how to know video width, height, duration, bit_rate, checksum...

[hyperrjas]

I would like if it's possible to know this information.

This is my process encode_video:

process encode_video: [:mp4, resolution: "1280x720", callbacks: { after_transcode: :set_success } ]

Thanks!

carrierwave-video depends on this gem: https://github.com/streamio/streamio-ffmpeg

The encode_video method https://github.com/rheaton/carrierwave-video/blob/master/lib/carrierwave/video.rb#L42 is where you relevant changes would likely go.

Thanks, I would like set/send this info (duration, width, height...etc) to my model with a callback:

DEFAULTS = {
 callbacks: { after_transcode: :set_success },
 resolution: { 
    default: "1280x720"
  }
}
process :encode
def encode
  encode_video(:mp4, DEFAULTS) do |movie, params|
    params[:resolution][:default] = "1280x720"
  end
end

My question is, How can I set/send movie.duration or movie.width via callback to my model like :set_success method?

Thanks!

You'd need to make some changed to the gem.

Have a look at this pull request for some guidance: #18

I got some help and managed to do something like this for duration:
In your uploader class (my case 'VideoUploader < CarrierWave::Uploader::Base')

process :save_video_duration
.....
# then I have the version :mp4 ...
....
def save_video_duration
    video = FFMPEG::Movie.new(file.file).duration
    model.playTime = video
end
