  • ffmpeg : deshake and crop 2k to 1080p ?

    12 septembre 2017, par est

    There are great tutorials of how to use ffmpeg to

    1. deshake a video, either via 1pass of deshake filter or using vid.stab for a 2pass filter
    2. how to downsampling to 2k video to 1080p

    I have a video taken by an action camera, it’s wide angle, so lots of margins could be cropped out, I want to

    1. deshake it and fix the camera to a center stage
    2. cropping a 2304 × 1296 video to 1080p, without downsampling.
    3. Convert original H.264 to HVEC to better file size

    How can I achieve this in one step without lossy intermediate video files ?

  • Quick stream from file which exists

    4 mai 2017, par parsa

    I implement live streaming from mp4 video file which exists on the path with ffmpeg under hls format.
    When my video file have the quality greater than hd720 , in encoding there are so many delays for creating .ts fragments.
    I mean the .ts fragments slowly produced on my path,and because of it I have so many delays in showing the stream.
    Here is my ffmpeg code for streaming :

    ffmpeg -re -i 123.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac 200p/out.m3u8 
    
              -s nhd -f hls -hls_list_size 0 -c:v libx264 -c:a aac 360p/out.m3u8 
    
              -s hd480 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 480p/out.m3u8 
    
              -s hd720 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 720p/out.m3u8
    
              -s hd1080 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 1080p/out.m3u8

    And here is the console output :

        ffmpeg -re -i ../files/412-887123464/video/412-887123464.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac ../fil
