This would be quite helpful for playback on devices which only support certain codecs in each container.
When using the helper functions for max resolution, merge_output_format: "mp4" is set. On a Roku for exampel, it seems that VP9 is supported but not within an mp4 container. Without the helper it will download the same a/v streams but save them in a webm file instead.
