This feature allows making associations between audio tracks that apple players recognize. E.g. when an ac3 track has a tref that points to an aac track, devices that don't support ac3 will automatically fall back to the aac track. Apple used to *guess* these associations, but new products (AppleTV 4) no longer guess and this association can only be made explicitly now using the "fall" tref.

This side data type is meant to be added to AVStream side data. A fallback track indicates an alternate track to use when the current track can not be decoded for some reason. e.g. no decoder available for codec. Signed-off-by: Anton Khirnov <anton@khirnov.net>

FFv1 uses two types of coders, golomb and range with two different tables. This is exposed this in a rather convoluted way, for example mentioning to set coder type 1 while initializing the variable 'ac' to 2, because encoder does not use range coder with default table. Appropriate internal coder type values have been added and used in any check rather than using raw numbers. Initialization of avctx.coder_type in ffv1dec is removed because this field is encoder only. An unneeded validation check in the encoder is dropped too.

It is used as size argument of ff_canopus_parse_info_tag, which uses it as size argument to bytestream2_init, which only supports sizes up to INT_MAX. Changing it's type to unsigned simplifies the check. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>

The XTEA algorithm operates on 32 bit numbers, not on byte sequences. The XTEA implementation in libavutil is written assuming big endian numbers, while the rtmpe signature encryption assumes little endian. This fixes rtmpe communication with rtmpe servers that use signature type 8 (XTEA), e.g. crunchyroll. Signed-off-by: Martin Storsjö <martin@martin.st>

Some entries might be either empty or contain types we do not parse (eg. 'url '). In both cases, if an 'alis' is not the first entry, external references are not loaded, so make sure that the array starts with an 'alis' dref.

Rather than reading the alternate absolute path version from dref type 18, make sure that 0s are considered as '/'. These values are sometimes present in the full path, and are mistakenly interpreted as line terminators othewise. With the correct handling of this dref type, parsing type 18 is not needed any more.

By writing a zero-sized packet, the caller can communicate the start_dts/start_cts for the stream without actually writing the first packet. This allows doing random-access writing of fragments when the start dts of the stream isn't zero, so that the edit list in the moov is written based on timestamps from the nominal start time signaled via the zero-sized packet, while the first proper packet written corresponds to a later fragment. To avoid potential unexpected behaviour, empty packets only set start_dts if the frag_discont flag is set. Signed-off-by: Martin Storsjö <martin@martin.st>

Contrary to the normal fate tests that run via avconv, this tests nontrivial call sequences that are only doable via the API (mainly for different corner cases when using the muxer for segmenting). The test muxes fake packet data (with extradata that looks enough like proper data to make the file be viewable with e.g. boxdumper) and checks the hash of the produced files. The test also verifies that fragments produced via different call sequences remain identical (to avoid e.g. updating the output hashes and suddenly having fragments that used to be identical suddenly diverging), for fragments written with frag_discont and/or delay_moov.

In most other cases when writing fragmented mp4 files, the output IO context is flushed after each fragment. Also flush it after writing the initial moov, to have it behave in the same way. Signed-off-by: Martin Storsjö <martin@martin.st>
