MS-For those curious, I've transcoded and uploaded the tutorials, and when blip's converted them to flash there's a visible loss of a/v sync20:23
MS-As a result, I'm currently investigating that - my suspicion is ffmpeg doesn't do what it should - so retrying a test with a different encoder20:24
_dboddieMS-: I assume that you don't see the problem with a non-Flash encoding.20:25
MS-I don't see the problem with ffplay - so when I tested with that it played fine20:26
MS-Though when I play the ffmpeg encoded video with mplayer, there is the same desync - hence why I'm suspecting ffmpeg20:26
_dboddieDoes ffplay play Flash files?20:29
* _dboddie is confused.20:30
MS-The files I have are 4GB per hour. blip.tv has an upload limit of 1GB per file. So I'm transcoding down to about 1.8Mbit/s video before uploading that to blip.tv20:30
MS-blip.tv then transcodes that to flv for browser playback, but allows you download the originally uploaded file20:31
MS-blip's conversion to flv loses a/v sync, so hunting what's causing that20:31
MS-My conversion of 4GB/hour - 1.8Mbit/s was done using ffmpeg, to mp4/aac, and plays back fine with ffplay20:32
_dboddieOK.20:32
MS-but after seeing these issues with blip wondered if the a/v stream created by ffmpeg was compliant20:32
MS-hence testing with mplayer20:32
_dboddieGood luck! I saw your blog post about your transcoding process - very interesting. :-)20:33
MS-which shows the same issue as blip, so that's why suspicious of stuff20:33
MS-Cheers :)20:33
MS-In terms of what I change, it'll be one line, but figuring out specifically whether it's worthwhile takes time :)20:33
MS-On the upside I appear to be able to transcode  ~ 32GB overnight, so that's a fair chunk20:34
MS-:)20:34

tobixenI lost my plane from London.  I'm stuck :(23:41
Nailorwhat? :P23:49
NailorStuck at aiport? Or in London?23:49
tobixenNo, in London.23:49
tobixenFirst the metro to London Bridge didn't work because someone had jumped into the rails or something ...23:49
tobixenthen I decided to go to Victoria and take Gatwick Express23:50
tobixenstanding at Victoria there were people everywhere and impossible to move23:50
Nailoroh23:50
tobixenthen they said over the loudspeakers, five minutes later, "everybody please evacuate the station due to an emergency situation"23:50
tobixenI tried to go to Kings Cross ... but only slow trains from there ... and the station is huge and it takes lots of time to find the way there ... so I had no chance23:51
NailorSorry to hear :+23:51
Nailor:\23:51
tobixenplane tomorrow is very expensive ... I hope my employer will pay, though ...23:52
NailorHave you checked other alternatives, like Ryanair from Standsted (which is bit further away from london though)23:54
tobixenStansted would be better for me ... staying at Tottenham Hale ;-)23:54
tobixenRyanair doesn't go to the main airport in Oslo, but to a very different airport, and I need transit from London23:55
tobixenfrom oslo23:55
NailorAh23:55
tobixenthere are direct planes to my hometown some few days a week with Norwegian ... so thats how I came to London23:55
tobixenI'm living quite far north.  The distance to Helsinki is shorter than the distance to Oslo, actually.23:57
