Video frame lost and scene filter output

[haiying7]

Hi,

I use VLC to play an 85 seconds video. The frame rate is 12 frames/sec. Normally, with scene filter, it should output 1020 frames as the recording ratio is 1. If the video has some packet lost, I find the output only has 876 frames, but the duration is still 85 seconds. How does it happen? Does VLC use any blank frames to compensate the lost frames?

Thanks.
