DRC 7d9f758e52 For now, punt on trying to support fancy upsampling in tjDecodeYUV(). Fancy upsampling requires context rows and other refinements, which are difficult to implement correctly with the algorithm we're using. Longer-term, supporting fancy upsampling would probably require using the main buffer that libjpeg allocates.

DRC 15c0876191 Fix additional uninitialized values reported by valgrind

DRC c90144950f When tjDecodeYUV() is used with a "fresh" decompressor instance (one that hasn't been previously used to decompress a JPEG image), then it needs comps_in_scan, data_precision, and the quantization tables to be defined. This patch also extends TJUnitTest to check for this error.

DRC 20e158dcb7 Silence valgrind false positives about uninitialized values. Even with this patch, valgrind still complains about uninitialized values when decompressing or decoding to a buffer with an alpha-enabled colorspace. Not sure why this happens, but it occurs in libjpeg-turbo 1.3 as well, and only when the x86/x86-64 SIMD code is being used. It is my belief that these remaining warnings are also false positives, because if the output buffer is memset to all 0's prior to invoking tjDecodeYUV()/tjDecompress(), no errors are reported. If any of the alpha channel bits were in fact not being initialized, then they would still be 0 after invoking tjDecodeYUV()/tjDecompress(), and TJUnitTest would report an error.

DRC 2bdc0425df Go ahead and call jinit_master_decompress() rather than trying to reproduce its functionality. That function does a few things that we were missing, including allocating the range limit table used by the plain C color conversion code.

DRC 693f4a5600 Fix an issue that prevented tjEncodeYUV2() and TJCompressor.encodeYUV() from working properly if the source image was very tiny. Basically, jpeg_start_compress() was attempting to write the JPEG headers, which was overrunning the YUV buffer. This patch removes the call to jpeg_start_compress() in tjEncodeYUV2() and replaces it with calls to the individual routines that are necessary to initialize the color converter and downsampler. TJUnitTest has also been modified to test for this condition (the buffer size regression test now works in YUV mode.)

DRC 2885cf5830 Further examination of the code reveals that this change is unnecessary. The histogram stores a count of each color in the image, so it will always contain at least one non-zero element, and thus the total can never be zero. Since the histogram is generated from the image data and not read from the header, there is no chance that header corruption would affect it.

DRC a113506d17 Some motion JPEG implementations generate "abbreviated JPEG streams" (JPEG images without the default tables included) for some or all of the video frames, in order to save space. When these are encountered, it is generally expected that they will be decompressed using the default Huffman tables, so libjpeg-turbo now does this unless the tables have been explicitly specified by an application.
