  • Show a tcp video stream (from FFPLAY / FFMPEG) in an C# application

    24 avril 2021, par Rob

    I' trying to make my Parrot AR Drone 2.0 work with a Windows machine.

    


    I have a simple C# application to control it - but now i want the video stream inside of my application.

    


    If I execute ffplay tcp://192.168.1.1:5555 it connects to the videostream and shows a window with the video.

    


    How can I get this video inside of my application ? Like, a simple 'frame' or 'image' that gets filled with that content ?

    


    I have never worked that much with C# so any help would be awesome.

    


  • ffmpeg adjust contrast, show histogram

    10 juin 2018, par UltrasoundJelly

    I’m trying to first adjust the contrast of a frame extracted from an mp4, then overlay the histogram of the resultant frame on top. My command here does all of this, but also adjusts the contrast of the histogram itself. Is there a single ffmpeg command that can do what I wish ?

    enter image description here

        ffmpeg -ss 3.5 -i in.mp4 -an -y -vf \
    
    "split=2[a][b],[b]eq=0.5:0:1:1:1:1:1,histogram=levels_mode=logarithmic:\
    
    components=1:level_height=100, [a]overlay,eq=0.5:0:1:1:1:1:1" \

  • How to compare/show the difference between 2 videos in ffmpeg ?

    25 janvier 2016, par polarka

    I am a newbie at encoding. I have read and tried x264 in lossless mode (-qp 0), however I’d like to make sure that in my new video, every single pixel contains the same information as the source file (which is in YUV 420 so the loss of color conversion is avoidable, as far as I know). I want to be able to check that, because I don’t believe in that if someone just says its lossless.

    I welcome answers suggesting other codecs for lossless encoding, my only requirements for codecs are having one of the best compression rate and let me to pick different calculation times (such as the range from placebo to veryfast in x264) in order to adjust the compression level and calc time to my needs. But keep in mind that the original question is about how can I calculate the differences frame by frame of two videos and export it to a 3rd file, so I can watch it myself. I think that knowledge (if its possible and doesnt have serious limitations) will be useful for me in the future too.
