1File: h264dec_ldecode_macroblock.c
2Original provenience:
3
42015-12-21:
5- Filename changed to h264dec.c
6- global.h renamed to h264dec.h
7- Removed commented out includes
8- Removed all obsolete typedefs, enums and structs. Only remaining ones are
9 struct img_par and
10 enum SliceType
11- Renamed function decode_one_macroblock to h264dec_decode_one_macroblock
12- Function h264dec_decode_one_macroblock changed to void (i.e., removed statement return 0;)
13- Added functions h264dec_init, h264dec_return and main
14- Added forward declarations of all functions before the declarations of global
15 variables
16- Struct 'ImageParameters' renamed to 'h264dec_ImageParameters'
17- Re-ordered functions to fit template-order
18- Applied code formatting according to the following rules
19 (incomplete, to be discussed; I basically used astyle with the attached
20 options file):
21 - Lines shall not be wider than 80 characters; whenever possible, appropriate
22 line breaks shall be inserted to keep lines below 80 characters
23 - Indentation is done using whitespaces only, no tabs. Code is indented by
24 two whitespaces
25 - Two empty lines are put between any two functions
26 - In non-empty lists or index expressions, opening '(' and '[' are followed by
27 one whitespace, closing ')' and ']' are preceded by one whitespace
28 - In comma- or colon-separated argument lists, one whitespace is put after
29 each comma/colon
30 - Names of functions and global variables all start with a benchmark-specific
31 prefix (here: st_) followed by lowercase letter (e.g., st_square)
32 - For pointer types, one whitespace is put before the '*'
33 - Operators within expressions shall be preceded and followed by one
34 whitespace
35 - Code of then- and else-parts of if-then-else statements shall be put in
36 separate lines, not in the same lines as the if-condition or the keyword
37 "else"
38 - Opening braces '{' denoting the beginning of code for some if-else or loop
39 body shall be put at the end of the same line where the keywords "if",
40 "else", "for", "while" etc. occur
41- Added general TACLeBench header to beginning of source code \ No newline at end of file
