• Timestamp not printed on thumbnails with FFMPEG

  26 août 2021, par mlatelcom

  I have a script using FFMPEG to generate an image with tiled thumbnails every 45 seconds for several videos on a given folder. The images are named with the name of the video it was generated from. It generates the thumbnails for each video but it does not print the time stamps on them. The path to the font file is correct ; so I don't know where the issue is. I'm using the script in Fedora Linux.

  


  Here is the FFMPEG command line code on the script :

  


   ffmpeg -ss 00:00:05 -i test.mp4 -loglevel 40 -frames 1 -bt 20M -vf "drawtext=fontfile=/usr/share/fonts/open-sans/OpenSans-Light.ttf:timecode='00\\:00\\:00\\:00':r=30:fontcolor=white:x=220:y=220:box=1:boxcolor=black@0.5,select=not(mod(n\,1350)),scale=200:150,tile=15x48" -n "${name}.png"


  


  and this is the console output

  I am trying to achieve an animation effect using ffmpeg. I am adding text watermark to an input video and animate the text diagonally, horizontally or vertically changed randomly. Here is what I have achieved so far.

  


  ffmpeg -i video.mp4 -c:v libx264 -preset veryfast -crf 25 -tune zerolatency -vendor ap10 -pix_fmt yuv420p -filter:v "drawtext=fontfile=./fonts/Roboto/Roboto-Light.ttf:text='Watermark':fontcolor=white:alpha=0.5:fontsize=60:y=h/10*mod(t\,10):x=w/10*mod(t\,10):enable=1" -c:a copy watermark.mp4

  


  Here is what I want it to work.

  


  Initial Position :
The watermark randomly placed in the video the first time they appear.

  


  Continuous Movement :
The watermark continuously moves within the video.
The direction and speed of the watermark's movement are random. It can move diagonally, purely horizontally, or purely vertically.
When the watermark reaches the boundaries of the video, it bounces back, changing its direction.

  


  Direction Change :
During its continuous movement, the watermark will suddenly change its direction at random intervals between 3 to 6 seconds.
When changing direction, the watermark can randomly determined move diagonally, purely horizontally, or purely vertically.

  


  Fade In and Out :
Every 10 to 20 seconds (randomly determined), the current watermark begins to fade out.
As the old watermark starts to fade out, a new watermark fades in at a random position, ensuring that there's always a visible watermark on the screen.
These two watermarks (the fading old one and the emerging new one) overlap on the screen for a duration of 2 seconds, after which the old watermark completely disappears.
These patterns and characteristics together provide a dynamic, constantly moving, and changing watermark for the video

  


  To achieve the result I think we can use the drawtext multiple times. I have attached the HTML and JavaScript variant just for the reference to understand the result but I am trying to do this using ffmpeg.

  


• Android-FFmpeg adding subtitle to mp4 video does not work

  7 septembre 2022, par ebdaa app

  I am trying to add srt file to a mp4 video using android mobile-ffmpeg , the code works with no error but the generated video does not contain the subtitle

  


  here is the code :

  


   String cmd = "-i " + videoPath + " -vf subtitles=\"" + subtitlePath + ":force_style='Alignment=10,Fontsize=18'\" " + OutputVideoPath;
 FFmpeg.executeAsync(cmd, new ExecuteCallback() {
    @Override
    public void apply(final long executionId, final int returnCode) {
         if (returnCode == RETURN_CODE_SUCCESS) {
         } else {
             
         }
    }
 });


  


  here are the logs

  any idea why the generated video does not contain the subtitle ?

  


  Update

  


  Based on below comment , I changed my code to use the latest ffmpeg-kit version , here is the new code

  


  String cmd = "-i " + videoPath + " -vf subtitles=\"" + subtitlePAth + ":force_style='Alignment=10,Fontsize=18\" " + 
   outputVideoPath;

   FFmpegKit.executeAsync(cmd, new FFmpegSessionCompleteCallback() {

        @Override
        public void apply(FFmpegSession session) {

        }
    }, new LogCallback() {

        @Override
        public void apply(com.arthenica.ffmpegkit.Log log) {


        }
    }, new StatisticsCallback() {

        @Override
        public void apply(Statistics statistics) {              

        }
    });`


  


  and here is the updated log
