Audio stops after the bytes in the first BASS_StreamPutData are used. I have: BASS_ChannelPlay(chan,false), so subsequent BASS_StreamPutData should continue to play, right?

BASS_ChannelGetData(chan, outbuf, BASS_DATA_AVAILABLE); shows there is data available but the audio stops.

[Ian @ un4seen]

What does BASS_ChannelIsActive say about the "chan" channel's status at that point? Please also check what values BASS_StreamPutData is returning, eg. is it increasing with each call as more data is queued up?

Looks like the return value from put is not incrementing properly.

Looks like I had the printf format wrong on the bytes in and return for the put:

So the put is failing. What does BASS_ERROR_ENDED mean?

[dts350z]

And why is the first put returning more bytes than I told it to put?

[dts350z]

OK I got it working. Thanks.

Still don't understand why the returned byte from put is more than I told it to put.

[Ian @ un4seen]

So the put is failing. What does BASS_ERROR_ENDED mean?

BASS_ERROR_ENDED would result when the BASS_STREAMPROC_END flag (which marks the end of the data) has been used in a previous BASS_StreamPutData call.

Still don't understand why the returned byte from put is more than I told it to put.

The only explanation that comes to mind is that there is data queued from a previous BASS_StreamPutData call. Is that not the case? Note BASS_StreamPutData returns the total amount of data that is currently queued, not only the amount from the current call.

[dts350z]

It happens on the first put call too. Would the extra bytes represent the latency between starting play and the first put call?

[Ian @ un4seen]

No, the BASS_StreamPutData return value won't be related to latency. Looking at your log above, is "Read" what you passed in the BASS_StreamPutData "length" parameter? If so, the return value doesn't actually appear to be higher, ie. 15787804 is lower than 15876000.

[dts350z]

I stand corrected.

Thanks.
