* AVOptions: add new API for enumerating children.Anton Khirnov2011-10-12
| | | | | | | | | This will allow the caller to enumerate child contexts in a generic way and since the API is recursive, it also allows for deeper nesting (e.g. AVFormatContext->AVIOContext->URLContext) This will also allow the new setting/reading API to transparently apply to children contexts.
* rv34: move inverse transform functions to DSP contextJanne Grunau2011-10-12

* h264: change unsupported bit depth message to error levelMans Rullgard2011-10-12
| | | | | | | Unsupported bit depth is certainly an error the user will want to know about. Signed-off-by: Mans Rullgard <mans@mansr.com>
* qdm2: fix signed multiplication overflowMans Rullgard2011-10-12
| | | | | | | | This code relies on the result wrapping as for unsigned values, and the sign is not used. Thus an unsigned type is proper here. Signed-off-by: Mans Rullgard <mans@mansr.com>

* h264: fix HRD parameters parsingMans Rullgard2011-10-11
| | | | | | | | | | The bit_rate_value_minus1 and cpb_size_value_minus1 elements allow a wider range than get_ue_golomb() supports. This adds a get_ue_golomb_long() function supporting up to 31 leading zeros, which is the maximum for these syntax elements, and uses it in decode_hrd_parameters().

* prores: implement multithreading.Ronald S. Bultje2011-10-11
| | | | | 60% speedup (overall decoding time) at 2 threads, and another 60% speedup at 4 threads.
* prores: idct sse2/sse4 optimizations.Ronald S. Bultje2011-10-11
| | | | ~3.0-3.5x as fast as original C version, 1.6x as fast overall.

* h264: fix invalid shifts in init_cavlc_level_tab()Mans Rullgard2011-10-11
| | | | | | | | The level_code expression includes a shift which is invalid in those cases where the value is not used. Moving the calculation to the branch where the result is used avoids these. Signed-off-by: Mans Rullgard <mans@mansr.com>

* h264: fix detection of optional trailing PPS elementsMans Rullgard2011-10-11
| | | | | | | | | | | | | | The PPS may contain a few trailing elements whose presence is only signalled by data remaining after the the mandatory part has been parsed. The current code fails to take into account the rbsp_trailing_bits() when deciding whether to parse these optional elements. Assuming no unnecessary padding bytes are passed to this function, the optional elements are present if either more than 8 extra bits remain or the remaining bits do not form a valid rbsp_trailing_bits() after the mandatory PPS elements have been parsed.

* sipr: fix get_bits(0) callsMans Rullgard2011-10-11
| | | | | | Zero-length get_bits() is undefined, must check before calling. Signed-off-by: Mans Rullgard <mans@mansr.com>
* motion_est: make MotionExtContext.map_generation unsignedMans Rullgard2011-10-11
| | | | | | | | The way this value is used, it should be an unsigned type. While the numerical value has no meaning, unsigned wraparound is relied upon. Signed-off-by: Mans Rullgard <mans@mansr.com>
