* Reduce the scope of some variablesDiego Biurrun2016-05-11
| | | | | This avoids unused variable warnings after the next version bump. Also drop a trace level av_log() call that is in the way.
* pgssub: Fix subpicture colorspace and rangeJan Ekström2016-05-10
| | | | | | | | | Widen the values from limited to full range and use BT.709 where it should be used according to the video resolution: SD is BT.601, HD is BT.709 Default to BT.709 due to most observed HDMV content being HD.
* pgssubdec: fix API compability layerPetri Hintukainen2015-11-26
| | | | | | | Copy pointers to AVPicture after memory has been allocated. Fixes NULL pointers in AVPicture after a17a7661906ba295d67afd80ac0770422e1b02b3. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lavc: Add data and linesize to AVSubtitleRectVittorio Giovara2015-10-21
| | | | | | | | | | | | Use the new fields directly instead of the ones from AVPicture. This removes a layer of indirection which serves no pratical purpose whatsoever, and will help in removing AVPicture structure completely later. Every subtitle encoder/decoder seamlessly points to the new arrays, so it is possible to deprecate AVSubtitleRect.pict. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* lavc: Replace av_dlog and tprintf with internal macrosVittorio Giovara2015-04-19

* pgssubdec: Check RLE size before copyingMichael Niedermayer2014-08-01
| | | | | | | | | | | | | Make sure the buffer size does not exceed the expected RLE size. Prevent an out of array bound write. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Bug-Id: CVE-2013-0852 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* pgssubdec: handle more complex PGS scenariosJohn Stebbins2014-06-30
| | | | | | | | | Add ability to handle multiple palettes and objects simultaneously. Each simultaneous object is given its own AVSubtitleRect. Note that there can be up to 64 currently valid objects, but only 2 at any one time can be "presented". Signed-off-by: Anton Khirnov <anton@khirnov.net>
* dsputil: Move ff_zigzag_direct and ff_crop_tab declarations to mathops.hDiego Biurrun2014-03-22
|
* dsputil: cosmetics: Lose camelCase on ff_cropTbl and ff_squareTbl namesDiego Biurrun2014-03-13
| | | | Also switch from "tbl" to "tab" name suffixes.
* pgssubdec: stop using deprecated avcodec_set_dimensionsAnton Khirnov2013-10-31
|
* cosmetics: Group .name and .long_name together in codec/format declarationsDiego Biurrun2013-10-03
|
* PGS subtitles: Set AVSubtitle pts valueJohn Stebbins2012-11-18
| | | | | | pts should be that of the packet containing the presentation segment. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* PGS subtitles: Expose forced flagJohn Stebbins2012-11-02
| | | | | | | Useful for detection of subtitles displayed during foreign language scenes. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormatAnton Khirnov2012-10-08
|
* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-07
|
* cosmetics: Align codec declarationsMartin Storsjö2012-04-06
| | | | | | | Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>
* Fix a bunch of common typos.Diego Biurrun2012-03-09
|
* lavc: use designated initialisers for all codecs.Anton Khirnov2011-07-29
| | | | It's more readable and less prone to breakage.
* cosmetics: fix some then/than typosDiego Biurrun2011-06-30
|
* Replace some av_log/printf + #ifdef combinations by av_dlog.Diego Biurrun2011-06-07
|
* pgssubdec: fix incorrect colors.Alexandre Colucci2011-05-24
| | | | | | | | | On Blu-ray colors are stored in the order YCrCb (and not YCbCr) as mentioned in the specifications: see System Description Blu-ray Disc Read-Only Format, 9.14.4.2.2.1 Palette Definition Segment When decoding a Blu-ray subtitle, the colors were incorrectly set.

* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19

* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

* Replace dprintf with av_dlogLuca Barbato2011-01-29
| | | | dprintf clashes with POSIX.1-2008
* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Improve PGS parsing: the "state" field is not relevant to us,Reimar Döffinger2010-11-06
| | | | | | | | | the object number is, it determines whether we should continue parsing the presentation description and whether we should clear the subtitles on the next display command.

| | | | | | | | 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
