Hi all,
Thanks to Hank
, I've been playing with variable matrix in my SAP, generating a mpeg2 file with a different matrix in each GOP. I haven't had any problem (but normal as my player is a "chinise" one, that play almost everything).
The used values in this file are:
Code:
Default Luma and Chroma Intra Quant Matrix:
8 16 19 22 26 27 29 34
16 16 22 24 27 29 34 37

22 26 27 29 32 35 40 48
26 27 29 32 35 40 48 58
26 27 29 34 38 46 56 69
27 29 35 38 46 56 69 83
Default Luma and Chroma Non-Intra Quant Matrix:

To check the compatibility with others , I post here an ISO image of a DVD made with this variable matrix mpeg2 (the size is 15Mb):

Thanks to check that it works in your SAP.
