* swscale: enforce a minimum filtersize.Ronald S. Bultje2012-02-11
| | | | | | | | | | | At very small dimensions, this calculation could lead to zero-sized filters, which leads to uninitialized output, zero-sized allocations, loop overflows in SIMD that uses do{..}while(i++<filtersize); instead of for(i=0;i<filtersize;i++){..} and several other similar failures. Therefore, require a minimum filtersize of 1. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* alacenc: cosmetics: indentationJustin Ruggles2012-02-11
|
* alacenc: consolidate bitstream writing into a single function.Justin Ruggles2012-02-11
| | | | Simplifies use of verbatim mode.
* alacenc: only encode frame size in header for a final smaller frameJustin Ruggles2012-02-11
| | | | | Otherwise it is not needed because it matches the frame size as encoded in the extradata.
* alacenc: store current frame size in AlacEncodeContext.Justin Ruggles2012-02-11
| | | | This avoids an indirection and will simplify implementation of encode2()
* alacenc: return AVERROR codes in alac_encode_frame()Justin Ruggles2012-02-11
|
* alacenc: calculate a new max frame size for the final small frameJustin Ruggles2012-02-11
| | | | | Gives a better estimate of buffer requirements and a better decision of whether or not to use verbatim mode.

* alacenc: do not set coded_frame->key_frameJustin Ruggles2012-02-11
| | | | It is already set in avcodec_alloc_frame()
* alacenc: do not set bits_per_coded_sampleJustin Ruggles2012-02-11
| | | | encoded ALAC does not have a fixed number of bits per sample

* h264: disallow constrained intra prediction modes for luma.Ronald S. Bultje2012-02-09
| | | | | | | | | | | Conversion of the luma intra prediction mode to one of the constrained ("alzheimer") ones can happen by crafting special bitstreams, causing a crash because we'll call a NULL function pointer for 16x16 block intra prediction, since constrained intra prediction functions are only implemented for chroma (8x8 blocks).

* ac3dsp: do not use pshufb in ac3_extract_exponents_ssse3()Justin Ruggles2012-02-09
| | | | | | | We need to do unsigned saturation in order to cover the corner case when the absolute coefficient value is 16777215 (the maximum value). Fixes Bug #216
* ac3dec: Move center and surround mix level tables to the parser.Michael Niedermayer2012-02-09
| | | | | | | | | | | | That way all mix levels as exported by avpriv_ac3_parse_header() will have the same meaning. Previously the 3-bit center mix level for E-AC-3 was used to index in a 4-entry table, leading to out-of-array reads.
