• Swift A script of macOS is not running on the M2 chip ?

  15 avril 2024, par Muhammad Danish Qureshi

  I am making a macOS app using SwiftUI, app is working fine on mac Intel chip, mac Apple M1 chip but not working on the mac M2 chip.
Below is the following code which is crashing on M2 chip for force unwrapping the data in String(data: data!, encoding: .utf8).

  


  I know that force unwrap is not suitable, but for testing purpose I am doing force unwrap.

  


  When I run the which ffmpeg in terminal it provides the path in result, no matter which mac terminal is (it always return actual path of ffmpeg), but when run this command from the swift Program it does not found anything and got crashed on apple M2 chip.

  


  My actual scenario (or requirement) is I need to get the path using the command which ffmpeg and write that path in the file on macOS app.

  


  Kindly guide me why the code is crashing or not providing the actual path.

  


  func findFFmpegPath() -> String? {
            let task = Process()
            task.launchPath = "/bin/bash" // Path to bash shell
            task.arguments = ["-l", "-c", "which ffmpeg"] // Execute "which ffmpeg" command
    let pipe = Pipe()
    task.standardOutput = pipe
    task.standardError = pipe // Capture any errors as well

    do {
        try task.run()
        let data = try pipe.fileHandleForReading.readToEnd()
        let output = String(data: data!, encoding: .utf8)
        print("data:\(data)\n\(output)\n\(output?.trimmingCharacters(in: .whitespacesAndNewlines))")
        return output?.trimmingCharacters(in: .whitespacesAndNewlines)
    } catch {
        print("Error running task: \(error)")
        return nil
    }
}


  


  When I run which ffmpeg in the terminal it gives me path correctly, See the screenshot bleow.

  


  

  


  When I run the /bin/bash -l -c "which ffmpeg" in the M2 than I got this result.

  


  

  


  When I run the /bin/bash -l -c "which ffmpeg" in the Apple M1 than I got this result.

  


  

  


  Getting desired result in the terminal, but not getting result from the Swift Program.

  


• Keep FFMPEG encoding session running [closed]

  14 décembre 2023, par APIS

  I am trying to encode an external HLS (m3u8) link into MPEG-TS over UDP via ffmpeg with this command :

  



  ffmpeg -re -i http://example.com/index400.m3u8 -vcodec copy -acodec copy -f mpegts udp://127.0.0.1:10000?pkt_size=1316


  



  Currently I am executing the command directly inside a terminal which I keep open on my Centos server. However, and after some time (volatile), I get the following error :

  



  


  Failed to resolve hostname example.com : Temporary failure in name resolution
  
 [hls,applehttp @ 0x349b420] Failed to reload playlist 0

  


  



  My question is, how can I run this command in a bash script or upstart or … so that whenever it unexpectedly stops, it automatically restarts.
I prefer not to use third parties like monit, and please be explicit in writing the script with annotation for newbies, I am not well experienced on this.

  


• Running ffplay video within a jframe

  22 juillet 2013, par Optimus Prime

  I wish to play a video in JFrame. I am already using ffmpeg in my project. As I wish to keep the project light, I am not willing to use other frameworks like JMF or other. I know that I can play video using ffplay. But the problem here is ffplay opens the video in new window when I try

  ffplay output.avi

  I wish to put that video within my JFrame, like a player. How can I do this ?

  Request :
  Please ask for any other clarifications, details, and suggest improvements or comment what you find wrong before downvoting or voting to close the question :). I will change it. I am really new to Java, I tried searching this but could not find any possible solution.

  What I tried ? I couln't find anything related to this, so I don't have any code. I am familiar to how to create frames, and can use runtime to ffplay video. But I got no clue how to put that video within my window :(.

  All suggestions are welcome if you can suggest me other methods to play the video. But I haven't use any frameworks other than ffmpeg. And do not wish to make the application heavier. So it would be more helpful if it can be achieved using ffplay.
