  1. 2ab5ea6 Add the ability to benchmark YCCK JPEG compression/decompression. This is particularly useful since that is the only way to test the performance of the "plain" upsampling routines, which are accelerated on some platforms. by DRC · 10 years ago
  2. f5644c3 Ensure that tjFree() is used for any JPEG buffers that might have been dynamically allocated by the compress/transform functions. To keep things simple, we use tjAlloc() for the statically-allocated buffer as well, so that tjFree() can always be used to free the buffer, regardless of whether it was allocated by tjbench or by the TurboJPEG library. This fixes crashes that occurred on Windows when running tjunittest or tjbench with the -alloc flag. by DRC · 10 years ago

  4. 684ace1 Extend tjbenchtest so that it tests the dynamic JPEG buffer allocation feature in TurboJPEG. Disable the tiling feature in TJBench whenever dynamic buffer allocation is enabled (because the tiling feature requires a separate buffer for each tile, using it successfully with dynamic buffer allocation would require a separate TurboJPEG compressor instance for each tile, and it's not worth going to that trouble right now.) by DRC · 10 years ago

  10. 78b227e Oops. This code should not have been removed. It is necessary for generating the error images. by DRC · 11 years ago
  11. ce6891f If we have transformed a 4:2:2 or 4:4:0 image in any way that transposes the horizontal and vertical dimensions, then we need to inform the decompression function that the subsampling type has changed. Otherwise, tjDecodeYUV() will not produce correct results. by DRC · 11 years ago
  12. adf5551 Execute warmup runs with tjTransform() as well by DRC · 11 years ago
  13. e1efc8a Fix a couple of output formatting issues by DRC · 11 years ago
  14. 95e4cb2 Since we now have a complete set of YUV functions, TJBench can be greatly simplified. It now tests YUV encoding/decoding as an intermediate step of JPEG compression/decompression, which eliminates the need for a separate YUV mode. Several other things have been streamlined in the process. by DRC · 11 years ago
  15. 0e9bf64 Fix a segfault that would occur in decompress-only mode if -alloc was specified without -tile. by DRC · 11 years ago

  17. a15f19f Wordsmithing & formatting tweaks by DRC · 11 years ago
  18. d4b453c Back-port the -subsamp option from 1.4 rather than use the hackish approach of replacing 4:2:2 with 4:4:0. This has the added advantage of allowing the user to test only a specific level of subsampling. by DRC · 11 years ago
  19. c6501f7 Add the ability to test scaling when decompressing to YUV; compression from YUV to JPEG; and YUV padding. Replace clunky -411 and -440 parameters with a -subsamp parameter that allows any of the subsampling options to be tested in isolation. by DRC · 11 years ago
  20. 07e982d Deprecate and undocument the FORCE{MMX|SSE|SSE2|SSE3} flags. These were originally introduced in TurboJPEG/IPP as a way to override the automatic CPU selection in the underlying IPP codec, which was closed source. They are not meaningful anymore, since libjpeg-turbo provides environment variables to accomplish the same thing and since it no longer necessarily uses x86 SIMD code behind the scenes. by DRC · 11 years ago
  21. c45653e Fix a couple of issues with return value checking. JFREAD(), which wraps fread(), will never return -1. fread() will instead return 0 or a short object count if an error occurs, and ferror() will return 1 in that case. The second issue was that we were assigning the return value of ftell() to an unsigned long prior to checking the value, so the value would never be < 0 if an error occurred. It would instead be (unsigned long)-1. by DRC · 11 years ago

  29. ffe4fc1 Fix the behavior of the alpha-enabled colorspace constants whenever libjpeg-turbo is built without SIMD support and merged upsampling is used. by DRC · 13 years ago
