UploadThumbnailAsync not working?

[Onthrax]

Hi,

I've been having difficulties uploading a custom thumbnail to vimeo. Every attempt results in images like this: https://i.vimeocdn.com/video/786876502_480.jpg

I don't see anything wrong with the code but perhaps I am doing something wrong.
Or perhaps Vimeo has changed something.

Please assist.

Using file = New VimeoDotNet.Net.BinaryContent(FileUpload1.FileContent, "image/jpeg") Dim uploaded = Await Client.UploadThumbnailAsync(Record.VimeoClipID, file) End Using

Hi,
I have the same problem, thumbnails appear as Onthrax described.
I have tried with png, same results.
I have also tried to use a frame of the video by setting "time" as described here: https://developer.vimeo.com/api/upload/thumbnails#creating-a-thumbnail but always same result.

Anyone can help?
Thanks.

Update: I was encoding "active" and "time" in the url, instead they should be put in the body.
I have made the correction and now works, I can use a frame of the video as thumbnail without having to upload any file.

public async Task SetThumbnailAsync(long clipId, float time)
        {
            try
            {
                ThrowIfUnauthorized();
                var request = _apiRequestFactory.GetApiRequest(AccessToken);
                request.Method = HttpMethod.Post;
                request.Path = Endpoints.Pictures;
                request.UrlSegments.Add("clipId", clipId.ToString());
                var parameters = new Dictionary<string, string>
                {
                    ["active"] = "true",
                    ["time"] = time.ToString()
                };
                request.Body = new FormUrlEncodedContent(parameters);
                var response = await request.ExecuteRequestAsync().ConfigureAwait(false);
                CheckStatusCodeError(null, response, "Error Setting thumbnail image.");
            }
            catch (Exception ex)
            {
                if (ex is VimeoApiException)
                {
                    throw;
                }
                throw new VimeoUploadException("Error Setting thumbnail image.", null, ex);
            }
        }
