlFK | yep | 03:12 |
| mithro | CarlFK, can you send a screenshot of the red ! | 03:14 |
| mithro | CarlFK, I'm on a pretty old dvswitch, so don't get anything like that | 03:15 |
| CarlFK | mithro: ever seen what happens if you don't set the audio on the camera and twinpact to the same bitrate? | 03:15 |
| mithro | CarlFK, nope! | 03:15 |
| CarlFK | hmm | 03:15 |
| mithro | CarlFK, is that even possible? I thought DV only had one bitrate for audio? | 03:16 |
| mithro | s/DV/standard compliant DV/ | 03:16 |
| CarlFK | do you have a twinpact handy? | 03:16 |
| CarlFK | Switch B,4 - 48kHz 16 bit / 32kHz 12 bit | 03:17 |
| CarlFK | 16 bit is 2 chan, 12 bit is 4 | 03:18 |
| mithro | CarlFK, not at this very second | 03:20 |
| mithro | wow you are correct | 03:20 |
| mithro | Audio can be stored in either of two forms: 16-bit Linear PCM stereo at 48 kHz sampling rate (768 kbit/s per channel, 1.5 Mbit/s stereo), or four nonlinear 12-bit PCM channels at 32 kHz sampling rate (384 kbit/s per channel, 1.5 MBit/s for four channels). In addition, the DV specification also supports 16-bit audio at 44.1 kHz (706 kbit/s per channel, 1.4 Mbit/s stereo), the same sampling rate used for CD audio.[7] In practice, the | 03:20 |
| mithro | 48 kHz stereo mode is used almost exclusively. | 03:20 |
| mithro | CarlFK, so what happens if you give dvswitch different audio formats? | 03:22 |
| CarlFK | http://veyepar.nextdayvideo.com/site_media/static/veyepar/temp/dvsbang.png | 03:22 |
| tpb | <http://ln-s.net/AXSp> (at veyepar.nextdayvideo.com) | 03:22 |
| CarlFK | normally dvswitch will use the first source as a reference, and check that additional sources match it so that you can switch between them | 03:23 |
| CarlFK | if the additional ones are off, red (!) on the thumb | 03:23 |
| CarlFK | I am surprised that the first source is throwing that | 03:23 |
| mithro | CarlFK, okay - I'll add an empty audio source | 03:25 |
| CarlFK | yay. | 03:25 |
| mithro | CarlFK, silence okay? Or do you need an actual tone? | 03:28 |
| CarlFK | I would prefer a tone | 03:28 |
| CarlFK | test the VU meeter (did you see how lilttle it is?) | 03:28 |
| mithro | umm.... | 03:29 |
| mithro | -d, --rate=48000|32000|44100 | 03:29 |
| mithro | Specify the sample rate, in Hz. The default is 48000. | 03:29 |
| mithro | -d, --delay=DELAY | 03:29 |
| mithro | Specify the time by which audio should be delayed, in seconds. The delays in live audio and video sources need to be closely matched | 03:29 |
| mithro | in order that the audio and video signals will be synchronised in the output of DVswitch. The default is 0.2. | 03:29 |
| CarlFK | Usage: dvsource-alsa [-h HOST] [-p PORT] [-s ntsc|pal] \ | 03:29 |
| CarlFK | [-r 48000|32000|44100] [-d DELAY] [DEVICE] | 03:29 |
| CarlFK | my pull request was to change your -? to -s (for system) | 03:30 |
| CarlFK | but I pretty much need to fork, clone, edit, test, commit, push and pull request | 03:30 |
| CarlFK | can you just change -f --format to -s --system (and the 2 or so places .format is used ? | 03:31 |
| mithro | CarlFK, is --system read from the config file in some way? | 03:34 |
| CarlFK | yes - just like host and port | 03:37 |
| mithro | CarlFK, what is the name? MIXER_HOST and MIXER_PORT | 03:38 |
| CarlFK | good q.. maybe I am wrong about that.. looking at the source a 2nd time https://alioth.debian.org/plugins/scmgit/cgi-bin/gitweb.cgi?p=dvswitch/dvswitch.git;a=blob;f=src/dvsource-alsa.c;h=692983b6358d01a10a78f0f1139eb61312f656ea;hb=HEAD | 03:41 |
| tpb | <http://ln-s.net/AXTK> (at alioth.debian.org) | 03:41 |
| CarlFK | hey look, you can put a file here too: read_config("/etc/dvswitchrc" | 03:48 |
| mithro | CarlFK, yeah, I found that part | 03:58 |
| CarlFK | mithro: here is what I got from #gstreamer http://pastebin.com/4AVu35E0 | 04:23 |
| tpb | Title: gst-launch-0.10 videotestsrc is-live=true pattern=18 ! queue leaky=2 max-si - Pastebin.com (at pastebin.com) | 04:23 |
| mithro | CarlFK, it looks like gstreamer doesn't support the 12bit format of DV audio | 04:24 |
| mithro | (as in can't generate it) | 04:24 |
| CarlFK | that is pretty much OK | 04:26 |
| CarlFK | I am the only one that tried to use it.. I was hoping to be able to save 4 audio tracks from different sources | 04:27 |
| CarlFK | now I just use audio cables to do that mixing and save 2 mono tracks - 1 from the sound board, one from a mic on the camera | 04:28 |
| mithro | CarlFK, why don't you just use a USB mixer thingy? | 04:37 |
| mithro | CarlFK, btw it doesn't look like you are on the dvswitch branch | 04:38 |
| CarlFK | usb mixer - I have stopped using "that" (for various values of that) and gone with pugging mixer out into 1 channel of the camera's audio in. and then use the mic on the camera for the 2nd channel. | 04:40 |
| CarlFK | . when I encode, I copy channel 1 over channel 2 | 04:40 |
| CarlFK | but if channel 1 is ever broken, I can use channel 2 | 04:41 |
| CarlFK | it will suck, but it is better than nothing | 04:41 |
| mithro | CarlFK, do you have "gst-inspect-1.*" on your system ? | 04:47 |
| CarlFK | yes - lots of output | 04:48 |
| CarlFK | want to see? | 04:48 |

