* rv34: 1-pass inter MB reconstructionChristophe GISQUET2012-01-16
| | | | Implement 1-pass inverse transform and reconstruction for inter blocks.
* rv34: Intra 16x16 handlingChristophe GISQUET2012-01-16
| | | | | | | Extract processing of intra 16x16 blocks from intra macroblock processing. Also implement a function performing inverse transform and block reconstruction for DC-only blocks in 1 pass instead of 2.
* rv34: Inter/intra MB code splitChristophe GISQUET2012-01-16
| | | | | | | | Split inter/intra macroblock handling code. This will allow further optimizations such as performing inverse transform and block reconstruction in a single pass as well as specialize code. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* rv34: fix and optimise frame dependency checkingJanne Grunau2012-01-12
| | | | | | | | The sporadic threading errors during fate-rv30 were caused by calling ff_thread_await_progress with mb row -1 as argument. That returns immediately since progress is initialized to -1. Not yet computed motion vectors from the reference could be used for the first macroblocks.
* 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: use get_bits_left()Janne Grunau2012-01-10
| | | | | It is not necessary to store the bit stream length in a RV34DecContext field.
* rv34: fix invalid memory access for small video dimensionsJohn Brooks2012-01-04
| | | | | | | | | For small video dimensions calculations of the upper bound for pixel access may result in negative value. Using an unsigned comparison works only if the greater operand is non-negative. This is fixed by doing edge emulation explicitly for such conditions.

* 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%.

* rv34: check that subsequent slices have the same type as first one.Kostya Shishkov2011-09-12
| | | | | | | | This prevents some crashes when corrupted bitstream reports e.g. P-type slice in I-frame. Official RealVideo decoder demands all slices to be of the same type too. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* doxygen: Prefer member groups over grouping into modulesReinhard Tartler2011-07-02
| | | | | | | | | Before this, almost all module groups have been used for grouping functions and fields in structures semantically. This causes them to not appear properly in the file documentation and needlessly clutters up the "Modules" index. Additionally, this commit streamlines some spelling and appearances.
* Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 ↵Oskar Arvidsson2011-05-10
| | | | | | | | | | | | | | | | | decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
