Hello,
This message is largely for Chris Morgan's review, but I thought I
should open it to any interested parties.
I have added wave-in support for arts. I also fixed some bugs in the
waveout code, and made some "improvements". This code seems to work
really well for me. If no one sees any problems I will submit the
patch to the patches mailing list.
Here is a brief description of the changes I made:
(1) In ARTS_CloseDevice() (now named ARTS_CloseWaveOutDevice()) and
wodPlayer_NotifyWait()
I added 'wwo->sound_buffer = 0' after the HeapFree(). Without it,
HeapFree() was being called twice on the same buffer, and would crash
the second time.
(2) ARTS_AddRingMessage()
Added the same fix I submitted earlier for wineoss in regards to ring
buffer resizing.
(3) wodPlayer_WriteMaxFrags()
DWORD *bytes, points to the number of bytes the winearts driver thinks
it should be able to write. However, arts sometimes lies, and says it
has (for example) 512 bytes available, but when you call arts_write()
it returns zero bytes written.
In that case, I update *bytes to point to 0, otherwise
wodPlayer_WriteMaxFrags() will keep being called in vain.
(4a) wodPlayer_FeedDSP()
The old code had the following checks:
/* input queue empty and output buffer with no space */
if (!wwo->lpPlayPtr && availInQ) {
TRACE("Run out of wavehdr:s... flushing\n");
wwo->dwPlayedTotal = wwo->dwWrittenTotal;
return INFINITE;
}
if(!availInQ)
{
TRACE("no more room, no need to try to feed\n");
return wodPlayer_DSPWait(wwo);
}
I could not understand the purpose of the '&& availInQ' in the first
check. It seems that if we are out of wavehdrs, then it does not
matter if there is space in the availInQ or not, because we don't have
anything to write. So I removed the && availInQ part.
Looking at it now, I realize that maybe I need to add 'if (!availInQ)'
before 'wwo->dwPlayedTotal = wwo->dwWrittenTotal'?
(4b) wodPlayer_FeedDSP()
In the while loop, I could not figure out the purpose of 'availInQ >
SPACE_THRESHOLD', so I changed it to 'availInQ'. In reality, the
SPACE_THRESHOLD check could probably be left in, I am not sure what
the purpose was in the first place.
(4c) wodPlayer_FeedDSP()
the while loop in wodPlayer_FeedDSP() can terminate for two reasons:
+ availInQ == 0
+ ran out of waveHdrs to write.
In the first case, wodPlayer_FeedDSP() should return the number of
milliseconds before the buffer needs more data (which it currently
does). In the second case, it should return INFINTE, since it can't
feed anymore data until it gets some more wave headers. I added a bit
of code to handle the second case.
Notice also, that DSPWait() will only be called when the availInQ ==
0. This means that DSPWait() is always calculating the same value
which leads us to 4d.
(4d) Removed wodPlayer_DSPWait()
I just calculate the wait value once in wodOpen() and store it in
wwo->dwSleepTime.
(5) wodOpen ()
In wodOpen I changed the code from setting the ARTS_P_BUFFER_SIZE, to
setting the ARTS_P_PACKET_SETTINGS. This allows for finer control
which I needed in order to achieve lower latency.
The rest of the changes are for adding wave in support.
Jeremy Shaw.
