Transcoding passes but video not uploaded (rollback transaction)

[zeronone]

I am using Rails 4.2. I have a ContentUploader for uploading images and videos. I am using carrierwave-video-thumbnailer for creating video thumbnails.

  version :mp4, :if => :video? do
    process encode_video: [:mp4, callbacks: { after_transcode: :set_is_converted } ]
  end

Following is the output:

I'm having the same problem. It's rolling back for no reason at all. I don't see anything in my server log that points to what's causing the rollback to occur.

I did a reinstall of the ffmpegthumbnailer and it worked fine afterwards for me.

Anyone resolved this problem instead of reinstalling ffmpegthumbnailer? I still have the error after the reinstall.
