A Blog Reborn

March 27, 2011 Leave a comment

When I orginally started this blog back at the beginning of 2008, it was dedicated specifically to open source video topics. This was something I was passionate about and involved in. Over the last three years much has changed, although I am still deeply interested in open source video.

Over time I found that I wanted to blog about other topics, but didn’t really have an outlet for this. I didn’t want another blog.

My work circumstances also changed. After eight years at BBC Worldwide, most recently as Head of Digital Distribution, it was time for a change. I invested in a small post-production company in central London, The Station, and also started consulting for mediapeers, a specialist broadcast content distribution tool vendor.

I was also paying too much money each month for a dedicated server that I wasn’t really using. This blog has now moved to WordPress’ own hosting solution.

There it is, a new start and a fresh approach. I sincerely hope there will be a steadier stream of content on this blog, from a wider range of topics.

FFmpeg: Update Installing on Ubuntu Hardy

May 1, 2008 1 comment

Having recently installed Xubuntu Hardy Heron on a laptop, I also
needed to install FFmpeg. This post is really just a couple of notes
for myself, updating my earlier How-To post regarding installation of
FFmpeg on Ubuntu Gutsy.

New apt-get install line:

sudo apt-get install liblame-dev libfaad2-dev libfaac-dev
libxvidcore4-dev liba52-0.7.4 liba52-0.7.4-dev libx264-dev libdts-dev
libswscale-dev checkinstall build-essential subversion

Here I’ve added the swscale development libraries. Swscale is used for scaling videos.

If
you are ever stuck behind a firewall or proxy, especially one that you
have no control over and which does not understand certain SVN
commands, there is a nightly Subversion snapshot available for download
from the FFmpeg website. This alleviates the need to checkout the
source with SVN.

New configure line:

./configure
–enable-gpl –enable-libvorbis –enable-libtheora –enable-liba52
–enable-libdc1394 –enable-libgsm –enable-libmp3lame –enable-libfaad
–enable-libfaac –enable-libxvid –enable-pthreads –enable-libx264
–enable-shared –enable-swscale –enable-avfilter –enable-postproc
–enable-avfilter-lavf

Here I’ve removed –enable-pp as it is no longer recognised. And I’ve
added –enable-swscale, –enable-avfilter, –enable-avfilter-lavf and
–enable-postproc

Avfilter is the new FFmpeg library that replaces the deprecated vhook functionality.

One last note to self is to investigate the possibilities of AVIsynth scripting and FFmpeg.
