Profiles

Stack Encode supports ffmpeg setting profiles in the form of YAML files. There are 3 different hashes for the following settings:

• video settings - used for transcoding video files
• audio settings - used for transcoding audio files
• transcoder settings - general transcoder settings

This is an example profile file for stack-encode (my_profile.yml):

---
video:
  resolution: 320x480
  frame_rate: 10
  x264_vprofile: high
  x264_preset: slow
  audio_codec: libfaac
  custom: -movflags +faststart

audio:
  audio_channels: 1
  custom: -ab 48k

transcoder:
  preserve_aspect_ratio: :width

You can use the profile from above like this:

$ stack-encode encode --profile my_profile.yml audio_file.wma
