Patch originally by the Multicoreware Inc team, followed by improvements and fixes by Micheal Wootton from AMD Inc,
OpenCL:
This patch implements Bicubic Scaling in OpenCL.
Note that HandBrake currently uses Lanczos so the performance difference appears to be much more significant. We may offer an option of BiCubic in software later.
Bicubic scaling may appear a bit sharper than the equivalent Lanczos encode and may increase file size a bit. Quality may be better or worse depending on the scaling and content and personal preference towards sharpness.
When comparing performance with a custom HandBrake build that runs Software Bicubic to OpenCL Bicubic, performance increase is about 5~7% on average on a modern GPU.
Hardware Decode via DXVA:
We also have optional DXVA decoding which may come in useful for slower/lower end systems that have a capable GPU.
This is only available on input sources that use the libav decode path.
Most GPU hardware for decoding is designed for playback, so if you are running on a high end CPU, it will bottleneck the encode process.
Requires OpenCL 1.1 or later supporting GPU.
Front end changes and testing framework are not included in this patch. This will be resolved later.
Patch will be revised further before the UI is implemented.

- encavcodecaudio: use libavresample directly (instead of via the hb_audio_resample wrapper), and add support for planar output
- hb_audio_resample: add support for planar input
- hb_audio_remap: add support for planar input
- deca52: output planar float samples (no re-interleaving)

liba52.
Add support for center & surround mix levels to hb_audio_resample.
This allows us to support upmixing all audio sources. For sources that have at least 2 front and one back or side channel(s), allow upmixing to 5.1:
3.0/3.1 (2 front and 1 back channels)
4.0/4.1 (3 front and 1 back channels)
4.0/4.1 (2 front and 2 side channels)
5.0 (3 front and 2 side channels)

Resolves several deprecated api's

Eliminates our builtin downmix in favour of avresample
Eliminate HB_INPUT_CH_LAYOUT_* and replace with AV_CH_LAYOUT_*

Adds downmix support to declpcm. We never had it!

doing it wrong in some cases.
This means Dolby Pro Logic II is now only available for sources with at least L, R, C, Ls, Rs channels (as well as any additional channels), due to some libdca limitations. This will eventually go away when we use our own downmixing for all sources.
Further cleanup to follow.
Also cleans up usage of audio->config.in.flags (was audio->config.flags.*).

sync needs the precise duration of a frame of audio and has
no way to compute it for passthru audio. So add a duration
member to hb_buffer_t and set it in the audio decoders.
This should eventually supersede hb_buffer_t member "stop"
since it provides redundant information.

This patch enhances the filter objects. The 2 key improvements are:
1. A filter can change the image dimensions as frames pass through it.
2. A filter can output more than one frame.
In addition, I have:
Moved cropping & scalling into a filter object
Added 90 degree rotation to the rotate filter
Moved subtitle burn-in rendering to a filter object.
Moved VFR/CFR handling into a framerate shaping filter object.
Removed render.c since all it's responsibilities got moved to filters.
Improves VOBSUB and SSA subtitle handling. Allows subtitle animations.
SSA karaoke support.
My apologies in advance if anything breaks ;)

adds aac and mp3 passthru for mp4 and mkv containers
adds dts and dtshd for mp4 container (mkv already had it)
Note: The only player known (to me) to support dts(hd) in mp4 is ff/avplay
In LinGui there is a new option to limit which passthru codecs
will be used by the "Auto Passthru" audio codec options. The CLI
already has this ability with "--audio_copy-mask" which is use
in conjunction with the "copy" audio codec option.
Also corrects some A/V sync issues when video frames are dropped due to
a gap detected in the audio.

...from float [-32768...32767] to float [-1.0...1.0]
Using the range [-1.0..1.0] requires fewer translations of the range for our
various encoders and decoders. This also gets rid of a hacky
translation from float to int to float in decavcodec audio decoding.

enable mono mode in lame encoder when mixdown is mono.
use lame_encode_buffer_float instead of lame_encode_buffer_interleave. this
eliminates the clipping issue in lame without reducing the level of the input.

The lame codec has a more limited input range than the other codecs. So
tell the downmixers to stay strictly within the level range requested.

For the moment, presets and interfaces still assume a default of 1, but the notion is to move to having 0 as the default, in the hope it will be louder/clearer.

crc) rather than looking at multiple frames. This should reduce the probability of mis-identifying random junk as AC-3 to less than 1 in 2^32.
- check the crc on every frame so we don't let corrupted data into the decoder.
- interpret the PTS as per the standard (it's the time of the first frame that starts in the packet, not the time of the first byte of the packet). Incorrect interpretation was resulting in an average 15ms timing error (worse case 31ms).
- do all the PTS calculations in doubles so we don't get round-off error that will desync the audio & video with 44.1KHz audio sources (these can't appear on DVDs but do show up in avi/mkv/... files).
- don't rely on the container to give us large enough frame fragments to validate the sync (some containers split audio frames into really small pieces). Instead use the 8K of unused space in the esconfig of the audio object as an accumulation buffer.

pieces so we don't get jerky output caused by out-of-order frames.
- add an explicit EOF for all streams, not just video.
- don't generate extra audio silence at the end of an encode (don't need it with explicit eof).
- get rid of 80ms initial delay in AAC encode & flush final four frames buffered in encoder.
- put mp4 'chap' atom on first track (usually video) rather than first audio track since we can now do video without audio (atom just needs to go on an enabled media track & video is always enabled).

I haven't yet added any code to Controller.mm to recognise the DTS streams as supporting mono / 6ch DPL1 / DPL2 downmixes.
Note: running Jam on the new library required me to update some tools on Mac OS X - possibly libtool, autoconf, automake. Not sure which made the difference, but these were the ones I updated. it won't jam successfully without this.

*NOT YET ADDED TO THE GUI*. Handbrake now uses a more general "audio mixdown" concept. For each audio track to be converted you specify a mixdown. These are defined in common.h.
This checkin only allows you to specify one mixdown for all tracks in the CLI, although everything is in place internally to specify a different mixdown per track. In the CLI, the "-6 --surround" option has been repurposed as a "-6 --mixdown" option, with a string parameter of mono/stereo/dpl1/dpl2/6ch.
