Just a quick note- playback of opus audio files (assume is VBR) may be a little uneven in pitch/playback speed for a few seconds right after seeking within the track. This refers to opus audio which I did not encode and which has also been trimmed using ffmpeg (codec set to "copy" so no transcoding).
It's fine for normal playback, but seeks cause several seconds of slight pitch instability. Just something to be aware of so you don't wonder if the file is bad.
Adjusting decoding priority had no effect on this.
