  • ffmpeg c/c++ get frame count or timestamp and fps

    25 octobre 2020, par broschb

    I am using ffmpeg to decode a video file in C. I am struggling to get either the count of the current frame I am decoding or the timestamp of the frame. I have read numerous posts that show how to calculate an estimated frame no based on the fps and frame timestamp, however I am not able to get either of those.

    



    What I need : fps of video file, timestamp of current frame or frame no(not calculated)

    



    What I have : I am able to get the time of the video using

    



    pFormatCtx->duration/AV_TIME_BASE


    



    I am counting the frames currently as I process them, and getting a current frame count, this is not going to work longterm though. I can get the total frame count for the file using

    



    pFormatCtx->streams[currentStream->videoStream]->nb_frames


    



    I have read this may not work for all streams, although it has worked for every stream I have tried.

    



    I have tried using the time_base.num and time_base.den values and packet.pts, but I can't make any sense of the values that I am getting from those, so I may just need to understand better what those values are.

    



    Does anyone know of resources that show examples on how to get this values ?

  • ffmpeg add watermark by output part count (watermark1.png for part 1, ...)

    12 octobre 2020, par Steapy

    I have currently following code (not optimized yet !) :

    &#xA;

    converter.StartInfo.Arguments = @"-i video.mp4 -i watermark.png -filter_complex ""overlay = x = (main_w - overlay_w) / 2:y = (main_h - overlay_h) / 2"" output%03d.mp4";&#xA;

    &#xA;

    This renders all my parts with the same "watermark.png" file as a watermark. But now i want to do something like this :

    &#xA;

    converter.StartInfo.Arguments = @"-i video.mp4 -i watermark%03d.png -filter_complex ""overlay = x = (main_w - overlay_w) / 2:y = (main_h - overlay_h) / 2"" output%03d.mp4";&#xA;

    &#xA;

    "output000.mp4" has "watermark000.png" as a watermark,&#xA;"output001.mp4" has "watermark001.png" as a watermark,&#xA;"output002.mp4" has "watermark002.png" as a watermark, ...

    &#xA;

    I need it in only one line, as if i would type it in cmd and it should work in c# with UseShellExecute=false.

    &#xA;

    Any idea ?

    &#xA;
