Media Player SDK .NET vs FFmpeg .NET Wrappers

// NuGet: VisioForge.DotNet.MediaPlayer
using VisioForge.Core.MediaPlayer;

// Create engine and assign to a WPF/WinForms video view
var player = new MediaPlayerCoreX(videoView);

// Open a file and play
await player.OpenAsync(new Uri("video.mp4"));
await player.PlayAsync();

// Seek to 30 seconds
await player.Position_SetAsync(TimeSpan.FromSeconds(30));

// Adjust volume
player.Audio_OutputDevice_Volume_Set(0.75);

// Take a snapshot
await player.Snapshot_SaveAsync("frame.png");

// NuGet: FFMpegCore
using FFMpegCore;

// FFmpeg wrappers do NOT provide real-time playback.
// You can extract frames, but displaying them is your job.

// Extract a single frame at 30 seconds
await FFMpeg.SnapshotAsync("video.mp4", "frame.png",
    captureTime: TimeSpan.FromSeconds(30));

// For actual playback you would need to:
// 1. Pipe raw frames from ffmpeg stdout
// 2. Decode them in your app
// 3. Render each frame on a UI surface
// 4. Handle audio sync separately
// This is hundreds of lines of custom code.

// Play DVD with menu navigation
var player = new MediaPlayerCoreX(videoView);

var dvdSource = new DVDSource(new Uri("D:\\"));
await player.OpenAsync(dvdSource);
await player.PlayAsync();

// Navigate DVD menu
player.DVD_Menu_Show();
player.DVD_Menu_SelectButton(2);
player.DVD_Menu_ActivateButton();

// Switch audio track or subtitle
player.DVD_AudioStream_Set(1);
player.DVD_SubtitleStream_Set(0);

// FFmpeg has limited DVD support.
// No menu navigation is possible.

// You can rip a specific title:
// ffmpeg -i "dvd://1" -c:v libx264 output.mp4

// With FFMpegCore:
await FFMpegArguments
    .FromFileInput("D:\\VIDEO_TS")
    .OutputToFile("output.mp4", overwrite: true, options => options
        .WithVideoCodec("libx264")
        .WithAudioCodec("aac"))
    .ProcessAsynchronously();

// No interactive menu, no subtitle toggle,
// no chapter navigation during playback.

// Apply audio effects in real time
var player = new MediaPlayerCoreX(videoView);
await player.OpenAsync(new Uri("concert.mp4"));
await player.PlayAsync();

// 10-band equalizer
player.Audio_Equalizer_Enable(true);
player.Audio_Equalizer_Band_Set(0, 6.0);   // 60 Hz boost
player.Audio_Equalizer_Band_Set(9, -3.0);  // 16 kHz cut

// Add reverb effect
player.Audio_Effects_Enable(true);
player.Audio_Effects_Reverb(0.5, 0.3);

// Audio effects require re-encoding the file.
// No real-time adjustment is possible.

await FFMpegArguments
    .FromFileInput("concert.mp4")
    .OutputToFile("concert_eq.mp4", overwrite: true, options => options
        .WithAudioFilters(af => af
            .Argument("superequalizer=1b=6:10b=-3")
            .Argument("aecho=0.8:0.88:60:0.4")))
    .ProcessAsynchronously();

// This creates a new file.
// Want to tweak the EQ? Re-encode again.
// Processing time depends on file length.
