如何使用 C#/.NET 的 FFmpeg 包装器从 .h264 转换为 .ts？

Question

Context

I'm using FFMpegCore in my .NET Core API project that receives a .h264 file (sent in a binary format that is received and converted into a byte array ) to be converted to a .ts .

I want to convert a .h264 stream into a .ts output stream using FFmpeg.

Current Approach

(...)

byte[] body;
using ( var ms = new MemoryStream() )
{
    await request.Body.CopyToAsync( ms ); // read sent .h264 data
    body = ms.ToArray();
}

var outputStream = new MemoryStream();

// FFMpegCore
await FFMpegArguments
                .FromPipeInput( new StreamPipeSource( new MemoryStream( body ) ) )
                .OutputToPipe( new StreamPipeSink( outputStream ), options => options
                .ForceFormat( VideoType.MpegTs ) )
                .ProcessAsynchronously();

// view converted ts file
await File.WriteAllBytesAsync( "output.ts", outputStream.ToArray() );

(...)

Problem

I'm not getting a working .ts file. What I'm a doing wrong? Could you please give some hint or help me with this? Even if you have other FFmpeg wrappers that you consider more suitable for this problem.

Notes:

• I don't have the physical location of the files since this will receive the content of the files over HTTP. So, I will only have the byte array meaning that I need to use the input stream to convert to another format.
• FFmpeg command used to test the conversion from .h264 to .ts (using files): ffmpeg -i file.h264 -an -vcodec copy -f mpegts output.ts

Missing the following argument: .WithVideoCodec( "h264" ) on FFMpegArguments .

(...)

byte[] body;
using ( var ms = new MemoryStream() )
{
    await request.Body.CopyToAsync( ms ); // read sent .h264 data
    body = ms.ToArray();
}

var outputStream = new MemoryStream();

// FFMpegCore
await FFMpegArguments
                .FromPipeInput( new StreamPipeSource( new MemoryStream( body ) ) )
                .OutputToPipe( new StreamPipeSink( outputStream ), options => options
                .WithVideoCodec( "h264" ) // added this argument
                .ForceFormat( "mpegts" ) ) // or VideoType.MpegTs
                .ProcessAsynchronously();

// view converted ts file
await File.WriteAllBytesAsync( "output.ts", outputStream.ToArray() );
