* 4xm: replace forcing EMU_EDGE by a copyAnton Khirnov2014-01-06
| | | | | | | | | | | The decoder currently sets CODEC_FLAG_EMU_EDGE and relies on get_buffer2() to always provide buffers with linesize == 2 * width. This is wrong, since we place no such restriction on get_buffer2() implementations. Fix this by decoding into internal buffers and copying them to output frames. Since this is a very obscure decoder, the performance hit should not be an issue.

* dcadec: set the output channel mode more accurately.Tim Walker2014-01-05
| | | | | | When downmixing 2.1 to 2-channel, if the 2.0 portion is Lt/Rt, sum-difference or dual mono, the actual output will be the same (with the LFE either mixed-in or discarded). Also, when downmixing an arbitrary layout to 2-channel, if the bitstream contains custom downmix coefficients targeting Lt/Rt, then the output will be Lt/Rt rather than regular Stereo.

* h264: reset data_partitioning if decoding the slice header for NAL_DPA failsAnton Khirnov2014-01-03
| | | | | | | | If it was set before then we can end up trying to decode a slice without a valid slice header, which can lead to invalid memory access. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org

* mpegvideo: set reference/pict_type on generated reference framesAnton Khirnov2014-01-03
| | | | | | | | | Otherwise the generic code will unref them, which can then result in last_picture_ptr == current_picture_ptr, which causes deadlocks at least in rv40. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org

* png_parser: Fix parsing on big endianMartin Storsjö2013-12-18
| | | | | | | | | | | | Since pc.state is populated by shifting in from the end of the 32 bit word, the content within pc.state is already in native endian and should not be read with the AV_R{L,B} functions. This was already done correctly for state64 above. This fixes the fate-corepng test on big endian. Signed-off-by: Martin Storsjö <martin@martin.st>
