  • FFmpeg RTSP stream to remote MediaMTX server disconnects after a few seconds [closed]

    13 juin, par Rorschy

    I'm new to RTSP and MediaMTX, and I'm trying to live stream my screen using FFmpeg and MediaMTX for a specific use case.

    


    Everything works perfectly when both FFmpeg and MediaMTX run on the same machine.
However, when I move MediaMTX to a remote server, the stream becomes unstable — I can't maintain a connection or view the stream reliably.

    


    Here is the FFmpeg command I'm using from the client machine :

    


    ffmpeg -f gdigrab -framerate 10 -offset_x 0 -offset_y 0 -video_size 1920x1080 -i desktop -f lavfi -i anullsrc -vcodec libx264 -tune zerolatency -g 30 -sc_threshold 0 -preset ultrafast -tune zerolatency -f rtsp rtsp:///live/stream


    


    And here’s the relevant MediaMTX log output on the remote server :

    My questions :

    


      

    1. What could be causing the RTSP stream to disconnect when streaming to a remote MediaMTX server ?

      2. 


    2. Are there any recommended network settings or MediaMTX configuration tweaks to ensure a stable stream over the internet ?

      3. 


    


    Any help or guidance would be greatly appreciated. Thanks !

    


  • Is this a problem in my command, the stream, or FFMPEG itself ? [closed]

    10 juin, par Ali Mustafa

    I am trying to download a section from approximately 06:40:00 to 06:44:00 from this stream : https://kick.com/grossgore/videos/8d36c089-ff2b-4167-9c92-bc8a3a9d033b

    


    I found the m3u8 URL : https://stream.kick.com/ivs/v1/196233775518/hDSBAWziz2jA/2025/5/25/12/56/LrW3TwZUg7Xk/media/hls/1080p60/playlist.m3u8

    


    I run the following command :

    


    ffmpeg -ss 06:40:00 -to 06:44:00 -i https://stream.kick.com/ivs/v1/196233775518/hDSBAWziz2jA/2025/5/25/12/56/LrW3TwZUg7Xk/media/hls/1080p60/playlist.m3u8 -c copy out.mp4


    


    The command runs for a while, but for some reason the output file is empty once the program has finished. How do I figure out what the problem is ?

  • exe file not executing from deployed ASP.NET MVC app in TAS (Tanzu /PCF)

    24 juin, par Darshan Adakane

    I am facing an issue for my ASP.NET MVC web application on .NET 4 being deployed to TAS.

    


    I am trying to do image compression using ffmpeg.exe.

    


    While it is working on my local machine, I get an "500 internal server error" when deployed to TAS (tanzu application server). I am using hwc_buildpack and storing the file in Path.GetTemp() folder for testing.

    


    applications:
- name: MyApp-Dev
  memory: 1G
  instances: 1
  stack: windows
  buildpacks:
    - hwc_buildpack
  path: \MyAppnew\obj\Release\Package\PackageTmp
  env:
  services:
  routes:
    - route: myapp-dev.apps.company.com
    - route: myapp-dev.company.com


    


    I also see that the .exe is being published when app I deployed. I am assuming if TAS has NO permission to read exe or read exe 'not allowed' policy.

    


    This is my code :

    


