How do you print just the stats line when using FFplay?

In FFmpeg printing just the stats line in the console is as simple as including -loglevel quiet -stats, but the same does not work in FFplay. Running these arguments I just get nothing in the console: $argumentList = @(“-loglevel”, “quiet”, “-stats”, “-i”, “-x”, “848”, “-y”, “480”, “`”$filePath`””) Is it possible to make FFplay less verbose […]

I have a Box class that updates every frame: class Box: def __init__(self, x, y, width, height): self.rectbox = pyg.Rect(x, y, width, height) def update(self): […]

Pandas: Groupby names in index and columns

I have a dataframe that uses MultiIndex for both index and columns. For example: df = pd.DataFrame(index=pd.MultiIndex.from_product([[1,2], [1,2,3], [4,5]], names=[‘i’,’j’, ‘k’]), columns=pd.MultiIndex.from_product([[1,2], [1,2]], names=[‘x’, ‘y’])) for c in df.columns: df[c] = np.random.randint(100, size=(12,1)) x 1 2 y 1 2 1 2 i j k 1 1 4 10 13 0 76 5 92 37 52 […]
