Output Information

MPDs usually contain multiple AdaptationSet XML tags. Those contain a MimeType of either:

• audio/mp4
• audio/webm
• video/mp4
• video/webm

Within one AdaptationSet there are multiple Representation tags, which then contain information for each representation:

• Bitrate (in Kilobit per second)
• Codec
• Information for Video Only (in ExtraInformation column of generated output):

• Video Width
• Video Height
• Video Frame Rate
