  • Remapping multiple Mp4 videos into a single one with ffmpeg

    21 septembre 2016, par Josep Bosch

    I’m interested in remapping multiple (6) MP4 videos into a high resolution final video according to lookup tables I calculated. The idea is convert 6 independent videos in a 360º video according to an equirectangular projection.

    Equirectangular image example
    Example of equirectangular video here

    Is there a way to do this remapping with ffmpeg or any other linux program ?
    Right now I’m extracting all the frames from the videos, creating the equirectangular individual images and joining them again into a video. There must be a better way for this...

    UPDATE :

    Following Mulyva’s suggestion I first remap each individual video using the remap filter. Those parts of the panoramic video not covered are interpreted like chromakey pixels using :

    ffmpeg -i videos/camera1.MP4 -i camera0_map_x_radius5.pgm -i camera0_map_y_radius5.pgm -lavfi remap -qscale 1 out0.MP4

    Camera0

    Camera1

    Then I try to overlay them using the chomakey filter :

     ffmpeg -i out0.MP4 -i out1.MP4 -filter_complex "[1:v]chromakey=0x12da11:0.2:0.2[chromakey_res];[0:v][chromakey_res]overlay=eof_action=pass[out]" -map "[out]" out.mp4

    As you can see, the final result has an undesirable green shadow. Any idea of how to remove it ?

  • Ffmpeg one image video convert faster

    27 août 2015, par user997841

    At the moment I can convert a video with one image and an mp3. I was wondering how I can make the converting faster, because it takes 5min to render one image and place an mp3 of 3min.

    ffmpeg -y -loop 1 -i image.jpg -i track.mp3 -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest final.mp4

    Thx !

  • Tokbox archived video is letterbox (black border around video)

    28 août 2017, par Bijan Markes

    I have archiving setup to save my tokbox publisher streams straight to an AWS S3 Bucket ; But the final saved archive.mp4 is appearing letter-boxed / has black borders around the stream video rather than stretching the video to fit the whole frame. Is there any way to change this ? It is completely on the tokbox end and I also have the fit-mode for the publisher set to "contain" although changing it to cover doesn’t change anything. Thanks.
