| mithro | MaZderMind: we had a long discussion about syncing a/v from multiple clock sources at LCA | 00:08 |
|---|---|---|
| mithro | MaZderMind: basically we should be as good as DVSwitch which does nothing | 00:09 |
| mithro | MaZderMind: but in the future we will have the above syncing using gstreamer | 00:09 |
| techman83 | dvsource-alsa has a delay option that defaults to 200ms - but I don't know that dvswitch internally does anythin | 01:43 |
| techman83 | s/anythin/anything | 01:44 |
| CarlFK | techman83: that is because the cameras induce a bit of delay between audio in -> a2d -> firewire -> laptop -> dvswitch | 01:52 |
| CarlFK | that does not exist in audio -> laptop sound card a2d -> dvsiwtch | 01:52 |
| CarlFK | so the 200ms delay syncs alsa up with the video coming from a dv cam | 01:53 |
| techman83 | Cool | 01:53 |
| CarlFK | all of this is pretty irrelevant to mixy | 01:54 |

| MaZderMind | gst-switch is using intervideosink/src to cross the blocking-barrier and it seems that intervideosink/src is handling a/v-timestamps correctly -- in my tests a/v sync stays intact | 04:55 |
| MaZderMind | Hmmm… I have heretical thoughts. I'm really thinking if it is required to have the Server written in C, in the end it's just sticking pipelines together like this: https://github.com/voc/voctomix/blob/master/voctocore/experiments/intervideo.py | 04:57 |
| tpb | Title: voctomix/intervideo.py at master · voc/voctomix · GitHub (at github.com) | 04:57 |
| MaZderMind | all the high performance stuff is happening inside gstreamer | 04:57 |
| mithro | MaZderMind: there are a couple of places where we do want high performance - and that is mainly around changing the pipelines | 05:24 |
| mithro | MaZderMind: the GIL can also cause problems here too | 05:28 |

| MaZderMind | mithro: there shouldn't be much restructuring required. when a video-source connects for the first time is the only reason I can think of - and that would just allocate a new mixerpad and attach a intervideosrc to it | 05:36 |
| MaZderMind | mithro: on the other hand it would give you … readable code | 05:36 |
| mithro | MaZderMind: you can write unreadable code in Python :) | 05:36 |
| MaZderMind | *I* can't ;) | 05:38 |
| mithro | MaZderMind: well, once the UI is finished - maybe we can consider rewriting the server in Python | 05:41 |
| mithro | MaZderMind: the API is pretty simple, so it shouldn't be to hard | 05:46 |
