The market isn't a person.
They don't do anything productive on there. Try using a spreadsheet program on a phone.
Do I look like a Youtube datacenter?
We are far away from the point where we have the most efficient solution.
Half truth. Depending on the content there is lots of artifacts that can simply be compressed away (H264 hi10p and anime) and as above:
Current solutions are very rudimentary and only describe pixel changes and left right up down movements.
If something on the screen rotates it can't be well compressed.
There are many other common things to compress but that one alone should suffice.
You can't make any fundamental changes to them. Only slight improvements can be added on.
Video codec wars

For several reasons. First and foremost the codecs that were popular in the past were patent encumbered which means NDA's and huge costs to get the copy+pastable library. Secondly because GPU's are essentially a CPU of varying artchitectures heavily optimized for much fewer commands, a reduced instruction set if you will. So the codec library must be implemented with either special instructions in hardware or by having access to the ISA of the GPU. The problem with this is unless you are talking about ancient GPU's or nvidia gpu's on nouveau prior to the 900 GTX series no one gets access to the GPU's ISA. Except via intermeditary layers that are blobs loaded at runtime such as AMD's microcode or nvidia's signed firmware. So implementing the newer codecs requires knowledge few but the NDA signers have, which work for the companies, who get kickbacks from codec producers who they already implemented for not to implement newer codecs.
Say you wanted MP4 acceleration on a GPU, you just implement it at the ISA level just like a modern CPU via a library calling instructions. But you have to be able to program those instructions which most modern GPU's will not let you do.
Third the patent encumbered codecs want to stranglehold the industry in order to get more liscensing shekels. Jewgle allows vp8/9 only because it benefits them so much in electricity costs saved for youtube streaming and bandwidth costs.
The only way out of this mess is someone developing a codec that uses the best of the best of the algorithms, including the patent encumbered ones, and just making the best software possible for implementation. Then publishing and updating a implementation anonymously using p2p software so that patent trolls can't fuck them over with cease and dissists. Then on the GPU's with access to the ISA of said GPU's GPGPU offload could be implemented.
But few have knowledge of the codecs to make a better codec. Even fewer would know how to upload a thing without getting a cease and dissist. Much much less fewer then that would have the knowledge to implement GPGPU offload, and the few that do already are in the hands of corperations or are blackmailed into doing nothing and or are too busy with irl survival.

Case and point to my post, see a user like this that understands why a encoder/decoder needs to do what it does and who doesn't give a shit about copyright. He could implement a codec maybe and upload it anonymously because scenefag but then has none to little knowledge about gpgpu stuff.
Lincoln Green
I understand as much about gpgpu as publicly available. As you said user the problem lies in the fact that modern GPUs are so locked down. It's impossible to learn when you can't even make them say Hello World.
