• FFMPEG sendcmd command limitation

  18 novembre 2022, par Stahlauge

  i try to draw text into a video with drawtext and sendcmd.
In the sendcmd file there are over 9100 commands defined (each frame needs a different text).
All my commands are build this way.

  


  0 Parsed_drawtext_1 reinit 'text=\102030GA01, 102040Ap05
von oben, in Fließrichtung
[0,00]   17.11.2022 10\:22\:04:fontsize=28.928569157918293:y=5:x=0:fontcolor=#FFFFFF';
0.04 Parsed_drawtext_1 reinit 'text=\102030GA01, 102040Ap05

  My command is.

  


  ffmpeg.exe -y -i "17112022_102204.mp4" -vf "sendcmd=f=drawtextcommands.cmd,drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=black@1.0:line_spacing=5, drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=yellow@1.0:line_spacing=5,drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=yellow@1.0:line_spacing=5,drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=green@1.0:line_spacing=5" -c:v mpeg4 -qscale:v 5 -f mp4 "102030GA01_2022-11-17_10-21.mp4"


  


  My ffmpeg Version is n5.0.4 lgpl.
If i run this command with the sendcmd file on my develop laptop it works just fine (i7-10850H and 32GB RAM) but if i run the excat same on a Surface (i5-1035G4 and 8GB RAM) or Dell Latitude 5175 (Intel m5-6Y57 and 8GB RAM) i get an error

  


  [Parsed_sendcmd_0 @ 000002454188c540] No Targed specified in interval #XXXX, command #0 


  


  where XXXX is different each time i run it. All PC runs Win 10.

  


  I can´t really find the problem why i get this error on the tablets but not on my Laptop.
Maybe it´s a hardware ressource problem even FFMEG doesn´t have any requirements at all ?

  


  I only can get it to run on the tablets if i delete lots of commands from the sendcmd file.
I can´t define excatly the amount i need to delete because each run i can have more or less commands that are working.
But i can say i need to delete a lot more commands on the Dell tablet then on the Surface on to get it to run.

  but when running above command with Java, the output video is not generated

  


  Java code

  


  @Test
public void generateVideo2() throws IOException, IOException {
    String fileNameFullPath= "/Users/test/video.mp4";
    String[] videoCmd = new String[]
            {"/bin/sh", "-c", "/opt/homebrew/Cellar/ffmpeg/5.1.2/bin/ffmpeg",

    Process processDuration = new ProcessBuilder().command(videoCmd).start();
    StringBuilder strBuild = new StringBuilder();
    try (BufferedReader processOutputReader = new BufferedReader(new InputStreamReader(processDuration.getInputStream(), Charset.defaultCharset()));) {

        }
        int i = processDuration.waitFor();
        System.out.println("Process exitValue: "+i);
    } catch (InterruptedException e) {
        throw new RuntimeException(e);
    }
}


  


  JAVA OUTPUT
