Vittorio Giovara	9b749c8274	h264: move relevant fields from Picture to H264Picture	11 years ago
Vittorio Giovara	d66e305bd1	er: move relevant fields from Picture to ERPicture This is done to disentangle ER from mpegvideo. In order to use a classic Picture, callers can use ff_mpeg_set_erpic() or use a custom function to set the fields. Please note that buffers need to be allocated before calling ff_er_frame_end().	11 years ago

Diego Biurrun	f2408ec9d7	Give IDCT matrix transpose macro a more descriptive name This also avoids a macro name clash and related warning on ARM.	11 years ago

Vittorio Giovara	f777504f64	h264: Lower bound check for slice offsets And use the value from the specification. Sample-Id: 00000451-google Found-by: Mateusz j00ru Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago

Vittorio Giovara	3a05767028	h264: store current_sps_id inside the current sps In preparation for MVC support.	11 years ago
Vittorio Giovara	73e8fab31d	h264: print values in case of error Also make error style consistent and drop redundant information.	11 years ago
Janne Grunau	f795a8a8bf	h264: make context_count unsigned Removes the bogus but scary looking warning 'libavcodec/h264.c:4529:49: warning: array subscript is below array bounds [-Warray-bounds]'.	11 years ago
Anton Khirnov	1f097d168d	h264: reset data partitioning at the beginning of each decode call Prevents using GetBitContexts with data from previous calls. Fixes access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Janne Grunau	fb0c9d41d6	avutil: remove timer.h include from internal.h Added libavutil/timer.h include to all files with {START,STOP}_TIMER.	11 years ago
Janne Grunau	ea49f60523	h264: skip chroma edges at the picture boundary while deblocking 4:4:4 This handles macroblock edges for the chroma components in the same way as for the luma compoment for 4:4:4 streams. The Spec explicitly states that the deblocking filter is not applied to edges at the boundary of the picture. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Anton Khirnov	8b2e5e42bb	h264: check that an IDR NAL only contains I slices Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	0652e024c6	h264: reset ref count if decoding the slice header fails Otherwise the ER code might try to use some already freed references. Fixes possible access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	00dbff4c3e	h264: do not call field_end if we do not have a current picture Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	7f0e81db3c	h264: limit allowed pred modes in ff_h264_check_intra_pred_mode() to 3 Higher modes are not allowed for 16x16/chroma, which is what this function is used for. Otherwise this function would return 0 (vertical prediction) for invalid higher modes, which could result in invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	d1b3fabe69	h264: reset first_field if frame_start() fails for missing refs In this case we may not have a current frame, while first_field being set implies we do. Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	9eef9eb301	h264: check that execute_decode_slices() is not called too many times Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	bfd26b7ce6	h264: reject mismatching luma/chroma bit depths during sps parsing There is no point in delaying the check and it avoids bugs with a half-initialized context. Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	9a026c7298	h264: rebuild the default ref list if the reference count changes Fixes possible access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	58312b2472	h264: reset data_partitioning if decoding the slice header for NAL_DPA fails If it was set before then we can end up trying to decode a slice without a valid slice header, which can lead to invalid memory access. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Luca Barbato	4d2bb28931	h264: namespace the decode function Make much easier debugging.	11 years ago
Anton Khirnov	598ce4ab4f	h264: call av_frame_unref() instead of avcodec_get_frame_defaults(). This is a temporary workaround to allow deprecating avcodec_get_frame_defaults(). The proper solution will be using a properly allocated AVFrame in Picture.	11 years ago
Vittorio Giovara	5b10ef729f	h264: parse frame packing arrangement SEI messages and save relevant stereo3d information	11 years ago
Anton Khirnov	f0259a587e	h264: check buffer size before accessing it Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	a553c6a347	lavc: use buf[0] instead of data[0] in checks whether a frame is allocated data[0] may be NULL for valid frames with hwaccel pixel formats.	11 years ago
Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Anton Khirnov	9eda9d3322	h264: free the tables and uninitialize the context on flush Prevents referencing empty frames when the first packet after the flush does not contain a frame.	11 years ago
Luca Barbato	08303d7741	hwaccel: Simplify ff_find_hwaccel It is always called by passing fields from an AVCodecContext.	11 years ago
John Stebbins	28096e0a80	h264: wait for initial complete frame before outputing frames This can be optionally disabled whith the "output_corrupt" flags option. When in "output_corrupt" mode, incomplete frames are signalled through AVFrame.flags FRAME_FLAG_INCOMPLETE_FRAME. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Derek Buitenhuis	58d13cea30	h264: Check all allocations Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
