Calculates the absolute frame number in the source file out of various variables in p_Img-> and p_Inp->.

Returns:
frame number in the file to be read
side effects
global variable frame_no updated -- dunno, for what this one is necessary

void copyblock_sp ( Macroblock *  currMB,
ColorPlane  pl,
int  block_x,
int  block_y

The routine performs transform,quantization,inverse transform, adds the diff. to the prediction and writes the result to the decoded luma frame. Includes the RD constrained quantization also.

Input:
block_x,block_y: Block position inside a macro block (0,4,8,12).
Output:
nonzero: 0 if no levels are nonzero. 1 if there are nonzero levels.
coeff_cost: Counter for nonzero coefficients, used to discard expensive levels.

Eric Setton Encoding of the chroma of a secondary SP / SI frame. For an SI frame the predicted block should only come from spatial pred. The original image signal is the error coefficients of a primary SP in the raw data stream the difference with the primary SP are :

  • the prediction signal is transformed and quantized (qpsp) but not dequantized
  • the resulting error coefficients are not quantized before being sent to the VLC.
