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

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	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

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

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

Anton Khirnov	0584e3ca97	lavf: don't set AVCodecContext.has_b_frames in compute_pkt_fields(). It is not supposed to be done outside lavc. This is basically a revert of `818062f2f3`. It is unclear what issue this was supposed to fix, if it reappears again it will have to be fixed in a more proper place. The wtv-demux test change is because the sample starts with a B-frame.	13 years ago
Ronald S. Bultje	e30b3e59a4	rmdec: when using INT4 deinterleaving, error out if sub_packet_h <= 1. We read sub_packet_h / 2 packets per line of data (during deinterleaving), which equals zero if sub_packet_h <= 1, thus causing us to not read any data, leading to an infinite loop.

Martin Storsjö	0c7b8b758a	movenc: Buffer the mdat for the initial moov fragment, too This allows writing QuickTime-compatible fragmented mp4 (with a non-empty moov atom) to a non-seekable output. This buffers the mdat for the initial fragment just as it does for all normal fragments, too. Previously, the resulting atom structure was mdat,moov, moof,mdat ..., while it now is moov,mdat, moof,mdat. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Martin Storsjö	aa96d433e2	movdec: Don't parse all fragments if ignidx is set In nonseekable files, we already stop parsing the toplevel atoms after finding moov and one mdat. In large seekable files (or files that are seekable, but slowly, e.g. http), reading all the fragments at the start can take a considerable amount of time. This allows opting out from this behaviour. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	383a3b64cb	movdec: Restart parsing root-level atoms at the right spot If parsing moov+mdat in a non-seekable file, we currently abort parsing directly after parsing the header of the mdat atom. If we want to continue parsing later (if looking to parse later fragments), we need to skip past the content of the mdat atom, otherwise we end up parsing the content of the mdat atom as root level atoms.

Christophe GISQUET	b5696ff2b8	prores: use natural integer type for the codebook index The operations that use it require it to be promoted to a larger (natural) type and thus perform sign extension on it. While an optimal compiler may account for this, gcc 4.6 (for x86 Windows) fails. Using the natural integer type provides a 2% speedup for Win64 and 1% for Win32.
