  • How to get frame number given a timestamp using ffmpeg

    1er décembre 2023, par Bartosz

    How can I get the frame number closest to a given time (relative to the start of the video) using ffmpeg ? The video has variable frame rate. I do not need any other metadata or the actual frame (image) itself. Speed is more important than precision (unless the possible error is more than a couple of seconds).

    


    Example :

    


    Input

    


      

    • video.mp4 (assuming ideal constant 30 fps for simplicity)
    • 


    • 00:00:05 (HH:MM:SS)
    • 


    


    Output

    


      

    • 150

  • How can we extract the RTP packet sequence number from AVPacket (ffmpeg)

    6 septembre 2019, par Nech

    We are trying to extract the "Sequence Number" from the RTP header of a packet.
    We use av_read_frame in order to read the packets into AVPacket structs.

    We tried using the AVPacket.data field, hoping it holds the original payload, but we didn’t manage to find the right location of the header. So we assume that the data field does not hold the full payload - please correct if we are wrong.

    Is there a way to find the RTP header information ?
