* [media] vivid-tpg: improve Y16 color setupHans Verkuil2015-06-061-2/+9
| | | | | | | | | | | | Currently the colors for the Y16 and Y16_BE pixelformats are in the range 0x0000-0xff00. So pure white (0xffff) is never created. Improve this by making white really white. For other colors the lsb remains 0 so vivid can be used to detect endian problems.

* [media] vivid: move PRINTSTR to separate functionsHans Verkuil2015-06-051-47/+81
| | | | | | | | | | | | | | | | | | | Commit 84cb7be43cec12868e94163c99fdc34c0297c3b8 broke vivid-tpg (uninitialized variable p). This patch takes a different approach: four different functions are created, one for each PRINTSTR version. In order to avoid the 'the frame size of 1308 bytes is larger than 1024 bytes' warning I had to mark those functions with 'noinline'. For whatever reason gcc seems to inline this aggressively and it is doing weird things with the stack. I tried to read the assembly code, but I couldn't see what exactly it was doing on the stack.

* [media] vivid-tpg: correctly average the two pixels in gen_twopix()Hans Verkuil2015-04-021-6/+42
| | | | | | | | | | | gen_twopix() is always called twice: once for the first and once for the second pixel.

* [media] vivid-tpg: precalculate downsampled linesHans Verkuil2015-04-021-2/+38
| | | | | | | | | | | | | | | | | When dealing with vertical downsampling two successive lines have to be averaged. In the case of the test pattern generator that only happens if the two lines are using different patterns. So precalculate the average between two pattern lines: one of pattern P and one of pattern P + 1. That way there is no need to do any on-the-fly downsampling: it's all done in the precalculate phase. This patch also implements horizontal downsampling in the precalculate phase. The only thing that needs to be done is to half the width since the actual downsampling happens when two pixels at a time are generated.

* [media] vivid-tpg: add hor/vert downsampling fieldsHans Verkuil2015-04-021-1/+6
| | | | | | | | | | | | This is step one of supporting horizontal and vertical downsampling. This just adds support for the h/vdownsampling fields and it increases the maximum number of planes to 3. Currently none of the planar formats need horizontal or vertical downsampling, so this change has no effect at the moment.

| | | | | | | | | | | | | | The successive TOP/BOTTOM fields did not move as they should: only every other field actually changed position. The cause was that the tpg needs to know if it is dealing with a FIELD_ALTERNATE case since that requires slightly different handling.

| | | | | | | | | | When converting to or from Y'CbCr and R'G'B' the Y offset depends on the quantization range: it's 0 for full and 16 for limited range. But in the code it was hardcoded to 16.

| | | | | | | | | | | The random_line buffer must be twice the maximum width, but it only allocated the maximum width, so it was only half the size it needed to be.
