Rendering 8x slower with version 193

[stefandrissen]

I updated to the latest version (193 | 2023-09-17) today and noticed that the rendering time has increased dramatically. I was using an older 2022-09-28 (not sure where these dates are coming from) version.

After 10%, the ETA on the same source files:

193: 1 hour 20 minutes
192: 10 minutes
191: 10 minutes

I am using a 4 core HT PC - with version 193 all 8 logical cores are near 100%.

I am using wav files as input.

The speed was the same but there was a logic error that caused it to render way more frames than there was data. This was a mistake introduced when I added support for MP3s as sources. It should be better in v194.
