// NOTE(fox): Even though each layer has its own completely isolated AV
// instance, it appears two layers with the same file still share something.
// When the layers aren't at the same position in time, the playhead of one
// layer gets misaligned every few frames and causes a manual seek back to the
// position. Different files don't exhibit this behavior.
