question about pipeline?

[Feynman1999]

Based on my poor knowledge, my understanding is that ffmpeg filters only support frame by frame synchronized image processing? And BasicVSR requires many frames before and after, can you explain how you support it? It would be even better if there was an overall technical introduction to help me understand this project.

it queues several frames for inference in the filter. Implementation details in https://github.com/OpenVisualCloud/Video-Super-Resolution-Library.Enhanced-BasicVSR/blob/master/ivsr_ffmpeg_plugin/patches/0002-Enable-multi-frame-fifo-with-BasicVSR-model.patch
