Emballe Médias : Mettre en ligne simplement des documents
29 octobre 2010, parLe plugin emballe médias a été développé principalement pour la distribution mediaSPIP mais est également utilisé dans d’autres projets proches comme géodiversité par exemple. Plugins nécessaires et compatibles
Pour fonctionner ce plugin nécessite que d’autres plugins soient installés : CFG Saisies SPIP Bonux Diogène swfupload jqueryui

Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
Types de fichiers supportés dans les flux
Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...) -
Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

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();
 }
 }
}

Wrong Bitrate after ffmpeg WAV to MP3 Conversion
