Andreas Rheinhardt	14dd0a9057	avcodec/cbs: Avoid leaving the ... out in calls to variadic macros According to C99, there has to be at least one argument for every ... in a variadic function-like macro. In practice most (all?) compilers also allow to leave it completely out, but it is nevertheless required: In a variadic macro "there shall be more arguments in the invocation than there are parameters in the macro definition (excluding the ...)." (C99, 6.10.3.4). CBS (not the framework itself, but the macros used in the cbs_*_syntax_template.c files) relies on the compiler allowing to leave a variadic macro argument out. This leads to warnings when compiling in -pedantic mode, e.g. "warning: must specify at least one argument for '...' parameter of variadic macro [-Wgnu-zero-variadic-macro-arguments]" from Clang. Most of these warnings can be easily avoided: The syntax_templates mostly contain helper macros that expand to more complex variadic macros and these helper macros often omit an argument for the .... Modifying them to always expand to complex macros with an empty argument for the ... at the end fixes most of these warnings: The number of warnings went down from 400 to 0 for cbs_av1, from 1114 to 32 for cbs_h2645, from 38 to 0 for cbs_jpeg, from 166 to 0 for cbs_mpeg2 and from 110 to 8 for cbs_vp9. These eight remaining warnings for cbs_vp9 have been fixed by switching to another macro in cbs_vp9_syntax_template: The fixed values for the sync bytes as well as the trailing bits for byte-alignment are now read via the fixed() macro (this also adds a check to ensure that trailing bits are indeed zero as they have to be).

Andreas Rheinhardt	a1a8815220	libavcodec: Reduce the size of some arrays This commit uses smaller types for some static const arrays to reduce their size in case the entries can be represented in the smaller type. The biggest savings came from inv_map_table in vp9.c.