    [HttpPost]&#xA;[Route("uploadimage")]&#xA;public async Task<ihttpactionresult> UploadImage()&#xA;{&#xA;    try&#xA;    {&#xA;        if (!Request.Content.IsMimeMultipartContent())&#xA;            return BadRequest("Unsupported media type.");&#xA;&#xA;        Console.WriteLine("UploadImage method started.");&#xA;&#xA;        var provider = new MultipartMemoryStreamProvider();&#xA;        await Request.Content.ReadAsMultipartAsync(provider);&#xA;&#xA;        Console.WriteLine($"Total Files available: {provider.Contents.Count}, {provider.Contents}");&#xA;&#xA;        foreach (var file in provider.Contents)&#xA;        {&#xA;            try&#xA;            {&#xA;                var imageFile = await file.ReadAsByteArrayAsync();&#xA;                Console.WriteLine($"imageFile, { imageFile.Length }");&#xA;                var rawFileName = file.Headers.ContentDisposition.FileName.Trim(&#x27;"&#x27;);&#xA;                Console.WriteLine($"rawFileName, {rawFileName}");&#xA;                var fileName = Path.GetFileName(rawFileName); // Sanitize filename&#xA;                Console.WriteLine($"fileName, {fileName}");&#xA;&#xA;                // Check file size limit (300MB)&#xA;                if (imageFile.Length > 300 * 1024 * 1024) // 300MB limit&#xA;                {&#xA;                    Console.WriteLine("File size exceeds 300MB limit.");&#xA;                    return BadRequest("File size exceeds 300MB limit.");&#xA;                }&#xA;&#xA;                var inputFilePath = Path.Combine(_uploadFolder, fileName);&#xA;                Console.WriteLine($"inputFilePath, {inputFilePath}");&#xA;&#xA;                var outputFilePath = Path.Combine(_uploadFolder, "compressed_" &#x2B; fileName);&#xA;                Console.WriteLine($"outputFilePath, {outputFilePath}");&#xA;&#xA;                // Save uploaded file to disk&#xA;                File.WriteAllBytes(inputFilePath, imageFile);&#xA;&#xA;                // Check if the input file exists&#xA;                if (!File.Exists(inputFilePath))&#xA;                {&#xA;                    Console.WriteLine($"Input file does not exist: {inputFilePath}");&#xA;                    return InternalServerError(new Exception($"❌ Input file does not exist: {inputFilePath}"));&#xA;                }&#xA;&#xA;                //Console.WriteLine($"✅ FFmpeg found at path: {ffmpegFullPath}");&#xA;&#xA;                await FFMpegArguments&#xA;                .FromFileInput(inputFilePath)&#xA;                .OutputToFile(outputFilePath, overwrite: true, options => options&#xA;                    .WithCustomArgument("-vf scale=800:-1")&#xA;                    .WithCustomArgument("-q:v 10")&#xA;                    )&#xA;                    .ProcessAsynchronously();&#xA;&#xA;                Console.WriteLine($"outputFilePath, {outputFilePath}");&#xA;&#xA;                // Check if the output file was created&#xA;                if (File.Exists(outputFilePath))&#xA;                {&#xA;                    var fileInfo = new FileInfo(outputFilePath); // Get file info&#xA;&#xA;                    Console.WriteLine($"outputFileInfoPropsFullName, {fileInfo.FullName}");&#xA;                    Console.WriteLine($"outputFileInfoPropsLength, {fileInfo.Length}");&#xA;&#xA;                    var compressedFileBytes = File.ReadAllBytes(outputFilePath);&#xA;                    var compressedFileBase64 = Convert.ToBase64String(compressedFileBytes);&#xA;&#xA;                    return Ok(new&#xA;                    {&#xA;                        Message = "Image uploaded and compressed successfully.",&#xA;                        CompressedImagePath = outputFilePath,&#xA;                        CompressedFileSize = fileInfo.Length, // Size in bytes&#xA;                        CompressedFileBase64 = compressedFileBase64&#xA;                    });&#xA;                }&#xA;                else&#xA;                {&#xA;                    Console.WriteLine("OutputFilePath File not exists.");&#xA;                    return InternalServerError(new Exception($"❌ Failed to create compressed file: {outputFilePath}"));&#xA;                });&#xA;            }&#xA;            catch (Exception ex)&#xA;            {&#xA;                Console.WriteLine($"File TRYCATCH:{ex}");&#xA;                return InternalServerError(new Exception("Image compression failed: " &#x2B; ex.Message));&#xA;            }&#xA;        }&#xA;    }&#xA;    catch (Exception ex)&#xA;    {&#xA;        Console.WriteLine($"Method TRYCATCH:{ex}");&#xA;        throw;&#xA;    }&#xA;&#xA;    return BadRequest("No image file uploaded.");&#xA;}&#xA;</ihttpactionresult>

    &#xA;

    I'm getting this error in my tanzu environment logs from the code when I execute :

    &#xA;

     await FFMpegArguments&#xA;

    &#xA;

    This is the exception log :

    &#xA;

    FFMpegCore.Exceptions.FFMpegException: ffmpeg was not found on your system&#xA;

    &#xA;

    I also see that the .exe files do exist in TAS in these logs :

    &#xA;
