It seems to be something related to paths, but I have tried EVERYTHING in my knowledge to fix this, still no luck... spent the majority of the day on it, no luck... so StackOverflow here I come !


My code :


public static async Task AddSubtitlesToVideoAsync(string videoPath, string subtitlesPath, string outputPath)
 {
 if (File.Exists(videoPath) && File.Exists(subtitlesPath))
 {
 //string subtitlesPathForwardSlashes = subtitlesPath.Replace("\\", "/");
 //string ffmpegCommand = $"-i \"{videoPath}\" -filter_complex \"subtitles='{subtitlesPathForwardSlashes}'\" \"{outputPath}\"";
 //string ffmpegCommand = $"-i \"{videoPath}\" -vf subtitles={subtitlesPathForwardSlashes} \"{outputPath}\"";
 //string ffmpegCommand = $"-i \"{videoPath}\" -vf subtitles=\"{subtitlesPath}\" \"{outputPath}\"";
 string subtitlesPathEscaped = subtitlesPath.Replace("\\", "\\\\");
 string ffmpegCommand = $"-i \"{videoPath}\" -vf subtitles=\"{subtitlesPathEscaped}\" \"{outputPath}\"";

 }
 else
 {
 Console.WriteLine("Files can't be found.");
 }

Apache Tika 2.0.9 programm ffmpeg and exiftool not found ?
6 avril 2024, par mj44I use an JavaFX Maven Project to use Apache Tika Version 2.9.0.
The Java Test program will be finished and all methods that I create will done right.
I have in the log file a lot of DEBUG errors and Idon't know why ?
I habe spent many hours to clear the problem.


Here's an excerpt of the logfile


2024-04-03 14:56:12 [main] DEBUG org.apache.tika.parser.external.ExternalParser - exception trying to run ffmpeg

The message says that ffmpeg and exiftool are not found.


This is my tika-config.xml

I tested the path of the programms in a console ant it worked fine ?
I don't know what I can do now ?


Thanks for Help


I have downloaded new copies of the ffmpeg and exiftool and installed them.
I tested it in a console to run and both tools work fine.
I tested the permissions, no problems with permissions
I tested that the tika-config.xml will be loaded, it loaded.
