Ronald S. Bultje	6c4c27adb6	kgv1: release reference picture on size change. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	cd40c31ee9	matroska: don't overwrite string values until read/alloc was succesful. This prevents certain tags with a default value assigned to them (as per the EBML syntax elements) from ever being assigned a NULL value. Other parts of the code rely on these being non-NULL (i.e. they don't check for NULL before e.g. using the string in strcmp() or similar), and thus in effect this prevents crashes when reading of such specific tags fails, either because of low memory or because of targeted file corruption.

Ronald S. Bultje	830f70442a	fraps: release reference buffer on pix_fmt change. Prevents crash when trying to copy from a non-existing plane in e.g. a RGB32 reference image to a YUV420P target image Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

John Van Sickle	d6a77e2b97	docs: use -bsf:[vas] instead of -[vas]bsf. The latter syntax is now invalid. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Dale Curtis	b716542691	mpegaudiodec: Prevent premature clipping of mp3 input buffer. Instead of clipping extrasize based on EXTRABYTES, clip based on the amount of buffer actually left. Without this fix, there are warbles and other distortions in the test case below. http://kevincennis.com/mix/assets/sounds/1901_voxfx.mp3	13 years ago
Anton Khirnov	655b24c01c	lavf: move the packet keyframe setting code. compute_pkt_fields() is for unreliable estimates or guessing. The keyframe information from the parser is (at least in theory) reliable, so it should be used even when the other guessing is disabled with the AVFMT_FLAG_NOFILLIN flag. Therefore, move setting the packet keyframe flag based on parser information from compute_pkt_fields() to read_frame_internal().	13 years ago
Justin Ruggles	9677247b0a	oggenc: free comment header for all codecs fixes a memleak for Vorbis and Theora, where the comment header from avpriv_split_xiph_headers() is replaced by a buffer that must be freed separately.	13 years ago
Ronald S. Bultje	be129271ea	lcl: error out if uncompressed input buffer is smaller than framesize. This prevents crashes when trying to read beyond the end of the buffer while decoding frame data. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	ab492ca2ab	mjpeg: abort decoding if packet is too large. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	46b3fbc30b	golomb: use HAVE_BITS_REMAINING() macro to prevent infloop on EOF. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	b44b41633f	get_bits: add HAVE_BITS_REMAINING macro.	13 years ago
Anton Khirnov	5ff42e3138	lavf/output-example: use new audio encoding API correctly.	13 years ago
Anton Khirnov	6e9ed7c7ae	lavf/output-example: more proper usage of the new API. Passing the codec into avformat_new_stream() is preferred.	13 years ago
Alex Converse	447363870f	tiff: Prevent overreads in the type_sizes array. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Alex Converse	e32548d133	tiff: Make the TIFF_LONG and TIFF_SHORT types unsigned. TIFF v6.0 (unimplemented) adds signed equivalents.	13 years ago

Ronald S. Bultje	6d11057006	apetag: propagate errors. Fixes crashes if reading the tag value fails. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Christophe GISQUET	2784d18791	SBR DSP x86: implement SSE sbr_hf_g_filt Unrolling the main loop to process, instead of 4 elements: - 8: minor gain of 2 cycles (not worth the extra object size) - 2: loss of 8 cycles. Assigning STEP to a register is a loss. Output address (Y) is almost always unaligned. Timings: - C (32/64 bits): 117/109 cycles - SSE: 57 cycles Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	34454c761f	SBR DSP x86: implement SSE sbr_sum_square_sse The 32bits targets have been compiled with -mfpmath=sse for proper reference. sbr_sum_square C /32bits: 82c (unrolled)/102c C /64bits: 69c (unrolled)/82c SSE/32bits: 42c SSE/64bits: 31c Use of SSE4.1 dpps to perform the final sum is slower. Not unrolling to perform 8 operations in a loop yields 10 more cycles. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	2e74a5abc2	SBR DSP: use intptr_t for the ixh parameter. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	31632e73f4	swf: check return values for av_get/new_packet(). Prevents crashers when using the packet if allocation failed. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Derek Buitenhuis	480b133e6f	wavpack: Don't shift minclip/maxclip Since we are clipping before we shift the values to 16 or 32 bits, we should not shift the min/max clip values to compensate. Fixes 8 and 24 bit lossy decoding. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Martin Storsjö	ba605cef79	rtpenc: Expose the max packet size via an avoption This allows opting for a lower MTU than what the AVIOContext indicated, and allows writing into outputs that don't indicate an MTU at all (such as plain files, which is useful for testing). This also allows querying for the MTU via the avoption. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	f553462041	rtpenc: Move max_packet_size to a context variable This is in preparation for exposing this via an avoption. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	7337484ed2	rtpenc: Add an option for not sending RTCP packets Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Anton Khirnov	7340008f18	a64multienc: switch to encode2(). We have no decoder, so cannot test if the output is decodable.	13 years ago
Anton Khirnov	cfc6ab3199	a64multienc: don't write into output buffer when there's no output.	13 years ago

Anton Khirnov	2257f66ec5	lavc: drop libdirac encoder. Libschroedinger is the preferred way to encode dirac video now, it produces better output and has a nicer API.	13 years ago
