dboddie_Hi pboddie.16:55
tobixenhow did you find the trakai castle?16:55
dboddie_tobixen: Picturesque. Have you seen the photos on Flickr?16:55
tobixenno.  I was quite disappointed that it wasn't possible to climb the towers16:56
dboddie_It would have been good to get higher than the main castle. :-)16:56
tobixenand disappointed that we didn't bring towels and bathing clothes ;-)16:56
dboddie_Indeed. :-)16:56
pboddiedboddie_: Hello!16:57
dboddie_tobixen: Are you back in Norway already?16:57
tobixenno, I'm in Tallinn now16:57
tobixenspent the weekend in Latvia16:57
pboddietobixen: You and your colleague seemed to disappear at the castle. I thought you'd discovered the secret level. ;-)16:58
* dboddie_ is surprised to see so many people on the channel.16:58
tobixenmaybe I'll be in Norway before the 30th of July ... if we won't go to Siberia.  There is a solar eclipse at the 1st of August :-)16:58
tobixenwe were just a bit in a hurry, so we ran through all of it ;-)16:58
pboddieMrTopf: Saw that you uploaded a video yesterday - quite a big file, too.17:03
MrTopfyes, unfortunately. Every lower setting looked bad unfortunately17:05
MrTopfthat's the joy of doing video17:05
MrTopfI was also redoing it today as I wanted to keep with episode number going17:06
pboddieThe picture quality looked OK from what I saw, but I didn't seem to get audio in VLC.17:06
pboddieThat may be something with my version of VLC, and GStreamer didn't want to transcode it, either. Maybe I don't have some MPEG 4 support installed.17:07
MrTopfblip.tv also has an option to convert it to ipod format17:07
MrTopfwhich might be smaller17:07
MrTopfand I just copied the audio, maybe I need to reencode it17:07
pboddieI just grabbed from the URL mentioned in the meta tag.17:07
MrTopfgood that I did not yet do all videos ;-)17:07
MrTopfI will look into that later and see if it works in smaller filesize17:08
MrTopfbasically I am now using keynote to encode it17:08
pboddieI think we all appreciate the work you've been doing with the videos.17:08
MrTopfas then I can directly put a title in front of it more easily17:08
MrTopfbut I don't have any video controls or transitions or video editing17:08
MrTopfand I spent the day yesterday trying to automate things with applescript17:08
MrTopfand now I know that applescript sucks ;-)17:09
MrTopfI now test different settings17:13
MrTopfand I noticed that the original audio is linear pcm which means big file size17:14
MrTopfso I now changed it to AAC and reencode it17:14
MrTopfI also put a nice europython logo in the lower right corner so that you never forget what you are watching ;-)17:14
MrTopflooking forward to 64 core machines to make video encoding faster17:16
dboddie_Maybe you need to look at using the Cloud. :-)17:18
pboddieI like the intro titles for the video: very nice!17:19
mgedminwhere could I find those videos?17:25
MrTopfdboddie_: I would if somebody would implement the service I need ;-)17:28
MrTopfI don't have time to do that myself right now ;-)17:28
MrTopfactually I just changed the intro to show the epside number, I also noticed that I already had an intro for CLTV so I am using this now but copied the flying titles in17:28
MrTopfmgedmin: comlounge.blip.tv I think should work17:29
MrTopfit's only one now anyway17:29
mgedminimpressive intro!17:33
* mgedmin cannot wait to finally see all of the Capistrano talk of which he only saw the very end17:33
pboddieI think a few people started to see the benefits of talk recordings when they were heard to say, "I have to miss that one because I'm in another, but I'll see the video later."17:36

MrTopfnow if they would go out and search for a sponsor for next year... ;-)17:42
pboddieBMW? ;-)17:42
MrTopfjust tell them that we are the new TED17:43
MrTopfwe even had Rosling17:43
MrTopf;-)17:43
MrTopfsomebody ask Al Gore for next year17:43
dboddie_TED is so 2007. ;-)17:43
mgedminnah, TED is nice17:50
mgedminand an RSS feed with liks to TED videos is even nicer17:50
mgedminI can click on a title in Banshee and start watching it17:50
MrTopf*uploading slides* finally17:52
mgedminthe "how to upload slides" lightning talk was a nice fail17:54
pboddieWell, there was a step #0 in the process which was demonstrated.17:54
MrTopfI use slideshare anyway17:56
MrTopfhere is the first:_ http://www.slideshare.net/mrtopf/europython-2008-dataportability-and-python18:01
*** sverrej has joined #europython18:08
pboddieMrTopf: How about linking them from the Talks/Themes Wiki page?18:10
MrTopfThat's the plan18:10
MrTopfI just wanted to upload all to do the linking in one go18:10
MrTopfmaybe also my not given lightning talk ;-)18:10
pboddieBonus material!18:11
MrTopfNext year we should do more lightning talks18:11
MrTopflike also on the first day18:12
MrTopfand the next one: http://www.slideshare.net/mrtopf/europython-2008-tear-down-the-walls-of-virtual-worlds/18:15
