Thanks. frame copy concealment should work by default after frame drop, right? Because during my experiments when I am dropping B slices which sometimes means whole B frame, it is not enabling frame copy as I am getting only 299/300 frames. Is there any way to enable it or should I report it as a bug? Let me know.

completely lost frames are handled ultimately by ffmpeg.c duplicating
the previous frames. when the output format cannot handle frames of
We also have some interpolation concealment for B frames in
