* h264: 4:2:2 intra decoding supportBaptiste Coudurier2011-10-21

* 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().

* 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.

* 4:4:4 H.264 decoding supportJason Garrett-Glaser2011-06-13
| | | | Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.

* Add support for higher QP values in h264.Oskar Arvidsson2011-05-10
| | | | | | | | In high bit depth, the QP values may now be up to (51 + 6*(bit_depth-8)). Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

* H.264 decode: support cropping up to 28 pixels in interlaced mode.Reimar Döffinger2010-11-03
| | | | | | | | Contrary to progressive, just being able to crop up to 14/15 pixels is not enough to encode all supported resolutions, and the new behaviour is also consistent with e.g. MPEG-2 etc. Originally committed as revision 25669 to svn://svn.ffmpeg.org/ffmpeg/trunk
