I am using the trim filter to cut out portions of my input pad that I do not want. I cannot use the -ss or -t option because I have to do trimming inside the filter-graph.
Here is my trim usage
trim=start=4:duration=4
The source is 10 seconds long, I just want to retrieve the portion starting at 4th second till 8th second. I get it with the above filter usage, but the output is still 10 seconds long with the trimmed out portions at the start and the end shown as "static" or paused frames. How do I get rid of those?
Edit: I was able to cut out the static frames at the start by using setpts=PTS-STARTPTS but what it did was, it added that extra duration at the end.
Here is my full command with output
