* rtpdec_h264: Check the available data length before readingMartin Storsjö2012-05-05
| | | | | | This makes sure the length is checked for STAP-A type packets. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec_h264: Add input size checksIvan Kovtunov2012-05-05
| | | | | | This fixes crashes if given too short data packets. Signed-off-by: Martin Storsjö <martin@martin.st>
* ea: check chunk_size for validity.Ronald S. Bultje2012-05-04

* avformat: only fill-in interpolated timestamps if duration is non-zeroJustin Ruggles2012-05-03
| | | | | This avoids returning duplicate timestamps for multiple packets when the demuxer does not provide all timestamps and packet duration is not known.
* avformat: remove a workaround for broken timestampsJustin Ruggles2012-05-03
| | | | | | | This modifies pts in situations other than what was intended, leading to invalid timestamps. Reverts commit 90bb394dccacd10607153833a0aeba0d970dc8db

* mkv: mark corrupted packets and return themLuca Barbato2012-04-29
| | | | Do return error if memory allocation or I/O fails.
* mkv: forward EMBL block data errorLuca Barbato2012-04-29
| | | | Do not return 0 on error.
* segment: reorder seg_write_header allocationLuca Barbato2012-04-27
| | | | | As pointed by Paul B Mahol <onemda@gmail.com> the previous code could lead to null pointer dereference.
* avio: make avio_close(NULL) a no-opLuca Barbato2012-04-27
| | | | Its behaviour in line with ffurl_close(NULL).
* mov: Parse EC3SpecificBox (dec3 atom).Yusuke Nakamura2012-04-27
| | | | | | | | Skip to parse fields for additional independent substreams and its associated dependent substreams since libavcodec's E-AC-3 decoder does not support them yet. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
* mpegts: Make sure we don't return uninitialized packetsMartin Storsjö2012-04-27
| | | | | | | | | This fixes crashes, where the demuxer could return 0 even if the returned AVPacket isn't initialized at all. This could happen if running into EOF or running out of probesize with non-seekable sources. Signed-off-by: Martin Storsjö <martin@martin.st>

* avf: fix faulty check in has_durationLuca Barbato2012-04-25
| | | | An invalid duration is AV_NOPTS_VALUE not 0.
* isom: Support more DTS codec identifiers.Yusuke Nakamura2012-04-23
| | | | | | DTS LBR identifier ('dtse') is not included since libavcodec doesn't support it yet. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* matroska: Clear prev_pkt between seeks.Dale Curtis2012-04-23
| | | | | | | | | | | The new incremental parser doesn't always clear prev_pkt, however the packet queue is cleared when seeking. Which leads to a use-after-free. Verified using Valgrind. Signed-off-by: Dale Curtis <dalecurtis@chromium.org> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
* audemux: Add a sanity check for the number of channelsMichael Niedermayer2012-04-23
| | | | | | | Fixes a division by 0. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Martin Storsjö <martin@martin.st>
* matroska: Add incremental parsing of clusters.Dale Curtis2012-04-22
| | | | | | | | | | | | | | | | | | | | | | Reduces the amount of upfront data required for cluster parsing thus decreasing latency on seek and startup. The change in the seek-lavf_mkv FATE test is due to incremental parsing no longer reading as much data as the old parser and thus not having that additional data to generate index entries based on keyframes. Index entries are added correctly as the file is parsed. All FATE tests pass and Chrome has been using this patch for ~6 months without issue. Currently incremental parsing is not supported for files with SSA tracks since they require merging packets between clusters. In this case the code falls back to non-incremental parsing.

* mpegts: Try seeking back even for nonseekable protocolsMartin Storsjö2012-04-23
| | | | | | | | | | | | | | | | | The mpegts demuxer reads 5 KB at startup just for discovering the packet size. Since the default avio buffer size is 32 KB, the seek back to the start will in most cases be within the avio buffer, and will in most cases succeed even if the actual protocol isn't seekable. This makes the demuxer startup faster/with less data when reading data from a non-seekable input, by not skipping the first few KB. If it fails, don't warn if the protocol isn't seekable, making it behave as before in the failure case. Signed-off-by: Martin Storsjö <martin@martin.st>

* movenc: Support high sample rates in isomedia formats by setting the sample ↵Alex Converse2012-04-20

* avcodec: add a cook parser to get subpacket durationJustin Ruggles2012-04-20
| | | | Fixes jittery video playback of rm files with cook audio.
* avio: make AVIOContext.av_class pointer to constMans Rullgard2012-04-18
| | | | | | | | | | Fix this warning: libavformat/aviobuf.c:663:20: warning: assignment discards qualifiers from pointer target type Although this is a public header, it should remain source and binary compatible. Signed-off-by: Mans Rullgard <mans@mansr.com>

* matroska: do not set invalid default duration if frame rate is zeroMans Rullgard2012-04-18
| | | | | | | | | If a video track specifies a zero frame rate (invalid but occurs), this results in a division by zero and subsequent undefined conversion to integer. Setting the default duration from the frame rate only if the latter is greater than zero avoids such problems. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mkv: use av_reduce instead of av_d2q for framerate estimationLuca Barbato2012-04-17
| | | | It avoids some rounding errors.
* mkv: report average framerate as minimal as wellLuca Barbato2012-04-17
| | | | | This is in line with other demuxers and overall seems more correct than assuming codec time base.
* riff: use bps instead of bits_per_coded_sample in the WAVEFORMATEXTENSIBLE ↵Justin Ruggles2012-04-17
| | | | | | | header This matches the value for the plain WAVEFORMATEX header. Also fixes stream copy to WAVE for non-16-bit raw pcm.
* rtmp: Support 'rtmp_playpath', an option which overrides the stream identifierSamuel Pitoiset2012-04-16
| | | | | | | | | This option is the stream identifier to play or to publish. Sometimes the URL parser cannot determine the correct playpath automatically, so it must be given explicitly using this option (ie. -rtmp_playpath). Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmp: Support 'rtmp_app', an option which overrides the name of applicationSamuel Pitoiset2012-04-16
| | | | | | | | This option is the name of application to connect on the RTMP server. Sometimes the URL parser cannot determine the app name automatically, so it must be given explicitly using this option (ie. -rtmp_app). Signed-off-by: Martin Storsjö <martin@martin.st>

* mov: fix leaking memory with multiple drefs.Dale Curtis2012-04-14
| | | | | | | | | Instead of allocating over the original, free first. MOVStreamContext is zero initialized so no double free will occur. Same style as other fixes for the same problem in this file.
