Note: According to [MS-RDPEGFX 2.2.4.4 RFX_AVC420_BITMAP_STREAM] the width and height of the MPEG-4 AVC/H.264 codec bitstream MUST be aligned to a multiple of 16. Hence the passed destination YUV420/CHROMA420 buffers must have been allocated accordingly !!

[MS-RDPEGFX 3.3.8.3.2 YUV420p Stream Combination] defines the following "Bx areas":

YUV420 frame (main view): B1: From Y444 all pixels B2: From U444 all pixels in even rows with even columns B3: From V444 all pixels in even rows with even columns

Chroma420 frame (auxillary view): B45: From U444 and V444 all pixels from all odd rows (The odd U444 and V444 rows must be interleaved in 8-line blocks in B45 !!!) B6: From U444 all pixels in even rows with odd columns B7: From V444 all pixels in even rows with odd columns

Microsoft's horrible unclear description in MS-RDPEGFX translated to pseudo code looks like this:

for (y = 0; y < fullHeight; y++) { for (x = 0; x < fullWidth; x++) { B1[x,y] = Y444[x,y]; } }

for (y = 0; y < halfHeight; y++) { for (x = 0; x < halfWidth; x++) { B2[x,y] = U444[2 * x, 2 * y]; B3[x,y] = V444[2 * x, 2 * y]; B6[x,y] = U444[2 * x + 1, 2 * y]; B7[x,y] = V444[2 * x + 1, 2 * y]; } }

for (y = 0; y < halfHeight; y++) { yU = (y / 8) * 16; // identify first row of correct 8-line U block in B45 yU += (y % 8); // add offset rows in destination block yV = yU + 8; // the corresponding v line is always 8 rows ahead

for (x = 0; x < fullWidth; x++) { B45[x,yU] = U444[x, 2 * y + 1]; B45[x,yV] = V444[x, 2 * y + 1]; } }
