Stream copy given start and end time in ffmpeg
10 mai 2013, par praks411I'm trying a small program which cuts clip from video file given start and end time. For this I'm doing a simple stream copy of both audio and video stream. I just copied the pts and dts from input packet to output with proper re-scaling. However the output which I'm getting is blank for some duration and then only for last few seconds it is displayed. I thought this could to problem of incorrent pts and dts. So I just manually set pts and dts using counter for each stream. Though I'm able to get the clip but video is very fast and audio goes fine. Please someone explain me how to set current pts and dts for both audio and video stream, when doing stream copy.
Thanks

Finding the time of a thumbnail in a video
10 mai 2013, par LiamI have a large set of pre-generated thumbnails and videos. What is the easiest way to figure out the specific time in the video of the associated thumbnail ?
I'd imagine that I would have to use something to loop through all the frames in a video to find a match. What libraries should I use ? Something like OpenCV maybe ? ffmpeg ?
Python is preferred but not required.
