| ** 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.

It looks like QuickTime does this too. | | ** 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).

| * 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. |

|
| === 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.
