Daniel Kang	67360ccd51	yadif: x86: fix build for compilers without aligned stack Manually load registers to avoid using 8 registers on x86_32 with compilers that do not align the stack (e.g. MSVC). Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Luca Barbato	e28ac6e5e2	lavc: introduce the convenience function init_get_bits8 Accept the buffer size in bytes and check for overflow before passing the value in bits to init_get_bits.	12 years ago
Luca Barbato	d9cf5f5169	lavc: check for overflow in init_get_bits Fix an undefined behaviour and make the function return a proper error in case of overflow. CC: libav-stable@libav.org	12 years ago
Anton Khirnov	90cfc084e3	avpacket: free side data in av_free_packet(). Freeing it in av_destruct_packet(), as is done currently, would mean that we allow it to be allocated with other means. But that would make av_packet_new_side_data() unsafe. Side data is not expected to be large, so copying it if required shouldn't be a problem.	12 years ago
Anton Khirnov	49dc82eef7	v4l2: do not assert on a value received from outside of Libav	12 years ago
Anton Khirnov	838b849e70	v4l2: set the average framerate instead of codec timebase. Codec timebase is supposed to be set by decoders only.	12 years ago
Anton Khirnov	246da0b135	v4l2: avoid pointless indirection. v4l2_read_header() does no cleanup, so it can return directly, without any need for goto.	12 years ago

Rémi Denis-Courmont	aaf9d0e8f3	vdpau: Add MPEG-1/2 decoding via hwaccel infrastructure Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Rémi Denis-Courmont	44e065d56c	vdpau: Add context and common helpers for hwaccel support Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Martin Storsjö	22c436c85e	rtpdec: Send a valid "delay since SR" value in the RTCP RR packets Previously, we always signalled a zero time since the last RTCP SR, which is dubious. The code also suggested that this would be the difference in RTP NTP time units (32.32 fixed point), while it actually is in in 1/65536 second units. (RFC 3550 section 6.4.1) Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	e568db4025	rtpdec: Calculate and report packet reception jitter This brings back some code that was added originally in `4a6cc061` but never was used, and was removed as unused in `4cc843fa`. The code is updated to actually work and is tested to return sane values. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	abae27ed3a	rtpdec: Fix the calculation of expected number of packets The base_seq variable is set to first_seq - 1 (in rtp_init_sequence), so no + 1 is needed here. This avoids reporting 1 lost packet from the start. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	0f94c0b1b6	fate: vp3: Fix fate-vp3-coeff-level64 test dependencies Also rename the test to reflect that the video track is Theora, not VP3.	12 years ago
Diego Biurrun	4d3b144c5e	fate: cosmetics: Order some test entries	12 years ago
Diego Biurrun	f89466ad6f	Add version bump and APIchanges entry for Add AV_PIX_FMT_VDPAU. Also fix a lavu version typo in APIchanges.	12 years ago
Rémi Denis-Courmont	169fb94f0f	pixfmt: add picture format for VDPAU Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Luca Barbato	f61272f0ef	ratecontrol: K&R cosmetic formatting Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Martin Storsjö	f6804c3e1b	rtpdec: Remove a useless todo comment The question can be answered: No, we do not know the initial sequence number from the SDP. In certain cases, it can be known from the RTP-Info response header in RTSP though. (In that case, we use it as timestamp origin, but not for rtp receiver statistics.) Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	54cb096ee4	rtsp: Remove an outdated comment It is unclear what the bug exactly was and if it ever was fixed, and we don't even support decoding via faad any longer. The comment has been present since `d0deedcb` in 2006. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	3900d53fb1	rtsp: Remove references to weirdly named variables in other files One of them is renamed now, but mentioning it by name serves no purpose here. The other table mentioned ceased to exist under that name in `4934884a1` in 2006. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	c44784c9bb	rtp: Rename a static variable to normal naming conventions Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	58b5971881	rtp: Cosmetic cleanup Remove leftover debug comments, fix brace placement and add whitespace, remove unnecessary and weirdly placed braces. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Marcin Juszkiewicz	d11cb13b0e	configure: enable pic for shared libs on AArch64 Signed-off-by: Marcin Juszkiewicz <marcin.juszkiewicz@linaro.org> Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Luca Barbato	c1d1ef4ecd	zmbv: Reset the decoder on keyframe errors Prevent the crash on fuzzed files as reported in bug 63.	12 years ago
Vladimir Pantelic	7b8c5b263b	vc1dec: prevent a crash due missing pred_flag parameter Handle pred_flag parameter not given to get_mvdata_interlaced() Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago

Diego Biurrun	f8936c6f90	fate: Split fate-siff test into demuxer and VB video decoder test	12 years ago
Martin Storsjö	76c40fbef0	rtpdec_vp8: Don't trim too much data from broken frames Previously, for broken frames, we only returned the first partition of the frame (we would append all the received packets to the packet buffer, then set pkt->size to the size of the first partition, since the rest of the frame could have lost data inbetween) - now instead return the full buffered data we have, but don't append anything more to the buffer after the lost packet discontinuity. Decoding the truncated packet should hopefully get better quality than trimming out everything after the first partition. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	3b366c3aa0	rtpdec_vp8: Simplify code by using an existing helper function Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	ed79093222	rtpdec: Add a terminating null byte at the end of the SDES/CNAME This is required by RFC 3550 (section 6.5): The list of items in each chunk MUST be terminated by one or more null octets, the first of which is interpreted as an item type of zero to denote the end of the list. This was implicitly added as padding before, unless the host name length matched up so no padding was added. This makes wireshark parse the packets properly if other RTCP items are appended to the same packet. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Luca Barbato	a800fd5fc7	yuv4mpeg: do not use deprecated functions Use the libavutil replacement.	12 years ago
Luca Barbato	fba8e5b608	oggdec: fix faulty cleanup prototype	12 years ago
Justin Ruggles	06deaf8ad3	idcin: return 0 from idcin_read_packet() on success. This matches the AVInputFormat.read_packet() API.	12 years ago
Justin Ruggles	5d0450461f	idcin: better error handling Add some additional checks for EOF and print error messages on an incomplete header or packet. FATE reference updated for id-cin-video due to the demuxer no longer returning a partial video packet at EOF.	12 years ago
Justin Ruggles	33f58c3616	idcin: check for integer overflow when calling av_get_packet() chunk_size is unsigned 32-bit, but av_get_packet() takes a signed int as the packet size.	12 years ago
Justin Ruggles	7040e479a1	idcin: allow seeking back to the first packet Also, do not allow seek-by-byte, as there is no way to find the next packet boundary.	12 years ago
Justin Ruggles	49543373f3	idcin: set AV_PKT_FLAG_KEY for video packets with a palette	12 years ago
Justin Ruggles	ccc0ffb1ba	idcin: set start_time and packet duration instead of manually tracking pts. Also, use 1 / sample_rate for audio stream time_base.	12 years ago
Justin Ruggles	4b840930da	idcin: set channel_layout	12 years ago
Justin Ruggles	12c2530b1d	idcin: fix check for presence of an audio stream	12 years ago
