  • Pas question de marché, de cloud etc...

  • FFMPEG Incredibly Slow On Windows Server 2016

    1er août 2019, par Ben Gardner

    I have a t2.small (2GB RAM, 1 vCPU) Amazon EC2 instance running a process using FFMPEG. It runs just fine ( 30 fps) on my computer (i7, 12GB RAM), but at around 2 fps on the server. Here’s the command :

    rescale_command = f'ffmpeg -i {srcVideo} -filter_complex \"scale={owidth}:{oheight}, setsar=1:1, pad={dim[0]}:{dim[1]}:{oofx}:{oofy}\" {destVideo}'

    I’ve tried uninstalling and reinstalling ffmpeg/ffprobe

    Edited per llogan’s request, I’ve also discovered that it’s relatively speedy towards the beginning (I’m rescaling 100 times over the course of the program) and slows down towards the end.

    It utilizes 100% of the CPU even from the beginning, though.

    Example command/output :
    ffmpeg -i media/8-1-2019/hi/dl-107.mp4 -filter_complex "scale=607:1080, setsar=1:1, pad=1920:1080:656:0" media/8-1-2019/hi/sl-107.mp4

  • ffmpeg mp4 fade output appears faulty [duplicate]

    19 septembre 2015, par DaveTheRave

    This question already has an answer here :

    I can add a fade in and out to an existing MP4 with the following command and it works perfectly (from and to black) - it plays in all browsers and a range of Android devices

    ffmpeg -i phpF21_i_v.mp4 -vf "fade=in:1:30, fade=out:st=4:d=1.0" -y phpF21_i_final.mp4 >phpF21_i_f.log 2>&1

    But if I try to fade from and to white, the following command doesn’t work - it only plays in Chrome - no other browser - not on Android

    ffmpeg -i phpF21_i_v.mp4 -vf "fade=in:1:30:color=white, fade=out:st=4:d=1.0:color=white" -y phpF21_i_final.mp4 >phpF21_i_f.log 2>&1

    Am I missing something obvious ?

    Cheers

    Dave

  • Restreaming hls stream to rtmp stream using ffmpeg

    7 décembre 2018, par dhruv shah

    I am trying to re-stream an hls stream to rtmp stream using ffmpeg :

    as example :

    ffmpeg -loglevel debug -re -i "https://hddn01.skylinewebcams.com/live.m3u8?a=c6kekc4h116t1m5jbtei273bq0" -bufsize 4000k -preset ultrafast -vcodec libx264 -tune zerolatency -b:v 900k -an -f flv rtmp://127.0.0.1/live/stream.flv

    The stream is available on the website :
    https://www.skylinewebcams.com/en/webcam/malta/malta/traffic/traffic-cam2.html

    The issue is that input fps value is very low and q value is very high or -1 most of the times.

    Please take a look at the following log :
