Anton Khirnov	a06b0b1295	h264: initialize H264Context.avctx in init_thread_copy This prevents using a wrong (first thread's) AVCodecContext if decoding a frame in the first pass over all threads fails.	10 years ago
Michael Niedermayer	61928b68dc	h264: Do not share rbsp_buffer across threads Signed-off-by: Luca Barbato <lu_zero@gentoo.org> CC: libav-stable@libav.org	10 years ago
Anton Khirnov	167e004e1a	h264: drop any pretense of support for data partitioning It does not work correctly and apparently never did. There is no indication that this (mis)feature is ever used in the wild or even that any software other than the reference supports it. Since the code that attempts to support it adds some nontrivial complexity and has resulted in several bugs in the past, it is better to just drop it.	10 years ago
Anton Khirnov	ecab21ac47	h264: do not reset the ref lists in flush_change() They are always constructed anew when needed, so there is no need to reset them explicitly.	10 years ago
Anton Khirnov	9404a47a2d	h264: move parser-only variables to their own context	10 years ago
Anton Khirnov	cf1e0786ed	error_resilience: move the MECmpContext initialization into ER code Currently, it needs to be initialized by the ER caller (which is currently either a mpegvideo decoder or h264dec). However, since none of those decoders use MECmpContext for anything except ER, it makes more sense to handle it purely inside ER.	10 years ago
Anton Khirnov	f9f883af4f	h264: simplify code in flush_dpb() There is no point in clearing reference explicitly, since that will be done as a part of ff_h264_unref_picture() right below.	10 years ago
Anton Khirnov	60d4c6ff76	h264: restore a block mistakenly removed in `e10fd08a` CC: libav-stable@libav.org Bug-ID: 781	10 years ago

Dale Curtis	56de2897a6	h264: Fix memory leak on ff_h264_decode_init() failure CC: libav-devel@libav.org	10 years ago
Vittorio Giovara	b1b1a7370e	display: fix order of operands CC: libav-stable@libav.org Bug-Id: CID 1238828 / CID 1238832	10 years ago
Anton Khirnov	7ea1b3472a	lavc: deprecate the use of AVCodecContext.time_base for decoding When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.	10 years ago
Michael Niedermayer	2cd7c99498	h264: reset ret to avoid propagating minor failures Unbreak `772d150a6e`. CC: libav-stable@libav.org Bug-Id: 750 / 905753 Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 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

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