| mithro | CarlFK, okay - that confirms it has the same bug I'm seeing | 04:57 |
| mithro | CarlFK, looks like 44.1kHz doesn't work either.... | 05:22 |
| CarlFK | how about 48k? | 05:25 |
| mithro | 48k works | 05:29 |

| NickB | Yep, that's the one, LG500, http://www.wklaser.com/pro_183.aspx | 08:09 |

| NickB | and the big brother LC1290 | 08:09 |
| mithro | I've sent an enquiry to G.Weike/wklaser about getting the LG500(DESK) model | 08:16 |
| mithro | they are currently getting me a price for door-to-door shipping | 08:25 |
| NickB | mithro: Replied, for introduction/posterity. | 08:26 |
| NickB | Looks like JINAN G WEIKE SCIENCE | 08:26 |
| NickB | ...shipped straight to us? | 08:27 |
| NickB | via Singapore | 08:27 |
| NickB | SHIPPER | 08:27 |
| NickB | : JINAN G.WEIKE SCIENCE & TECHNOLOGY | 08:27 |
| mithro | yeah,that sounds like the same people | 08:27 |
| mithro | As I've read on the internet, the two following fees are a bit of a killer :( | 08:28 |
| mithro | Port Services Charge 720.00 AUD | 08:28 |
| mithro | Terminal Handling Charge 210.00 AUD | 08:28 |
| NickB | Well, nice to get a breakdown. Not toooo bad on $4000-$11000 worth of gear. I guess the $720+GST is the nominal "shipping" charge. | 08:31 |
| mithro | The "shipping" charge is actually probably like $200 | 08:35 |
| mithro | the Port Services Charge / Terminal Handling Charge is to get your stuff out of the port that it arrived in Australia | 08:36 |
| mithro | so I'm hoping that if they do door-to-door shipping that will be taken care for me | 08:36 |
| NickB | ahhh. So shipping is Origin CFS & THC | 08:36 |
| NickB | ? 240.00 USD | 08:37 |
| NickB | ? | 08:37 |
| mithro | NickB, yeah - that looks right | 08:37 |
| NickB | Origin Consignment For Shipping & Terminal Handling Charge, maybe? | 08:37 |
| NickB | I wonder if Fremantle port is any better or worse than Sydney... | 08:38 |

| mithro | the actual device is $2800 with bits, sea transport is $50, but then you end up with $700 in fees to get it out of the Sydney sea port | 12:15 |
| mithro | the sea port fees are pretty much the same despite the size of the item | 12:18 |
| thaytan | :-/ | 12:31 |
| mithro | just have to convince some friends to get one also at the same time :) | 12:33 |
