Android FFmpeg Video Recording Delete Last Recorded Part
17 avril 2015, par user3587194I’m trying to do exactly what this picture shows.
Anyway, how can I delete part of a video ? The code I was testing is on github.
It uses a progress bar so that when you record the progress bar will move, and keep them in separate segments. What is confusing to me is trying to figure out where and how to grab each segment to see if I want to delete that segment or not.
