  • MP4 Videos are playing only after fully loaded on Jwplayer

    25 octobre 2014, par Hamza Iqbal

    Hi recently I am converted some videos to MP4 using FFMpeg but When I am trying to stream this video files, player needs to load a file completely, until it starts to play, I am trying to find a way to make it start play a file right from the start and keep on loading as well.
    I am using this FFMpeg command for conversion :

    ffmpeg -i input.mp4 -vcodec libx264 -vpre default -crf 28 -ac 1 -ar 44100 -b 284k -ab 70k -r 15 -s 640x360 output.mp4 2>&1

  • Generate Black frames between concatenated videos ffmpeg

    9 février 2019, par Alex K

    I’m trying to concatenate 2 videos together using ffmpeg concat, but I want to have there be 2 seconds of black between the 2 videos.

    The problem is that whenever I’ve tried to generate a black video and concatenated it in, the properties never match my input video exactly, and so the concatenation is all broken - the audio is broken or the frames change at the wrong speed or generally concatenation fails.

    Here’s the output of ffmpeg -i my_input_video1.mp4 (and is identical for my_input_video2.mp4) :

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'input_vid1.mp4':

    Metadata:
    
      handler_name    : SoundHandler

    How can I generate a 2 second black video with these properties so that it can be concatenated with my input videos ?
