  • FFMPEG, DrawText Issue in Live Stream

    7 décembre 2022, par Kenneth

    I am using the following command to create an H264 stream with text data from a text file. Example data is fake. I am sending this to an RTSP server that then allows clients to connect. I am connecting from VLC to view the stream.

    


    See update, this only happens for the live stream. If I output to file, it looks correct.

    


    OS : Windows 10

    


    ffmpeg -f lavfi -re -i color=size=1280x720:rate=1:color=black ^
  -vf drawtext="fontsize=16:fontfile=C\\:/Windows/fonts/consola.ttf:fontcolor=white:textfile='livetext.txt':x=50:y=50: reload=1" ^
  -c:v libx264 -preset ultrafast -tune zerolatency -x264-params keyint=10:min-keyint=10 ^
  -f rtsp rtsp://127.0.0.1:60000/sorting


    


    The issue I am having is that the text shown in the video seems to be limited to 10 rows. On a fresh restart, I get even less. I don't see anything mentioned in the documentation about a limitation on length.

    


    I have tried different -preset and -tune options. Nothing improves this issue.

    


    Are there settings I should adjust to help this ?

    Update 1 :

    


    If I output to a file, the text is shown correctly (shown below). If I take out the -re argument for the output to match input rate, I get 150fps, so processing power does not seem to be the issue.

  • ffmpeg converting JPG slideshow to H264

    22 décembre 2018, par phol

    I am trying to convert a set of jpg files to a slideshow with varying durations using ffconcat

    output.txt contents :

    ffconcat version 1.0
    
file slide_0001.jpg
    
duration 0.163
    
file slide_0002.jpg
    
duration 0.533
    
file slide_0003.jpg
    
duration 1.067
    
file slide_0004.jpg
    
duration 0.533
    
file slide_0005.jpg
    
etc.

    FFmpeg command :

    ffmpeg -i output.txt output.mkv

    I also tried :

    ffmpeg -i output.txt -c:v copy output.mkv

    However, when converting, the colours of the images become skewed.
    White becomes pink / purple and dark green becomes light green.
    The same happens when choosing different codecs and containers.
    Is there a way to solve this ?

    EDIT :
    I performed the same conversion again. I attached the log output as requested.
    However, in the meantime I have figured out that converting without ffconcat duration and then altering timecodes with mp4fpsmod is more efficient in terms of storage (3 vs 40 MB) and gives less issues in different players. The result is nonetheless the same : colours are still wrong, both on my workstation (Ubuntu 18.04) and laptop (macOS Mojave).

    I tried to alter things with pix_fmt and -vf format as can be seen in the second log output. This did not solve the problem.

    Background info :
    The input jpg files are from a lecture recording made with MediaSite, which has both a video stream for the room as well as this slideshow stream for the slides.

    Example of input :

  • 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 ?
