However, in the early days, when bandwidth was narrow, video was small, and not many of us actually played with it online, QuickTime had this thing called a reference movie (which was not the same as the reference movie option you get when saving a QuickTime file in QuickTime) which was a tiny little place holder video you created. … This is going back to the future because a series of steps and constraints have been reintroduced: if you want to send video or audio that is over 10 minutes in length over a mobile network (NOT WIFI) to an iOS device then you just have to use HTTP live streaming (this is the overview page ) If that isn’t enough then you must include a low bit rate version with a max data rate of 64 Kbps that it can default to when you hit that service shadow you need to run your compressed video through some other tools to get it ready for Live Streaming – this includes the Media Stream Segmenter, the Media File Segmenter, and the Media Stream Validator But it is ambiguous in the documentation if you have to do this, or it is recommended – essentially the protocol lets the client jump from different versions as it plays.
Nice YouTube clip outlining YouTubes terms of service in plain English. It has been made by an undergraduate student in Western Australia.

They don’t support RTSP. (I assume because it is a protocol that provides… Read more →

Why such a large file? Because it is an… Read more →
Quick informal testing when viewing a YouTube clip you can’t scrub anywhere in the timeline and expect the video to stop what it is doing and go grab the data needed to start playing from that point, you have to wait for it to arrive however, you can put a start time in a url for a YouTube clip (what YouTube call ‘ deep links ‘), trying to test this, so this URL is for a 8′ 45″ clip where I have included a deep link to 8 minutes in. http://youtu.be/UUplAPmV61I? #t=8m Not sure how to test this properly, but if it plays immediately then it is a far bet that it has started at 8 minutes without needing to buffer the first 8 minutes of video…. perhaps should also try this with either some HD content, or a really long file (eg something over 30 minutes long) would appear that YouTube’s deep links provide a beginning time, but not an end time Outcome, well right now I can’t even get the above deep link to work, it just defaults to the beginning of the clip!
This will be delivered via http to see that it does stream without packet loss see what sort of quality it produces see what devices it actually plays back on The second experiment is going to use a data rate that should work for an iPad and higher, but compressed with a hint track so that it can be delivered via RTSP. This I will serve via my dreamhost account to: see that it does stream without packet loss see what sort of quality it produces see what devices it actually plays back on Experiment two video settings: Experiment two video size settings: Experiment two audio settings:

In no small measure due to the timely arrival of our new Computer Science PhD candidate Lukman Iwan, over the last week or so we have been making further progress towards our first prototype. As the Living Archive will have not just Oz videos, but also information about them, one of our first tasks is to gather and organise the… Read more →
It turns out there is no extant taxonomy for circus performance (it is not my area at all so I don’t even know if such a thing exists formally anywhere in the performing arts), and so we have started to make one. … Then we worked through what this meant, which was that this was an expert taxonomy and not really how you and I would begin to find a particular act in an archive of circus performance (after all, until I visited Wikipedia, I had no idea what ” tissu ” was in circus).
