"File doesn't exist" - streamio FFMPEG on screenshot after create method
3 mai 2013, par dodgerogers747I have videos being directly uploaded to S3 using Amazon's CORS configuration. Videos are uploaded via a dedicated S3 form, once they have been uploaded successfully the URL of the video is appended to the @video.file hidden_field via javascript and then the video saves.
I can't get this
after_save
method to work which takes a screenshot of the video and saves it to S3 via carrierwave after the video has been saved as a rails object. ( It was previously working using a carrierwave video upload instance )It errors out with
Errno::ENOENT - No such file or directory - the file 'http://bucket-name.s3.amazonaws.com/uploads/video/file/secure-random-hex/video_name.m4v' does not exist:
I have tried running this method as a class method to call it from the console but it always comes back with the same error, even though the video exists.My bucket is set to public, read and write. How come it doesn't think the file exists ?
If anyone needs more code just shout, thanks in advance.
