* webp: ensure that each transform is only used onceAndreas Cadhalpun2015-03-19
| | | | | | | | | | | According to the WebP Lossless Bitstream Specification "each transform is allowed to be used only once". If a transform is more than once this can lead to memory corruption.

* mjpeg: Mark decoder family as thread safeVittorio Giovara2015-03-13
| | | | | | No global variables are used and the VLC tables are allocated without static elements. This will allow using a JPEG decoding context within other decoders.
* lavc: Introduce AVCodec internal capabilitiesVittorio Giovara2015-03-13
| | | | | | | This field is designed for marking codec properties useful to lavc internals. Two internal capabilities are added: - FF_CODEC_CAP_INIT_THREADSAFE: codec can be opened without locks; - FF_CODEC_CAP_INIT_CLEANUP: codec frees memory if initialization fails.

* roqvideoenc: set enc->avctx in roq_encode_initAndreas Cadhalpun2015-03-11
| | | | | | | | | | | So far it is only set in roq_encode_frame, but it is used in roq_encode_end to free the coded_frame. This currently segfaults if roq_encode_frame is not called between roq_encode_init and roq_encode_end.

| | | | | | | | | The fourth substream is being discarded, since its not raw audio data, but an encoded Atmos stream which needs a specialized decoder.

* vorbis: Check the vlc value in setup_classifsLuca Barbato2015-03-08

* webp: validate the distance prefix codeAndreas Cadhalpun2015-03-05
| | | | | | | | | | | According to the WebP Lossless Bitstream Specification the highest allowed value for a prefix code is 39. If prefix_code is too large, the calculated extra_bits has an invalid value and triggers an assertion in get_bits.

* aac: Relax reserved_bit validationVittorio Giovara2015-03-04
| | | | | | | | | | | Although the specification mandates this bit to zero, it may happen that software tools incorrectly flip it to one, invalidating a possibly valid stream. Relax this restriction, by failing only when AV_EF_BITSTREAM is set. This behaviour is similar to aac decoders in Firefox and Quicktime. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* wma.h: #include "avcodec.h"Anton Khirnov2015-03-03
| | | | | | It's required for at least AVCodecContext. Fixes make checkheaders.
* aic: Fix decoding files with odd dimensionsVittorio Giovara2015-03-03
| | | | | | | | | Normally the aic decoder finds the proper slice combination (multiple of some number less than 32) but in case of odd width, it resorts to the default values, which were actually swapped. The number of slices is modified to account for such odd width cases. CC: libav-stable@libav.org
* prores: Extend the padding check to 16bitLuca Barbato2015-03-02
| | | | | | | | | | | Some files produced by the official encoder have up to 16bit of padding instead of the expected padding to the byte. Use a self-explanatory macro instead of a simple number. CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
