• Is it possible to adjust position of gdigrab recording region during recording ?

  30 novembre 2020, par adelima

  I'm using ffmpeg for recording video from defined desktop region by starting ffmpeg.exe as process with arguments like so :

  


      public static void StartRecording(Video v) {
        string outPath = Path.Combine(Application.StartupPath, "rec", $"{v.FileName}.mkv");
        v.FFMPEG = new Process {
            StartInfo = new ProcessStartInfo() {
                Arguments = $"-hide_banner -y -thread_queue_size 512 -f gdigrab -offset_x {v.Bounds.X} -offset_y {v.Bounds.Y} -video_size {v.Bounds.Width}x{v.Bounds.Height} -show_region 0 -i desktop -vf \"scale=trunc(iw/2)*2:trunc(ih/2)*2\" -c:v libx264 -preset ultrafast -crf 18 -pix_fmt yuv420p \"{outPath}\"",
                WindowStyle = ProcessWindowStyle.Hidden,
                CreateNoWindow = true,
                UseShellExecute = false,
                FileName = Path.Combine(Application.StartupPath, "bin", "ffmpeg.exe"),
                RedirectStandardOutput = true,
                RedirectStandardInput = true,
                RedirectStandardError = true,
            }
        };
        v.FFMPEG.Start();

        new Thread(() => {
            using(StreamReader sr = v.FFMPEG.StandardError) {
                while(!sr.EndOfStream) {
                    Debug.WriteLine(sr.ReadLine());
                }
            }
        }).Start();
    }

    public static void StopRecording(Video v) {
        using(StreamWriter sw = v.FFMPEG.StandardInput) {
            sw.WriteLine("q\n");
        }
        v.FFMPEG.WaitForExit();
        v.FFMPEG.Dispose();
    }


  


  Is it possible to make changes to the -offset_x and -offset_y arguments during recording ? I'm drawing the recording region bounds with directx and want to add a titlebar to it which can be dragged to move the recording region, but I'm not sure how I would let ffmpeg know that I want these offsets changed or whether it's even possible.

  


• How do I fix this error in Python : RuntimeWarning : Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

  11 mars 2023, par Mason Griffith

  I have been trying to mess around with some of Eleven Labs API and make a simple program that takes in a string and can use the API to retrun a voice provided by Eleven Labs speaking the string. I've seen people using similar code to this but I always get the same error telling me it couldnt find ffmpeg or avconv. Any help would be grealty appreciated. Here is the code below.

  


  from elevenlabslib import *
import pydub
import pydub.playback
import io


def play(bytesData):
    sound = pydub.AudioSegment.from_file_using_temporary_files(io.BytesIO(bytesData))
    pydub.playback.play(sound)
    return


user = ElevenLabsUser("API_KEY")  # fill in your api key as a string
voice = user.get_voices_by_name("Rachel")[0]  # fill in the name of the voice you want to use. ex: "Rachel"
play(voice.generate_audio_bytes("Test"))  # fill in what you want the ai to say as a string


  


  Ive downloaded all the suggested packages and downloaded ffmpeg for windows but nothing has worked yet. I can see that the request is going through to the Eleven Labs website as my requested string pops up in my history on Eleven Labs but because of the error no audio is returned.
