Transcoding progress

How i can control progress in percents of large file transcoding ?

There is currently not a method for doing this in this gem.

It shouldn't be too hard to implement for normal streamio transcoding if you wanted to pass a block as an option to :encode_video

Here is how you pass the block: https://github.com/streamio/streamio-ffmpeg#transcoding

You would add it to the options and if it's set, execute it here: https://github.com/rheaton/carrierwave-video/blob/master/lib/carrierwave/video.rb#L57

Here's an example of how it might look in the end:

class VideoUploader < CarrierWave::Uploader::Base
  include CarrierWave::Video

  process encode_video: [:mp4, { progress_block: Proc.new {|progress| puts progress} } ]
end

If you wanted it to send a method to the object with the uploader, you'd have to check that the scope worked out. That might look like this:

class VideoUploader < CarrierWave::Uploader::Base
  include CarrierWave::Video

  process encode_video: [:mp4, { callbacks: { progress: :progress_method } ]
end

I can't remember if the ffmpeg2theora binary gives any progress as I'm not actively developing this anymore.
