Using YouTube to Transcode Videos to DASH on the Command Line

by @edent | # # # # | 9 comments | Read ~1,081 times.

This is part of my redecentralisation efforts to liberate my videos from YouTube. MPEG-DASH is a simple method of streaming videos which doesn't require any specialised server software. You convert a high resolution video into a series of smaller resolution videos. You chop each of the videos up into several chunks. As the video plays,… Continue reading →

Add date metadata to MP4 videos

As ever, notes to myself. I hope you appreciate this future me! Photographs often contain EXIF metadata - really useful for finding out when a photo was taken. It turns out that you can add similar metadata to MP4 format videos. Here's how to do it with ffmpeg on Ubuntu Linux. The magic option is… Continue reading →

Experiments Using (not quite) Google Glass

Way back in 2010, I got a pair of video recording sunglasses. I've been occasionally using them to "lifelog" what I'm doing. With the advent of Google's Project Glass, I thought it would be interesting to wear them to a fairly techy event - Not At SXSW London - to see what the reaction would… Continue reading →

Beautiful video about the work Derby Museum has been doing with Wikipedia & QRpedia. Derby Museum using multilingual QR codes from Andrew James Sykes on Vimeo.

QRpedia Presentation at Derby Museum

It's always an odd experience to watch yourself speak. Everyone - I think - finds the sound of their own voice really odd. I'm no exception! This is the video from the Derby Museum Backstage Pass where we gave the first public demonstration of QRpedia. The Video Video shot by Nick Moyes. The Slides All… Continue reading →

Oh! Woe is me! I can't make BarCampLondon 8. This will be the first BarCamp I've not been able to get to in ages. Following hashtags is fun, if a little disjointed. What I really need is some way I could attend virtually..... @barcamplondon idea for you: film all sessions & stick them on archive.org… Continue reading →

Video Sunglasses - Further Details

by @edent | # # # # # # #

A few updates on the Video Recording Sunglasses I blogged about earlier in the week. I stuck in an 8GB microSD card and let the glasses record indefinitely. I was curious what would happen when the size of the video went over the 4GB limit imposed by FAT32 - and what happened when the memory… Continue reading →

A Glimpse Into The Future

My eye has been caught by a stunning new gadget - the Immortal Video Eye Gear. Head mounted 3-megapixel video camera.  Seamlessly embedded within a pair of innocuous looking sun glasses.  At £250, they're not cheap.  While battery life looks good at 2.5 hours, they can only record one hour of video. No method of… Continue reading →

BarCampBrighton4 and High Def Video

by @edent | # # # # # #

Another weekend, another BarCamp.  This time the Fourth Annual BarCampBrighton. The BarCamp was excellent.  A great bunch of people.  The venue was beautiful, but the lack of walls (and floorboards!) meant that sound bleed was a problem. The problem I have with BarCamps is there are invariably two or three talks which I really want… Continue reading →
