Aneesh Dogra	9b55b4bb3a	4xm: Prevent buffer overreads. 4xm decoder while decoding i2 frames can overread the buffer if proper checks are not made. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	3fa646e859	Revert "4xm: Prevent buffer overreads." This reverts commit `295a7c0238`. The patch breaks decoding of regular files (e.g. fate-4xm-2).	13 years ago

Aneesh Dogra	4b84f68223	4xm: pass the correct remaining buffer size to decode_i2_frame(). frame_size is the number of bytes left in the packet, so if we are passing buf-4 we can safely read frame_size+4 bytes. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
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

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.

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	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

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.

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

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

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
