Question

I am facing a issue while generating a thumbnail image for small video.
I am using below code for thumbnail generation.

private Task CreateThumbnailImage(Bitmovin.Api.Sdk.Models.Encoding encoding, Stream stream, Output output, string outputPath)
{

        var sprite = new Sprite()
        {
            AspectMode = ThumbnailAspectMode.STRETCH,
            Name = "Thumbnail images",
            Unit = SpriteUnit.SECONDS,
            Outputs = new List<EncodingOutput>() { BuildEncodingOutput(output, "thumbnail") },
            Height = 100,
            Width = 100,
            ImagesPerFile = 10,
            CreationMode = SpriteCreationMode.INTERVAL_START,
            Distance = 10,
            SpriteName  = "thumb.png",
            Filename = "thubnailsprite.png",
            VttName = "thumbnail.vtt",
            Description = "This method will create a vtt file"

        };

        return _bitmovinApi.Encoding.Encodings.Streams.Sprites.CreateAsync(encoding.Id, stream.Id, sprite);

    }

Its not working for small video means where video runtime is 1 minute.

Sprite file name is thumb.png but in vtt file its using thumb-0.png please see below code snippet.

00:00:00.000 → 00:00:10.000
thumb-0.png#xywh=0,0,100,100

We need urgent help on this. Thanks in advance.

Hi @vinayak.baye
I created an internal engineering ticket for this issue. It will be picked up for an upcoming sprint but I can’t give you an ETA at this time.

Please keep an eye on our release notes at Encoder
