22 /* TODO list :
23 * - handling of palettes
24 * - recording (which input devices ?), a cam recorder ?
25 * - lots of messages still need to be handled (cf FIXME)
26 * - synchronization between audio and video (especially for interleaved
27 * files)
28 * - robustness when reading file can be enhanced
29 * - reimplement the AVI handling part with avifile DLL because
30 * "open @1122334 type avivideo alias a" expects an AVIFile/Stream
31 * and MCI_DGV_SET|STATUS_SPEED maps to Rate/Scale
32 * - some files appear to have more than one audio stream (we only play the
33 * first one)
34 * - some files contain an index of audio/video frame. Better use it,
35 * instead of rebuilding it (AVIFile does that already)
36 * - stopping while playing a file with sound blocks until all buffered
37 * audio is played... still should be stopped ASAP
