Spec for AsfLeakyBucketPairs RRS feed

  • Question

  • I am trying to determine how AsfLeakyBucketPairs data in an ASF file is generated.  We have a legacy device that will not play an ASF stream unless this field is present.  However, we can populate the field with garbage and the device will play the stream properly.  Would like to generate the correct leaky bucket data.  I looked at the leaky bucket field in the VC1 sequence header but it only has 1 pair and the value does not correlate to any of the pairs in the data.  Is there a spec that scribes how to generate the AsfLeakyBucketPairs data for the Asf file?
