| tpb | mithro: konstovl was last seen in #timvideos 10 hours, 9 minutes, and 5 seconds ago: <konstovl> Hello | 01:01 |
| CarlFK | mithro: how does this look for an example of what is needed for streaming video over the lan: | 01:05 |
| CarlFK | source: gst-launch-1.0 -v videotestsrc is-live=true pattern=18 ! avenc_mjpeg ! rtpjpegpay ! udpsink | 01:05 |
| CarlFK | consumer: gst-launch-1.0 udpsrc caps="application/x-rtp" ! rtpjitterbuffer ! rtpjpegdepay ! avdec_mjpeg ! videoconvert ! videoscale ! autovideosink | 01:05 |
| mithro | CarlFK: What for? | 01:08 |
| CarlFK | hdmi over eathenet | 01:09 |
| thaytan | CarlFK, I'd add a queue after the decoder in the playback pipeline | 01:13 |
| CarlFK | thaytan: sure.. but why? | 01:14 |
| thaytan | and consider other encodings than mjpeg, which is cool and low latency, but pretty high bandwidth compared to x264enc tune=zerolatency | 01:14 |
| CarlFK | the encodeing side will be implemented in fpga | 01:14 |
| mithro | CarlFK: you don't really stream *to* the device at the moment | 01:14 |
| thaytan | CarlFK, because the video sink will always block until it's time to display the frame | 01:15 |
| thaytan | with a queue, your decoder can start on the next frame already | 01:15 |
| thaytan | gives you more headroom in case of hiccups (like someone else hogging cpu for a moment) | 01:15 |
| mithro | CarlFK: so you just need to receive from the FPGA board | 01:16 |
| CarlFK | mithro: I wanted both sides so that there is a reference for "works like this" | 01:16 |
| mithro | CarlFK: something like "gst-launch-1.0 udpsrc caps="application/x-rtp" ! queue ! rtpjitterbuffer ! rtpjpegdepay ! queue ! avdec_mjpeg ! videoconvert ! videoscale ! autovideosink" | 01:17 |
| mithro | CarlFK: I'm unsure if rtp is the right solution for the FPGA, but something like rtp should be used | 01:17 |
| CarlFK | yeah, I figure any gstreamer pipe is fine. | 01:18 |
| *** mproctor has quit IRC | 01:40 | |
| mithro | We do probably want to use UDP otherwise the FPGA code would get too complicated | 02:17 |
| mithro | CarlFK: I'll try and do some gst-switch clean up / fixing on the weekend | 02:18 |
| CarlFK | yay! | 02:26 |
| mithro | CarlFK: no guarantees, it's stuck behind a bunch of work I need to do for the HDMI2USB stuff | 02:32 |

| CarlFK | thaytan: do you do any gstreamer c coding? | 05:17 |

| thaytan | CarlFK, only since 2003 ;) | 05:32 |
| thaytan | o/ | 05:32 |
| CarlFK | heh.. if you will take a shot at porting it I'll test it (bringing up dvswitch isn't trivial, but I do have a Vagrantfile if you really want to) | 05:35 |
| thaytan | I'd have to learn what a Vagrantfile is :( | 05:42 |
| thaytan | on the upside, I can make Joelw teach me | 05:43 |

| tpb | Title: dvsmon/Vagrantfile at master · CarlFK/dvsmon · GitHub (at github.com) | 05:49 |
| CarlFK | vagrant will dl "http://files.vagrantup.com/precise64.box" bring it up in virtualbox, and run the script | 05:50 |
| CarlFK | then you can gst-plugins-dvswitch connect to port 2000 | 05:52 |
| CarlFK | both as a video source or sink | 05:52 |
| mithro | thaytan: I think you mean shenki? (Joel Stanley) | 06:11 |
| mithro | Unless you know joelw too? He is pretty cool too so I wouldn't be too surprised. :-) | 06:12 |
| mithro | Joelw: have you made it to an like Linux.conf.au before? I can't remember... | 06:13 |
| mithro | thaytan: micolous and xfxf are both good sources of information regarding dvswitch too (micolous wrote the initial gst-plugin-dvswitch which you extended) | 06:15 |
| mithro | Oh, still haven't got a laser cutter yet :-( | 06:15 |
| thaytan | mithro, no, I mean joelw :) | 06:17 |
| mithro | How do you know him? | 06:17 |
| thaytan | 6-degrees thing | 06:17 |
| mithro | I'm thinking we have had this conversation before.... | 06:18 |
| thaytan | not that I remember | 06:19 |

| xfxf | oh, what did you hack on? i always assumed it was flumotion | 09:08 |
| xfxf | hi, btw, long time no speak :) | 09:09 |
| thaytan | xfxf, GStreamer itself, DVD player | 09:20 |
| xfxf | ah, right. you probably have told me that before but my memory is awesome | 09:22 |
| xfxf | if i recall from fb, you're out in wodonga/albury these days? | 09:22 |
| thaytan | *nod* | 09:32 |
| xfxf | what landed you out there? | 10:31 |
| xfxf | should catch up for a beverage next time i'm driving between melb/syd :) | 10:31 |
| thaytan | xfxf, sure - we have spare beds too | 10:53 |
| thaytan | xfxf, a random throw of the dice, more or less | 10:53 |

| andi-m | or does somebody know the search terms for case? | 23:33 |
