Clément Bœsch	3048fae63c	build: Avoid detecting bogus components named 'x' The function find_things() in configure is confused by component registration calls as part of multiline macros defining combined component registration. Coalesce those macros into one line to work around the issue. Signed-off-by: Diego Biurrun <diego@biurrun.de> Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Janne Grunau	9ac44ad9d0	h264: check SPS entries directly to detect pixel format changes Comparing AVCodecContext.pix_fmt against the get_pixel_format() return value has the side effect of calling the get_format() callback on each slice. Users of the callback will probably handle hardware accelerator initialization in the callback.	12 years ago

Anton Khirnov	7d84826400	cavs: deMpegEncContextize It does not use any of the mpegvideo infrastructure, just a few fields from the context. Fixes a segfault with the emu edge flag, since emu edge buffer is now allocated as a part of the frame buffer allocation and cavs calls ff_get_buffer() directly, it does not use mpegvideo buffer management. Fixes a memleak of the last frame.	12 years ago

Janne Grunau	1f4ea4e068	mpegvideo: initialize videodsp with correct pixel depth Fixes decoding of 9/10 bit per pixel h264 videos as reported in https://bugzilla.libav.org/show_bug.cgi?id=404 .	12 years ago

Anton Khirnov	51648da4dc	xan: remove a trivially true if(). This function used to be shared with the xxan decoder, but that is not true anymore.	12 years ago
Anton Khirnov	99e36ddd3e	ansi: do not depend on get_buffer() initializing the frame. The background changes from 128 (used by the default/cmdutils get_buffer()) to 0. This looks more correct.	12 years ago

Anton Khirnov	8adfacff5c	zmbv: remove some pointless comments and empty lines	12 years ago
Anton Khirnov	c6303f8d70	yop: simplify/sanitize the decoding loop Do not overwrite linesize set by get_buffer(). The last frame in the FATE test is not decoded anymore, since the file is cut and a part of it is missing.	12 years ago

Martin Storsjö	0940580adb	lavc: Correct the description of pkt_dts The description as updated in 6e5c44b0f made it sound like it is handled exactly like the pts, which it is not. Clarify that it is the packet that triggered returning the frame instead of just the last avpacket (in case of frame threading, it won't be the dts of the last packet).

Justin Ruggles	5778299c7e	ttadec: fix last frame handling when seeking Using a frame count, as is done currently, does not work at all with seeking. Instead, when the number of samples in the final frame has been decoded, we check if only the 32-bit CRC is remaining. If so, we assume that it is the final frame. There is no longer a need to keep total_frames in TTAContext.	12 years ago
Justin Ruggles	68a04b0cce	alacdec: do not be too strict about the extradata size Sometimes the extradata has duplicate atoms, but that shouldn't prevent decoding. Just ensure that it is at least 36 bytes as a sanity check. CC: libav-stable@libav.org	12 years ago

Luca Barbato	6906b19346	lavc: add missing files for arm Across the many retouches those did not make the main commit.	12 years ago
Ronald S. Bultje	8c53d39e7f	lavc: introduce VideoDSPContext Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch().

Janne Grunau	45635885e4	mpegvideo: increase edge_emu_buffer size for VC1 The VC1 decoder uses edge_emu_buffer simultaneously for luma and chroma and needs more space. That was not a problem before `f1d8763a02` since the size for edge_emu_buffer was always calculated with 2 byte per pixel since the linesize was not known. Fixes occasionally fate errors in vc1_sa10143.	12 years ago

Janne Grunau	9e696d2e5f	h264: support frame parameter changes during frame-mt Fixes CVE-2012-2782.	12 years ago
Janne Grunau	f1d8763a02	mpegvideo: allocate scratch buffers after linesize is known Since we can't know which stride a custom get_buffer() implementation is going to use we have to allocate this scratch buffers after the linesize is known. It was pretty safe for 8 bit per pixel pixel formats since we always allocated memory for up to 16 bits per pixel. It broke hoever with cmdutis.c's alloc_buffer() and high pixel bit depth since it allocated larger edges than mpegvideo expected. Fixes fuzzed sample nasa-8s2.ts_s244342.	12 years ago
Michael Niedermayer	ed2d7d5868	ff_h264_direct_ref_list_init: fix B slice check. Fixes null pointer dereference. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	12 years ago

Michael Niedermayer	c9aab8a123	h264: use mbaff ref indices in fill_colmap() only for mbaff references Prevents writing beyond array bounds. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	12 years ago
Janne Grunau	61c6eef545	h264: prevent decoding of slice NALs in extradata It is not posible to call get_buffer during frame-mt codec initialization. Libavformat might pass huge amounts of data as extradata after parsing broken files. The 'extradata' for the fuzzed sample sample_varPAR_s5374_r001-02.avi is 2.8M large and contains multiple slices.	12 years ago

Janne Grunau	27c8337e59	h264-mt: handle NAL_DPAs before calling ff_thread_finish_setup Since a NAL_DPA can start a new frame it has to be handled before ff_thread_finish_setup is called.	12 years ago
