I performed a careful review, below, using the latest build. Note that decimate=ppsrc=1 removes the 2nd of the repeat-pair except for the first instance (frames 938 & 939). In the first instance, the the 1st of the repeat-pair is removed. That bothers me a bit. I anticipated that the first frame of 'target dupthresh=1.0.mkv' & 'target dupthresh=1.5.mkv' would be frame 938. That it's 939 makes me wonder about ppsrc's initialization.
'source.mkv' frame numbers | 'target dupthresh=1.0.mkv' frame numbers | | 'target dupthresh=1.5.mkv' frame numbers | | | 938 939 repeat 939 939 940 940 940 941 combed 941 941 942 combed 942 942 943 943 943 944 repeat 945 945 945 946 combed 946 946 947 combed 947 947 948 948 948 949 repeat 950 950 950 951 combed 951 951 952 combed 952 952 ...etc. How do I know it was frame 938 that was removed? Because the frame numbers are burned into 'source.mkv'. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
