Encode a large pixels in ADV202/ADV212

Hi Dave,

We also need to encode an image with total samples (1440x900=1.3M or 2.6M for YCbCr 4:2:2) larger than both the 1.048 Msamples/image limit in Custom Specific mode and the max tile sizes suppported.  Our output will be saved to a file(s) and ultimately viewed using a software decoder.

Can you please elaborate on your last response.  When you suggest keeping the codestreams separate, does that mean using raw mode with separate ADV212 chips (or making three passes with one chip if the data rate permits) for each component?  Will each separate component input still need to be separated into tiles?  How many different codestreams per image will be created and merged on the PC side for decode?  Can you provide more details on how they are merged on the PC side for decode?  Finally, is there an advantage to working in either RGB or YCbCr input format for this example?  My input is in RGB but I can change to YCbCr or YCbYCr 4:2:2 if it helps.

Thanks,

Keith,
