  • Encoding error with Sidekiq

    14 mars 2017, par DavidK

    Im following this tutorial https://www.pubnub.com/blog/2015-12-08-building-video-sharing-app-server-messaging-ruby/ on Building a Video Sharing App. Its a bit outdated and Ive already had to fix a view issues to get this far but Im pretty lost now with this latest issue. I believe its something to do with sidekiq. When I try uploading a video it seems to work and shows up on the database, but I get a "Video is still being encoded." message.

    This is the log :

[Parsed_concat_1 @ 0x7f922bc1cec0] Failed to configure output pad on   Parsed_concat_1
