However, I can't retrieve the playback time within the video filter module. The struct picture_t contains a member "date" that holds the display date but not the timestamp starting from zero when the playback started. There is apparently no way I can determine what is the current playback position especially after the user performs a seek operation using the seek bar.</p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 17.8048000335693px; background: rgb(255, 255, 255);">So, how do I determine the current playback position within the "video filter" module that stays consistent even after a seek operation?</p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 17.8048000335693px; background: rgb(255, 255, 255);"><span style="line-height: 17.8048000335693px;">Here is the sample code that will simply drop frames from 60 sec to 120 sec.
