* sgienc: Use a local RLE encoding functionVittorio Giovara2015-11-243-17/+54
| | | | | | SGI RLE encoding is slighlty different than the one provided by rle module (especially at high bit depth). The pixel count function however does not change, so it is simply made library-public.

* asfdec: handle the case when the stream index has an invalid value betterAlexandra Hájková2015-11-231-3/+17
| | | | | | | | | | The demuxer returned INVALIDDATA and failed to demux the remaining data when an invalid stream index was read, now it just skips the asf packet for the stream with an invalid stream index and continues demuxing.

* dcadec: Do not check for overreads in auxiliary dataTim Walker2015-11-231-6/+6

* configure: Clearly state that MSYS native builds are discouragedLuca Barbato2015-11-211-0/+3
| | | | | | | | | MSYS, as per cygwin, by default uses a custom posix abstraction in the form of a "msys2.dll". Programs build that way are harder to distribute and use. MSYS2 provides alternate launcher scripts that provide a MINGW environment nearly out of box.
* lavc: Deprecate avctx.rtp_callback fieldVittorio Giovara2015-11-204-1/+23
| | | | | | | | | | | | | | | | | | | | | This function returns the encoded data of a frame, one slice at a time directly when that slice is encoded, instead of waiting for the full frame to be done. However this field has a debatable usefulness, since it looks like it is just a convoluted way to get data at lowest possible latency, or a somewhat hacky way to store h263 in RFC-2190 rtp encapsulation. Moreover when multi-threading is enabled (which is by default) the order of returned slices is not deterministic at all, making the use of this function not reliable at all (or at the very least, more complicated than it should be). So, for the reasons stated above, and being used by only a single encoder family (mpegvideo), this field is deemed unnecessary, overcomplicated, and not really belonging to libavcodec. Libavformat features a complete implementation of RFC-2190, for any other case. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* movenc: add fallback audio track tref supportJohn Stebbins2015-11-181-4/+15
| | | | | | | | | | | | | 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.

* avcodec: Define side data type for fallback trackJohn Stebbins2015-11-183-1/+13
| | | | | | | | | 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: Explicitly name the coder typeVittorio Giovara2015-11-164-29/+27
| | | | | | | | | | | | | | | | 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>
