Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk

avcodec/rv40: Make the tables used to initialize VLCs smaller After permuting the codes, symbols and lengths tables used to initialize the VLC so that the codes are ordered from left to right in the Huffman tree, the codes become redundant as they can be easily computed from the lengths at runtime; in this case one has to use explicit symbol tables, but all the symbols used here fit into an uint8_t, whereas some codes needed uint16_t. This saves about 1.6KB. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

avcodec/rv40: Make better use of VLC symbols table RealVideo 4.0 has a VLC that encodes two intra types per code; each intra type is in the range 0..8 (inclusive) and up until now the VLC used symbols in the range 0..80; one type was encoded as the remainder when dividing the symbol by 9 whereas the other type was encoded as symbol / 9. This is suboptimal; a better way would be to use the high and low nibble to encode each symbol. But an even better way is to use 16bit symbols so that the two intra types can be directly written as a 16bit value. This commit implements this; in order to avoid huge tables the symbols are stored as uint8_t with high and low nibbles encoding one type each; they are only unpacked to uint16_t during initialization.

avcodec/rv40: Make the tables used to initialize VLCs smaller After permuting the codes, symbols and lengths tables used to initialize the VLC so that the codes are ordered from left to right in the Huffman tree, the codes become redundant as they can be easily computed from the lengths at runtime; in this case one has to use explicit symbol tables, but all the symbols used here fit into an uint8_t, whereas some codes needed uint16_t.

avcodec/rv40: Make the tables used to initialize VLCs smaller After permuting the codes, symbols and lengths tables used to initialize the VLC so that the codes are ordered from left to right in the Huffman tree, the codes become redundant as they can be easily computed from the lengths at runtime; in this case one has to use explicit symbol tables, but all the symbols used here fit into an uint8_t, whereas some codes needed uint16_t.

Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk
