|
38 * The following macros return a specific feature of the draw item |
|
39 * passed as a parameter. |
|
40 * |
|
41 * |
|
42 * renDriNewSourceFlag |
|
43 * returns 1, if the draw item is a new source for macroblock copying, |
|
44 * otherwise, it returns 0, |
|
45 * see REN_EXTDRAW_NEW_SOURCE in renExtDrawParam_t |
|
46 * |
|
47 * renDriCopyNotCodedFlag |
|
48 * returns 1, if the draw item contains not-coded macroblock info, |
|
49 * otherwise, it returns 0, |
|
50 * see REN_EXTDRAW_COPY_NOT_CODED in renExtDrawParam_t |
|
51 * |
|
52 * renDriSnapshotFlag |
|
53 * returns 1, if the draw item is marked as a snapshot, |
|
54 * otherwise, it returns 0, |
|
55 * see REN_EXTDRAW_SNAPSHOT in renExtDrawParam_t |
|
56 * |
|
57 * renDriFreezeReleaseFlag |
|
58 * returns 1, if the draw item ends picture freezing, |
|
59 * otherwise, it returns 0, |
|
60 * see REN_EXTDRAW_SNAPSHOT in renExtDrawParam_t |
|
61 * |
|
62 * renDriNoStatusCallbackFlag |
|
63 * returns 1, if no status callback is called after this draw item is, |
|
64 * processed, |
|
65 * otherwise, it returns 0, |
|
66 * see REN_EXTDRAW_NO_STATUS_CALLBACK in renExtDrawParam_t |
|
67 * |
|
68 * renDriRate |
|
69 * returns the rate parameter of renExtDrawParam_t |
|
70 * |
|
71 * renDriScale |
|
72 * returns the scale parameter of renExtDrawParam_t |
|
73 * |
|
74 * renDriCodedMBs |
|
75 * returns a pointer to an unsigned char array of flags of coded MBs, |
|
76 * the array is indexed by scan-ordered macroblock index, |
|
77 * 1 means that the corresponding macroblock is coded, |
|
78 * 0 means that the corresponding macroblock is not coded |
|
79 * |
|
80 * renDriNumOfMBs |
|
81 * returns the number of macroblocks in the draw item |
|
82 * |
|
83 * renDriNumOfCodedMBs |
|
84 * returns the number of coded macroblocks in the draw item |
|
85 * |
|
86 * renDriBitmapWidth |
|
87 * returns the width of the bitmap to be displayed (in pixels) |
|
88 * |
|
89 * renDriBitmapHeight |
|
90 * returns the height of the bitmap to be displayed (in pixels) |
|
91 * |
|
92 * renDriBitmapImageSize |
|
93 * returns the size of the bitmap to be displayed (in bytes) |
|
94 * |
|
95 * renDriBitmapCompression |
|
96 * returns the compression ID number of the draw item |
|
97 * |
|
98 * renDriFrameNumber |
|
99 * returns the frame number of the draw item |
|
100 * (the lTime Parameter of renDrawParam_t) |
|
101 * |
|
102 * renDriRetFrame |
|
103 * returns the pointer to the function where to return the processed draw |
|
104 * item (the retFrame param of renDrawItem_t) |
|
105 * |
|
106 * renDriRetFrameParam |
|
107 * returns the parameter to pass to the function where to return |
|
108 * the processed draw item (the retFrameParam of renDrawItem_t) |
|
109 * |
