Error: decodeVideoFrame() failed: frame not finished

[VVatashi]

Hi,

I unable to create a thumbnail using ffmpegthumbnailer for the following file: https://lewd.ga/test/src/1555561354527.mp4

I'm trying to do:
ffmpegthumbnailer -s 250 -t 00:00:01 -i src/1555561354527.mp4 -o thumb/1555561354527s.jpg
And it creates empty file and outputs this error:
Error: decodeVideoFrame() failed: frame not finished

I'm using ffmpegthumbnailer 2.1.1 on debian 9.6

However I can create a thumbnail without problems using ffmpeg directly:

ffmpeg -y -ss 00:00:01 -i src/1555561354527.mp4 -vframes 1 -vf scale=w=250:h=250:force_original_aspect_ratio=decrease thumb/1555561354527s.jpg

Same error with this file: https://gitlab.xfce.org/xfce/tumbler/uploads/ac9ce7245447ff8e170ee70577f85c82/opus_WITH_COVER.mkv

I can't create a thumbnail with the above command though.
