  • How to get time stamp of closet k-frame before a given timestamp with ffmpeg ?

    20 février 2013, par jAckOdE

    I want a ffmpeg seeking command that fast and accurate. I found this

    The solution is that we apply -ss for both input (fast seeking) and output (accurate seeking). The question is that if the input seeking is not accurate how can we be sure that the seeking position is accurate.

    For example : as the example used in the link, if we want to seek to 00:03:00, the command is something likes

    ffmpeg -ss 00:02:30 -i ... -ss 00:00:30
    As said, the first seeking will seek to somewhere else not 00:02:30, say 00:02:31. and after applying second seek, the final result would be 00:03:01- NOT what we want. Is that correct ?

    Where does fist seeking seek to ? Does it seek to k-frame that closet to 00:02:30 ?

    If so, here is my thought, correct me if i'm wrong : after first seeking, we get the timestamp of the result (in this example : 00:02:31), then we apply second seeking with appropriate time, in this case 00:00:29.

    Question is how do we get time stamp of first seeking's result ?

  • Stream copy given start and end time in ffmpeg

    10 mai 2013, par praks411

    I'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
