  • What's the best way to get video metadata from a video file in ASP.Net MVC using C# ?

    15 mars 2021, par Maddhacker24

    I've been searching on Google and StackOverflow for a good couple of hours. There seems to be a lot of similar questions on StackOverflow but they are all about 3-5 years old.

    



    Is using FFMPEG still the best way these days to pull metadata from a video file in a .NET web application ? And if so, what's the best C# wrapper out there ?

    



    I've tried MediaToolkit, MediaFile.dll without any luck. I saw ffmpeg-csharpe but that looks like it hasn't been touched in a few years.

    



    I haven't found any current data on this subject. Is the ability to pull metadata from a video built into the latest version of .NET now ?

    



    I'm basically looking for any direction at this point.

    



    I should add that whatever I use could be invoked thousands of times per hour so it will need to be efficient.

    


  • Get a still frame during video capture on Linux

    15 janvier 2020, par Arthur Hebert

    I want to capture video from a webcam (saving to file), and occasionally get the most recent still frame on-demand (from python code), while continuing to capture. Is there a way to do this on Linux ?

    To capture video, I am using the following command :

    ffmpeg -f v4l2 -framerate 30 -video_size 1024x576 -i /dev/video0 myvideo.mp4

    Then in another terminal, I try to capture the latest still frame :

    ffmpeg -sseof -3 -i myvideo.mp4 -update 1 -q:v 1 current_frame.jpg

    I get varied responses from this last command, including

    Cannot use -sseof, duration of myvideo.mp4 not known

    and

    [matroska,webm @ 0x55e1aae26900] Duplicate element
       Last message repeated 2 times

    Constraints :

    1. I need to control the solution from python (e.g. calling ffmpeg via subprocess.Popen) to (a) start recording, (b) get frames at arbitrary points, (c) stop recording.

    Flexibility

    1. The frame timing doesn’t have to be exact. It’s okay for it to be a frame within the last couple seconds.
    2. I am not attached to a particular container format (mkv, mp4, etc.)
    3. I am open to programs other than ffmpeg (it’s nice if it works on Windows too, but not required)

  • ffmpeg set output resolution by resizing image

    3 janvier 2020, par Martin

    I’m trying to use ffmpeg for rendering video where an audio file and image are taken as inputs, and turned into a video (basically a music video) with the audio file playing for the duration of the video.

    My current working command :

    ffmpeg -loop 1 -framerate 2 -i "front.png" -i "testWAVfile.wav" -vf "scale=2*trunc(iw/2):2*trunc(ih/2),setsar=1,format=yuv420p" -c:v libx264 -preset medium -tune stillimage -crf 18 -c:a aac -shortest -vf scale=1920:1080  "outputVideo.mp4"

    Will set the output resolution of the video to whatever the resolution of the image is. Is there a way I can resize the image to enlarge it by a couple multiplications so that the output video resolution will be higher ?

    Like if my front.png image was 800x800 pixels, I could add something to my ffmpeg command to triple the resolution, so that the output video resolution is 2400x2400 ?
