Aneesh Dogra	893f137679	4xm: fix calculation of the next output line position in decode_i2_frame(). The current code doesn't work unless width is an exact multiple of 16. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Anton Khirnov	d09298f0d6	4xm: remove unused variables.	13 years ago
Shitiz Garg	355d917c0b	4xm: Add a check in decode_i_frame to prevent buffer overreads Fixes bugzilla #135 Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Aneesh Dogra	1443ea93d9	4xm: Use bytestream2 functions to prevent overreads Fixes Bug 110. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Justin Ruggles	bc78ceec2b	4xm: remove unneeded check for remaining unused data. This is unnecessary complication that only prints a message and does not affect decoding.	13 years ago
Michael Niedermayer	e1ba29c764	4xm: check if there are bits left in decode_i_block() Fixed Ticket753 Bug Found by: Diana Elena Muscalu Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Reimar Döffinger	371e165443	Try to set AVFrame.reference to correct values. I am not sure these new values are correct, not am I sure the semantics are a good idea since we do not seem to make any use of them but they caused a lot of confusion, but this seems to make things closer to matching the documentation.

Laurent Aimar	4a8ff0636d	Prevent NULL dereference when the huffman table is invalid in the 4xm decoder. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Stefano Sabatini	01042d4123	lavc: set defaults in internal codec frames This is required specifically for setting frame->format to -1, otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading the format from the output decoded frame will get misled. In particular fix regressions occurring with the pending vsrc_buffer patch.	14 years ago
Stefano Sabatini	ce5e49b0c2	replace deprecated FF__TYPE symbols with AV_PICTURE_TYPE_	14 years ago
Stefano Sabatini	975a1447f7	Replace deprecated FF__TYPE symbols with AV_PICTURE_TYPE_. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Stefano Sabatini	10aa5a6c42	4xm: use reget_buffer() in decode_frame() Also remove unnecessary call to avctx->release_buffer(). reget_buffer is required since apparently the codec needs to be feeded with the previous frame data. Releasing the frame and using get_buffer was working only in the case get_buffer() was returning the old frame data, and resulting in playback artifacts otherwise. Fix trac issue #85.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	e7e2df27f8	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `d36beb3f69`)	14 years ago

Måns Rullgård	e6b22522c9	bswap: change ME to NE in macro names Other parts of FFmpeg use NE (native endian) rather than ME (machine). This makes it consistent. Originally committed as revision 24169 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	84dc2d8afa	Remove DECLARE_ALIGNED_{8,16} macros These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	238ef6dadd	Add a av_fast_malloc function and replace several uses of av_fast_realloc, thus avoiding potential memleaks and pointless memcpys. Originally committed as revision 18470 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	9bf993a5b5	Use void * instead of uint8_t * for the destination buffer for dsp.bswap_buf where easily possible (mimic, eatqi, 4xm). This allows to avoid a typecast. Originally committed as revision 18469 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	2a0241ae12	Get rid of INIT_VLC_USE_STATIC in 4xm. Originally committed as revision 18435 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Carl Eugen Hoyos	e161e007be	Use INIT_VLC_USE_STATIC and not its value "1". Originally committed as revision 18430 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Daniel Verkamp	5ef251e504	Add missing av_cold in static init/close functions. Patch by Daniel Verkamp daniel at drv dot nu. Originally committed as revision 17526 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
