2017-06-30VIDEO: Refactor AVIDecoder for better handling of transparency trackPaul Gilbert
A lot of the standard VideoDecoder methods were still treating the transparency track as part of the video, so methods like getFrameCount would return double the amount it should be. This refactoring properly separates the transparency track into a separate field entirely.

2017-06-17VIDEO: Wrap out-of-range VMD audio samples instead of clippingColin Snover
The 16-bit DPCM decompressors in SSCI and Urban Runner use a 16-bit register to store sample data, without any special handling of overflow. As such, out-of-range samples simply wrap around, rather than getting clipped. It is not totally clear if the wrapping behaviour was intentionally exploited to handle extreme transients, but in any case, videos like GK2 5280.VMD that generate samples outside the signed 16-bit range cause a loud pop when using clipping, but play back correctly when wrapping.
2017-04-29VIDEO: Unexpose audio sync API in AdvancedVMDDecoderColin Snover
This change was inadvertently added in commit 44dd029cb17160316b2015321a0a53f8854b6dd3 but is not actually used.

This gives Indeo3 the same behavior as other codecs when encapsulated in a container that provides bit depth information (e.g. AVI). Closes #888.

2016-12-29VIDEO: Further work on 2-track AVI videosPaul Gilbert
It turns out that at least one video in Starship Titanic, for the Lift Indicator, has only a single transparency frame in track 2. The added code, therefore, when it doesn't find an index entry for the desired frame number, works backwards until it finds a valid frame (likely frame 0), and then scans forward. If it hits the end of the video, then it simply uses whatever last frame it last decoded.

2016-07-17VIDEO: Add support for a track filtering callback functionPaul Gilbert
This is needed for Starship Titanic, where videos can have a secondary video track. It was simpler to use the callback as a means to select one video track each across two decoders than trying to make VideoDecoder and/or AVIDecoder support decoding from multiple video tracks simultaneously
2016-07-15VIDEO: Respect RIFF filesize field when decoding AVI filesPaul Gilbert
Starship Titanic in particular needs this, since some of the videos have extra junk at the end of the file, such as ycursors.avi, and parsing fails if we don't respect the filesize field
2016-07-10VIDEO: Expose API for providing a memory location to draw VMDsColin Snover
In SSCI, VMD is drawn by a standard CelObjMem wrapped by a ScreenItem, giving the location of the bitmap memory to the decoder. The decoder already supports this, but the API was previously hidden behind the AdvancedVMDDecoder wrapper (which is more convenient to use than the VMDDecoder class).

2016-02-13VIDEO: Stay on the first edit when playing QT videos backwardsBastien Bouclet
We don't support playing videos with multiple edits backwards. Taking the code path to move to the next edit when playing backwards sets the current edit index to an invalid value with the video still trying to play. Which results in out of bounds reads, and ultimately a crash. This fixes multiple crashes in Myst. Using the key without the chest on Stoneship, resetting the clock tower puzzle, and using the switch in the trees in Channelwood. This was a regression introduced in a59f5db505ffce9567c3bc8adf30d2f843910d65.

If seeking to the final frame of an edit, _nextFrameStartTime wouldn't be adjust properly and would wrongly say that it's at the end of the edit. This never affected anything because of the edit "-1" hack.
