2013-10-31indeo3: stop using deprecated avcodec_set_dimensionsAnton Khirnov
2013-10-04cosmetics: Group .name and .long_name together in codec/format declarationsDiego Biurrun
2013-05-10indeo3: avoid writes without necessary alignment in copy_cell()Janne Grunau
Cells starting at a position aligned to 8 pixels but wider than 4 blocks are copied with 3 blocks per loop. This creates problems on the next loop iterations since the routine copying 2 blocks requires the same alignment on some architectures like ARM NEON.
2013-05-07indeo3: use unaligned reads on reference blocks.Anton Khirnov
They are not guaranteed to be aligned. Fixes Bug 503. CC:libav-stable@libav.org
2013-04-30indeo3: use put_pixels instead of put_no_rnd_pixels in copy_cell()Anton Khirnov
They are the same in this case, except put_pixels also has blocksizes smaller than 8.
2013-04-30indeo3: fix off by one in MV validity checkAnton Khirnov
CC:libav-stable@libav.org
2013-04-20indeo3: Use hpeldsp instead of dsputil for half-pel functionsRonald S. Bultje
This makes the Indeo 3 decoder independent of dsputil. Signed-off-by: Martin Storsjö <martin@martin.st>
2013-04-17indeo3: check motion vectors.Anton Khirnov
Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
2013-04-17indeo3: fix data size checkAnton Khirnov
The data offsets are relative to the bistream header, which is 16 bytes after the start of the data. Fixes invalid reads with corrupted files. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
2013-04-17indeo3: switch parsing the header to bytestream2Anton Khirnov
Also add an additional sanity check to the alt_quant table. Fixes invalid reads with corrupted files. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
2013-03-14avcodec: av_log_ask_for_sample() ---> avpriv_request_sample()Diego Biurrun
2013-03-08lavc decoders: work with refcounted frames.Anton Khirnov
2013-02-08indeo3: replace use of copy_block4 with put_pixelsMans Rullgard
The destination is sufficiently aligned for put_pixels here. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-12-05lavc: fix decode_frame() third parameter semantics for video decodersAnton Khirnov
It's got_frame, not data size
2012-12-05lavc: add a wrapper for AVCodecContext.get_buffer().Anton Khirnov
It will be useful in the upcoming transition to refcounted AVFrames.
2012-10-29indeo3: remove duplicate capabilities line.Anton Khirnov
2012-10-29lavc: add CODEC_CAP_DR1 to all video decoders missing themAnton Khirnov
2012-10-19indeo3: do not try to output more lines than we can fitKostya Shishkov
Internally chroma planes have multiple of four height while allocated image planes might be smaller if CODEC_FLAG_EMU_EDGE is set. Thus we should not output more lines of chroma than frame can accept. Also the decoder can be safely switched to direct rendering now.
2012-10-08Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormatAnton Khirnov
2012-09-29indeo3: fix out of cell write.Anton Khirnov
Fixes CVE-2012-2776. CC:libav-stable@libav.org Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind
2012-08-07Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov
2012-05-15indeo3: validate new frame size before resetting decoderKostya Shishkov
2012-05-15indeo3: when freeing buffers, set pointers referencing them to NULL as wellKostya Shishkov
2012-05-15indeo3: initialise pixel planes on allocationKostya Shishkov
This prevents decoder from reading garbage from it in case of errors later.
2012-05-15indeo3: ensure that decoded cell data is in 7-bit range as presumed by decoderKostya Shishkov
2012-05-02indeo3: fix motion vector validationHendrik Leppkes
The index of the motion vector has to be checked before being multiplied by 2 for the array index. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
2012-02-28Indeo3: fix crashes on corrupt bitstreams.Ronald S. Bultje
Splits at borders of cells are invalid, since it leaves one of the cells with a width/height of zero. Also, propagate errors on buffer allocation failures, so we don't continue decoding (which crashes). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

The new decoder is much smaller and has better code quality. Cleanup and fixes courtesy of Kostya Shishkov. Signed-off-by: Diego Biurrun <diego@biurrun.de>
2011-11-02Remove some stray unnecessary ffmpeg references.Diego Biurrun
2011-07-29lavc: use designated initialisers for all codecs.Anton Khirnov
It's more readable and less prone to breakage.
2011-05-04indeo3: Eliminate use of long.Alex Converse

Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-02-15Merge libavcore into libavutilReinhard Tartler
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.

2011-01-26Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò
None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
