get some metadata about a video file

Question

Hi,

I am currently working on a rails application in which the user upload a video file on the server, after what I send it to S3 where it's encoded by another service.

The thing is that before uploading it to S3 I need to know the quality of this file, the resolution, the bitrate, ...

I saw that the rvideo gem can do that but I'd like to avoid having to install ffmpeg on my rails server.

So my question is do you see a way to do that without much dependency ?

Thanks,

UPDATE: I also saw 2 gems wrapping the MediaInfo CLI but same problem I'd like to avoid installing MediaInfo CLI on my rails servers

Answer 1

You should be able to use the inspect command available in unix. I know paperclip uses it with their photo processing.
