* lavc: introduce a new decoding/encoding API with decoupled input/outputwm42016-03-23
| | | | | | | | | | | | | | | | Until now, the decoding API was restricted to outputting 0 or 1 frames per input packet. It also enforces a somewhat rigid dataflow in general. This new API seeks to relax these restrictions by decoupling input and output. Instead of doing a single call on each decode step, which may consume the packet and may produce output, the new API requires the user to send input first, and then ask for output. For now, there are no codecs supporting this API. The API can work with codecs using the old API, and most code added here is to make them interoperate. The reverse is not possible, although for audio it might. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* intrax8: Check and propagate errors from ff_intrax8_common_initVittorio Giovara2016-03-22
| | | | This allows dropping an afterwards redundant assert.

* intrax8: Wrap multiline macros in do{}while(0) clausesVittorio Giovara2016-03-22
| | | | | These macros are treated like functions, the wrapping simplifies error checking and avoids deeply nested ifs in the following commit.
* intrax8: Move error resilience out of intrax8Vittorio Giovara2016-03-22
| | | | | | | | The intrax8 decoding process does not imply any kind of error resilience, and the only call present is more related to how mpegvideo works rather than anything else. Therefore have the parent decoders carry out er when actually needed.
* indeo4: Consistently initialize variablesVittorio Giovara2016-03-22
| | | | Avoid using multiple variables for the same purpose.
* indeo4: Rework stream analysis reportVittorio Giovara2016-03-22
| | | | | | | | * Change log level from error to debug * Print report after the first decoded frame, not at the end of decoding * Drop macro guard and use a context variable instead Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| | | | Deprecate the current bitstream filtering API.
* takdec: ensure chan2 is a valid channel indexAndreas Cadhalpun2016-03-20
| | | | | | | | If chan2 is not smaller than the number of channels, it can cause segmentation faults due to dereferencing a NULL pointer. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* idct8x8: Fix undefined negative shiftsKaterina Barone-Adesi2016-03-05
| | | | | | | | | | | The original code left-shifts negative values, which is undefined in the C99 specification (the one used during normal Libav compilation). This change multiplies by (1 << shift), which is functionally equivalent, but has defined behavior. With this change, fate-idct8x8 compiled with --fsanitize=undefined works. Bug-Id: 686
