Yet another x265 HEVC encoder

[Kurtnoise]

I found this (https://github.com/lheric/x265) today on github...It looks completely different from the Multicoreware one and it's written in plain C. :cool:


A windows build is available here (https://www.mediafire.com/?4kcziqf43au3jf8) for testing.

[Kurtnoise]

265 core:1r1.0
Syntax: x265 [options] -o outfile infile

Infile should be raw (in which case resolution is required).
Outfile type is selected by filename:
.bin -> Raw bytestream

Options:

-h, help List all options
-c Configuration file name

[Procrastinating]

I have a feeling that there's going to be 5 variations of x265, and they are all going to race to become the best x265.

[DarrellS]

No stdin = useless for me if I can't use with Virtualdub's external encoder.

^ This. It's getting crazy

what do you mean by that ?

pipeline is supported as well...

[DarrellS]

I'll try again but I got an error that no input file could be found. Maybe you could supply a working command argument. Everything I tried resulted in one error or another.

They could easily accomplish that unifying the resources and efforts into one project that would move at lightspeed.
