Comment (by uklotzde):
This bug can also be verified with one of our test files:
https://github.com/mixxxdj/mixxx/blob/master/src/test/id3-test-data/cover-
test.ogg
1st frame: pts = 0, nb_samples = 576
2nd frame: pts = 1024, nb_samples = 576
3rd frame: pts = 1152, nb_samples = 128
...
The new FFmpeg decoder (work-in-progress) correctly detects those
inconsistencies caused by overlapping frames.
Our tests for sample accurate decoding fail when decoding OGG files using
FFmpeg.
