FFMpegFilter #149

Open x850044053wwt opened 1 day ago

x850044053wwt commented 1 day ago

I added 3 ffmpeg filters, but there is only one filter node in the final dump result. Is it because optimize has optimized it out? Why is there only one filter left?

I encountered a problem where the speeds of 3 filters were inconsistent. The slow filter filled up the filter node queue, causing the fast filter to be blocked.

Yes, filters will be merged into one filtergraph by default, but if you want them run by different nodes, it can be configured like this: graph.set_option({'optimize_graph': False})
