• executing batch file when called from java project

  28 décembre 2013, par Mostafa Wasat

  So I'm working on a java project, that at some point I have to execute a batch file (from within the code).

  The batch file runs fine if I run it by double clicking in windows explorer,
  and/or even if I write the command in the command prompt it runs ok.

  However, when i call the file from the java code, the command prompt launches and says that its not a recognized command, program, or batch file.

  the patch file looks something like this :

  ffmpeg -re -i C:/001.mp3 -c:a mp3 -ar 12000 -f mulaw -f rtp rtp://127.0.0.1:1234

  and here's how I call it within the java code :

  Runtime.getRuntime().exec("cmd /c start c:\\encode.bat");

  I might add that the command prompt when run by java it runs as administrator and I have included the ffmpeg path to be run by any user anyway.

  Excuse me if I have missed any important details and would be happy to provide them if anyone needs further details to answer my dilemma.

  why might this be ?

  Edit :
  i have tried the same code on another pc and it works fine, can someone please explain to me why the command doesnt get recognized when the command prompt gets run through java

• Turn Mp4 File into Portrait Video

  5 avril 2022, par Tech Breaker

  I recently programmed a bot, which uses the Twitch API to scrape Twitch videos, and then post them on YouTube. This is my youtube channel if you want to see an example : https://www.youtube.com/channel/UCuhWw8LbPWdkybIF9olAszw

  


  The problem that I am having is I want to find a way to convert these regular twitch videos, into youtube shorts which I can automatically upload. The facecam does not need to be included, and the entire video can just be compressed into a 9:16 format.

  


  I already tried FFMPEG but I don't know if I am doing it correctly, and really need help or advice on how to do this.

  


  Here is an example of a video I would try to convert :

  (excuse the explicit language, this is just the first video I saw on my bot channel)

  


  Tldr : Convert mp4 file into a 9:16 video format

  


  EDIT :

  


  Command i ran : ffmpeg -i video.mp4 -vf scale=1280:720 output.mp4
