  • FFMpeg : how to use between() to select last second ?

    13 mai 2019, par rcpinheiro

    I’m trying to apply a caption using drawtext that should disappear one second before the video end :

    ffmpeg -i input.mp4 -vf "drawtext=enable='between(t,0,5)':fontfile=font.ttf:text='Some caption':x=60:y=640:fontsize=40:fontcolor=#f0f0f0@0.9" -vcodec libx264 -crf 27 -preset ultrafast -strict -2 -acodec copy output.mp4

    The problem is that I don’t know the video length beforehand. I’ve tried using ’between(t,0,-1)’ but it doesn’t work, the caption never shows up.
    Anyone knows if is there a way to do this without having to open the video first to check length and only after that draw the caption ?
    Thanks in advance !

  • Ffmpeg desyncing with FFSource

    28 janvier 2014, par Ismaw34

    i don't know how much time i spent doing the batch to stream with twitch, i made a batch file for streaming, but the audio and the video are desyncing over time.

    The batch im using is this :
    http://pastebin.com/NEz2Gvyj

    I dont know if my pc is too old for streaming or if is something else.

    With XSplit the quality is pixelated a lot.
    Can't use OBS.
    With FFSplit is the same as above.

    Thanks in advance.

    It appears that the new batch is working now. Thanks for all the visits, you can use the batch too.
