    tried with and without sudo, tried changing rtsp ://... to http://
also tried udp but get same output..

    


    chacked that the port is not in use(8888) and different ports (1935...) but still the same.

    


    i installed ffmpeg via brew install...

    


    when i run some test server on my localhost i never have issues ussing an unused port

    


    really stuck here and any help would be amazing...thank you

    


    EDIT :
Problem was in the command i used : "rtsp ://127.0.0.1:8888/live" - but i did not have a running server capable of accepting the data from ffmpeg and redestributing it - so i had to first run such server and only after that to run ffmpeg :

    


    Servers which can receive from FFmpeg (to restream to multiple clients) include ffserver (linux only, though with cygwin it might work on windows), or ​Wowza Media Server, or ​Flash Media Server, Red5, or ​various others. Even ​VLC can pick up the stream from ffmpeg, then redistribute it, acting as a server.

    


    i used the VLC option. You can read about it here : http://trac.ffmpeg.org/wiki/StreamingGuide

    


  • Reverse and areverse crash the computer

    14 août 2019, par Alex

    I am using this command :

    ffmpeg -y -ss 00:03:52.612 -i "H:\DCIM\100GOPRO\GOPR3258.MP4" -r 60 -t 00:00:12.140 -vf reverse -af afade=t=in:ss=0:d=1,afade=t=out:st='00\:00\:11.140':d=1,areverse 6.mp4

    It increases the memory consumption of the computer to a point of collapse.

    Putting it like

    ffmpeg -y -ss 00:03:52.612 -i "H:\DCIM\100GOPRO\GOPR3258.MP4" -r 60 -t 00:00:12.140 -af afade=t=in:ss=0:d=1,afade=t=out:st='00\:00\:11.140':d=1 6.mp4

    Works without a problem.

    Therefore, the issue is in the -vf reverse and -af reverse.

    The output is

[aac @ 0000024b71498b40] Qavg: nan

    What I find interesting is

    Only '-vf reverse' read, ignoring remaining -vf options: Use ',' to separate filters

    As there is only -vf reverse

    Only '-af afade=t=in:ss=0:d=1,afade=t=out:st='00\:00\:11.140':d=1,areverse' read, ignoring remaining -af options: Use ',' to separate filters

    Here the same.

    I tried

    ffmpeg -y -ss 00:03:52.612 -i "H:\DCIM\100GOPRO\GOPR3258.MP4" -r 60 -t 00:00:12.140 -vf "reverse" -af "afade=t=in:ss=0:d=1,afade=t=out:st='00\:00\:11.140':d=1,areverse" 6.mp4

    to no avail

    What is causing this issue ?

  • SOLVED - FFMPEG 'Fontconfig error : Cannot load default config file' error Windows

    27 février 2019, par Merel

    I am trying to make a short video in FFMPEG, where a word stays on screen for the duration of the video (0.5s). My FFMPEG code looks like this :

    ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf "drawtext=fontfile= ‘c\:\Windows\fonts\calibri.ttf':fontsize=18:  fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4

    However, I keep getting the following error (see below for full output) :

    Fontconfig error: Cannot load default config file 
    
[Parsed_drawtext_0 @ 000001c2918cef00] Using "C:/Windows/fonts/mingliub.ttc"

    I figured it had something to do with the path to the font file. I also tried copying the font file to my FFMPEG map and map the font path to the FFMPEG directory :

    ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf
    
"drawtext=fontfile=‘C:\FFMPEG\bin\calibri.ttf':fontsize=18: 
    
fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4'

    This doesn’t work either. I do get an output video.mp4 video, but the font is wrong. Here is the full output I get. It is the same for both code examples above :

     c:\FFMPEG\bin>ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf "drawtext=fontfile= ‘c\\:\\\Windows\\\fonts\\\calibri.ttf':fontsize=18:  fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4

    SOLVED ! Apparently the problem was that the path to the font cannot contain a semicolon (i.e., "C :/". The code that worked is :

    ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf “drawtext=fontfile= /Windows/fonts/calibri.ttf:fontsize=18: fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text=word” output.mp4
