Mans Rullgard	0d230e9312	g723.1: simplify scale_vector() It is impossible for bits to be 15 here so the special case is not needed. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	a4b8fc3a8a	g723.1: simplify normalize_bits() This function is always called with a non-negative argument, so those special cases are not needed. In the places the argument might be zero, the return value for a zero argument does not matter since it would then be used to scale an array full of zeros.

Nicolas George	17e40236cb	dvdsubenc: set frame size in extradata.	12 years ago
Nicolas George	2dedd8f496	dvdsubenc: make it usable for transcoding. DVD subtitles packets can only encode a single rectangle: if there are several, copy them into a big transparent one. DVD subtitles rely on an external 16-colors palette: use a reasonable default one, stored in the private context, and encode it into the extradata, as specified by Matroska. TODO: allow to change the palette with an option. Each packet can use four colors out of the global palette. The old logic was to map transparent colors to the color 0 and all other colors to 3, 2, 1, cyclically in descending frequency order, completely disregarding the original color. Select the "best" four colors from the global palette, according to heuristics based on frequency, opacity and brightness, and arrange them in standard DVD order: background, foreground, outline, other. TODO: select the alpha value more finely; see if CHG_COLCON can allow more than 4 colors per packet. Reference: http://dvd.sourceforge.net/dvdinfo/spu.html With these changes, dvdsubenc can be used to transcode DVB subtitles and get a very decent result.	12 years ago

Mans Rullgard	8ec0204ee4	x86: cabac: allow building with suncc This fixes two issues preventing suncc from building this code. The undocumented 'a' operand modifier, causing gcc to omit a $ in front of immediate operands (as required in addresses), is not supported by suncc. Luckily, the also undocumented 'c' modifer has the same effect and is supported. On some asm statements with a large number of operands, suncc for no obvious reason fails to correctly substitute some of the operands. Fortunately, some of the operands in these statements are plain numbers which can be inserted directly into the code block instead of passed as operands. With these changes, the code builds correctly with both gcc and suncc. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	c8252e80eb	x86: mlpdsp: avoid taking address of void This code contains a C array of addresses of labels defined in inline asm. To do this, the names must be declared as external in C. The declared type does not matter since only the address is used, and for some reason, the author of the code used the 'void' type despite taking the address of a void expression being invalid. Changing the type to char, a reasonable choice since the alignment of the code labels cannot be known or guaranteed, eliminates gcc warnings and allows building with suncc.

Michael Niedermayer	603221ebd0	g723_1dec: inline normalize_bits() in scale vector and optimize it. many branches and cases of scale_vector are irrelevant for the case here and by inlining they can be reliably removed. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	20035fa241	g723_1dec: remove dead code that leaked in from libav It appears someone thinks this special case can be reached Well, it cannot, thus not only do we not need to optimize it we dont need it at all Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Mans Rullgard	138914dcd8	g723.1: do not bounce intermediate values via memory Although a reasonable compiler will probably optimise out the actual store and load, this operation still implies a truncation to 16 bits which the compiler will probably not realise is not necessary here.
