Mike Melanson	9d8bb0318a	Small refactoring: Instead of 4 loops for decoding AC coefficients based on their grouping, create one loop that indexes into a table of AC VLC tables. There is also a small optimization here: Do not call unpack_vlcs() if there are no fragments in the list with outstanding coefficients. My profiling indicates that this can save upwards of 1 million dezicycles per frame throughout the course of unpack_dct_coeffs().

Mike Melanson	098523eb28	Use a list to track which fragments coded in this frame still have outstanding coefficients yet to be decoded from the bitstream. Once a fragment reaches end-of-block, remove it from this new list. This change makes the VP3/Theora entropy decode process dramatically faster due to not having to iterate incessantly over fragments which have already been fully decoded.

Michael Niedermayer	94f28061f5	Store original width/height so that rv20 does not get stuck with some resolution. A sample file to show a difference is at issue833 (http://airfarce.com/video/000211fh.rm) Originally committed as revision 20691 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	22d4f21331	Make ""MPEG motion vector out of boundary" message more verbose. Originally committed as revision 20669 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Attila Kinali	76c4a644ee	Fix an issue uncovered by commit 20623: The init functions of mpc7 and mpc8 check whether the vlc has been initialized already and return early if this is the case (eg by calling init a second time). But avctx->sample_fmt and channel_layout is set after the vlc initialization, causing it not to be set on the second call of init. Move all manipulations of avctx before the initialization of the vlc, so that it is always set. Originally committed as revision 20668 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
