Problems about c# uses the VideoWriter class in dynamic link libraries(c++ and opencv) [closed]
11 mai 2023, par Paul_Dxerror : (-5:Bad argument) CAP_IMAGES : can't find starting number (in the name of file) : in function 'cv::icvExtractPattern'.


I used c++ and opencv to implement the video recording function, and then generated the code to dynamically link libraries for c# to call.But when I run the code, I get an error.


I have a general understanding that opencv calls the ffmpeg package(because of the videowriter class), so I import opencv_videoio_ffmpeg470_64.dll into the project.But the problem was not solved.

How to write a unit test class that creates a new process in C#
12 mars 2023, par IceAgeI have a question about how to write unit test method that creates a new process.


At the moment I write a normal unit test to create a process, but it's very difficult to setup.


This is my code I want to test.


using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.IO;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading.Tasks;

namespace xxx
{
 public class FFmPeg
 {
 private Process _process;
 private string ffmpegPath { get; set; }
 private Regex _durationRegex;

 public event EventHandler<string> OutputData;
 public event EventHandler<int> ProgressChange;

 public FFmPeg()
 {
 _process = new Process();
 ffmpegPath = Path.Combine(Directory.GetCurrentDirectory(), "engine", "ffmpeg.exe");
 }

 public void Run(string Argument)
 {
 _process.StartInfo.FileName = ffmpegPath;
 _process.StartInfo.Arguments = $"{Argument} -y";
 _process.StartInfo.UseShellExecute = false;
 _process.StartInfo.RedirectStandardOutput = true;
 _process.StartInfo.RedirectStandardError = true;
 _process.StartInfo.StandardOutputEncoding = Encoding.UTF8;
 _process.StartInfo.CreateNoWindow = true;
 _process.OutputDataReceived +=(o,e) =>
 {
 };
 _process.ErrorDataReceived += (o, e) =>
 {
 if (string.IsNullOrEmpty(e.Data) == false)
 {
 OnProgressChange(OutputExtractor.GetProgress(e.Data));
 }//end if.check data is not empty
 };

 _process.Start();
 _process.BeginOutputReadLine();
 _process.BeginErrorReadLine();
 _process.WaitForExit();
 } //end method

 protected virtual void OnProgressChange(int progress)
 {
 ProgressChange?.Invoke(this,progress);
 } //end method

 protected virtual void OnOutputData(string data)
 {
 OutputData?.Invoke(this, data);
 }
 }
}
</int></string>

Thanks for any helpful answers, and sorry for my English.

Reducing latency of FFmpeg audio stream using Opus encoding
28 septembre 2022, par Victor AlmeidaI'm trying to stream my microphone audio using FFmpeg, but there's a delay of about 3 seconds from when the audio is recorded to when it is played.


The snippet below contains the minimal command for which I can reproduce the problem.


ffmpeg -f dshow -i "audio=Microphone (Realtek(R) Audio)" -f opus - | ffplay -


However, I've tried various other flags to no effect. Such as :


- 

-analyzeduration 0-loglevel 0-audio_buffer_size 50-fflags nobuffer-flags low_delay-acodec libopus














Is there any way to reduce the latency to less than a second while still using Opus encoding ?
