Hi, Wojtek here with the summary of changes from the last week.
It extracts duration and bit rate of audio files and stores it in the record metadata column.
The metadata attribute of video blobs has a new boolean key named audio that is set to true if the file has an audio channel and false if it doesn’t.
Returns attributes with values for assignment to the database. It works both for Active Record and Active Model objects.
More work on improving performance by eliminating class variables. This is a followup to previous change where detailed benchmark can be found.
