New video codecs: new sounds great, new takes years.

If you are a video algorithm engineer, it’s likely that you spent years at university studying something abstruse in mathematics or particle physics. Or, perhaps, visual/mechanical reproduction systems.

When you take a commercial job working for a video encoding company, I enjoy reading your patent applications. I like seeing your standards-body submissions. It’s great seeing your names in the minutes-of-meeting for boards and committees. Sometimes, I get to meet you and shake your hand.

It’s even better when your submissions for a new video codec are not only accepted, but when they are endorsed and your peers start using the reference encoder components, the reference decoders, and when everyone uses the same videos to test compliance.

What’s hard is that this all takes years. Years! IBCs and NABs come and go, MPEG committees meet and disband, and time passes.

The result?

A provable, reference, standard for interoperability. And/or a set of parameters that others can go and innovate with. Products, systems, and even optimised circuits that map your math into personal enjoyment.

Codec is a portmanteau of coder-decoder or, less commonly, compressor-decompressor.

[ https://en.wikipedia.org/wiki/Codec ]

 

What hurts you, and the industry, is if someone decides there’s “a breakthrough” that is possibly based on a story.

Like, “Adams Platform“:

Investors who believed him ended up $27 million poorer. Despite the huge loss and the failure of the technology to work, no one has ever been prosecuted.

The Adams Platform technology could compress video by a ratio of a thousand to one, Mr Clark said. It could transmit full-screen, broadcast quality video over a standard phone line, he said. It couldn’t.

The claims seemed even more outrageous in the early 2000s, when broadband internet had yet to become the commonplace it is today. The potential seemed unlimited, and Mr Clark excited a huge amount of interest as well as a fair amount of scepticism.

It all amounted to nothing, and the company he floated on the ASX to exploit Adams Platform quickly folded after admitting there was no evidence the technology worked.

 

And like many others.

Now, if an amateur can download MediaInfo and look at a sample file that has been apparently encoded by a new codec, yet get all the encode parameters from the known codec x264:

x264 is a free software library for encoding video streams into the H.264/MPEG-4 AVC format.

……is it really new?

 

viz:

cabac=1 / ref=4 / deblock=1:-2:0 / analyse=0x3:0x133 / me=tesa / subme=11 / psy=1 / fade_compensate=0.00 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=24 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=0 / chroma_qp_offset=-2 / threads=7 / lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / fgo=0 / bframes=3 / b_pyramid=1 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / open_gop=0 / weightp=2 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=60 / rc=2pass / mbtree=1 / bitrate=1240 / ratetol=1.0 / qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / cplxblur=20.0 / qblur=0.5 / ip_ratio=1.40 / aq=1:1.00

 

And if the same amateur can view this video in a standard player, without any decoder component installed, is it really a new codec?

 

New sounds great: new takes years.

 

 

The Trout Fisher

“The Trout Fisher casts patiently all day. He frequently changes his venue and his lures. If he has frightened a fish he may ‘give the water a rest for half-an-hour,’ but his main endeavour, viz. to attract fish by something he sends out from his boat, is incessant.”

I be seeing you at IBC2014.

As some of us get ready for IBC2014, remember:

You will have scheduling issues, so be flexible.

If setting a meeting, or attending one, be considerate and try to keep in contact with each other.

You rarely need to see, or present, the first 6 slides of your deck.

The slides are there for cold prospects, not set meetings with your clients. Skip them.

You will walk circa 15,000 steps per day, so get your wearable/tracker ready.

Is this the most exercise you will get all week? Likely, sadly.

The WiFi will suck, your roaming won’t work or will be expensive, so get a MiFi and a local SIM.

It has always sucked, and will always suck, until a major serious vendor and sponsor get behind it.

You will run out of battery on your phone every lunchtime, so at least carry a cable so a kind soul like me with a 10,00mAh battery pack can charge you up.

And get your own battery pack. With two USB ports. Right now. Shipped to your hotel.

Get to bed before 2am. No meetings before 9am.

I’m not your dad, but surely this is common sense; aber IBC kommt nur einmal im Jahr….

Have enough time to just walk around, see new things, and meet new people.

I would never have met the university researchers working on vector-based video had I not bumped into their poster presentation.

The best networking, the best intel, the best gossip, and the best deals happen when you least expect them.

Go for that coffee. Or that beer, that glass of rosé in the afternoon sun. Go for a ride on a boat. Listen to what others see as the hot topics.

 

Your thoughts? Your tips?

 

 

LockTight – one more final update ;-) for Mac OS X Mavericks 10.9

Well, I managed to recompile it for 64-bit and for Mac OS X 10.9.

 

I can’t say that I can support it, or debug it, but if it works for you: fantastic!

 

LockTight for Intel (v0.1.2) (zip archive, 48kbyte file, HTTP download)

 

I’m referring to LockTight for your Intel-based Mac, per:
