Crash in -[ObjectiveBASS mixInNextTrack:] - previouslyInactiveStream is NULL #6
Description
I was listening to a track on iOS and I had played around with the queue and play/pause buttons a bit, trying to get things to break. Everything seemed fine until the track ended and the next track was about to start playing when I hit this assertion:
2018-07-27 15:47:48.985260-0700 Relisten[9079:2576352] [bass][preloadNextTrack] Preloading next track
Assertion failed: (BASS_Mixer_StreamAddChannel(mixerMaster, previouslyInactiveStream, BASS_STREAM_AUTOFREE | BASS_MIXER_NORAMPIN)), function -[ObjectiveBASS mixInNextTrack:], file /Users/pharkas/code/BASSGaplessAudioPlayer/BASS Audio Test/ObjectiveBASS.m, line 780.
It looks like thread 84 and thread 47 (the crashing thread) are both messing around with the inactive stream ivar at the same time.
The relevant code here is
if([self hasNextURL] && !isInactiveStreamUsed) {
dbug(@"[bass][stream] playback of %d finished and there is a next URL but there isn't a next stream. setting up", completedTrack);
[self setupInactiveStreamWithNext];
}
if(isInactiveStreamUsed) {
assert(BASS_Mixer_StreamAddChannel(mixerMaster,
previouslyInactiveStream,
BASS_STREAM_AUTOFREE | BASS_MIXER_NORAMPIN));
assert(BASS_ChannelSetPosition(mixerMaster, 0, BASS_POS_BYTE));
// now previousInactiveStream == self.activeStream
[self toggleActiveStream];
Here's some debugger info I grabbed:
