* dsputil: Split off HuffYUV decoding bits into their own contextDiego Biurrun2014-05-271-0/+1
| | | | Also shorten HuffYUV context member names to avoid clutter.
* Remove unnecessary dsputil.h #includesDiego Biurrun2013-02-261-1/+0
|
* huffyuv: split encoder and decoder into separate files.Anton Khirnov2012-12-231-1420/+14
|
* lavc: fix decode_frame() third parameter semantics for video decodersAnton Khirnov2012-12-041-2/+2
| | | | It's got_frame, not data size
* Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormatAnton Khirnov2012-10-081-16/+16
|
* Remove some silly disabled code.Diego Biurrun2012-10-011-5/+0
|
* huffman: add ff_huff_gen_len_tableMichael Niedermayer2012-08-281-62/+3
| | | | | | The function will be used by utvideo as well. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* huffyuv: update to current coding styleLuca Barbato2012-08-271-521/+576
|
* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-071-5/+5
|
* cosmetics: Align codec declarationsMartin Storsjö2012-04-061-22/+28
| | | | | | | 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>
* huffyuv: add padding to classic (v1) huffman tables.Ronald S. Bultje2012-03-081-4/+6
| | | | | | | | | | We slightly overread the input buffer, so we require padding at the end of the buffer, as is documented in the get_bits API. Without padding, we'll read uninitialized data or beyond the end of the .rodata, which may crash. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* Replace computations of remaining bits with calls to get_bits_left().Alex Converse2012-03-051-2/+2
|
* huffyuv: do not abort on unknown pix_fmt; instead, return an error.Ronald S. Bultje2012-03-011-1/+1
| | | | | Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* huffyuv: switch to encode2().Anton Khirnov2012-02-201-9/+20
|
* huffyuv: error out on bit overrun.Ronald S. Bultje2012-02-171-1/+1
| | | | | | | | On EOF, get_bits() will continuously return 0, causing an infinite loop. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* dsputil: Add ff_ prefix to the dsputil*_init* functionsMartin Storsjö2012-02-151-1/+1

* avcodec: change number of plane pointers from 4 to 8 at next major bump.Justin Ruggles2011-12-021-3/+4
| | | | | | Add AV_NUM_DATA_POINTERS to simplify the bump transition. This will allow for supporting more planar audio channels without having to allocate separate pointer arrays.
* lavc: use designated initialisers for all codecs.Anton Khirnov2011-07-291-34/+30
| | | | It's more readable and less prone to breakage.

* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-261-4/+4
| | | | | | | 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 Biurrun2010-04-201-1/+1
| | | | | | | | 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

* Implement alpha channel decoding for BGR HuffYUV.Alexander Strange2010-01-141-6/+10
| | | | | | | Since BGR24 is decoded as BGR32, fill its alpha channel with 255 using the appropriate predictors. Originally committed as revision 21211 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Fix passing of unaligned addresses to dsputil diff_bytes() byJeff Downs2009-05-231-4/+4
| | | | | | | | | | | | changeing calls to sub_left_prediction such that the source frame data pointers are no longer offset to skip the initial elements. This keeps them properly aligned for the subsequent call to diff_bytes. Changes encoding offset to compensate.
