* movtextdec: Don't emit errors for normal duration-end packets.Philip Langdale2012-08-15
| | | | | | | | The logic here was off. If the packet size is exactly two, then it's a well-formed empty subtitle, used to mark the end of the duration of the previous subtitle. Signed-off-by: Philip Langdale <philipl@overt.org>
* srtenc: Add timing-less "subrip" encoder.Philip Langdale2012-08-15
| | | | | | | | | Unsurprisingly, if a timing-less subrip decoder is desireable, an encoder is as well. With this in place, we can move on to remove the use of the old encoder/decoder with embedded timing and move all timing handling the (de)muxer where they belong.

* srtdec: Add timing-less "subrip" decoder.Philip Langdale2012-08-15
| | | | | | | | | | | | After various discussions, we concluded that, amongst other things, it made sense to have a separate subrip decoder that did not use in-band timing information, and rather relied on the ffmpeg level timing. As this is 90% the same as the existing srt decoder, it's implemented in the same file. Signed-off-by: Philip Langdale <philipl@overt.org>

| | | | | | | | | | | | | | | | | | 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.

| * x86: cabac: allow building with sunccMans Rullgard2012-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * x86: mlpdsp: avoid taking address of voidMans Rullgard2012-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
