aarch64 : vvc : Fix compilation of alf.S with MSVC 2022 17.7 and older
23 juillet 2024, par Martin Storsjöaarch64 : vvc : Fix compilation of alf.S with MSVC 2022 17.7 and older
Use the "ldur" instruction explicitly, instead of having the
assembler implicitly convert "ldr" instructions to "ldur".This fixes build errors like these :
libavcodec\aarch64\vvc\alf.o.asm(1023) : error A2518 : operand 2 : Memory offset must be aligned
ldr q22, [x3, #24]
libavcodec\aarch64\vvc\alf.o.asm(1024) : error A2518 : operand 2 : Memory offset must be aligned
ldr q24, [x2, #24]
libavcodec\aarch64\vvc\alf.o.asm(1393) : error A2518 : operand 2 : Memory offset must be aligned
ldr q22, [x3, #24]
libavcodec\aarch64\vvc\alf.o.asm(1394) : error A2518 : operand 2 : Memory offset must be aligned
ldr q24, [x2, #24]Signed-off-by : Martin Storsjö <martin@martin.st>

C# server problem with FFmpeg Visual Studio 2022
16 mai 2024, par seanofdeadHello everyone I've spent countless hours on my server I'm trying to create that will share video from one stream to another client computer. That is the goal anyway. I'm using Visual Studio 2022 most recent update. Currently this is my code


using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Threading.Tasks;
using FFmpeg.AutoGen;
using NLog;

public class VideoStreamServer
{
 private const int Port = 5000;
 private TcpListener server;
 private FFmpegVideoEncoder encoder;
 private static readonly Logger logger = LogManager.GetCurrentClassLogger();

 public VideoStreamServer()
 {
 // Initialize FFmpeg network components
 Console.WriteLine("Initializing FFmpeg network components...");
 int result = ffmpeg.avformat_network_init();
 if (result != 0)
 {
 throw new ApplicationException($"Failed to initialize FFmpeg network components: {result}");
 }

 // Initialize encoder
 encoder = new FFmpegVideoEncoder(1920, 1080, AVCodecID.AV_CODEC_ID_H264); // Screen size & codec
 }

 public static void Main()
 {
 // Initialize NLog
 var logger = LogManager.GetCurrentClassLogger();
 logger.Info("Application started");

 var server = new VideoStreamServer();
 server.Start().Wait();
 }

 public async Task Start()
 {
 server = new TcpListener(IPAddress.Any, Port);
 server.Start();
 logger.Info($"Server started on port {Port}...");

 try
 {
 while (true)
 {
 TcpClient client = await server.AcceptTcpClientAsync();
 logger.Info("Client connected...");
 _ = HandleClientAsync(client);
 }
 }
 catch (Exception ex)
 {
 logger.Error(ex, "An error occurred");
 }
 }

 private async Task HandleClientAsync(TcpClient client)
 {
 using (client)
 using (NetworkStream netStream = client.GetStream())
 {
 try
 {
 await encoder.StreamEncodedVideoAsync(netStream);
 }
 catch (IOException ex)
 {
 logger.Error(ex, $"Network error: {ex.Message}");
 // Additional logging and recovery actions
 }
 catch (Exception ex)
 {
 logger.Error(ex, $"Unexpected error: {ex.Message}");
 // Log and handle other exceptions
 }
 finally
 {
 // Ensure all resources are cleaned up properly
 client.Close();
 logger.Info("Client connection closed properly.");
 }
 }
 }
}

public class FFmpegVideoEncoder
{
 private readonly int width;
 private readonly int height;
 private readonly AVCodecID codecId;
 private static readonly Logger logger = LogManager.GetCurrentClassLogger();

 public FFmpegVideoEncoder(int width, int height, AVCodecID codecId)
 {
 this.width = width;
 this.height = height;
 this.codecId = codecId;
 InitializeEncoder();
 }

 private void InitializeEncoder()
 {
 // Initialize FFmpeg encoder here
 logger.Debug("FFmpeg encoder initialized");
 }

 public async Task StreamEncodedVideoAsync(NetworkStream netStream)
 {
 // Initialize reusable buffers for efficiency
 byte[] buffer = new byte[4096];

 // Capture and encode video frames
 while (true)
 {
 try
 {
 // Simulate capture and encoding
 byte[] videoData = new byte[1024]; // This would come from the encoder

 // Simulate streaming
 for (int i = 0; i < videoData.Length; i += buffer.Length)
 {
 int chunkSize = Math.Min(buffer.Length, videoData.Length - i);
 Buffer.BlockCopy(videoData, i, buffer, 0, chunkSize);
 await netStream.WriteAsync(buffer, 0, chunkSize);
 }
 }
 catch (Exception ex)
 {
 logger.Error(ex, "Error streaming video data");
 throw; // Rethrow to handle in the calling function
 }

 await Task.Delay(1000 / 30); // For 30 FPS
 }
 }
}


When I build no issues but when i run it in debug mode I get this error


System.DllNotFoundException
 HResult=0x80131524
 Message=Unable to load DLL 'avformat.59 under C:\Users\phlfo\Downloads\cfolder\server\ConsoleApp\bin\Debug\': The specified module could not be found.
 Source=FFmpeg.AutoGen
 StackTrace:

 at FFmpeg.AutoGen.ffmpeg.<>c.<.cctor>b__7_0(String libraryName)
 at FFmpeg.AutoGen.ffmpeg.<>c.<.cctor>b__7_242()

 at VideoStreamServer.Main() in C:\Users\phlfo\Downloads\cfolder\server\ConsoleApp\Program.cs:line 36


I have FFmpeg.AutoGen package installed through VS i originally started with 7.0 but then switched to 5.0 to see if an older version might work (it did not). I also have the files in the same directory as the .exe for testing purposes as seen in the screenshot. Can someone please help me figure out this error.
