Theora 1.1 is out!

This should make Theora actually worth using, and that's great news for those of us who want to see Flash videos replaced with the <video> tag.

I wonder when we are going to see it in the repos.

Been testing it a bit. Quality per bitrate, it looks like it's still light years behind x264 :< Mind though, I don't know all the cool features of libtheora that might improve visual quality. Also, it's a let-down that is doesn't support multi-threaded encoding yet, as its performance is really poor compared to fully threaded 64-bit encoding of x264 on Core i7

I'm just going to stick with x264 myself, I love that particular codec. Hasn't let me down yet!

Ye, x264 is this the great king of H.264 encoding, and encoding overall. I really hope that theora will be a real competitor in the future though. For some things, I guess it is already. I'll try to embed the <video> tag in some of my web pages for shits and giggles though

EDIT: Been trying some low-bitrate theora anime (web streaming ). It's surprisingly good D: Very close to x264.

Not to bump this thread too much, but Chrome already has a FFmpeg plug-in to do this. So instead of having just one codec to work with, you get the the entire FFmpeg back end including Theora if you want it. I don't use Chrome, but now that it exists...

It's still better if theora gains popularity for web videos, it's good enough (for real hd, we need to wait for dirac), and can be supported out of the box on any browser.

The only problem is that there is no hardware-accelerated theora decoding yet...

Theora is never going to be the de facto standard for the web for a bunch of different reasons. And I doubt that dirac is going to gain much traction any time in the near future (or ever)*. There's a ton of weight behind H264/AAC right now, and currently it's the best lossy compression algorithm in wide spread use. The argument, as you pointed out, that theora is good enough for basic web stuff is true, but it can't do anything particularly unique.

* An interesting read on dirac/schroedinger from Dark Shikari (x264 and FFmpeg developer) can be found here:

You can get - along with other interesting stuff - in our adslgr64 repo.

I packaged it yesterday.

Here is our abs tree to see if anything else might interest you:

A slight modification of the official PKGBUILD works too:

pkgname=libtheora
pkgver=1.1.1
pkgrel=1
pkgdesc="An open video codec developed by the Xiph.org"
arch=('i686' 'x86_64')
depends=('libogg')
makedepends=('libvorbis')
url=http://www.xiph.org
license=('custom')
options=(!libtool)
source=(http://downloads.xiph.org/releases/theora/libtheora-${pkgver}.tar.bz2)
md5sums=('292ab65cedd5021d6b7ddd117e07cd8e')

build() {
  cd "${srcdir}/libtheora-${pkgver}"
  ./configure --prefix=/usr --enable-shared --disable-static || return 1
  make || return 1
  make DESTDIR="${pkgdir}" install || return 1
  
  install -m755 -d "${pkgdir}/usr/share/licenses/${pkgname}"
  install -m644 LICENSE COPYING "${pkgdir}/usr/share/licenses/${pkgname}/" || return 1
}

I believe that videos will first have to be encoded in 1.1 for this to work (correct me if I'm wrong). And Firefox won't be able to support it yet. See this link (bottom of comments). Just FYI.

Interesting. Both of the videos (1.0 and 1.1) linked to in the main article work fine for me with the FF from the repos. I guess that I'm missing something.

--EDIT--

Yeah, I'm missing something. Between the time that I posted the PKGBUILD and tested this, I removed libtheora. In fact, I don't have any codec from Xiph installed on this machine. I'm not sure exactly how I'm getting video playback, but I am.
