589d38971f Texture video changes 2019-06-07 20:47:21 -07:00
richgel999
ab722fa2e1 - Adding support for skip blocks, i-frames and p-frames to the backend and transcoder, for texture video use. 
- For PVRTC1, we now memset() any extra blocks after the blocks we know will be transcoded into. This is done because in GL there is padding that occurs on textures smaller than 8x8.
- Removing all OpenMP usage and replacing it with a basis C++11 job system.
- Fixing TSVQ class so it can split very long "thin" clusters that before weren't being split. This improves endpoint quantization on videos and complex 2D textures.
- More frontend perf. optimizations.

Tested on OSX, Linux with gcc/clang, and Win using MSVC 2019.

00001426de Fix webgl CMakeLists.txt setup 
It looks like #7 didn't update CMakeLists.txt properly - defines
specified with -D have to be added as compile definitions.

Additionally, -O3 must be specified redundantly as a compile option and
as a link option - compile option makes .wasm bits small & fast, and
link option enables JS minifier.

After this fix CMake build results in minimal js/wasm files as well.

ad308cc26c Adding encoder level vs. perf/quality graph. 2019-05-31 15:42:12 -07:00
Rich Geldreich
f631b29a7e Frontend optimizations: Adding multiple compression levels to the encoder's frontend. Level 2 and 4 are equivalent to the initial release (default or -slower). Level 1 is now the new default, and is on average 21% faster than level 2. (Or more, up to 2-2.5x, on large images.) The help text documents what encoder features are used in each level. Level 0 is fine for most images, but is weak on artificial images and really large complex images. -slower now sets level 2 (not 4). 
Adding -only_etc1 command line option, because sometimes during unpack you only want the ETC1 images.

Total timing and avg. Y PSNR across 59 test images, quality 128:

L Time PSNR
0 121.4	35.45
1 172.4	36.87
2 216.0	37.13
3 511.4	37.15
4 665.9	37.41
5 1483.4	37.43

Initial release:
L Time PSNR
0 216.77	37.13
1 701.84	37.41

Adding -mip_srgb command line to example usages, so mipmap use gamma correct filtering. I will be changing the command line tool so this is automatically done unless -linear is specified. For now it must be manually specified.

f5d502912d Make codec options externally configurable and remove BC7 support 
This change makes it possible to exclude formats using compile time
options. BC7 is *never* exposed on the web and it has an absolutely huge
coding table which means we're just wasting space.

The impact on the file size is enormous, and it's used to output one
line into console which isn't exposed through the API anyhow.
