FFMPEG recording in ASP.NET Core mvc application
19 avril 2020, par TimberI'm using ASP.NET Core and ffmpeg to record a live video stream. When the page receives a get request, the stream should begin recording and saving to a folder using ffmpeg. I want to make it so that when visiting the stop endpoint, the ffmpeg process is closed cleanly.



Unfortunately I'm unable to send a 'q' to stdin after leaving the Get method. Using taskkill requires the use of /F making the ffmpeg process (which is not a window) force quit and not save the video properly, resulting in a corrupt file.



I tried using
Process.Kill()but that results in a corrupt file as well. Also, I triedProcess.CloseMainWindow()which worked, but only when the process is started as a window, and I'm unable to start the process as a window in the server I'm using.


I've include the code I have so far below, so hopefully someone could lead me in the right path.



using System;
...
using Microsoft.Extensions.Logging;

namespace MyApp.Controllers
{
 [Route("api/[controller]")]
 [Authorize]
 public class RecordingController : Controller
 {
 private readonly ApplicationDbContext _context;
 private readonly ILogger<homecontroller> _logger;

 public RecordingController(ApplicationDbContext context, ILogger<homecontroller> logger)
 {
 _context = context;
 _logger = logger;
 }

 [HttpGet]
 public async Task<actionresult> Get()
 {

 // Define the os process
 var processStartInfo = new ProcessStartInfo()
 {
 // ffmpeg arguments
 Arguments = "-f mjpeg -i \"https://urlofstream.com/video.gci\" -r 5 \"wwwroot/video.mp4\"",
 FileName = "ffmpeg.exe",
 UseShellExecute = true
 };

 var p1 = Process.Start(processStartInfo);

 // p1.StandardInput.WriteLineAsync("q"); <-- This works here but not in the Stop method

 return Ok(p1.Id);
 }


 // GET: api/Recording/stop
 [HttpGet("stop/{pid}")]
 public ActionResult Stop(int pid)
 {
 Process processes = Process.GetProcessById(pid);
 processes.StandardInput.WriteLineAsync("q"); // Does not work, is not able to redirect input
 return Ok();
 }
 }
}


</actionresult></homecontroller></homecontroller>
