[BUG] Parse and load all sources in Canvas #880

Description

In the IA Manifest there are 3 sources mentioned for the Canvas. However Ramp is only showing 2 options in the quality selector; ogg video and webm. It's not showing the source with the format: "video/mpeg"
Only Chrome and Safari display 2 sources and loads the media from ogg video labeled source URL, while Firefox fails to load the media on page load.
Ramp has the ability to display .mp4 files. Therefore, this error could be due to the format specified for this source URL. And when the format is changed from "video/mpeg" to "video/mp4" in the Manifest, the video gets loaded into the player.

Done Looks Like

• Parse and show all sources in the Canvas
• Investigate and fix the issue with Firefox failing to load any of the sources
• Investigate and fix the issue with MPEG source being unsupported by VideoJS; identify what's causing it to error out
