* Backwards playback/seeking
** Myst ME:
*** Myst Card 4113: Retracting weight in the clock tower
** Myst Original:
*** Stoneship Card 2138: Chest key animation with no chest present
*** Stoneship Card 2132: Chest valve animation when chest is empty
*** Channelwood Card 3385: Closing stairs upper door animation
* Playback at custom framerates - Needed for Myst Cabin Boiler videos.
* The Cyan logo repeats some frames at the end. I call it "Cyan logo syndrome." This is caused by the lack of handling of multiple edit lists. FFmpeg doesn't handle this yet either.
* Some Cinepak frames have corruption.
* Some Cinepak frames have corruption.
** The Myst linking book video on D'ni has a corrupted Cinepak frame (data-wise). Right now, we just skip that frame (and throw a warning). It looks like QuickTime does this too.

** The CD (but ''not'' the DVD) version of Riven has at least two videos with a corrupt frame: the wood chipper (when power is directed elsewhere) and using the trap book before talking with Gehn (when not on Tay).

* Unify the 8bpp to 16/32bpp code snippets. This is mostly done already. I have a patch to add it to graphics/conversion.h, but still waiting on that one.
* Myst's fortress rotation holo-simulator requires playing QT movies with edit lists backwards. For now this is hacked around in the Mechanical code so that the puzzle works properly.


== Myst TODO ==
== Myst Status ==
The game is playable and should be completable to all four endings, though many issues still need to be fixed.
The game is completable to all four endings.


=== Main TODO ===
=== Known issues ===
* Myst ME support is missing these codecs: QDesign Music 2 (partially working) and Sorenson Video 1.
* Myst ME 10th Anniversary Edition requires Sorenson Video 3 for the UbiSoft logo
* Myst 10th Edition requires the Myst ME codecs plus Sorenson Video 3.
** Since SVQ3 is quite large (and based on h.264), we may suggest the user just take the video from the Macintosh portion of the disc, which is QTRLE
* JPEG Optimization for Myst ME.
* The help system is missing in Myst ME
* Add "Drop Page".
* Add Transitions.
* Myst Demo Only - Add "Return To Main Menu"
* Myst ME Only - Add "Show Map" and Help System.
* Myst Original - Background sound restarts incorrectly compared to original interpreter on a number of cards. <br>Good test case for this is Myst Card 4697 and 4689 (Myst Imager Forechamber Tunnel - Background Music).<br>These play resource Ids 4697 and 4689 from VIEW sound block respectively, which is the same sound, but glitches <br>due to the playback restart. It is probable the original interpreter on new sound playback continues from the <br>same time offset, if this is within the new sound's duration i.e. thus no "seam" is heard.

The game first became completable with r52735. As of r55299, the game is completable with no prior knowledge.
The game first became completable with [https://github.com/scummvm/scummvm/commit/bb5db4a bb5db4a]. As of [https://github.com/scummvm/scummvm/commit/245b733 245b733], the game is completable with no prior knowledge.


=== Main TODO ===
=== Main TODO ===
(In Order of Priority):
* Finish External Commands (Many are done, most are self-explanatory)
* Complete the complexPlayMovie opcode
** Used in a couple places, fairly straightforward, but will involve a new video loop
* Transitions
* Finish ambient sound handling: Only fading is left
* Cleanup video handling, all involve the QuickTime overlay:
** Rarely before a video, the screen that should be shown after the video flashes before the video starts (for example: opening the linking book in the Rebel tunnel puzzle).
** Rarely after a video, the engine does not update with the correct screen. As far as I can tell, this ''only'' affects the easter egg videos on gspit and ospit under normal conditions. However, it can be noticed when skipping a video on occasion.
* Cleanup hotspot debugging mode. The water effect and videos write over it.
* Cleanup hotspot debugging mode. The water effect and videos write over it.
=== Stack TODO/Known Bugs ===
==== gspit (Survey Island - internally Garden) ====
* The underwater viewer is partially implemented.
** xgwharksnd needs to be implemented.
** Has hardcoded background sounds.
==== jspit (Jungle Island) ====
* Missing randomized sunner videos.
** xjlagoon700_alert and xjlagoon800_alert need to be implemented.
** Has hardcoded background videos.
==== tspit (Temple Island) ====
* Marbles not drawn on grid when standing one step back from the marble puzzle
** xt7600_setupmarbles needs to be completed.
