2012-04-14COMMON: Replaced static Sine and Cosine tables with dynamic generated.D G Turner
This removes the large static tables from the binary (which saves 500K to 1Mb of binary size) and replaced them with a class which generates the required tables as needed in RAM. This has been tested with QDM2 and shows no obvious performance degredation and Memprof shows no significant rise in RAM usage.
2012-04-13COMMON: Minor reduction of sine/cosine table size (8 bytes...).D G Turner
2012-04-13COMMON: Fixes for compiling without USE_BINK enabled.D G Turner
The math utility classes in Common are now used by more than just Bink Video i.e. Huffman is used by SVQ1, RDFT by QDM2 etc. so need to remove conditional inclusion of objects in the Common Library. This was done as these functions are very large wrt. binary size. This is mainly due to the sine, cosine and log tables which should be reconsidered as to whether these are needed or can be replaced by standard sin()/cos() calls.
2012-04-13AUDIO: Remove now unused Sin/Cos table and FFT code from QDM2 Codec.D G Turner
This was only used by the RDFT code, now replaced by Common::RDFT.
2012-04-13AUDIO: Migrate QDM2 Codec to using Common::RDFT class.D G Turner
2012-04-13AUDIO: Fixes to restore QDM2 Codec function.D G Turner
The Bitstream format is changed to 32LELSB and an error in the getVlc2() function bitstream reading needed to be corrected to fix operation.
2012-04-13AUDIO: Update to QDM2 codec fixing pointer to stream buffer usage.D G Turner
This should allow the QDM2 codec to work again with Common::Bitstream instead of the older getBits() reader, but this aborts with a reading past end of stream error...
2012-04-13AUDIO: Removed qdm2_decode_sub_packet_header() function from QDM2.D G Turner
This is to allow modification of the code which needs to assign the data member of the sub_packet structure to an offset in the input byte readStream.
2012-04-13AUDIO: Fix skipping in QDM2 BitStream usage.D G Turner
getBits(n) would cause a runtime error if n is greater than 32, but using getBits() to skip is no longer necessary as the newer BitStream class has a skip method, which is used instead.
2012-04-13AUDIO: Clean up QDM2 getVlc2() function.D G Turner
2012-04-13AUDIO: Initial Refactoring of QDM2 to use Common::BitStream.D G Turner
This removes the internal getBitContext bitwise reading code and replaces with Common::BitStream. However, this breaks the codec as in one location, the internal buffer of getBitContext reader is used and this can't be directly replaced. This will need to be understood and rewritten.

2012-04-10AUDIO: Force QuickTime stereo samples to mono if neededMatthew Hoops
The number of channels in AAC can differ from the actual number of channels needed making us require this. The channel count inside the container is always the correct one.

2012-04-08MOHAWK: Enable the SVQ1 intro for Myst ME MacMatthew Hoops
2012-04-08VIDEO: Minor update to SVQ1 decoder, reversing sense of return flags.D G Turner
This changes the decoder function return flag meaning from "result error" to "resultValid". This makes it more consistent with normal C standard of returning 0 on success.
2012-04-08VIDEO: Fix SVQ1 plane pitchMatthew Hoops
All the Myst intro videos now decode correctly
2012-04-08VIDEO: Minor updates to SVQ1 decoder, mainly return flags to bool.D G Turner
Since the returned int values from the decoding functions are just 0 for good or -1 for error, have changed these into an errorFlag bool. This improves readability and cleans up some of the error checking code. In addition, have fixed some oversights in formatting spacing for readability.
2012-04-08VIDEO: Change SVQ1 decoder to skip rather than decode embedded string.D G Turner
This string field is not used and this avoids having to include a xor table.

2012-04-08VIDEO: Add Missing Half-Pel Motion Compensation Code to SVQ1 Codec.D G Turner
Graphics output is now _almost_ correct.
2012-04-08VIDEO: Rework SVQ1 codebooks so they're endian-safeMatthew Hoops
2012-04-08VIDEO: Workaround for out of buffer accesses in SVQ1 codec.D G Turner
This is a temporary workaround during development. Keyframe (I) decoding is now working correctly, but Deltaframe (P) is still giving corrupted output...
2012-04-08VIDEO: Correct delete type in SVQ1 decoder.D G Turner
2012-04-08VIDEO: Correct SVQ1 Header Decoding and Last Frame Buffering.D G Turner
Header was incorrectly documnented in reference documents. Corrected with reference to FFMPEG. Also, added missing buffering of last frame for P frame decoding.

2012-04-08VIDEO: Add remaining SVQ1 code derived from FFMPEG.D G Turner
This still requires some work to make it usuable, mainly changing the Variable Length Code reader to work with Common::BitStream input.
2012-04-08VIDEO: Corrected minor mistake in SVQ1 decoder.D G Turner
2012-04-08VIDEO: Update SVQ1 WIP with minor corrections.D G Turner
This mainly fixes the Bitstream to Big Endian, MSB to LSB.

2012-04-08VIDEO: Add initial framework and data tables for Sorenson SVQ1 decoder.D G Turner
This is based on the SVQ1 decoder from FFMPEG.

Thanks to clone2727 for these.
