@Lachlan, you're obviously being slightly short sighted in your view of video formats. H264 is becoming one the most mainstream codecs available, due to its high quality. FLV is closed source and to be honest, only really used on the web, therefore useless.

In the end ask yourself, why support a lot of formats badly rather support one format well?

Flv is the format all youtube videos are in. I have about 100+ .flv youtube clips on my harddrive, and I'm sure there are other people out there who have done similarly, as the clips are quite easy to get. I didn't realise that it was closed source, but then again aren't most codecs/formats barring Xvid closed source? (this is a legit question- I'm genuinely usure of which video codecs are/aren't open sourced)

senab:
FLV actually uses the codec VP6, and afaik only a open source directshow decoder is available, and no encoder.

Open source Video formats include:
Xvid
Ogg Theora
x264
Dirac
VP3 (which Theora is loosely based on)

lachlan:
Those formats all seem relatively obscure (except Xvid). Is it due to them not being as good/efficient as other closed source formats, or is there a different reason?

Noxneo:
Ogg theora is very efficient, it's just that closed source formats are more popular, and therefore pretty much nobody know about those formats.

senab:
x264 is a H264 encoder. H264 is part of the Mpeg 4 standard (as is ASP, which xvid is an encoder of) therefore it's popular. H264 has been used recently as a HD format due to its excellent quality at small bitrates.

Dirac is an encoder being developed by the BBC for HD. See here: http://dirac.sourceforge.net/overview.html
