ZDoom

Description:
When playing with custom oggs, occasionally they'll "skip" like an old CD-player. It's consistently around the same length every time, but this length varies from session to session. Before importing these oggs and after exporting them with slade, they sound fine, but in-game the skipping occurs. This doesn't happen to every ogg. As far as I can tell, this is only happening with OGGs larger than 4 MB.

Priority: Eh? Not high, but there could be something more insidious causing it?

Steps to Reproduce:
1. Open GZDoom with a resource that has custom OGGs larger than 4 MB.
2. Play as normal, but stay in a level long enough to let the music finish at least once.

Does it only happen after looping? Is music affected, or sound effects, or both? "Oggs larger than 4 MB" is a bit vague, and I tested with an 8.4MB Ogg without any noticeable problem after looping. Do you have a specific file exhibiting the problem?

I've not noticed any lagging with large OGGs on my end and we use loop points extensively.

I also never experienced this kind of thing with recent code. A long time ago there was a problem like this when looping MP3's but that was due to a bug in the decoder library that could be worked around. What GZDoom version are you using?

To answer your questions:

It happens the first time it plays, and it only happens with music. Two specific tracks seem to do this, but none of the rest of the tracks in the wad exhibit this behavior. In addition, while played in SLADE and while played outside of the game, these oggs play back normally.

I'm using GZdoom 4.5.0.

So, what tracks? Can you post a link?
And what's your system's specs, e.g. CPU type, how many cores, SSD or HDD?

I have a question. Does your audio files have looping points?
