How to make FFmpeg download only the required segments [closed]
25 juillet, par daniil_I'm developing a tool, that create timelapse. For this purpose I use ffmpeg 7.1.1 verion.
I have a playlist file called index.m3u8 (inside it there are URLs to TS segments—typically around 5,000 of them). Here’s a small excerpt :

I’m trying to extract still images from the stream at specific moments.


When I run a command like :


ffmpeg \
 -analyzeduration 5000000 \
 -probesize 5000000 \
 -err_detect ignore_err \
 -protocol_whitelist file,http,https,tcp,tls \
 -allowed_extensions ALL \
 -f hls \
 -y \
 -ss 11316.719 \
 -i /Users/daniil/Desktop/test/exports/.../index.m3u8 \
 -frames:v 1 \
 -q:v 2 \
 /Users/daniil/Desktop/test/exports/.../frames/frame_00100.png


ffmpeg downloads segments 1 and 2 (presumably to probe the format), and then it downloads two more TS files around the target timestamp.


But as soon as I push the -ss value beyond a certain point—in my case -ss 8487.54—it starts downloading every TS segment from the very start of the playlist up to the one I need. That can easily be 1,000 TS files or more. In other words, when -ss is between 0 and 8374.372, everything works fine, but beyond that it exhibits this strange behavior.

exe file not executing from deployed ASP.NET MVC app in TAS (Tanzu /PCF)
24 juin, par Darshan AdakaneI 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_buildpackand storing the file inPath.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
.exeis 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]
[Route("uploadimage")]
public async Task<ihttpactionresult> UploadImage()
{
 try
 {
 if (!Request.Content.IsMimeMultipartContent())
 return BadRequest("Unsupported media type.");

 Console.WriteLine("UploadImage method started.");

 var provider = new MultipartMemoryStreamProvider();
 await Request.Content.ReadAsMultipartAsync(provider);

 Console.WriteLine($"Total Files available: {provider.Contents.Count}, {provider.Contents}");

 foreach (var file in provider.Contents)
 {
 try
 {
 var imageFile = await file.ReadAsByteArrayAsync();
 Console.WriteLine($"imageFile, { imageFile.Length }");
 var rawFileName = file.Headers.ContentDisposition.FileName.Trim('"');
 Console.WriteLine($"rawFileName, {rawFileName}");
 var fileName = Path.GetFileName(rawFileName); // Sanitize filename
 Console.WriteLine($"fileName, {fileName}");

 // Check file size limit (300MB)
 if (imageFile.Length > 300 * 1024 * 1024) // 300MB limit
 {
 Console.WriteLine("File size exceeds 300MB limit.");
 return BadRequest("File size exceeds 300MB limit.");
 }

 var inputFilePath = Path.Combine(_uploadFolder, fileName);
 Console.WriteLine($"inputFilePath, {inputFilePath}");

 var outputFilePath = Path.Combine(_uploadFolder, "compressed_" + fileName);
 Console.WriteLine($"outputFilePath, {outputFilePath}");

 // Save uploaded file to disk
 File.WriteAllBytes(inputFilePath, imageFile);

 // Check if the input file exists
 if (!File.Exists(inputFilePath))
 {
 Console.WriteLine($"Input file does not exist: {inputFilePath}");
 return InternalServerError(new Exception($"❌ Input file does not exist: {inputFilePath}"));
 }

 //Console.WriteLine($"✅ FFmpeg found at path: {ffmpegFullPath}");

 await FFMpegArguments
 .FromFileInput(inputFilePath)
 .OutputToFile(outputFilePath, overwrite: true, options => options
 .WithCustomArgument("-vf scale=800:-1")
 .WithCustomArgument("-q:v 10")
 )
 .ProcessAsynchronously();

 Console.WriteLine($"outputFilePath, {outputFilePath}");

 // Check if the output file was created
 if (File.Exists(outputFilePath))
 {
 var fileInfo = new FileInfo(outputFilePath); // Get file info

 Console.WriteLine($"outputFileInfoPropsFullName, {fileInfo.FullName}");
 Console.WriteLine($"outputFileInfoPropsLength, {fileInfo.Length}");

 var compressedFileBytes = File.ReadAllBytes(outputFilePath);
 var compressedFileBase64 = Convert.ToBase64String(compressedFileBytes);

 return Ok(new
 {
 Message = "Image uploaded and compressed successfully.",
 CompressedImagePath = outputFilePath,
 CompressedFileSize = fileInfo.Length, // Size in bytes
 CompressedFileBase64 = compressedFileBase64
 });
 }
 else
 {
 Console.WriteLine("OutputFilePath File not exists.");
 return InternalServerError(new Exception($"❌ Failed to create compressed file: {outputFilePath}"));
 });
 }
 catch (Exception ex)
 {
 Console.WriteLine($"File TRYCATCH:{ex}");
 return InternalServerError(new Exception("Image compression failed: " + ex.Message));
 }
 }
 }
 catch (Exception ex)
 {
 Console.WriteLine($"Method TRYCATCH:{ex}");
 throw;
 }

 return BadRequest("No image file uploaded.");
}
</ihttpactionresult>

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


await FFMpegArguments


This is the exception log :


FFMpegCore.Exceptions.FFMpegException: ffmpeg was not found on your system


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

My objective is to run successfully exe on TAS and image compression to happen.

Is this a problem in my command, the stream, or FFMPEG itself ? [closed]
10 juin, par Ali MustafaI 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 ?
