* h264: do not call field_end if we do not have a current pictureAnton Khirnov2014-01-18
| | | | | | | Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* h264: limit allowed pred modes in ff_h264_check_intra_pred_mode() to 3Anton Khirnov2014-01-18
| | | | | | | | | | Higher modes are not allowed for 16x16/chroma, which is what this function is used for. Otherwise this function would return 0 (vertical prediction) for invalid higher modes, which could result in invalid reads.

* h264: reset first_field if frame_start() fails for missing refsAnton Khirnov2014-01-18
| | | | | | | | | | In this case we may not have a current frame, while first_field being set implies we do. Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org

* aarch64: h264 chroma motion compensation NEON optimizationsJanne Grunau2014-01-15
| | | | | Since RV40 and VC-1 use almost the same algorithm so optimizations for those two decoders are easy to do and included.
* aarch64: add cpuflags support for NEON and VFPJanne Grunau2014-01-15
| | | | | | | NEON and VFP are currently mandatory for all ARMv8 profiles. Both are handled as extensions as far as cpuflags are concerned. This is consistent with handling x86_64 which always has SSE2, but still handles it as an extension.

* mov: Free an earlier allocated array if allocating a new oneMartin Storsjö2014-01-15
| | | | | | | | | | | It could probably also be considered an error if the pointer isn't null at this point, but then we might risk rejecting some slightly broken files that we might have handled so far.

* mov: Free intermediate arrays in the normal cleanup functionMartin Storsjö2014-01-15
| | | | | | | | | | | | | These arrays are normally freed at the end of mov_read_trak, but make sure they're freed in case mov_read_trak returned early (due to errors) or in case the atoms that allocate arrays are encountered at some other point than within a trak (which we don't have checks against).

* flv: Workaround for buggy Omnia A/XE encoderBenjamin Larsson2014-01-11
| | | | | | | | | The Omnia A/XE encoder writes the explicit extra data incorrectly and wrongly disables parametric stereo. Truncating the extra data by setting the size to 2 works around this. The AAC extra data parser will then only parse the correct parts. Bug-id: 599
