Invalid option "--buildinfo"
oiiotool -- simple image processing operations
OpenImageIO 2.3.10 http://www.openimageio.org
Usage: oiiotool [filename|command]...
Important usage tips:
* The oiiotool command line is processed in order, LEFT to RIGHT.
* The command line consists of image NAMES ('image.tif') and COMMANDS ('--over'). Commands start with dashes (one or two dashes are equivalent). Some commands have required arguments which must follow on the command line. For example, the '-o' command is
followed by a filename.
* oiiotool is STACK-based: naming an image pushes it on the stack, and most commands pop the top image (or sometimes more than one image), perform a calculation, and push the result image back on the stack. For example, the '--over' command pops the top two
images off the stack, composites them, then pushes the result back onto the stack.
* Some commands allow one or more optional MODIFIERS in the form 'name=value', which are appended directly to the command itself (no spaces), separated by colons ':'. For example,
oiiotool in.tif --text:x=100:y=200:color=1,0,0 "Hello" -o out.tif
* Using numerical wildcards will run the whole command line on each of several sequentially-named files, for example:
oiiotool fg.#.tif bg.#.tif -over -o comp.#.tif
See the manual for info about subranges, number of digits, etc.
* Command line arguments containing substrings enclosed in braces {} are replaced by evaluating their contents as expressions. Simple math is allowed as well as retrieving metadata such as {TOP.'foo:bar'}, {IMG[0].filename}, or {FRAME_NUMBER/24.0}.

OpenImageIO 2.4.6.0 http://www.openimageio.org

Usage: oiiotool [filename|command]...

Important usage tips:
  * The oiiotool command line is processed in order, LEFT to RIGHT.
  * The command line consists of image NAMES ('image.tif') and COMMANDS ('--over'). Commands start with dashes
    (one or two dashes are equivalent). Some commands have required arguments which must follow on the command line.
    For example, the '-o' command is followed by a filename.
  * oiiotool is STACK-based: naming an image pushes it on the stack, and most commands pop the top image (or
    sometimes more than one image), perform a calculation, and push the result image back on the stack. For example,
    the '--over' command pops the top two images off the stack, composites them, then pushes the result back onto the
    stack.
  * Some commands allow one or more optional MODIFIERS in the form 'name=value', which are appended directly to
    the command itself (no spaces), separated by colons ':'. For example,
       oiiotool in.tif --text:x=100:y=200:color=1,0,0 "Hello" -o out.tif
  * Using numerical wildcards will run the whole command line on each of several sequentially-named files, for
    example:
       oiiotool fg.#.tif bg.#.tif -over -o comp.#.tif
    See the manual for info about subranges, number of digits, etc.
  * Command line arguments containing substrings enclosed in braces {} are replaced by evaluating their contents
    as expressions. Simple math is allowed as well as retrieving metadata such as {TOP.'foo:bar'}, {IMG[0].filename},
    or {FRAME_NUMBER/24.0}.

Got asked about whether adding tbb support would make a difference on my slow dual xeon machine:

Years ago I noticed OIIO’s parallel scheduling code had a bunch of overhead. I vaguely recall lots of work being done to schedule out each individual pixel. Assuming I am not misremembering, and I might be, I am not surprised you are not seeing a scaling benefit, especially on multiple sockets where there is a large cost in cache line sharing. I’m curious if rebuilding with TBB support improves performance?

My response:

So, I've been testing some build variants.

When enabling more hardware features like SSSE3, SSE4.1 SSE4.2, AVX etc. makes it so that the executable doesn't work on my machine - likely due to some AVX (it does work on newer machines but there was no real measurable performance difference on this simple read/write test cases) so I opted going back to just the sse2 default but adding OpenTBB which does run.

Here is the output from using that build:
