  • Produce an adaptive multi-resolution mpeg-dash file from an input video file

    1er mars 2021, par Tariq Hasan

    I can produce different resolution mpeg-dash videos from running these commands separately and get one .mpd file for each of the resolutions :

    


    ffmpeg -i /path/to/input.mp4 -vf scale=1920:1080 /path/to/output.mpd
ffmpeg -i /path/to/input.mp4 -vf scale=1280:720 /path/to/output.mpd
ffmpeg -i /path/to/input.mp4 -vf scale=720:480 /path/to/output.mpd
ffmpeg -i /path/to/input.mp4 -vf scale=640:360 /path/to/output.mpd


    


    The question is, how do I get a single .mpd file that maps to all these different resolution videos which would be adaptive in resolution when streamed over the network ?

  • Merging four videos with differnt resolution in a Grid with ffmpeg

    5 juillet 2015, par Taufiq

    I want to marge four videos in to one as show below. I have achieve the correct output given all the videos have the same resolution. But I get an undesirable result with different resolution. See below for more details.

    ffmpeg code to get to merge 4 videos of different resution in a grid format

    ffmpeg.exe -i "1.avi" -vf "[in] scale=iw:ih, pad=2*iw:ih [left];movie=2.avi, scale=iw:ih [right]; [left][right] overlay=main_w/2:0 [out]" -b:v 768k "Output1.mp4"
    
ffmpeg.exe -i "3.avi" -vf "[in] scale=iw:ih, pad=2*iw:ih [left];movie=4.avi, scale=iw:ih [right]; [left][right] overlay=main_w/2:0 [out]" -b:v 768k "Output2.mp4"
    
ffmpeg.exe -i "Output1.mp4" -vf "pad=iw:2*ih [top]; movie=Output2.mp4 [bottom]; [top][bottom] overlay=0:main_h/2" "Output_Stacked.mp4"

    Code above gives the follow output.

    For Example

    But the problem arises when I rotate one of the videos and merge them.
