Paul B Mahol	14c98973f5	apetag: do not leak memory if avio_read() fails Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	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	ff311c0918	lavc: drop encode() support for video. All video encoders have been converted to encode2(), all new encoders should also use only encode2().	13 years ago
Anton Khirnov	171273fec8	snowenc: switch to encode2().	13 years ago
Anton Khirnov	8d3348c2c4	snowenc: don't abuse input picture for storing information.	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	62acb4937e	tiffenc: properly forward error codes in encode_frame().	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

Anton Khirnov	0ecf54f9dc	flashsvenc: switch to encode2().	13 years ago
Diego Biurrun	b315042c8c	Remove libpostproc. This library does not fit into Libav as a whole and its code is just a maintenance burden. Furthermore it is now available as an external project, which completely obviates any reason to keep it around. URL: http://git.videolan.org/?p=libpostproc.git	13 years ago
Ronald S. Bultje	01cb62aba2	lcl: don't overwrite input memory. If the PNG filter is enabled, a PNG-style filter will run over the input buffer, writing into the buffer. Therefore, if no zlib compression was used, ensure that we copy into a temporary buffer, otherwise we overwrite user-provided input data.	13 years ago
Ronald S. Bultje	1d8c4af396	swscale: take first/lastline over/underflows into account for MMX. Fixes crashes for extremely large resizes (several 100-fold). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	491865b57d	swscale: fix underflows in firstline calculations for extreme resizes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Anton Khirnov	a5f848c86d	libxavs: split extradata writing out of encode_nals(). This is done in preparation for the following patch implementing encode2(). This commit is analogous to `05d699222d` for libx264.	13 years ago
Anton Khirnov	8e8124e173	ljpegenc: switch to encode2().	13 years ago
Ronald S. Bultje	2b83e8b700	truemotion2: error out if the huffman tree has no nodes. This prevents crashers and errors further down when reading nodes in the empty tree. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Martin Storsjö	ada4e362b9	rtpenc: Add an error message Also return a proper error code. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	c4584f3c1f	rtpenc: Allow packetizing H263 according to the old RFC 2190 According to newer RFCs, this packetization scheme should only be used for interfacing with legacy systems. Implementing this packetization mode properly requires parsing the full H263 bitstream to find macroblock boundaries (and knowing their macroblock and gob numbers and motion vector predictors). This implementation tries to look for GOB headers (which can be inserted by using -ps <small number>), but if the GOBs aren't small enough to fit into the MTU, the packetizer blindly splits packets at any offset and claims it to be a GOB boundary (by using Mode A from the RFC). While not correct, this seems to work with some receivers. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	c2ff63e3ac	rtpenc: Move the trailing comma into FF_RTP_FLAG_OPTS This simplifies adding more flags to the macro. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Ronald S. Bultje	1254022ea7	swscale: fix filtersize clipping. if srcW<=2, clip(x, 1, srcW-2) still allows srcW to be < 1.	13 years ago
Rafaël Carré	562ebc3077	dxva2: don't check for DXVA_PictureParameters->wDecodedPictureIndex This structure is well defined by Microsoft at: http://msdn.microsoft.com/en-us/library/windows/hardware/ff564012(v=vs.85).aspx Thus, the wDecodedPictureIndex member is guaranteed to exist. Also, both the MPEG-2 and VC-1 hwaccel decoders depend on this struct member, but only the VC-1 decoder was disabled if the check failed. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Paul B Mahol	15b4b505c2	img2: split muxer and demuxer into separate files Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Ronald S. Bultje	aac07a7a4c	rm: prevent infinite loops for index parsing. Specifically, prevent jumping back in the file for the next index, since this can lead to infinite loops where we jump between indexes referring to each other, and don't read indexes that don't fit in the file. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
