DebConf10 post-production

credits and sponsors append or prepend to transcodings

• valession has made some intro and outros, we should attach them to the videos
• credits needs finalisation: http://whiteboard.debian.net/dc10credits.wb

19:48 < edrz> istr there being issues with most clients handling chained theora streams properly.
19:49 < gmaxwell> edrz: if you have/know the encoder that produced the file you can encode the credits with the same settings and then oggCat the results.
19:50 < edrz> and that handles the serial numbers and granulepos or whatever correctly?
19:50 < gmaxwell> Maybe.
19:50 < gmaxwell> It's supposed to do what you want, but it may be buggy.
19:51 < derf> oggCat must also be linked against the exact library used to create the videos.
19:51 < derf> Because it doesn't actually look at them for configuration, AFAICT.
19:51 < edrz> oggCat is in what tool set?
19:51 < gmaxwell> oggvideotools
19:51 < derf> There's library support for doing things correctly since https://trac.xiph.org/changeset/17333, but no actual tools that use it yet.
19:51 < edrz> i can easily build .debs against the same libtheora & ffmpeg and use the same ff2th.
19:53 < edrz> ok. so it should be doable.
19:53 < edrz> but might take a little doing.
19:54 < gmaxwell> In the case where you created both videos it's trivial!

• Valessio also answered my question how easy it is to modify the credits: "Is possible and very simple. It is an image created with Inkscape. 700px X 5000px or more... and synfig render movie. all source: http://valessiobrito.info/projetos/debconf/debconf10/credits/ I can apply changes, send-me model plain text."

events with specific problems

• see DebConf10/Videoteam/ReportBug

fixing audio samplerate issues

Some files from the first days may have too fast audio playback due to wrong sample rate from the audio device(s):

20:43 < bwh> edrz: Try ffmpeg -r 330750:12012 -ar 44100 -i broken.dv -target ntsc-dv fixed.dv

encoding marga's opening .avi

it's in /home/marga

20:27 < bwh> edrz: If you run 'dc-do-transcoding --dry-run | less' on barney that will show you the command lines we use

organizational stuff

• update Hardware page w/current locations and components
• edrz took most stuff home to && inventory && sort out best shipping destination & method
• collect, colate and analyze stream stats
• ditto for file downloads.

General ToDo, for next years

Penta bugs / issues / wishlist

• auto expiry of reviewing claims
• multiple persons sometimes get signed up for same room role
• view with assigned volunteers

information wrangling

• Clean up wiki
  • copy/edit/revise relevant pages -> DC11
    • streaming set up
    • hardware
    • audio mixers
• improve diagrams
• create room diagrams with audio cables
• final report
• back up wiki
• training materials
• document:
  • DC10 successes
  • problems
  • room for improvement
  • intended features not implemented.

software / configs / data / howtos

• Streaming stuff
  • create a nicer splash page or something than the icecast default (xslt stuff, maybe .. edrz rediscoverd an example)
  • ask for source and documentation for valessio's loops and stream landing page
  • settup replay mount with ezstream test streams of playlist from past (apu and lisa, or maybe only lisa this year.)
  • test encoder settings
  • Maybe try 2 encodings if we have time and cpu? (edrz dreams ...)
• VP8 encoding: penta db change, encoder tool and settings, debconf-video script changes
• dirac?

Shopping list

• 2nd larger audio mixer
• DI boxes

Ideas for the future

• use functional hostname rather than simpsons character names
• prevent fsck on boot
