Real time ffmpeg / x264 encoder behavior when input resolution suddenly changes I want to take a live HD-SDI signal being captured by a capture card and encode it in real time to X.264.

What happens when the input resolution suddenly changes? eg, from HD SDI 1080/50i to HD SDI 720/59p, etc.

Does the encoder handle that gracefully? Or would there be some artifacts/disturbance in the output? (or worse?)
FFmpeg will automatically insert scale filter to rescale to first resolution when it encounters input resolution changes. Obviously this only applies when encoding.
