| _florent_ | rohitksingh-demo: done, thanks | 03:08 |
| thaytan | CarlFK, for "gst file sink save chunky things" - what do you need? | 03:13 |
| thaytan | what are you writing to disk, how do you need it cut? | 03:13 |
| CarlFK[m] | thaytan: a process connects to vocto-core, gets a stream of the mixed video (and audio), does a light weight encode and saves to disk all day long.... | 03:16 |
| CarlFK[m] | thaytan: 1 big 8 hour 16 gig file is 'yucky' so we use ffmpeg to break it into 5 gig 30min files | 03:17 |
| thaytan | what are the formats along the way? | 03:18 |
| CarlFK[m] | thaytan: doesn't really matter - something "light" - low cpu and something melt/ffmpeg can decode as part of the final encode step that uses melt/xml cut list... | 03:30 |
| CarlFK[m] | which is about anything | 03:30 |
| CarlFK[m] | thaytan: here is what we are currently using: https://github.com/CarlFK/voctomix-outcasts/blob/master/record-timestamp.sh | 03:32 |
| tpb | Title: voctomix-outcasts/record-timestamp.sh at master · CarlFK/voctomix-outcasts · GitHub (at github.com) | 03:32 |
| CarlFK[m] | which sometimes stops. not crash, not exit, just ... stops. so we try have a watch dog that tries to detect this and kill it so that it isn't stuck. | 03:32 |
| CarlFK[m] | thaytan: this may already be implemented. I see code that might work. filesink location="$dest_dir/$(date +%H_%M_%S).gs.ts" | 03:43 |
| CarlFK[m] | https://github.com/CarlFK/voctomix-outcasts/blob/master/record-mixed-av.sh | 03:43 |
| tpb | Title: voctomix-outcasts/record-mixed-av.sh at master · CarlFK/voctomix-outcasts · GitHub (at github.com) | 03:43 |
| CarlFK[m] | er, no. never mind. | 03:43 |
| CarlFK[m] | it doesn't chunk. and stop/looping after 3600 * fps would lose a bunch of frames | 03:45 |
| thaytan | CarlFK, what's it receiving in that script? | 03:45 |
| thaytan | It looks like it's encoding to MPEG2? | 03:46 |
| thaytan | a couple of years ago, I wrote the splitmuxsink element for this purpose | 03:46 |
| thaytan | so you'll want to use that, and you could just remux and not reencode at all probably | 03:46 |
| xfxf | I'm for the above, remixing/reencapsulting sounds way more sane | 03:47 |
| xfxf | I think there's a missing feature in the splitmuxsink element tho, I have tried it | 03:47 |
| xfxf | I don't recall what it waa | 03:47 |
| xfxf | I can poke later, I prob still have the script | 03:47 |
| CarlFK | thaytan: 'raw' or however you would describe gst internal? format | 03:48 |
| xfxf | remuxing* | 03:48 |
| CarlFK | here is a 'simple' vocto source https://github.com/CarlFK/voctomix-outcasts/blob/master/tests/mock-stack.sh#L11-L19 videotestsrc name=videosrc ... matroskamux streamable=true name=mux ! tcpclientsink | 03:51 |
| tpb | Title: voctomix-outcasts/mock-stack.sh at master · CarlFK/voctomix-outcasts · GitHub (at github.com) | 03:51 |
| * CarlFK adds a 3rd item to thaytan's todo list... | 03:51 | |
| CarlFK | make that work more like vocto core | 03:53 |
| tumbleweed | _florent_: we've got an atlys up in the AV room, if you want to come and look at it | 05:17 |

| thaytan | CarlFK, what does "more like vocto core" mean? | 23:51 |
| CarlFK | thaytan: so... when i'm debugging vocto things, and I want to post a 'bug report' like thing (that may or may not be a bug) I would like a way to swap the vocto-core bit for something simple | 23:55 |
| CarlFK | no mixing, no switching, no all the things | 23:57 |
