Thumbnail size

[arc95]

Hi @yagotome. Great library! Is it possible to set the thumbnail size when you call this?

var options = new ConversionOptions { Seek = TimeSpan.FromSeconds(15) };
await ffmpeg.GetThumbnailAsync(inputFile, outputFile, options);

Thanks.

Hi @arc95!
There are already conversion parameters for your task, but (!) they are not considered in the GetThumbNailAsync function. :(

var thumbNail = await ffmpeg.GetThumbnailAsync(output, thumbNailFile, new ConversionOptions {
    CustomHeight = 100,
    CustomWidth = 100,
    VideoSize = Enums.VideoSize.Custom,
    Seek = TimeSpan.FromSeconds(3)
});

If you know all the ffmpeg parameters you can adjust FFmpegArgumentBuilder.GetThumbnail(MediaFile inputFile, MediaFile outputFile, ConversionOptions conversionOptions) and create a pull request.
I'd love to merge that one!

Just implemented it myself.
Have fun with version 3.3.0 and thumbnail sizes/cropping/aspect ratios! :)
