  • How to convert raw video formats to mp4/mov with CLI based tool something like ffmpeg ?

    29 octobre 2022, par A_Mishra

    Want to convert raw video formats like braw, redcode and canon raw format into mp4/mov videos with command line tool such as ffmpeg. There are dedicated softwares for conversion like DaVinci Resolve for braw format, but I am looking for something to use as service and use it within my code thus looking for CLI based solution.

    


  • Extracting frame out of video based on time in seconds

    20 avril 2024, par Vicky

    I'm developing a web-based video editing tool where users can pause a video and draw circles or lines on it using canvas. When a user pauses the video, I retrieve the current playback time in seconds using the HTML5 video.currentTime property. I then send this time value along with the shape details to the server. On the server-side, we use FFmpeg to extract the specific paused frame from the video. The issue I'm encountering is a frame mismatch between the one displayed in the browser and the one generated in the backend using FFmpeg.

    


    I've experimented with various approaches for this process.

    


    Extracting frame based on time. Example : in this case time is 3.360 second.

    


    


    ffmpeg -i input.mp4 -ss 00:00:03.360 -frames:v 1 frame.jpg

    


    


    Converting time to frame number using the following logic : Math.round(video.currentTime * fps)

    


    


    ffmpeg -i input.mp4 -vf "select=eq(n,101)" -vsync vfr frame.jpg

    


    


    


    ffmpeg -i input .mp4 -vf "select='lt(t,3.360)lt(3.360-t,1/31.019)',setpts=N/(31.019TB)" -vsync 0 frame.jpg

    


    


    The challenge I'm facing is that sometimes the frame I see in the browser at the pause time doesn't match the one generated in the backend using FFmpeg. How can I solve this problem ? If it's an issue with currentTime, are there any other approaches I can try ?
