* rv34: DC-only inverse transformChristophe GISQUET2012-01-12
| | | | | | | | | | | | | | | When decoding coefficients, detect whether the block is DC-only, and take advantage of this knowledge to perform DC-only inverse transform. This is achieved by: - first, changing the 108x4 element modulo_three_table into a 108 element table (kind of base4), and accessing each value using mask and shifts. - then, checking low bits for 0 (as they represent the presence of higher frequency coefficients) Also provide x86 SIMD code for the DC-only inverse transform.

* rv34: joint coefficient decoding and dequantizationChristophe GISQUET2012-01-04
| | | | | | | | | | | Perform dequantization while decoding coefficients instead of performing it on the entire coefficients buffer. Since quantized coefficients are very sparse, this usually causes a small speedup. Speedup of around 1% on Panda board compared to the removed here neon code. Global speedup is probably around 3%.

* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use full internal pathname in doxygen @file directives.Diego Biurrun2009-02-01
| | | | | | | Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Globally rename the header inclusion guard names.Stefano Sabatini2008-08-31
| | | | | | | | | 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
