Getting Theora competitive

[lych_necross]

I prefer the pre-surgery Steve Jobs. He seemed less trollish before he got sick. Here's what Monty Montgomery said in response:

"Thomson Multimedia made their first veiled patent threats against Vorbis almost ten years ago. MPEG-LA has been rumbling for the past few years. Maybe this time it will actually come to something, but it hasn't yet. I'll get worried when the lawyers advise me to; i.e., not yet.

The MPEG-LA has insinuated for some time that it is impossible to build any video codec without infringing on at least some of their patents. That is, they assert they have a monopoly on all digital video compression technology, period, and it is illegal to even attempt to compete with them. Of course, they've been careful not to say quite exactly that.

If Jobs's email is genuine, this is a powerful public gaffe ('All video codecs are covered by patents.') He'd be confirming MPEG's assertion in plain language anyone can understand. It would only strengthen the pushback against software patents and add to Apple's increasing PR mess. Macbooks and iPads may be pretty sweet, but creative individuals don't really like to give their business to jackbooted thugs."

Theora (Ptalarbvorm) Demo 9 is out!

I still can't get over the fact that Ptalarbvorm was selected from a list of sarcastic joke names made up by a random Redditor :eek:

The following is even worse:
Ptalarbvorm' [Tall' - ar - vorm] (the P is silent, the b is optional)

I will keep pronouncing both the P and the b in the word "Ptalarbvorm", period. :devil:

P.S.: And more importantly,

Well Someone could just Fork the code an market it with some proper brand name. God knows how they continue to come up with all these AWFUL names........

Anyway.... Theora looking good? I cant believe i am saying this, it is a really great looking improvement finally.

The only problem is? Development is slow, It was nearly a year since last update, and properly take another year to get 1.2 shipped...

I don't think so... Probably in something like 2 or 3 months we will see a first Ptalarbvorm alpha out and in something like 5 months, oficial 1.2 version could come out...

At the end of the last demo (9), there's already some very early discussion about the next iteration 1.3 codenamed Eyjafjallajökull ...err... Volcano... So I think final 1.2 is not too far away.

Apropos Steve Jobs trying to keep the iPad "clean of p*rn" and "clean of Flash" -- now YouP*rn supports HTML 5. Go figure.

I still have my doubts about how absolutely necessary b-frames are. I think video codecs are just lacking the tools to do pure forward coding right ... we need a forward only direct mode for forward coding with multiple references for instance (which extrapolates motion, like it now interpolates it for the bidirectional mode).

no b-frame because it is still iffy about the patent issues, so On2 tried to avoid that

A first look at the development build of Ptalarbvorm for general users... Grab your ffmpeg2theora-Ptalarbvorm binaries...

http://lists.xiph.org/pipermail/theora-dev/2010-June/004164.html

Enjoy... I know I will :).

Yeah!, about time! :devil:

P.S.: :thanks:

[nakTT]

is it competitive now?

[tuqueque]

nakTT, that's really hard to answer... Maybe for someone it is and 5 minutes later, someone else will reply saying that is crap...

I will try to give an impartial answer though... For the test I made, quality wasn't as better as I expected... There was some improvement, especially on the "dirty window" problem fixed by a better SKIP behavior (check http://people.xiph.org/~xiphmont/demo/theora/demo9.html for more info)...

I'm still waiting for a couple of improvements on this Ptalarbvorm cycle (Temporal RDO and relative chroma resolution at low bitrates) before making a final judgment... So far, is better, but not as good as I frankly expected... But There's room for improvement so I don't rush.

[Midzuki]

Well, the very first builds of the "ptalarbvorm-ed" :devil: ffmpeg2theora did include a usage-message, such as:

ffmpeg2theora 0.27 - Xiph.Org libtheora 1.2.0alpha 20100924 (Ptalarbvorm)

Usage: ffmpeg2theora [options] input

General output options:

etc etc etc

Now, the latest nightly builds from firefogg.org show only this:


[C:\downloads]
=>ffmpeg2theora

:mad: :mad: :mad:

P.S.:

firefogg.org/make/index.html says:

Please first install latest Firefox. Then revisit this page to install the Firefogg extension.

Me, install Firefox ?

Skrew them !! :p :D

Anyone know how good is theora right now? Any major update?

[Dark Shikari]

There hasn't been much work on Theora in the past year because most of those involved have been quite busy with the standardization and finishing of Opus (Celt+SILK combination).