MrTopfpboddie: now I have 83 MB but you cannot read anything anymore18:22
MrTopfnext try with better settings18:23
pboddieI'm inclined to look at transcoding the original 200+ MB file if I can get the right libraries. I'll let you know how I get on.18:24
MrTopfI might upload the next try once it's finisged18:27
MrTopffinished even18:27
*** cyberix has quit IRC18:40
* pboddie thinks about ending the fairly unproductive day at work.18:55
*** sverrej has quit IRC19:03
MrTopfgreat, middle quality results in bigger file19:06
MrTopf552 MB19:06
pboddieI think I'll head home now, but I'll look at the original file and see whether there's any magic possible.19:07
MrTopfthere is but it needs some experimentation to find the right setting19:09
MrTopfI am not encoding smaller parts19:09
pboddieWell, I'll let you know what I discover, if anything.19:10
MrTopfok, thanks19:10
MrTopfnot sure though it will help that much as I am using a different tool and this usually also means different settings19:10
MrTopfbut mayby we can make it 2 passes then19:10
MrTopfalthough that seems to be somewhat more work19:11
pboddieWhat's the original format?19:11
MrTopfI am doing it with keynote19:14
MrTopfand exporting to quicktime with it19:14
MrTopftesting it now again with different settings19:18
MrTopfbut the problem is really that it will become more unreadable then. But there is not much to do with the light I had anyway19:18
pboddieOK. Will be back on IRC later on. Bye for now!19:18
*** pboddie has quit IRC19:19
*** menesis has quit IRC19:23
MrTopfone thing we should do is to work on chat so we can create an IRC gateway :)19:29
MrTopfwould be a good test of things19:29
MrTopfI guess this was the wrong channel ;-)19:31
tobixenbut it would be a nice thing anyway19:31
tobixenbitlbee is cool19:31
tobixenbut it's too unidirectional19:31
*** pedronis has quit IRC19:34
*** Sharebear has joined #europython19:55
Sharebearhttp://europython.org/UserPreferences - "Enter the name of a popular free software license"19:56
SharebearPerhaps a little ambiguous19:56
SharebearApache didn't work at least... I believe that one is quite popular19:56
Sharebear:-P19:56
dboddie_Sharebear: I'm sure someone will be along to assist at some point. :-)20:09
SharebearAaanyway, time for me to head home. Getting hungry now20:16
SharebearBut I got my slides up if anyone is interested http://my.opera.com/WebApplications/blog/2008/07/14/slides-from-europython0820:16

pboddieMrTopf: Hello again!21:21
pboddieI found out that I had to select track 2 in VLC to get the audio working.21:21
MrTopfinteresting21:21
MrTopfI will try another tool tomorrow21:21
MrTopfkeynote is not really doing it21:22
pboddieMeanwhile, I've been looking at GStreamer plugins and have installed the "bad" set from multiverse.21:24
pboddieIt appears that the normal Ubuntu "bad" plugins will make the qtdemux stuff available, but the multiverse "bad" plugins (ie. stuff which has sort of restricted stuff with respect to patents, I guess) are needed to actually provide the actual QuickTime/AAC support.21:25
*** marcink has joined #europython21:25
pboddieGStreamer doesn't want to do very much with the conversion pipeline, though.21:26
* dboddie_ gets ready to leave.21:26
TvAAC encoding is patent protected, yes.21:26
MrTopfI am actually not sure it's AAC in there but I haven't checked21:29
MrTopfit was set to pass audio through so I guess it's more or less PCM21:29
*** marcink has left #europython21:29
MrTopfwhich might be one reason for the bigger filesize21:29
*** mgedmin has quit IRC21:34
pboddieJust trying to manually coerce the conversion...21:43
pboddieInstalling gstreamer0.10-plugins-ffmpeg obviously helped, although it could have just said that it didn't understand the video format instead of "ERROR: pipeline doesn't want to preroll."21:58
pboddieThe audio didn't seem that great when I tried just now, but we shall see.21:59
*** menesis has joined #europython22:11
MrTopfmaybe just wait for tomorrow's version ;-)22:11
pboddieUp to 31 minutes so far. 50 MB of Ogg Theora.22:36
pboddieThis is just an exercise to see what's possible, of course.22:37
pboddieAt the default encoding, the talk is 71 MB, but the text on screen is unreadable. I also have to find out how to persuade the audio to run at the right rate.23:08
MrTopfI think it all would have been better with better light or actually less light in the room23:30
MrTopfor a better projector23:30
MrTopfbut anyway23:30
*** ccm|mac has quit IRC23:32
MrTopfI will now render just the intro from keynote, then take some video editor and do the rest there23:32
MrTopfmaybe that's better :)23:32
MrTopfI guess it's about using the right tools23:33
*** menesis has quit IRC23:48
MrTopfit comes down to that awful iMovie I guess23:50
