- Moved the identical code between the MUS and MIDI streamers into a new base
class so they all the low-level details of MIDI streaming are kept in one place. - Converted the SMF MIDI playback to use the same MIDI streams as MUS playback. - Moved MUS playback back into its own thread so that it can continue uninterrupted if the main thread is too busy to service it in a timely manner. - Fixed: The MEVT_* values are not defined shifted into their spot for a MIDIEVENT, so I need to do it myself. - Fixed: Pausing a MUS and the changing snd_midivolume caused the paused notes to become audible.

- Moved the identical code between the MUS and MIDI streamers into a new base
|
||||
class so they all the low-level details of MIDI streaming are kept in
|
||||
one place.
|
||||
- Converted the SMF MIDI playback to use the same MIDI streams as MUS
|
||||
playback.
|
||||
- Moved MUS playback back into its own thread so that it can continue
|
||||
uninterrupted if the main thread is too busy to service it in a timely
|
||||
manner.
|
||||
- Fixed: The MEVT_* values are not defined shifted into their spot for a
|
||||
MIDIEVENT, so I need to do it myself.
|
||||
- Fixed: Pausing a MUS and the changing snd_midivolume caused the paused
|
||||
notes to become audible.
|
||||
|
||||
March 3, 2008
|
||||
- Changed MUS playback to use MIDI streams, like it did during the early days
|
||||
of ZDoom, except now the entire song isn't prebuffered in large chunks, so
|
||||
I can insert MIDI events into the playback with fairly low latency. This
|
||||
should offer more precise timing than the combination of low-level MIDI and
|
||||
WaitForSingleObject timeouts.
|
||||
WaitForMultipleObjects timeouts that it replaces.
|
||||
- Fixed: PTR_BounceTraverse only checked for projectiles that were too
|
||||
high to pass through two-sided lines, but not ones that were too low.
|
||||
- Fixed: SBARINFO couldn't detect the extreme death damage type for the
