I've noticed two anomalies with LAV CUVID which, while they don't seem to be a problem for me, may be of interest. I haven't tested really extensively, but in my setup (which includes Zoomplayer and madVR), they happen reliably with LAV CUVID and not with other decoders.

1) GPU memory usage (as displayed by GPU-Z). Whenever I stop playback and then start it again, the memory usage is higher than it was before. This continues until the upper limit of memory is reached, then it stays at that value. Playback is fine, even after the upper memory limit is reached. The memory only goes back to zero when I exit Zoomplayer.

2) madVR Windowed Mode with interlaced material. This causes constant dropped and delayed frames. It's fine in Full Screen Exclusive mode and also fine with non-interlaced material in both modes.
