* tiffdec: support predictor type 2 with RGB48 pixel formatJean First2014-04-12
|
* tiffdec: remove an unneeded variableJustin Ruggles2014-04-12
|
* tiff: use a better name and enum values for PhotometricInterpretationJustin Ruggles2014-04-12
| | | | Also add additional known values and log as missing features.
* tiffdec: use a single strip if RowsPerStrip is 0Justin Ruggles2014-04-12
| | | | | The spec does not specify that 0 is an error condition, and there are samples which use 0 when the whole image is in one strip.
* tiffdec: use bytestream2 to simplify overread/overwrite protectionJustin Ruggles2014-04-12
| | | | | | Based on a patch by Paul B Mahol <onemda@gmail.com> CC:libav-stable@libav.org
* tiffdec: use correct data type for palette entries and set alpha to 0xFFJustin Ruggles2014-04-12

* tiff: Make the TIFF_LONG and TIFF_SHORT types unsigned.Alex Converse2012-02-23
| | | | TIFF v6.0 (unimplemented) adds signed equivalents.
* tiffdec: fix out of bound reads/writesLaurent Aimar2011-10-10
| | | | Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* lavc: use designated initialisers for all codecs.Anton Khirnov2011-07-29

* tiff: print log in case of unknown / unsupported tag.Stefano Sabatini2011-06-05

* tiff: set palette in the context when specified in TIFF_PAL tagStefano Sabatini2011-05-24
| | | | | | | | | | | Since image initialization was moved after tag parsing, the palette needs to be specified in the context and then copied to the allocated image in init_image(). Fixes a regression with TIFF images that have palette data, trac issue #230, file Test_Flate_8bpp.tif. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* tiff: add support for SamplesPerPixel tag in tiff_decode_tag()Stefano Sabatini2011-05-12
| | | | | | | | | | | | | Format detection and internal frame initialization is moved to a separate init_image() function, which is called when all the tags have been read, and so both BitsPerSample and SamplesPerPixel information has been collected. This fixes decoding of the file 11.tiff from roundup issue #1925. Based on a patch by Kostya Shishkov <kostya.shishkov@gmail.com>. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* tiff: Prefer enum TiffCompr over int for TiffContext.compr.Stefano Sabatini2011-05-12
| | | | | | This is safer and helps debugging. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* tiff: add support for inverted FillOrder for uncompressed dataStefano Sabatini2011-05-11
| | | | | | Fix decoding of file b.tif, trac issue #168. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* 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.

* 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>

* 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
* Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini2010-03-30
