* tty: set avg_frame_rate.Anton Khirnov2013-03-08
| | | | The container does not store any timestamps and is CFR-only.
* Replace remaining includes of audioconvert.h with channel_layout.hAnton Khirnov2013-03-08

* avpacket: use AVBuffer to allow refcounting the packets.Anton Khirnov2013-03-08
| | | | | | This will allow us to avoid copying the packets in many cases. This breaks ABI.
* mp3dec: Fix VBR bit rate parsingAlexander Kojevnikov2013-03-08
| | | | | | | | | | | | When parsing the Xing/Info tag, don't set the bit rate if it's an Info tag. When parsing the stream, don't override the bit rate if it's already set, otherwise calculate the mean bit rate from parsed frames. This way, the bit rate will be set correctly both for CBR and VBR streams. CC:libav-stable@libav.org Signed-off-by: Anton Khirnov <anton@khirnov.net>
* Use the avstring.h locale-independent character type functionsReimar Döffinger2013-03-07
| | | | | | Make sure the behavior does not change with the locale. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Initialize some variables to silence compiler warningsMartin Storsjö2013-03-02
| | | | | | | | The warnings are false positives, older gcc versions (such as 4.5) think the variables can be used uninitialized while they in practice can't, while newer (4.6) gets it right. Signed-off-by: Martin Storsjö <martin@martin.st>
* flvdec: Check the return value of a mallocMartin Storsjö2013-03-02
| | | | | | | | | | The callers of this function can't report errors sanely. If this one malloc fails, don't write the extradata byte, make sure we try to malloc it the next time we're called instead, and make sure we still consume the input data byte.

* flvdec: Don't read the VP6 header byte when setting codec type based on metadataMartin Storsjö2013-03-02
| | | | | | | | | This header byte is only present when actually reading a VP6 frame, not when reading the codec type field in the metadata. This potential bug has been present since 5b54a90c. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* lavf: Handle the environment variable no_proxy more properlyMartin Storsjö2013-02-27
| | | | | | | | | | | | | | | | | | | | The handling of the environment variable no_proxy, present since one of the initial commits (de6d9b6404), is inconsistent with how many other applications and libraries interpret this variable. Its bare presence does not indicate that the use of proxies should be skipped, but it is some sort of pattern for hosts that does not need using a proxy (e.g. for a local network). As investigated by Rudolf Polzer, different libraries handle this in different ways, some supporting IP address masks, some supporting arbitrary globbing using *, some just checking that the pattern matches the end of the hostname without regard for whether it actually is the right domain or a domain that ends in the same string. This simple logic should be pretty similar to the logic used by lynx and curl. Signed-off-by: Martin Storsjö <martin@martin.st>

* asfdec: do not assume every AVStream has a corresponding ASFStreamAnton Khirnov2013-02-09
| | | | | | | This won't be true for ID3 attached picture. Also stop allocating now useless dummy ASFStreams for ASF native attached pictures.
* asfdec: support reading ID3v2 tags in ASF filesVladimir Pantelic2013-02-09
| | | | | | | Yes, these files do exist Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* asfdec: also read Metadata Library ObjectVladimir Pantelic2013-02-09
| | | | | | | | In some ASF files this objects holds cover art and other tags. Compared to Metadata Object it can also hold GUIDs, but we ignore these for now. Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* asfdec: read the full Metadata Object, not just aspect ratio informationVladimir Pantelic2013-02-09
| | | | | | | | Use the same get_tag()/get_value() as for the Extended Content Description but handle the 16 bit vs 32 bit difference for type 2 (BOOL) Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* mvi: set framerateAnton Khirnov2013-01-29
| | | | This container does not store timestamps and thus supports CFR only.
* rtpenc_chain: Use the original AVFormatContext for getting payload typeMartin Storsjö2013-01-24
| | | | | | | | | | | | | | | | | In ff_rtp_get_payload_type, the AVFormatContext is used for checking whether the payload_type or rtpflags options are set. In rtpenc_chain, the rtpctx struct is a newly initialized struct where no options have been set yet, so no options can be fetched from there. All muxers that internally chain rtp muxers have the "rtpflags" field that allows passing such options on (which is how this worked before 8034130e06), so this works just as intended. This makes it possible to produce H263 in RFC2190 format with chained RTP muxers. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* rtp: Make sure the output format pointer is setMartin Storsjö2013-01-24
| | | | | | | | Not sure if this actually happens, but we do the same check when checking payload_type further above in the function, so it might be needed. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtp: Make sure priv_data is set before reading itMartin Storsjö2013-01-23

* rtpenc: fix overflow checking in avc_mp4_find_startcode()Xi Wang2013-01-23
| | | | | | | | | | | | The check `start + res < start' is broken since pointer overflow is undefined behavior in C. Many compilers such as gcc/clang optimize away this check. Use `res > end - start' instead. Also change `res' to unsigned int to avoid signed left-shift overflow. Signed-off-by: Xi Wang <xi.wang@gmail.com> Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmp: fix buffer overflows in ff_amf_tag_contents()Xi Wang2013-01-23
| | | | | | | | | | | | | | A negative `size' will bypass FFMIN(). In the subsequent memcpy() call, `size' will be considered as a large positive value, leading to a buffer overflow. Change the type of `size' to unsigned int to avoid buffer overflow, and simplify overflow checks accordingly. Also change a literal buffer size to use sizeof, and limit the amount of data copied in another memcpy call as well.

* rtmp: fix multiple broken overflow checksXi Wang2013-01-23
| | | | | | | | | | | | Sanity checks like `data + size >= data_end || data + size < data' are broken, because `data + size < data' assumes pointer overflow, which is undefined behavior in C. Many compilers such as gcc/clang optimize such checks away. Use `size < 0 || size >= data_end - data' instead.

* rtpenc: Start the sequence numbers from a random offsetMartin Storsjö2013-01-22
| | | | | | | | Expose the current sequence number via an AVOption - this can be used both for setting the initial sequence number, or for querying the current number. Signed-off-by: Martin Storsjö <martin@martin.st>
* avidec: use sensible error codes instead of -1Jindrich Makovicka2013-01-21
| | | | | | | | Use AVERROR_INVALIDDATA on invalid inputs, and AVERROR_EOF when no more frames are available in an interleaved AVI. Signed-off-by: Jindrich Makovicka <makovick@gmail.com> Signed-off-by: Diego Biurrun <diego@biurrun.de>

* srtp: Don't require more input data than what actually is neededMartin Storsjö2013-01-21
| | | | | | | | | | The theoretical minimum for a (not totally well formed) RTCP packet is 8 bytes, so we shouldn't require 12 bytes as minimum input. Also return AVERROR_INVALIDDATA instead of 0 if something that is not a proper packet is given. Signed-off-by: Martin Storsjö <martin@martin.st>
* srtp: Improve the minimum encryption buffer size checkMartin Storsjö2013-01-21
| | | | | | | This clarifies where the limit number comes from, and only requires exactly as much padding space as will be needed. Signed-off-by: Martin Storsjö <martin@martin.st>
* srtp: Add support for a few DTLS-SRTP related crypto suitesMartin Storsjö2013-01-21
| | | | | | | | The main difference to the existing suites from RFC 4568 is that the version with a 32 bit HMAC still uses 80 bit HMAC for RTCP packets. Signed-off-by: Martin Storsjö <martin@martin.st>
