CarlFKthaytan: 2 gsts.  1) vocto bug file handles  2) gst file sink save chunky things. we need.  it.02:39
rohitksingh-demo_florent_: Please check mail03:02

_florent_rohitksingh-demo: done, thanks03:08
thaytanCarlFK, for "gst file sink save chunky things" - what do you need?03:13
thaytanwhat 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 files03:17
thaytanwhat 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 anything03:30
CarlFK[m]thaytan: here is what we are currently using:
tpbTitle: voctomix-outcasts/ at master · CarlFK/voctomix-outcasts · GitHub (at
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
tpbTitle: voctomix-outcasts/ at master · CarlFK/voctomix-outcasts · GitHub (at
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 frames03:45
thaytanCarlFK, what's it receiving in that script?03:45
thaytanIt looks like it's encoding to MPEG2?03:46
thaytana couple of years ago, I wrote the splitmuxsink element for this purpose03:46
thaytanso you'll want to use that, and you could just remux and not reencode at all probably03:46
xfxfI'm for the above, remixing/reencapsulting sounds way more sane03:47
xfxfI think there's a missing feature in the splitmuxsink element tho, I have tried it03:47
xfxfI don't recall what it waa03:47
xfxfI can poke later, I prob still have the script03:47
CarlFKthaytan: 'raw' or however you would describe gst internal? format03:48
CarlFKhere is a 'simple' vocto source   videotestsrc name=videosrc ...   matroskamux streamable=true name=mux !   tcpclientsink03:51
tpbTitle: voctomix-outcasts/ at master · CarlFK/voctomix-outcasts · GitHub (at
* CarlFK adds a 3rd item to thaytan's todo list...03:51
CarlFKmake that work more like vocto core03:53
tumbleweed_florent_: we've got an atlys up in the AV room, if you want to come and look at it05:17

felix_i had a look at the exar driver and i'd say that it can't be upstreamed in its current state06:30

thaytanCarlFK, what does "more like vocto core" mean?23:51
CarlFKthaytan: 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 simple23:55
CarlFKno mixing, no switching, no all the things23:57
