Reel

[pietrop]

What would be the best way to get direct access to the reel metadata? I can see it in the Ffprober object reel_name=>"NO NAME" but not quiet sure how to access it..

require "ffprober"
ffprobe = Ffprober::Parser.from_file("Clip15.mov")

any suggestions much appreciated

hey

thanks for the report, is it possible for you to share Clip15.mov? this would make it easier for me to look into this.

Thanks Ben, Meanwhile I figured out I can get to reel_name with a system call to ffprobe, but I'd rather use ffprober to keep it simple if there's a way..

require 'json'

clip_name="Clip15.mov"

# REEL_NAME
# use system call to save output of ffprobe as json  | from https://gist.github.com/nrk/2286511
ffprobe_json = `ffprobe -v quiet -print_format json -show_format -show_streams '#{clip_name}'`

#transform json into ruby hash from https://hackhands.com/ruby-read-json-file-hash/
data_hash = JSON.parse(ffprobe_json)
# access reel_name value in ruby hash / ffprobe json
reel_name = data_hash['streams'][2]["tags"]["reel_name"]

puts "reel_name: "+reel_name

[beanieboi]

hey,

could you check out the data-streams branch? i added support for data streams there. i need to add some tests before i will merge it, but it works locally for me.

access the reel name ffprobe.data_streams.first.tags[:reel_name]

56

please let me know what you think

[pietrop]

thanks, I'll try it out, any ideas on an ETA for when is this branch going to be merged with the main one?

[beanieboi]

just pushed some tests, will release later today

[beanieboi]

the release is out, thanks for the report. will close this now

[pietrop]

that's great! thank you!

[beanieboi]

you're welcome!
